title: Isotopic signals from Callovian–Kimmeridgian (Middle–Upper Jurassic) belemnites and bulk organic carbon, Staffin Bay, Isle of Skye, Scotland

description: The stable isotope data presented here significantly extend and expand upon previous isotopic investigations of the Middle to Late Jurassic interval. The belemnite samples collected from the Staffin Bay and Staffin Shale formations from the Isle of Skye, Scotland, yielded oxygen isotope values consistent with Callovian–Kimmeridgian palaeotemperatures of 6.7–20.6 °C. The carbon isotope data comprise one of the first moderately high-resolution investigations of the relationship between terrestrial δ<sup>13</sup>C<sub>org</sub> (predominantly fossil wood debris) and marine δ<sup>13</sup>C<sub>carb</sub> (belemnites) as derived from a geologically coeval record. The Staffin Bay data reveal a broad Early to Mid-Oxfordian positive carbon isotope excursion. The excursion maximum occurs in the <em>cordatum</em> Zone (British Boreal ammonite zonation), although high values persist into the <em>tenuiserratum</em> Zone. The correspondence between the marine and terrestrial records indicates a strong coupling of the ocean–atmosphere system and suggests that the total exchangeable carbon reservoir would have been affected at this time. The Mid-Oxfordian negative carbon isotope excursions identified in published Tethyan records and commonly attributed to methane release are not recorded in the Staffin Bay data, which may suggest that the Tethyan excursions do not represent fluctuations in the global carbon reservoir and that the fidelity of the methane hypothesis should be re-evaluated.

title: Devonian arc-related magmatism in the Tseel terrane of SW Mongolia: chronological and geochemical evidence

description: The Tseel terrane in the Gobi Desert of SW Mongolia consists of a composite crustal segment of imbricated sheets of high- and low-grade metamorphic rocks of predominantly middle Palaeozoic age. New sensitive high-resolution ion microprobe (SHRIMP) zircon ages of 396 ± 3 Ma (2σ) and 397 ± 3 Ma (2σ) for two calc-alkaline metarhyolite samples indicate arc volcanism during the early Devonian. An undeformed feldspar porphyry cross-cutting the early Devonian low-grade sequence yielded an emplacement age of 279 ± 2 Ma (2σ). Geochemical and Nd isotopic data for low-grade mafic metavolcanic rocks are consistent with melting of moderately depleted upper mantle sources in a transitional arc–back-arc setting. In addition, there are high- and low-grade felsic metaigneous rocks with subduction-related chemical signatures and heterogeneous Nd isotopic compositions indicating an origin from mixed sources, including juvenile and Precambrian crustal components. The field observations combined with the geochemical and isotopic data suggest that the Tseel terrane represents a segment of a mature Japan-type arc associated with a juvenile back-arc basin.

title: Evidence for an early Archaean granite from Bastar craton, India

description: Granitoids in the early Archaean are believed to be potassium-poor tonalite–trondhjemite–granodiorite rocks. Only after continental crust attained sufficient thickness did true (relatively potassium-rich) granites form. No record of true granite prior to 3.4 Ga is available. We report a 3.6 Ga true granite from the Archaean Bastar craton in India. In contrast to the typical early Archaean granitoids, which are commonly deformed into gneisses, this granite is relatively undeformed. The age and composition of the granite implies that continental crust of the Bastar craton attained sufficient thickness to permit intracrustal melting at 3.6 Ga.

title: Reverent and exemplary: ‘dinosaur man’ Friedrich von Huene (1875–1969)

description: Friedrich Freiherr (Baron) Hoyningen, better known as von Huene, was a palaeontologist who made major contributions to vertebrate, especially amphibian and reptile, taxonomy. He was the dinosaur doyen of the Institute and Museum of Geology and Palaeontology, University of Tübingen, and an important figure in the German scientific community for seven decades. Unlike his peers, he was a pious evangelical Protestant whose life and research were strongly influenced by his beliefs, which were unusual for a scientist in the 20th century and even for most contemporary Christians, and which he maintained throughout his life. His body of scientific and religious work and his correspondence with colleagues such as Tilly Edinger and Richard Lull, and the self-taught vertebrate palaeontologist Heber A. Longman in Australia, give insights into and contrasts to his thinking, and throw light on scientific exchange in general as well as von Huene's philosophy, personal beliefs, hopes and dreams, and on how he coped with the Third Reich. Longman, a professed agnostic, was mentored by von Huene during his early work on vertebrate taxonomy at the Queensland Museum. Their relationship lasted more than 25 years, although they never met. Unlike other 20th-century ‘life’ scientists, von Huene's scientific work and career were affected by his religious philosophy. <strong>Supplementary Material</strong>: Huene bibliography is available at http://www.geolsoc.org.uk/SUP 18336.

title: Middle Devonian microfloras and megafloras from western Argentina and southern Bolivia: their importance in the palaeobiogeographical and palaeoclimatic evolution of western Gondwana

description: The study of microfloras and megafloras from western Argentina and southern Bolivia presented here extends our knowledge of the biodiversity and succession of floristic events during the Middle Devonian, and hence improves the current biostratigraphy. Among floral remains, species attributable to ‘<em>Haplostigma</em>’ are mostly recorded from the same <em>Grandispora pseudoreticulata</em> and other palynomorph-bearing sections at Balapuca (southern Bolivia) and Del Chaco and La Cortadera creeks in the Precordillera of Argentina. The northernmost record of <em>Grandispora pseudoreticulata</em> is recorded from a third palynoassemblage from the Pando x-1 corehole of northern Bolivia. A great similarity among all these assemblages (notably abundant <em>Grandispora pseudoreticulata</em>) suggests the identification of terrestrial connections, or at least proximity, of these local areas and other regions in South America during the Givetian. Comparison with other contemporary Gondwanan palynofloras shows cosmopolitan species (e.g. <em>Geminospora lemurata</em>, <em>Samarisporites triangulatus</em>, <em>Archaeozonotriletes variabilis</em>, <em>Chelinospora concinna</em>) along with some others with more restricted distribution (e.g. <em>Grandispora pseudoreticulata</em>, <em>Leiotriletes balapucensis</em>, <em>Acinosporites ledundae</em>). This pattern defines an Afro-South American Subrealm, which most likely results from the effects of palaeolatitude and, in a lesser way, local palaeoenvironmental conditions. On the other hand, such a level of cosmopolitanism supports previous palaeogeographical reconstructions where a narrow Rheic Ocean was developed between Euramerica and the northern parts of Africa and South America.
