Hosted at the Reseach Institute and Natural History Museum Senckenberg, Frankfurt. The website includes informations on the IGCP 499 activities, such as informations and photo galleries from previous meetings (including web sites, see below), reports and informations on forthcomming meetings as well as many links to other IGCP projects, institutions and organizations (e.g. UNESCO IYPE, German Science Foundation etc.).
An introductory presentation of the new IGCP took place during the gathering of a good number of members belonging to the International 'Subcommission on Devonian Stratigraphy' (SDS) at an SDS meeting held in Rabat (Morocco) from March 1 to 10, 2004. The meeting was entitled "Devonian neritic-pelagic correlation and events" and organized by Ahmed El Hassani and his colleagues at the 'Institut Scientifique de l'Université Mohammed V, Agdal' including an extended field trip to Devonian key sections in the Dra Valley. 24 oral presentations on Devonian matters including e.g., biostratigraphy, palaeontology, eventstratigraphy, and chemostratigryphy were given during the first two days of the meeting in Rabat. Additionally, 20 posters have been presented touching similar topics. 50 participants from various countries attended this part of the meeting. After the technical sessions an extended fieldtrip to the marvellous Devonian geology of the Dra Valley in the Anti Atlas was attended by 30 participants. The main focus of the trip was set on Lower to Middle Devonian siliciclastics, but minor parts of some sections even reached into the Upper Devonian. An abstract volume and a field trip guide book have been published.
On October 6, 2004 the first business meeting of IGCP 499 was held at the University of Göttingen, Germany, and was attended by about 40 colleagues from 9 countries. The meeting was embedded in the annual meeting of the German Paläontologische Gesellschaft which included a special session on Devonian topics. Presentations and discussions focussed on the activities during the initial phase of the project and how forthcoming activities will be coordinated both, thematically and with respect to future meetings.
International Symposium on "Early Palaeogeography and Palaeoclimate” in Erlangen (Germany, September 1 - 3, IGCP 503), and at the annual meeting of the Geological Society of America in Denver (USA, November 7-10).
The first North American meeting of IGCP-499 - Devonian Land Sea Interaction: Evolution of Ecosystems and Climate (DEVEC) – met in a symposium titled “Correlation of Devonian Marine and Terrestrial Strata” chaired by D. Jeffrey Over at the June 2005 North American Paleontological Convention in Halifax, Nova Scotia.
In the tradition of successful joint meetings and field trips of Devonian IGCP projects and the international Subcommission on Devonian Stratigraphy (SDS) a very successful meeting was held at the Institute of Petroleum Geology, United Institute of Geology and Mineralogy of the Russian Academy of Sciences, Siberian Branch in Novosibirsk. The meeting which included a splendid field trip to the South of Siberia (July 26 – August 6, 2005) and well-organised technical sessions (August 7 – 8, 2005) was run by a great team from Novosibirsk under the guidance of E.A. Yolkin, A.V. Kanygin, N.K. Bakharev, N.G. Izokh and O.T. Obut was entitled “Devonian Terrestrial and Marine Environments: From Continent to Shelf” (DECONS). About 75 scientists (among them 32 colleagues from foreign countries) presented 35 oral lectures and 44 posters. It is planned to publish the results of this conference in a Special Volume (Bulletin of Geosciences, Czech Geological Society) in 2007.
(vi) 6th Baltic Stratigraphic Conference, St. Petersburg (Russia); August 22 – 26, 2005 IGCP 499 has been included this conference that was coordinated by Zivile Zigaite in the framework of IGCP 491 that is focused on mid-Palaeozoic vertebrates (coordinated by Min Zhu and Gavin Young). IGCP 499 was represented by Jurga Lazauskiene who organised a business meeting.
A workshop on „Depositional Environments of the Gondwanan and Laurasian Devonian” has been organized by Prof. Yalcin, our Turkish co-leader. The workshop was attended by about 50 colleagues, mainly from Turkey, but also from Bulgaria, Germany, Lithuania, Morocco, and the USA. There have been about 20 oral contributions and several posters covering major aspects of the subject with a special focus on the Devonian of Turkey and adjacent areas. There were two fieldtrips (Palaeozoic sequences near Istanbul and in the Taurus Mountains, Southern Turkey) offered in conjunction with the meeting. The official part of the field trip was followed by extended fieldwork in the framework of a bilateral Turkish-German cooperation project.
A complete list of participants is continuously updated on the website of the project (/igcp-499). In early Dezember 2006 our list included about 200 scientists from 25 countries. In many countries active working groups excist, in some others also individuals contribute to IGCP (see 3.2.).
In order to follow the suggestions of the project review in 2005 the integration of regional working groups was improved and a strategy for outreach and capacity building has been established.
As indicated in our initial project proposal for IGCP 499, a worldwide network of research groups is essential because the main objectives include a wide range of scientific aspects. To achive the goals of our project a comprehensive network between various specialists, such as palaeontologists, sedimentologists, geochemists and others has been established and the integration of regional working groups has been realized (see below). With respect to the main goals of the project the amount of publications in high ranking journals in 2005 (see report for 2005) and even in 2006 is impressive (see chapter 3.6) and underline both, the multidisziplinary cooperation and the high ammount of publications dedicated to the main objectives of the project listed above. For example, new results on Devonian isotope records with respect to stratigraphy, sea-level change and climate change have been published.
Furthermore, a special volume of Bulletin of Geosciences is in progress comprising the main results presented at our meeting in Novosibirsk 2005. It is planned to publish this volume in 2007. Another special volume will be published in March 2007. This volume entitled “Devonian Event Stratigraphy: Neritic- Pelagic correlations – SDS volume in honour of M. House”, edited by Becker, R.T. & Kirchgasser, W.T. will be published in the Geological Society of London and demonstrate the close cooperation between IGCP and SDS.
The editorial board of Palaeogeography, Palaeoclimatology, Palaeoecology have favorably reviewed a proposal for a special volume dedicated to “Sea-level and Climatic Cyclicity and Bioevents in Middle Devonian Marine and Terresrial Environments”. Furthermore, a special issue which is dedicated to “Case studies in the Devonian” is in preparation and will be published in a Special volume of Geological Society of London.
It should also be noted that participation of “IGCP members” in conferences wordlwide is very high (see abstracts) and also for that reason the visibilty of IGCP 499 is good.
The characterization of facies in marine-terrestrial transitions which is one of the main goals of the project can provided by high-resolution stratigraphy only. Organic-walled microfossils (palynomorphs) are particularly useful for systematic purposes even in those sequences. Additionally, they yield a wealth of information on palaeoenvironmental conditions, including humidity-aridity cycles, and temperatures and nutrient levels of marine waters. A special session has been organized in conjunction with the CIMP General meeting in Praha for two reasons, to promote IGCP 499 and to include those specialists in the project.
Australian working group―focused on an assortment of research of relevance to IGCP 499―can be grouped loosely into four teams.
1. Events team: Talent, Ruth Mawson, Anita Andrew, David Whitford, George Wilson, with Jiri Fryda (Prague) and Lennart Jeppsson (Lund).
The Broken River region of northeastern Queensland has numerous excellently exposed sequences through the Lau (mid-Ludlow) and Klonk (latest Pridoli–earliest Lochkovian) events in the Jack Group, the supposed Choteč (earliest Eifelian) and Kačak (late Eifelian) events in the various tracts of Chinaman Creek Limestone, and of the Taghanic Event (mid-Givetian) in the Spanner Limestone. A comparison of the Choteč and Kačak events as expressed in the Czech and Broken River sequences is to be undertaken in conjunction with Jiri Fryda’s group (Prague). A preliminary account of oxygen isotope investigations of Australian Devonian conodonts was presented at the International Geological Congress in Beijing (Breisig et al., 2006).
Work continues on the Late Devonian Hongguleleng Formation of northwest Xinjiang, China, focused on conodonts, isotopes, macrofossils and sedimentology and determining which if any of the Late Devonian extinction events might be represented. Acid-leaching of the numerous conodont samples collected in 2005 by Chen Xiu-qin, John Talent, Ruth Mawson, Jiri Fryda et al. continues.
A manuscript, long in gestation, on the Lau Event in Gotland and the Broken River region by the team, with Lennart Jeppsson as lead author, was accepted for publication in PalPalPal early in 2006 and should appear soon. Another manuscript on the same event is in preparation. Peter Molloy has submitted his PhD thesis on conodonts through the Ireviken Event as expressed in Boree Ck, northwest of Orange, NSW.
Monographing the taxonomically diverse silicified Devonian gastropod faunas accumulated over the past 35 years by John Talent and Ruth Mawson, is being undertaken by Jiri Fryda (Czech Geological Survey). When this exercise is complete, a statistical analysis of these faunas in association with data from other phyla (especially brachiopods), most already documented, will be undertaken to assess the impact of the Devonian global events on eastern Australian Devonian faunas.
2. Yarrol Team: Paul Blake, Alex Cook, Ruth Mawson, Matthew Ng, Henry Shannon and John Talent.
Work on the Yarrol Basin faunas has proceeded slowly in 2006, though a coral-conodont-gastropod paper on the Mt Etna area, north of Rockhampton, is being developed. Early in the year Henry Shannon re-checked some of his Mt Etna mapping. Ruth Mawson and John Talent continue with identification and documentation of conodont faunas from the, autochthonous and allochthonous carbonate occurrences in the Yarrol Tract, primarily to chronologically underpin Paul Blake’s work on the Silurian–Late Devonian coral faunas.
Zerina Johanson has continued monographing the copious lacustrine fish remains from limestone nodules in the Fairy Formation (Pragian) in the Snowy River Volcanics west of Buchan, Victoria, a locality discovered many years ago by John Talent. The fauna also includes charophytes, ostracods, gastropods and conchostracans. Papers on the oldest coelacanth and a new genus of onychodont are published or are in press.
An MSc thesis on Pragian conodonts from several limestone occurrences in the Bourke-Cobar-Nymagee region was submitted by David Mathieson. This is being developed into a monograph, with Ruth Mawson and John Talent, incorporating other data (bore and outcrop) from the Darling Basin and its eastern flank. A manuscript on the well-preserved silicified faunas of the Booth Limestone is in preparation.
4. Trilobites: Andrew Sandford continues attacking the Silurian–Early Devonian trilobites of Victoria with gusto. Raimund Feist continues to be enormously productive as regards Late Devonian trilobites from the Canning Basin with Rudi Lerosey-Aubril and Ken McNamara.
5. Fish: Fish workers from Australia have been especially active during the past year. The following fish reports have been submitted for IGCP 499. Other reports may be found in the annual report for IGCP 491.
Carole Burrow (University of Queensland) continues collaborating with Sylvain Desbiens (Miguasha Natural History Museum) on the Early Devonian fish faunas of the Gaspé Peninsula, Canada, with Sue Turner (Queensland Museum) on Scottish and Canadian Early Devonian acanthodians, with John Long (Museum of Victoria) and Kate Trinajstic (University of Western Australia) on Middle–Late Devonian acanthodians of Antarctica, and also with John, Mike Coates (Chicago) and Michal Ginter (Warsaw) on a new shark from the Gogo Formation of Western Australia. She continues to work on the histology and morphology of rich Early Devonian microvertebrate assemblages from central west NSW, on the Mike Murphy collection of Late Silurian-Early Devonian acanthodians of the western USA, and on the affinities and distribution of the enigmatic taxon Machaeracanthus. A new project commencing in late 2006 will be a description of the acanthodian taxa from the Emsian of Zinzilban, Uzbekistan in collaboration with Alexander Ivanov (St Petersburg) and Olga Rodina (Novosibirsk). She participated in the ARC Discovery grant-funded field trip to the Cravens Peak Beds of western Queensland in July 2006. These projects involve faunas from wholly marine, transitional and freshwater environments, and are relevant to Devonian biogeography worldwide as well as in marine-nonmarine faunal comparisons.
Kate Loynes (Macquarie University) is commencing an investigation of the abundant fish micro-remains from the Late Devonian Honggulelelng Formation of northwest Xinjiang, China, obtained by acid-leaching of material collected in 2005 by Chen Xiu-qin, John Talent, Ruth Mawson et al., primarily in quest of biostratigraphically well-constrained data on conodonts, isotopes, macrofossils and sedimentology through a long Late Devonian sequence.
Zerina Johanson (Macquarie University) has continued work on some of the fish material obtained by acid-leaching of carbonate nodules from the Early Devonian Fairy Formation (mid-Pragian) of eastern Victoria, including a new onychodont and the oldest known coelacanth. She has recently published (with Per Ahlberg & Moya Smith) a revised phylogeny of Palaeozoic lungfish, focusing on dentition, and is working (with Ann Warren and others) on a new species of rhizodont from the Early Carboniferous of Victoria. With Jean Joss (Macquarie) she is combing neontological (from the living lungfish, Neoceratodus forsteri) and palaeontological data to comment on the putative Devonian larval lungfish, Palaeospondylus (in press). Just begun, with Jean Joss, John Long and Macquarie student Felicity Evans, is a comparison of the morphology and development of the axial skeleton of Neoceratodus with comparable skeletons of Barwickia and Howidipterus.
Sue Turner Queensland Museum) continues work on the earliest shark teeth with Randall Miller (New Brunswick Museum), and on other microvertebrate faunas with Carole Burrow (see above). Full descriptions of Doliodus problematicus and Protodus jexi from the Lower Devonian Atholville beds are in preparation. With Dale Sparling (Minnesota) and Paul Mayer (University of Milwaulkee) she is describing Middle Devonian shark faunas from Ohio and Wisconsin. With Vachik Hairepetian she is describing Late Devonian (early Famennian) thelodont and shark remains from Hodt, Iran. The thelodont part of the Handbook of Paleoichthyology Pt 1 Agnatha, co-authored with Tiuu Märss and Valya Karatajute-Talimaa is nearing publication.
6. Plants: Geoff Playford continues to produce elegant, comprehensive monographs on palynology, mainly Devonian, from around the globe (see Hashemi & Playford, and González et al.). In 2005, a Macquarie-Montpellier group commenced collection and study of Devonian-Carboniferous woods from northern Queensland. Anne-Laure Decombeix presented a preliminary report on superbly preserved Tournaisian woods from ‘Dotswood’ at the International Palaeontological Congress in Beijing (Decombeix et al. 2006). A paper on a Tournaisian permineralised flora and trilobites collected earlier from Ruxton, northern Queensland, will appear soon in Palaeontology (Galtier et al. 2006).
Ongoing research of the German working group concentrated on shallow water sequences in the Rheinische Schiefergebirge and in Turkey. After successful application to the German Alexander von Humboldt Foundation a research award was given to Carlton E. Brett from Cincinnati University (Ohio, USA). Joint projects have been started by the proposing Devonian Group at Senckenberg (Frankfurt) together with him. A first campaign of field work took place in spring 2006 in the Kellerwald and Eifel Hills areas of the Rheinisches Schiefergebirge. In the Kellerwald area the famous section at Blauer Bruch near the town of Bad Wildungen was investigated in order to learn more about the Kacak/otomari Event close to the Eifelian/Givetian boundary and subsequent strata. The locality was revisited and discussed together with O.H. Walliser (Goettingen University) in fall. During springtime first detailed measurements have been undertaken in several sections of the Eifel Hills, again with respect to Middle Devonian strata close to the Eifelian/Givetian boundary and within the lower Givetian. In fall 2006 these sections as well as additional ones have been studied in more detail during C.E. Brett’s second 2006 stay in Germany. But not only sections in the Eifel Hills area have been surveyed – Middle Devonian strata (again focussing on the Eifelian/Givetian transition and on the lower Givetian) of the Sauerland area (Lüdenscheid, Wittgenstein, and Lahn/Dill synclines of the Rheinisches Schiefergebirge) were also investigated. Namely, an upper Eifelian to lower Givetian section in the town of Luedenscheid-Brueninghausen was measured and sampled in great detail. Many of these sections are characterized by limestone and marl alternations and/or other calcareous rhythmitic sequences which might reflect high-frequency environmental change. Therefore, such sequences may offer an ideal tool for high-resolution stratigraphy and environmental reconstruction. Moreover, literature data are re-evaluated for detailed analyses of the prevailing (and migrating) palaeocommunities – the samples of the recent field campaigns will be included in these datasets.
The field work in Turkey is based on the joint research and development project (Devonian ecosystems and climate in Turkey DEVEC-TR, which has been successfully submitted by Volker Wilde and Namik Yalcin in 2005), funded by the Scientific and Technical Research Council of Turkey (Tübitak) and the International Bureau (IB) of the German Ministry for Education and Research (BMBF). The duration of the project is three years (April 2005 – April 2008). The project is devoted to the detailed study and later comparison of selected Devonian sections in Turkey on both, the northern part of the Gondwana block and the southern part of Laurasia. Activities in 2006 included joint laboratory studies in Turkey and in Germany covering slides of rock samples, palynomorphs and conodonts from the previous fieldcampaigns. In early summer fieldwork led a group of participants from both countries to NW-Turkey in the Istanbul and Zonguldak areas. Some sections of putative Laurasian origin were studied and sampled in great detail which are covering sequences from the Silurian to Lower Carboniferous. A special focus will be on the sedimentary record in the Zonguldag and Istanbul area were 5 sections have been investigated. These sections might belong to terranes, but the affinity of the terranes at the SE margin of Laurussia to major continents is uncertain and still a matter of discussion. Comparison and correlation with sections in Southern Turkey – with a special focus on palaeoenvironments, palaeobiodiversity, stratigraphy, and palaeoecology – are the main goals.
A second group returned to three putative Gondwanan sections in the Taurids of S-Turkey which were for the first time visited in 2005 and also include the complete Devonian. The Halevik Section in the Tufanbeyli area has been studied starting with the Silurian/Devonian boundary interval and ending somewhere in the Upper Devonian which is unconformably overlain by Permian limestones. Therefore, a nearby section potentially including the Devonian/Carboniferous boundary has been sampled. The basal part of the Kocadere section near Feke is composed of unfossiliferous eolian sandstones and dolomites of putative Lower Devonian age, but their base is not exposed. The Middle and Upper Devonian of the section include highly fossiliferous strata ranging even into the Lower Carboniferous. While the Halevik and Kocadere Sections are situated in the Eastern Taurids, the Eceli section is belonging to the Central Taurids. At Eceli, the section starts in the Silurian. Major parts of the Lower and ?Middle Devonian are represented by dolomitic laminites including mudmound structures. The section ends in putative Upper Devonian strata. This may be supplemented by a nearby section which is covering the Upper Devonian almost completely but could not be studied in detail due to a lack of time. Throughout this year’s fieldcampaign it was possible to continue the sections at Halevik and Eceli, to fill in some gaps previously left in all of the sections and to do some additional sampling for clarifying questions which appeared when analysing data and samples from the last year. In both areas work on the various fossil groups as well as on other aspects (e.g., sedimentology/facies, biostratigraphy, mineralogical composition, organic geochemistry, XRD, stable isotopes) will continue by studies on the samples of the respective specialists from both Turkish and German sides.
In addition to the field activities in Turkey and the lab work in Turkey and Germany, a joint fieldtrip led four Turkish colleagues to the Devonian of the Rheinisches Schiefergebirge and the tidal flats of the German North Sea. These activities in Germany give important support for a better understanding of the Turkish sections studied by DEVEC-TR.
Carlton E. Brett (Uinversity of Cincinnarti) initiated collaborative research on comparative sequence stratigraphy, faunal patterns, and bioevents in the late Eifelian and early Givetian of the Eifel Hills, Sauerland, Kellerwald area of Germany. The objectives of this study are: a) to test whether patterns of sequence stratigraphy and relative sea-level history in the German sector of Avalonia are comparable to those of Laurentia (Appalachian Basin); b) to test for similar patterns of benthic biotic stability and turnover to those previously documented in the Appalachian Basin; c) to document patterns of stability and change in phytoplankton communities; and d) to determine the local signature and relative severity of global bioevents in different paleocontinents. This cooperative study of stratigraphy and paleoecology is funded by an Alexander Humboldt Prize and conducted jointly with Eberhard Schindler, Peter Königshof, Rainer Brocke, and Volker Wilde of the Senckenberg Institute. During July and August, 2006 several new sections of lower Givetian units exposed by quarrying in the vicinity of Berndorf and Uxheim, Eifel Hills, Germany were surveyed, measured and sampled in detail for microfacies, conodont biostratigraphic, and palynological study. Most samples are now processed and awaiting analysis. In addition, preliminary palynological sampling of age-equivalent strata from a drill core in New York State was undertaken. These samples await processing.
A proposal for a theme volume of papers titled “ Sea-level and Climatic Cyclicity and Bioevents in Middle Devonian Marine and Terresrial Environments” has been accepted by Palaeogeography, Palaeoclimatology, Palaeoecology. This volume will be edited by Eberhard Schindler, Peter Königshof, and C.E. Brett. We hope to have papers for this volume ready for submission early in 2007.
In addition, a new research initiative involving documentation of the taphonomy, sedimentology, and paleoecology of world-famous trilobite beds in the Emsian-Eifelian of the Draa Valley, southwestern Anti-atlas Mountain was proposed by Brett and Schindler. This proposal has been accepted for funding by the National Geographic Society; a joint research expedition in the Draa Valley with colleagues from US, Germany, and Morocco is proposed for March, 2007.
Alex Bartholomew (presently assistant professor at SUNY New Paltz) completed and defended a PhD dissertation on “Sequence Stratigraphy and Bioevents in the Middle Devonian of Eastern North America: Comparison of Appalachian and Michigan Basins”.
This document presents a compilation of sequence stratigraphic and biostratigraphic correlations of the Middle Devonian Givetian Traverse Group strata of the Michigan Basin and the Hamilton Group in New York, Ontario and Ohio. In addition, this work documents the occurrence of ecological-evolutionary subunits in the Michigan Basin which are parallel to and synchronous with those of the Appalachian Basin (two different subprovinces).
Gordon C.Baird (SUNY College at Fredonia) focused most effort in refining and publishing correlations within the latest Givetian-through-earliest Frasnian Genesee Group succession in the Erie County-Genesee County region of western New York through the May, 2006-to-September, 2006 period (see below). In addition, Baird did fieldwork with Alex Bartholomew; this involved the correlation of topmost Eifelian-through-basal Frasnian strata in Tennessee, Alabama, and Illinois (June, 2006). Ongoing work is directed to the mapping of Late Givetian Tully Formation deposits in New York and Pennsylvania.
Previously described (Williams, 1913) recurrence of the Middle Devonian Hamilton fauna within the Upper Devonian Appalachian Basin strata of east-central New York suggested that these faunal recurrences may be distinctive from background Frasnian faunas; that is members of Hamilton and Ithaca faunas do not co-occur. We are currently using methods not available to previous investigations, including sequence stratigraphic and statistical techniques, to confirm such observations.
We are currently focusing upon the non-integrative nature of these faunas and as a tentative hypothesis we suggest that these Tropidoleptus zones record unusual water mass conditions associated with transgressive flooding surfaces. Preliminary outcrop examination began during the summer and fall of 2006 recognizing previously described and widely traceable marker beds. Awaiting confirmation of biostratigraphic analysis, discovery of a possibly correlative deeper water biofacies in western New York suggests establishment of a shallow to deep-shelf lateral gradient in the Upper Devonian Hamilton-like fauna. This research will form the main component of a PhD dissertation by Jay Zambito at the University of Cincinnati.
During the year 2006, Ver Straeten has continued to expand his chief research projects on Emsian-Eifelian strata in the Appalachian Basin (Eastern U.S.) and K-bentonites and Devonian volcanism in eastern North America. Emsian-Eifelian research this year included collaborative field work in the southern part of the Appalachian Basin (with Drs. William Kirchgasser and Richard Lindemann) to collect goniatite cephalopods and dacryoconariids. This is a part of ongoing work to improve international correlations in Eifelian, and especially Emsian strata (which in eastern North America is very poorly constrained). In his K-bentonite work, Ver Straeten continues document Devonian airfall volcaniclastics; and to explore issues related to ash bed preservation in depositional environments, and their implications for filtering the primary record of volcanism.
Other colleagues (Day, J, Whalen, M.T., Over, D. J.) have had the focus on timing of sea level changes in Middle Devonian sequences: The Flume Formation in the Walbridge Mountain area of Kakwa Park in eastern British Columbia has historically been studied as an outcrop analog of latest Givetian-early Frasnian age Swan Hills and Beaverhill Lakes reef platform hydrocarbon reservoirs in the subsurface of Alberta. Recent investigations of the Flume in Kakwa Park indicate that the initial major marine flooding over the Middle Devonian Yahatinda Formation along the southern margin of the Peace River Arch in the Kakwa Park area began as early as the upper part of the Middle varcus and no younger than the hermanni Zone (middle-late Givetian). Maximum flooding of Flume sequence 1 is indicated by brachiopod-bearing calcareous siltstones, with highstand marked by the first appearance of Tecnocyrtina and Desquamatia (D.). A second flooding initiated Flume Sequence 2, with subtidal platform facies that feature a diverse brachiopod fauna including Desquamatia (D.), Tecnocyrtina missouriensis raaschi, and Hypothyridina cf. H. cameroni, capped by prograding stromatoporoid bank carbonates of the lowest Flume reef. The occurrence of H. cf. H. cameroni indicates an age of the initial HST no older than the hermanni Zone. The overlying Flume reefal, lagoonal and reef flat facies succession (Flume Sequences 3-4?), are drowned by a major flooding event represented by subtidal shelf facies of basal Waterways Formation with the brachiopods Tecnocyrtina billingsi and Schizophoria lata. These indicate a correlation with the T. billingsi Zone (no older than late Givetian norrisi conodont Zone) of the Waterways of northeastern Alberta.
The hermanni Zone flooding event of Flume Sequence 2 coincides with a negative oxygen isotope excursion, documented from both brachiopod calcite and conodont apatite in central North America that implies significant global warming. These initial Givetian flooding events along the Peace River Arch have no reported equivalents in Rocky Mountain exposures to the east. The West Alberta Arch in the western Alberta Rocky Mountains appears to have remained sub-aerially exposed until the Upper disparilis Zone flooding that likely initiated Flume sequence 3-4? in the Kakwa Park area. The varcus?-hermanni zones Flume reef cycles probably formed a fringing reef or atoll-like structure around the Peace River Arch prior to drowning in the very late Givetian.
Fluvial and marginal marin deposits have been investigated in Middle Devonian sequences in eastern British Columbia by Lester, Over, Day and Whalen which is an important contribution to marin-terrestrial transitions and shows also the potential of Palynology regarding palaeoenvironments: Deposition of the Yahatinda Formation occurred during the Middle Devonian Watt Mountain Hiatus in western Alberta and eastern British Columbia. The Yahatinda disconformably overlies the Cambrian Ghost River Formation and is disconformably overlain by the Upper Givetian to Fransian Flume Formation. The fern spore Retusotriletes and fern tree Archaeopteris in mudstones and cross bedded sub-lithic arenites indicate a terrestrial fluvial environment. Fish fossils Onychodus and Holonema are shallow marine, but are rounded and broken indicating transport. The peritidal and fluvial mixed sand and gravel of the Yahatinda Formation were deposited in channels carved on the Watt Mountain unconformity surface, and ripple marks indicate a primary flow direction to the south. The source of sediment is the Gilwood Member of the Watt Mountain Formation in the Peace River Arch, northwestern Alberta.
In one of the other projects Missler, R.J. and Whalen M.T. combine litho-, bio-, sequence, and magnetic susceptibility stratigraphy to better understand the pattern and timing of platform (reservoir) development and the influence of terrigenous material on carbonat dominated areas which is a fundamnetal contribution to “land-sea-interactions”.
In Western Canada, Upper Devonian carbonate platforms are significant petroleum reservoirs with related basinal source rocks. The well exposed rock outcrops in the Kawka Lake area of Eastern British Columbia span the Upper Devonian Frasnian-Famennian stage boundary and contain reefal units correlative with the Swan Hills reefal platforms that are productive hydrocarbon reservoirs in the Alberta subsurface. The F-F boundary also represents one of the most significant biotic crises of the Phanerozoic. Various causes for the demise of a wide range of benthic and primarily low-latitude stromatoporoid-coral reefs and pelagic organisms have been suggested including; global cooling, global warming, and extraterrestrial impacts, but none have proven undisputable. The F-F extinction essentially terminated one of the most significant episodes of petroleum reservoir development in Western Canada.
While carbonate platforms are able to keep up with most sea level change through aggradation and progradation, basinal settings generally lag behind due to a lack in sedimentation leaving a bypass or erosional margin in the rock record making stratigraphic correlation difficult. While biostratigraphy is used, it is not always helpful due to the lack of diagnostic conodont species in platform environments and the limited biostratigraphic resolution of stromatoporoids, rugose corals, or brachiopods. Clearly another technique is required in order to gain a better understanding of the depositional environments and the timing of events in the Late Devonian. Magnetic susceptibility stratigraphy provides a means to analyze the timing of depositional events in the Late Devonian to a higher degree of accuracy. With marine regressions comes an increase in erosion resulting in an influx of terrigenous material into the carbonate dominated areas. The continentally derived debris has a greater magnetic susceptibility than the dominantly diamagnetic carbonate material. By comparing the magnetic susceptibility signals from coeval locales we will be able to correlate across basins and with other basins around the world.
The combination of biostratigraphy, lithostratigraphy, sequence stratigraphy, and magnetic susceptibility will improve the stratigraphic resolution of carbonate platforms and in doing so will increase our understanding of the depositional environments, the timing of events, and the controls on source and reservoir rock deposition in the Late Devonian. This will also further our understanding into the pattern and timing of extinctions at the Frasnian-Famennian boundary.
- (Barbieri, Cavalazzi, Ori) Focus of research activity is centered on the Devonian mounds from the Hamar Laghdad Ridge, Anti-Atlas, Morocco. Origin of these carbonate mounds is related to intensive hydrothermal and hydrocarbon events during the Lower and Middle Devonian. The investigations focus on the characterization of fossil microbial communities fueled during Devonian age by hydrothermal/hydrocarbon seepages.
- (Corradini, Gouwy, Perri, Pillola, Pondrelli, Simonetto, Spalletta) Researches are mainly devoted to palaeontology and biostratigraphy in the Carnic Alps and in Sardinia. Biostratigraphic researches are mainly based on conodont fauna in various Devonian intervals; palaeontological investigations deal on various fossil groups, as crinoids, trilobites and brachiopods.
We carried out a geological survey in the Carnic Alps, in order to prepare a geological framework to context the data from stratigraphic sections and allow basin analysis. Some black organic layers have been mapped for the first time: such levels could possibly correspond to the Devonian events documented in many classical areas in deep basinal facies. In order to understand their significance in terms of stratigraphy and paleoenvironmental evolution, we undertook detailed sedimentological and stratigraphical analysis in correspondence of these sections and their shallower (mainly forereef facies) lateral counterpart. The aim is to evaluate the eventual relations between possible tectonic event, sea level fluctuations and mass extinctions.
In Sardinia, a revision of Famennian and Tournaisian conodont biostratigraphy in the island and its implication for a regional conodont zonation is in press. Conodont researches deal on Lower Devonian of SW Sardinia and on a Middle Devonian fauna from South-East Sardinia. Devonian/Carbonferous boundary beds in the Monte Taccu area are re-studied in order to try to solve some biostratigraphic problems acrss the boundary. Studies on a Lower Devonian fauna with brachiopods and trilobites are in progress.
A first report on Famennian conodonts from Bosnia have been published, and a project on graphic correlations of some Frasnian sections from the eastern Anti-Atlas (Morocco) is carried on.
The Russian working group continued field work in sections of the Altai region and in East Kazakhstan, focusing upon stratigraphy and palaeoenvironmental reconstructions. Mainly Middle and Upper Devonian sections have been examined in West Siberia. Several papers are submitted (special volume on the Novosibirsk meeting), or in progress.
During this year the Spanish working group has been very active, as can be inferred from the high number of publications (37) and presentations (17) at professional meetings (see references).
Most of the publications deal with the Devonian Correlation Table and present an state-of the-art in the dating of Devonian lithoestratigraphic units of the southern part of the Pyrenees. Other better known regions, such as Cantabrian Mountains, the Iberian Chains are also considered.
Participation in Professional meetings were focused in the three more relevant meetings for the group: II International Palaeontological Conference in China, 2006 ICOS in Leicester (UK) and Spanish Society of Palaeontology Anual Meeting in León. Additionaly a talk was presented at the 76. Jahrestagung der Paläontologischen Gesellschaft held in Kiel.
In the IPC, the Spanish group was represented by the leader of the group (Prof. Dr. José Ignacio Valenzuela-Ríos) and by the Secretary (Jau-Chyn Liao). Both participated in the pre-conference field-excursion to the Devonian of the Guilin-Xiangzhou area in South China, where numerous Devonian sections and localities were examined, as well as the parastratotype section for the Devonian/ Carboniferous boundary at Nanbiancum.
In the special IGCP Symposium (T7) within the IPC, the Spanish Working Group presented four works (three as a talk and one as a poster).
In the 2006 ICOS host at Leister, the Spanish Working Group, represented by five members (Valenzuela-Rios, Liao, Carlos Martínez, Javier Sanz López and Silvia Blanco) attended the special session on Devonian Biostratigraphy organized by P. Bultynck and participated in the SDS business meeting. Four papers related to the IGCP were presented (all as oral presentations).
Last but no least, the Spanish Working Group organized a especial IGCP 499 Symposium within the Annual Meeting of the Spanish Palaeontological Society. This special Symposium was attended by many members of the group and other colleagues that joined us both, in the sessions and in the field trip. Eight papers were presented, and a field-trip to the Lower Devonian of Colle was organised by members of the León and Oviedo Universities.
Also, it is remarkable that the Spanish Group has grown this year, as three members from the Geological Survey of Spain approached the leader to become members of the group.
Pierre Bultynck and Katarzyna Narkiewicz have been working on the correlation of shallow marine and pelagic sequences by means of conodonts. A direct positioning of the late Givetian-earliest Frasnian hermanni, disparilis and lower falsiovalis conodont zones, established in pelagic successions, in shallower-water marine successions is almost impossible. Skeletognathus norrisi, an ubiquitous species, can be helpful for recognizing the lowest part of the falsiovalis Zone in shallower-marine environments. However, for shallower-marine environments there is mostly a need for an alternative conodont zonation for the late Givetian-earliest Frasnian.
In North America the Pandorinellina insita Fauna is considered as a shallow-water equivalent for the lowest part of the falsiovalis Zone and the Icriodus subterminus Fauna as a shallow-water equivalent of the disparilis Zone and may be also of the hermanni Zone.
Until now the subterminus Fauna has been only well documented from the central and western North American Interior Bassins. Our purpose is to document the subterminus Fauna outside North America and to define more precisely its lower boundary and subdivisions in relation to the pelagic zonation. Moreover Icriodus subterminus as used at present is a long ranging species: hermanni? and disparilis to Lower rhenana Zones. Therefore a revision of Icriodus subterminus and other accompanying conodont taxa may improve the stratigraphic use of the subterminus Fauna.
During 2006 we recognized Icriodus subterminus and closely related forms in published and new collections from Europe and southern Morroco, more precisely in the Boulonnais area (NE France), Ardenne area ( Belgium and NE France), the Radom-Lublin area (SE Poland, the Holy Cross Mountains ( S Poland) and the N Tafilalt and Mader in Morocco. Our study is also based on Icriodus subterminus Fauna comparison material from Iowa, Manitoba and NE Alberta.
1- Within Icriodus subterminus we recognized four morphotypes. Two short, stout morphotypes may have a more restricted stratigraphic range.Two more elongated morphotypes may not appear at the same level and range higher in the Frasnian.
2- In the subterminus material from Canada Uyeno (1981, 1982, 1983) recognized an Icriodus cf. Icriodus subterminus including specimens that can be assigned to Icriodus lilliputensis ( described from the Ardenne area) and to Icriodus excavatus (described from Europe and Iran). The other specimens are assigned here to Icriodus aff.Icriodus subterminus.For the moment it is not clear whether or not Icriodus aff.Icriodus subterminus has the same range as the different Icriodus subterminus morphotypes.
3- Co-occurring Icriodus taxa including I. brevis, I. excavatus, I. lilliputensis, I. difficilis, I. expansus, I. n.sp.A used in a more precise way and considering their first and last occurrence may be helpful to precise subdivisions of the subterminus Fauna.
4- The origin of Icriodus subterminus is not yet clear. At present we consider Icriodus lilliputensis as closely related to the short, stout morhotypes of Icriodus subterminus, based on the succession with overlapping of the two taxa in an Ardenne section. Relations with Icriodus excavatus may be possible.
5- In Europe Icriodus subterminus appears at some localities below the insita Fauna but also within the insita Fauna.In the Morrocan Tafilalt Icriodus subterminus first occurs together with Skeletognathus norrisi in an hemipelagic facies. In the Mader Icriodus aff. I. subterminus occurs together with Schmidtognathus wittekindti.In the Radom-Lublin area Icriodus aff.I. subterminus occurs together with Polygnathus timorensis indicating that it is not younger than the hermanni Zone.
6- Migration of Icriodus subterminus between N America, Europe and N Afrika and also biofacies changes have to be considered in interpreting the local stratigraphic base of the subterminus Fauna. But this topic has to be further investigated.
Alain Blieck (Lille) continues work mostly on Devonian vertebrates (IGCP 491) but many of his contributions have also relevance for the IGCP 499 (see references), such as his work on vertebrate microremains and his work on Early Devonian vertebrate biodiversity. A cooperation with other members of the IGCP 499 group exist, e.g. the French-Lithuanian cooperative project on Middle Palaeozoic Vertebrates of Eurasia.
In order to itensify cooperation between China and Germany a session (T7) on Devonian land-sea interaction: evolution of ecosystems and climate was held on June 17, 2006 in conjunction with the International Palaeontological Congress (IPC) in Beijing, China. The successful and enjoyable session (21 oral and poster presentations) took place in the Yingjie Conference Centre. There was a large positive response to our call, and the convenors of the session (Peter Königshof and Xueping Ma) could welcome more than 30 colleagues from Australia, Canada, China, European countries and the USA. Far more talks were offered than could be accommodated in the single-session programme. Finally 15 talks on a wide range of topics with numerous new data and stimulating scientific ideas, e.g. on carbon isotop stratigraphy, climate fluctuations, sedimentology and microfacies, palaeoecology and mass extinction events were presented. The abstracts of the contributions to the T7 session are published in the IPC abstract volume (Qun Yang et al. (eds.): Anchient life and modern approaches – Abstracts of the Second International Palaeontological Congress. University of Science and Technology of China Press; 1-553). All in all, the IGCP 499 session was highly successful: it brought together people from a wide range of countries and experience in various disciplines, covering the main topics of the project. Furthermore, during the “business meeting” the schedule of the next meetings and the strategy concerning data processing and publications, such as special volumes were presented. The topical session was partly supported by the German Science Foundation (DFG). A pre-conference field-excursion has been organized focusing on the Devonian of the Guilin-Xiangzhou area in South China, where numerous sections and localities were examined.

The intension of participation in this workshop was to stimulate a closer cooperation between palynologists and other specialists who are already involved in the project. Palynology can play an important role in determining marin – non marine sequences and for correlations between different very shallow water realms. Therefore, IGCP 499 organized a special session in conjunction with the CIMP General Meeting in Praha. The meeting was organised by Jiri Bek, Rainer Brocke, Jirina Daskova and Oldrich Fatka. More than 40 participants from 7 countries attended the special session which was held on September 4, 2006: 6 talks were given and 4 posters were presented but not all contributions related to IGCP 499 topics could be grouped in this session. On overview on the past and future IGCP 499 activities were presented, and an introduction in the next fieldmeeting which will take place in Argentina in May 2007 was given. At the end of the session the IGCP 499 business meeting took place.

During the Opening Meeting of the IGCP 503 at Erlangen, IGCP 499 presented informations on the project and forthcomming activities. A successful joint meeting of IGCP 499 and the international Subcommission on Devonian Stratigraphy (SDS) was held at the Institute of Petroleum Geology, United Institute of Geology and Minerology of the Russian Academy of Sciences, Siberian Branch in Novosibirsk, Russia. Most IGCP participants are titular or corresponding members of the national and international SDS. A joint meeting of IGCP 499 and IGCP 497 (“The Rheic Ocean”) which will be held in 2008 is in preparation. For that reason two field excursions in the Rheinisches Schiefergebirge, and the Saxothuringian area took place in this year. There is also a strong link to IGCP 503 and a special session with one of their meetings is planned.
As indicated in our project proposal work on understanding the patterns of climate change in the Devonian, palaeoecosystems, and land-sea transitional settings will continue through the duration of the project. In the next year we will concentrate on transitional/shallow marine settings and correlations with open marine settings and we will focus on sea level changes and bioevents. Another focus of the next year will concentrate on different palaeoecosystems in different palaeogeographic settings. Therefore, one of our field meetings will take place in Argentina. A seven day post meeting field trip will be offered to show Palaeozoic sections (Malvinokafric Province) with a special focus on Devonian siliciclastic sequences.
The deadline for registration is December, 20-2006 and a large number of participants from developing countries, preferably from South-America is expected.
http://www.geneseo.edu/CMS/display.php?dpt=frasnian. It is expected that many SDS members and IGCP 499 members will participate in the conference.
May/June: SDS/IGCP joint fied workshop in Central Asia.
August: IGCP business meeting and special session in conjunction with the International Geological Congress, Oslo (Norway).
October: Field meeting and conference in conjunction with IGCP 497 (Rheic Ocean), Frankfurt, Germany.
Based on the extensive activities and the increasing number of post-graduate students and graduate students involved in this project, e.g. from Turkey, Russia and South-America, we want to apply for higher funding. Based on the funding in 2006 we will not be able to invite colleagues from developing countries to participate in the conferences in Argentina and United States.
Not relevant for IGCP 499.
The IGCP Scientific Board would like to be informed how the IGCP funds were used and if additional funding could be obtained from different sources.
The IGCP funds have been used mainly for travel expences for colleagues from developing countries and PhD students. The allocated sum was used for travel and/or subsistence costs only of invited participants in the meetings (the meetings-report form and the financial statements have been submitted to IGCP Secretary and IUGS on September, 20th – 2006). For their own travel expances the leaders applied for additional funding, so that 100% of the UNESCO/IUGS buget has been used for the project itself. Additional funds have been obtained from TÜBITAK, the International Bureau of the German Ministry for Education and Research (BMBF), and Natioanl Geographic Society.
In the next year, a touring exhibition on German IGCP`s will be prepared. This exhibition will partly be funded by the German Science Foundation (DFG).
