# Paleobiota of the Posidonia Shale

The Sachrang Formation or "Posidonienschiefer" Formation (common name the "Posidonia Shale") is a geological formation of southwestern Germany, northern Switzerland, northwestern Austria, southeast Luxembourg and the Netherlands, that spans about 3 million years during the Early Jurassic period (early Toarcian stage). It is known for its detailed fossils, especially marine biota, listed below. Composed mostly of black shale, the formation is a Lagerstätte, where fossils show exceptional preservation (including exquisite soft tissues), with a thickness that varies from about 1 m to about 40 m on the Rhine level, being on the main quarry at Holzmaden between 5 and 14 m. Some of the preserved material has been transformed into the fossil hydrocarbon jet which, especially jet derived from wood remains, is used for jewelry. The exceptional preservation seen in the Posidonia Shale has been studied since the late 1800s, finding that a cocktail of chemical and environmental factors led to such an impressive preservation of the marine fauna. The most common theory is that changes in the oxygen level, where the different anoxic events of the Toarcian left oxygen-depleted bottom waters, stopped scavengers to consume the dead bodies.

## Biological interactions

* The "Monotis"-Dactylioceras bed shows an accumulation of the bivalves Meleagrinella substriata and the ammonite Dactylioceras, that were the most abundant representatives of its group on the Altdorf region, and were probably washed to near epicontinental waters by a rapid event, or as result of a large succession of events. This assemblage has been compared with modern Brazilian coastal mangroves and also linked to tsunami events.
* Several empty ammonite shells from Holzmaden have been found with associated decapods inside. This includes a possible member of the genus Paleastacus inside a chamber of a Harpoceras. This decapod is related to the family Erymidae, which are considered to be possible bottom-dweller carnivores or carrion feeders. The associated fossil has several spherical structures that had been interpreted as decapod coprolites, implying that the animal lived for a long period within the shell. More recent studies had recovered new data about the inquilinism of decapods inside ammonites, this time, however, recovering three eryonoids together within a body chamber. The eryonoids most likely used the ammonoid as some kind of shelter, possibly due to the shell being an ideal location to molt, protection against predators, a source of food or that the shell was used as a long-term shelter. One key aspect found was that the muddy bottom was not suitable for burrowing, implying that the decapods inhabited a different shelter due to being unable to make their own. Other biota are found related to the decayed ammonite shells, such as serpulid annelids and bivalves, creating what was denominated as "benthic islands".
* Beyond trace fossils, several vertebrate specimens show associations with crustacean exoskeletal remains such as GPIT-PV-31586 and SMNS 58389 (Pachycormus macropterus) with necrophagous interaction as well SMNS 55934 (Stenopterygius quadriscissus) or SMNS 95401 (Metopacanthus sp.).
* The genus Clarkeiteuthis and its predatory behaviour, found associated with fishes of the genus Leptolepis. Based on the position of prey and predator, it was suggested that the cephalopods caught and killed the fishes while the schools were still in well-oxygenated waters and then descended into oxygen-depleted water layers where the cephalopod suffocated and died attached to its prey. The cephalopods’ arms were contracted over the fish, likely killing it quickly by cutting its spine.
* Several Geotheutis have been reported with eumelanin preserved along with their ink sacs.
* A specimen of Jeletzkyteuthis found in Ohmden has appeared predating a Parabelopeltis. The association of these 2 genera shows the predatory behaviour of this group when its members lived in epicontinental seas, which is rather different than extant Vampyromorphs.
* A pabulite (fossilized meal which never entered the digestive tract) was recovered from Holzmaden, being composed of an associated Passaloteuthis laevigata with its arms embracing an exuvia of a crustacean. The belemnnite itself can be seen as the remnant of a failed predation attempt from a Hybodus, corroborating a possible tropic chain.
* One of the most complex organism interactions on the Posidonia Shale were the crinoid megarafts that grouped a wide variety of animals, creating large floating ecosystems. The largest megaraft found measured 18 metres (59 ft), and is based on an Agathoxylon trunk, where different animals were attached. The first attached animals would have been the growing community of oysters, bivalves and crinoids, that would add a small weight to the raft (about 800 kilograms (1,800 lb)). The presence of these megarafts were in part possible due to the absence of marine wood worms which destroy tree logs in less than 3 years along with the absence of modern raft wood predators (that appeared on the Bathonian). These rafts could last up to 5 years, which is the main reason the crinoids attached were able to reach huge sizes. These rafts were likely also essential to distribute animals along sea basins. Seirocrinus & Pentacrinites were some of the main crinoid colonizers of the floating rafts. Seirocrinus is the main representative of the pelagic crinoids, being among the longest animals known, reaching 26 m long in the largest documented specimen. The ecology of the genus is widely known, with it being known that the smallest stems were among the first animals to colonize the rafts, with at least 2 generations of crinoids found per raft, where the hydrodynamic changes of the log influenced the settlement of the crinoids. It is believed that Seirocrinus underwnt seasonal reproduction linked to monsoonal conditions that sent new logs to the sea. The large crinoids would have feed on pelagic micronutrients, and after the log fell to the bottom, all of the colony would have died.
* Thoracic barnacles of the genus Toarcolepas became the oldest epiplanktonic barnacle known in the fossil record, probably motivated by the appearance of the giant crinoid rafts. It has been found in situ associated with fossil wood.
* The shark Hybodus includes specimens with gastric contents full of belemnnite fragments. This implies active predatory behaviour by the genus towards several kinds of belemnnites, such as Youngibelus.
* A spienballen (a regurgitated mass composed of indigestible stomach contents) had been found in the Holzmaden quarry. The speinballen measures 285 mm in length with a diameter of 160 mm, and consists of 4 members of the genus Dapedium (Dapediidae) and a jaw identified as Lepidotes (Semionotidae). The maker of this spienballen has been suggested to be a shark like Hybodus, an actinopterygian or a marine reptile.
* A specimen of Pachycormus has been found with stomach contents that include hooks similar to the ones found on genera like Clarkeiteuthis.
* Another specimen of Pachycormus macropterus preserves an ammonite inside its gut, likely swallowed by accident and directly responsible for the fish’s death.
* SMNS 51144 (Saurostomus esocinus) was found with Chondrites sp. burrows in the abdominal cavity, what indicates a possible opportunistic scavenger. Other Chondrites sp. includes SMNS 17500 and MHH 1981/25 (Stenopterygius uniter) that either suggest the ichthyosaurs were preserved immediately below one such bioturbation horizon or scavenger association.
* The known specimens of Toarcocephalus are evidence of successful predation events, as the head of one was isolated, likely as product of a decapitation, with another preserved within a regurgitated mass.
* One of the most emblematic finds of the formation is that of a mother Stenopterygius giving birth to live young. While specimens have been found with embryos, the bones of these embryos are scattered partly beyond the body limits of the mother. There have been various theories about this scenario: either the bones of embryos had been deposited before the body of the adult went to the sea floor, or in the ichthyosaurs’ last moments where it sank to the bottom and may have given untimely birth to some of the foetuses, and finally another option follows post mortem hydrostatic pressure being too high to be prevented by the body, exploding or expelling its embryos.
* The specimen SMNS 53363 (Eurhinosaurus?) from Aichelberg was found with two encrusted large oysters (Liostrea) on the right pterygoid, considered to be part of a reef stage over bones.
* SMNS 80234 (Stenopterygius quadriscissus) represents another female with embryos, yet also shows ribs broken perimortem that may represent either intraspecific aggression or a predation attempt. This specimen has several taxa associated: ammonite aptychi, two ophiuroids (Sinosura brodiei) and a articulated echinoid (Diademopsis crinifera) indicate a short-lived deadfall community.
* SMNS 81841 (Stenopterygius quadriscissus) represents one of the clearest examples of deadfall communities described in the formation: the skeleton is associated with serpulids surrounded by a mass of disarticulated ophiuroid remains, indeterminate echinoid tests, an isolated crinoid ossicle, the byssate bivalve Oxytoma inaequivalvis, the pectinid Propeamussium pumilus, Eopecten strionatis, Plagiostoma sp., Meleagrinella sp., "Cucullaea" muensteri, with the genera Parainoceramya dubia and Liostrea associated with the carcass. As many of these bivalves show overgrowth the community likely persisted for some time. Fossil traces of Gastrochaenolites isp. attributed to mechanical bivalve borers are abundant implicating prolonged exposure of the skeleton on the seafloor.
* SMNS 81719 (Stenopterygius uniter) includes Liostrea, Propeamussium pumilus, Plagiostoma sp. and Parainoceramya dubia, with other invertebrates found (?) not being part of the deadfall community, such as several ammonites and Parainoceramya valves, being stratigraphically below the specimen. This specimen includes also traces of scavenging activity, possibly by crustaceans.
* SMNS 80113, (Stenopterygius triscissus) was found populated by Parainoceramya, a specimen of Eopecten strionatis and an unexpected specimen of the small infaunal lucinid Mesomiltha pumila, equivocal evidence for the sulfophilic stage.
* Local ichthyosaur soft tissues include skin enough well preserved to infer coloration and appearance on the living animal, as well evidence for homeothermy and crypsis.
* Gut contents of the local pterosaurs are known: Campylognathoides preserves hooks of the coleoid Clarkeiteuthis (therefore being the one of the few teuthophagous pterosaurs), while Dorygnathus preserves remains of Leptolepis.

## Microbial activity

Non-fenestrate stromatolite crusts formed in aphotic deep-water environments during intervals of very low sedimentation are recovered in places such as Teufelsgraben, Hetzles. The stromatolites of this region have evidence of live on a deeper shelf environment with a quietwater deposit which suffered repeated phases of stagnant bottom waters, where a depth water habitat developed, probably at more than 100 meters depth. There is a thin, southern widespread stromatolite crust on the top of the Sachrang Formation, called "Wittelshofener Bank", that has made researchers rethink the depth of the major southern basin of the formation, where the absence of phototrophic calcareous benthic organisms (probably due to the lack of light) shows the depth of the basin. On the "Wittelshofener Bank" there is also the only occurrence of ooids, presumably formed in the same deep-water environment.

| Frutexites | F. arboriformis | Teufelsgraben, Hetzles | Possible traces of Microbial Activity | Probably related with archaeal activity. Although Frutexites is a cryptic microfossil and an important element of many deep water stromatolites, with an inorganic origin proposed it was interpreted as dendritic shrubs of purely inorganic growth of aragonitic crystals, but it also resembles shrubs of the cyanobacteria Angulocellularia. In the Posidonia Shale a cryptoendopelitic mode of life is assumed, being only possible for heterotrophic bacteria or fungi. As seen in the stromatolites of the Posidonia Shale, Frutexites acted mainly as a dweller or secondary binder of the deep-water stromatolites, not as their major constructor. | |

## Dinoflagellata
### Dinoflagellate cysts

The evolutionary burst of the Toarcian dinoflagellates led the first appearance and rapid radiation of the Phallocystaceae (Susainium, Parvocysta, Phallocysta, Moesiodinium and related forms). This occurred at the time of a widespread Lower Toarcian bituminous anoxia-derived shale, which is recovered from the Posidonienschiefer, Pozzale, Italy, Asturias, Spain, Bornholm, Denmark, the Lusitanian Basin of Portugal, the Jet Rock Formation in Yorkshire and to the "Schistes Carton" in northern France. Whether there is a causal connection in this co-occurrence of Phallocystaceae and bituminous facies is a problem still to be resolved. This family has its acme in diversity and quantity in the latest Toarcian and became less important in the Aalenian.

## Fungi

Fungal spores, hyphae and indeterminate remains are a rare element of the otherwise open marine deposits of the Posidonienschiefer formation, but were recovered at Dormettingen. These fungal remains are composed mostly of indeterminate spores and indicate oxygenated environments and suitable transportation by rivers.

## Ichnofossils

The major ichnological analyses of the Posidonian Shale come from Dotternhausen/Dormettingen, where the ichnogenus Phymatoderma formed the so-called Tafelfleins and Seegrasschiefer. The Tafelflein bed was deposited under anoxic bottom and pore water, where a recover of oxygen allow the Phymatoderma-producers return. The two organic-rich layers (Tafelfleins and Seegrasschiefer) are characterized by the dense occurrence of trace fossils such as Chondrites and Phymatoderma, done episodically due to the fall of the oxygen levels. The coeval more nearshore Swiss deposits referred Posidonian Shale (Rietheim Member) hosted similar trace fossils to those recovered on SW Germany. Ichnofossils in this setting apparently evolved faster to more oxic-to-dysoxic bottom waters. At Unken, laminated deposits of red limestone suggest well oxygenated active waters (as they lack shale), where high amounts of Chondrites are found.

## Invertebrata
### Porifera

In the non-bituminous facies located on Obereggenen im Breisgau (Shore of the Black Forest High), especially the lower semicelatum subzone, pyritized individual needles of silica sponges (Demospongiae and Hexactinellida) are found, rarely on pelagic layers to very often on the low depth marine deposits. They are usually associated with radiolarian stone cores. In Dusslingen and Reutlingen, these sponge needles are sometimes barytized in phosphorites of the Haskerense subzone and are much more common here than in any other zone of the Lower Toarcian. These needles are absent in the bituminous horizons of the entire Lower Toarcian. Increased amounts of sponge needles (dominated by Hexactinellida) are also found on the arenaceous facies of the nearshore unit that is the Unken member, being the only section if its region hosts them, probably due to be an active and well oxygenated bottom. The location of this member as a possible bay on the south of the vindelician land probably allow to the development of more pre-Toarcian AOE conditions, hence the presence of biota otherwise rare on bituminous layers.

| Antiquilima | A. sp. | Dotternhausen | Shells | A Limidoid file clam. | |
| Bositra | B. buchii B. radiata | All the Formation | Shells | A posidoniid ostreoidan. It is the type fossil of the Sachrang Formation. Originally it was named "Posidonia bronni", thought to be a new genus, and the strata were denominated the Posidonia layers after it. Years later it turned out to be a junior synonym of Bositra, and thus it was reassigned. However, the name of the layers was retained. The habitat and mode of life of Bositra has been debated for more than a century. There have been different interpretations, such as a pseudoplanktonic organism, a benthic organism living on the open marine floor, where it was the main inhabitant of the basinal settings, and a hybrid mode, where it had a life cycle with holopelagic reproduction controlled by changes in oxygen levels, and even a chemosymbiotic lifestyle with the large crinoid rafts being the main “safe havens” to evade anoxic events. Various hypotheses along the years led to a large study in 1998, where the size/frequency distribution, the density of growth through lines related to the shell size and the position of the redox boundary by total organic carbon diagrams revealed that Bositra probably had a benthic mode of life. | Thousands of specimens in one matrix |

Being the second most common genus of bivalve in the Formation, it has been subject to several studies in regards to its ecological niche, similar to Bositra. Several opinions include a pseudoplanktonic-only organism able to live in the open sea, or a benthic-only organism. Within the 1998 evaluation with Bositra, was found that this genus probably had a benthic juvenile stage that transitioned to a faculatively pseudoplanktonic adult. | Single specimen |

### Echinodermata

Echinoderm debris is relatively abundant in the shale-free Unken and Salzburg members, including crinoid and brittle star skeletal elements; sea urchins take their place later in the formation, with them having especially diversified at that time, leading to pedicellaria being observed very often.

| Seirocrinus | S. subangularis | Banz Altdorf Mistelgau Aichelberg Schandelah Dotternhausen Holzmaden Ohmden Maurach | Various complete and nearly complete specimens, some associated with rafts | The largest known crinoid, from the family Pentacrinitidae. Seirocrinus consists of fossils in colonies along large wood trunks, with specimens up to 14 m long and the largest reaching 26 m, which makes it among the tallest known Mesozoic organisms, one of the largest invertebrates known in the fossil record and one if the tallest known animals. It was an open ocean organism that lived on rafting wood, probably filtering food and serving as a refuge for other animals, such as ammonites. The crinoids had a large colonization process, based on their fossils in the wood. The large rafts were the home for a high variety of marine organisms, such as barnacles, ammonites and others. It has been estimated that without the presence of modern raft wood predators (that appeared in the Bathonian) these rafts could have lasted up to 5 years, being the main reason that the crinoids were able to reach such huge sizes. The large rafts were also probably essential to distribute animals along the Early Jurassic Seas. | Close view of one specimen from the Posidonienschiefer |

#### Sarcopterygii

| Genus | Species | Location | Material | Notes | Images |
| Trachymetopon | T. liasicum | Holzmaden Ohmden Dotternhausen | Various complete and nearly complete specimens | A large coelacanth of the family Mawsoniidae, related to the genera Axelrodichthys, Chinlea, Diplurus and the type, Mawsonia. The largest specimen known from the Sachrang Formation is GPIT.OS.770 (the holotype), being over 1.6 m long. The specimen preserves an ossified lung inside the abdominal cavity, and most of the body, being also one of the most complete coelacanths of the Jurassic found. Trachymetopon predates the earliest other presence of the family Mawsoniidae in Europe by about 120 Ma and is the northernmost occurrence of a member of the group, implying an extensive geographic range during the Early Jurassic. Due to the specimens being found on pelagic deposits, this suggests that it probably was an open ocean swimmer. | Trachymetopon GPIT.OS.770 |

| Leptopterygius? | L.? sp. | Holzmaden Ohmden Dotternhausen | Various complete and nearly complete specimens | A possible member of the family Leptonectidae. Mostly of the specimens of this genus have been referred to Leptonectes or Temnodontosaurus, although some remains on the Posidonienschiefer are too complex to being clearly referred. | |
| Magnipterygius | M.huenei | Dotternhausen | Almost complete articulated skeleton | An Ichthyosaur of the family Stenopterygiidae. Magnipterygius may not have grown to a total length of much more than 120 cm. It is therefore potentially only the second post-Triassic ichthyosaur known with such a small body size | |

A common Toarcian ichthyosaur, present in multiple layers. The rather exquisite level of preservation has led to know even the coloration, that exposes a clear countershading, with an upper part being more obscure than the lower, similar to modern killer whales, the Heaviside's dolphin or the Dall's porpoise. There is also evidence of changes in color with ontogenic changes, going from dark juveniles to countershaded adults. The skin was flexible & scaleless, as in dolphins. The study of several specimens has revelated that Stenopterygius quadriscissus underwent a size-related trophic niche shift through ontogeny, shifting from a piscivorous diet to a teuthophagous diet, known thanks to exquisitely preserved stomach contents. | Fossil |

#### Testudinata

| Genus | Species | Location | Material | Notes | Images |
| Testudinata | Indeterminate | Altdorf Banz Schandelah Hondelange | Shells? and Isolated plastrons | A marine turtle of the superfamily Eurysternidae inside Thalassochelydia. Is the main formally identified fossil as Turtle from the Sachrang Formation, representing a rather basal genus. The pleurals resemble those of the genus Plesiochelys. Being found in the zone of Franconia that on the Toarcian was at -80 km from the shore can suggest that early marine turtles lived in the epicontinental waters of the European shallow seas before reach richer ecosystem diversity on the Late Jurassic. This would explain the serious lack of Turtle fossils on the formation, as mostly of the deposits are located far from the coast. Possible unclassified testudine remains. Münster (1834) cited: "there were also rare things at the quarries of Altdorf, among other remains there were ones of a turtle on lias limestone"". The remains are not catalogued and some specimens are in Private Collections. | |

| Mystriosaurus | M. laurillardi M. sp. | Banz Altdorf Mistelgau Holzmaden Ohmden Dotternhausen Schandelah | Various complete and nearly complete specimens | A mesorostrine thalattosuchian of the family Teleosauridae. A marine crocodylomorph with a diet probably based on fish. Was considered synonymous with Steneosaurus until recently. Due to this unusual placement of the external nares, Mystriosaurus was more terrestrial, or spent a greater amount of time on land, than other teleosauroids. This would explain its greater presence in zones of the formation more proximal to the emerged landmasses. Its morphology suggest it was a mesorostrine generalist. | Mystriosaurus |
| Pelagosaurus | P. typus P. sp. | Banz Altdorf Ohmden Holzmaden Dotternhausen Dudelange-Bettembourg | Various complete and nearly complete specimens | A thalattosuchian with a complex assignation, probably the basalmost metriorhynchoid. Pelagosaurus typus was a small-bodied thalattosuchian (~1 m in length) considered to be an adept aquatic pursuit predator, with a long streamlined snout ideal for snapping at fast moving prey (one specimen was found with Leptolepis fishes inside) and large, anterolaterally placed orbits for increased visual acuity. | Pelagosaurus |

## Plantae

The macroflora of the Posidonia slate can be described as extremely poor in species. Apart from the remains of Horsetails, it is without exception the remains of coarse branches and fronds from gymnosperms, in which one has a certain can assume transport resistance. Remains of Ferns are completely missing, except for tall arboreal ferns (Peltaspermales). Mostly of the flora was reported from the area of Braunschweig. The major explanation for the flora could be that the plants in question are mono-or oligotypic stands on the edge of the waters that flow into the Posidonienschiefer sea, probably tear away in the course of flood events, easily fragmented during transport and wave waves, possibly especially in the occasional storm events postulated. In terms of taphonomy, this would result in a comparison with today's reed Phragmites, which can form extensive stocks on the edge of shallower and slowly flowing waters ("Reed belts"). The Wood remnants clearly indicate one higher diversity of Coniferous flora in the delivery area than the remains of leafy branches. This fact is likely to be proportionate, similar to that frequent occurrence of charcoalized or gagged trunks, mostly of them are believed to be "driftwoods" that only take a long time drifting also suggests a frequent settlement with mussels and full-grown Sea Lilies. The deposition settings are at large distance from the nearest coastline (for southern Germany about 100 kilometers), making only plants strong to transportation able to resist enough to get deposited. At Irlbach and Kheleim, NE of Regensburg, where the Posidonienschiefer has its near mainland deposit with abundant sand, a rich deposit filled with plant remains of different kind (Seds, Reproductive organs, Leafs, Stems, Cuticles and wood) with traces of coal was recovered, however, it was never studied in depth. Of all the plant material expected only a few Bennetites leafs and two conifer branches with leaves where cited and none studied. At the Austrian realm The sachrang Member was developed in the basinal area, while the Unken Member, sandwiched between red, often condensed limestones, represents the marginal facies. Due to be more marginal and connected with the southern Vindelician land, the most diverse palynological assemblages of the formation are found, transported from zonas with moldanuvian granites as proven by the feldspar accumulations.

### Phytoclasts

Phytoclasts have been recovered from several sections on the formation, but only studied in depth from the Dotternhausen and specially Dormettingen. Here two kinds of Phytoclasts where recovered, opaque phytoclasts (charcoal, indicator of wildfire activity on nearby landmasses, indicator of seasonal alterations of the water column) and translucent phytoclasts (indicator of proximal landmasses with high availability of wood and other plant material, as well transport conditions). On the lowermost part of the section opaque phytoclasts are low (15% of the total organic matter) while translucent are incredibly abundant (40%), lowering its abundance to a 20-10% on the next section. The Exaratum Subzone is the only one with an inverse trend and more abundance of opaque phytoclasts. On the Bifrons level, both types reach between a 15% and a 30%, showing a rapid increase, to decrease on the end of the section to values of less than 10%. Opaque Phytoclasts, for a supposed marine deposit are relatively abundant on some sections, whose decreasing on others suggest (along with increasing levels of Kaolinite) an increased delivery of land plant material by rivers, from areas with wetter climate and less frequent fires, while its rise suggest the opposite, nearby continental setting with dry climate and continuous wildfire activity.

Abundant on the Lower Jurassic of North and Southern Europe, represents pollen of medium to large arboreal plants, specially coniferales. The abundance of pollen of Classopollis and other thermophile plants was observed in this region in the lower Toarcian from the end of the antiquum (= tenuicostatum) zone to the middle of commune zone. Classopollis is correlated with evaporites and are therefore associated with desert basins, but the shrubs may have also lived in xeric upland areas with seasonal fires.

### Ginkgoales

| Genus | Species | Location | Material | Notes | Images |
| Ginkgoites | G. digitata G. sp. | Schandelah Ohmden | Leave Compressions | Affinities with Ginkgoaceae inside Ginkgoales. In the southern and northern Germany, there are regular remains of coal, which are initially reminiscent of small Ginkgo leaves. The leaves are hard to identify, more or less regularly concentric structures, as they sometimes appear like the coarse fruiting bodies of wood-dwelling fungi, such as the genus Trametes. | Ginkgoites digitata specimens |

### Pinophyta

| Genus | Species | Location | Material | Notes | Images |
