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 sea fauna, listed below.^[1] Composed mostly by 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.^[1] Some of the preserved material has been transformed into fossil hydrocarbon Jet, specially wood remains, used for jewelry.^[2] The exceptional preservation seen on the Posidonia Shale has been studied since the late 1800s, finding that a cocktail of chemical and environmental factors let to such an impressive conservation of the marine fauna.^[2] The most common theory is the changes in the oxygen level, where the different anoxic events of the Toarcian left oxygen-depleted bottom waters, with the biota dying and falling to the bottom without any predator able to eat the dead bodies.^[3]

18x6 m fossilized floating wood (Agathoxylon), with Crinoids attached (Pentacrinites & Seirocrinus). It is one of the most emblematic fossils of the formation, where the anoxic seas of the lower toarcian lead to an exquisite preservation.

Biological interactions

• Several animal behaviours have been recovered on the Posidonia Shale. The Monotis-Dactylioceras bed is one of them, as it 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.^[4] This assemblage has been compared with modern Brazilian coastal Mangroves and also linked to Tsunami events.^[5]
• Related to the Ammonite fauna, on Holzmaden there have been found several empty shells of this cephalopods, with associated crustaceans inside.^[6] The original specimen was reported in 1995 and consisted on a possible member of the genus Paleastacus inside a chamber of a Harpoceras.^[6] Other epizoans are found related to the decayed Ammonite shells, such as Serpulid Annelids and Bivalves, creating what was denominated as "benthic islands" as reference at be isolated benthic units that attracted fauna.^[6] The Decapod is related to the family Erymidae, that are considered as possible bottom-dweller carnivorous or carrion feeders.^[6] The associated fossil has several spherical structures that had been interpreted as decapod coprolites, implying that the animal lived for a long period on the shell, and maybe changes on the bottom oxygen stopped the process.^[6] More recent studies had recovered new data about the inquilinism of decapods inside ammonites, this time, however, recovering three Eryonoidea lobsters together within a body chamber.^[7] The lobsters most likely used the ammonoid as some kind of shelter, where was excluded the possibility of transportation into the body chamber by bottom currents.^[7] There are several theories about the gregarious inquilinism showed by this specimens, such as that the shell was and ideal location to molt, as has not been proved to be corpses or molts; that the shell provided protection against predators; the decomposing soft body of the ammonoid was a source of food that attracted the decapods or that was used as a long-term shelter.^[7] One key aspect found was that the muddy bottom was not suitable for burrowing, implying that the decapods look for a different shelter due to being unable to make their own.^[7]
• 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.).^[8]

Fossil of Clarkeiteuthis preying on Leptolepis

• The genus Clarkeiteuthis and its predatory behaviour, found associated with fishes of the genus Leptolepis.^[9] Based on the position of prey and predator, was suggested that the coeloid cephalopods caught and killed the fishes while the schools still in well-oxygenated waters and then descended into oxygen-depleted water layers where the cephalopod suffocated and died attached to its prey.^[9] The fish measured 12 centimetres (4.7 in), while the coeloid 21 and it was measured by the fossilized arms of 14 specimens of coeloids that the hunting specimens arms where contracted over the fish, probably quickly killing it by cutting its spine.^[9]
• Several Geotheutis have been reported with eumelanin preserved along with its ink sacs.^[10]
• A specimen of Jeletzkyteuthis found on Ohmden has appeared predating a Parabelopeltis. The association of this 2 genera shows the predatory behaviour of this group when lived on Epicontinental seas, being rather different than extant Vampyromorphs.^[11]
• A Pabulite (fossilized meal when it never entered the digestive tract) was recovered on Holzmaden, being composed by an associated Passaloteuthis laevigata with its arms embracing an exuvia of a crustacean.^[12] The own Belemnnite can be the remnant of a failed prey of a Hybodus, corroborating a possible tropic chain.^[12]

Seirocrinus subsingularis stems over a branch

• One of the most complex organism interactions on the Posidonia Shale where the crinoid megarafts, that group a wide variety of animals, creating large floating ecosystems, being the longest surviving communities to exist in the fossil record.^[13] The largest megaraft found measured 18 metres (59 ft), and is based on an Agathoxylon trunk, where different animals were attached.^[13] The first attached animals would have been the growing community of oysters, bivalves and crinoids, that would suppose and small weight to the raft about 800 kilograms (1,800 lb).^[13] The presence of this megaraft was in part possible due to the absence of marine wood worms, that destroy tree logs on less than 3 years along without the presence of modern raft wood predators (that appeared on the Bathonian) those rafts can last up to 5 years, being that the main reason the crinoids attached were able to reach huge sizes.^[13] Probably where also essential to distribute animals along the sea basins.^[13] Seirocrinus & Pentacrinites where various of the main crinoid colonizers of the floating rafts.^[14] Seirocrinus is the main representative of the pelagic crinoids, being among the tallest animals know, with a size of 26 m the largest documented specimen.^[14] The ecology of the genus is widely known, where is 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.^[14] It is believed that Seridocrinus had a seasonal reproduction, linked to the monsoonal conditions that sent new logs to the sea.^[14] The large crinoids would have feed on pelagic micronutrients, and afer fall on the bottom, all the colony would have died.^[14]
• Thoracic cirripedes of the genus Toarcolepas became the oldest epiplanktonic cirripede known on the fossil record, probably motivated by the appearance of the giant crinoid rafts. It has been found in situ associated with fossil wood.^[15]

Hybodus hauffianus with skin and Belemnnite traces

• The shark Hybodus includes specimens with the gastric contents, being full of belemnnite fragments.^[16] That implied active predatory behaviour by the genus of several kinds of belemnnites, such as Youngibelus.^[16]
• A Spienballen, a regurgitated mass composed of indigestible stomach contents had been found on the Holzmaden quarry.^[17] The Speinballen measures 285 mm length with a diameter of 160 mm, and consists of 4 members of the genus Dapedium (Dapediidae) and a jaw identified as Lepidotes (Semionotidae).^[17] The animals capable of it had been suggested as sharks like Hybodus, actinopterygians and several marine reptiles.^[17] Hybodus, being was able to reach nearly 3 meters long and with a dentition suitable to hunt fish, although its stomach contents suggest it is a mostly invertebrate hunter.^[17] Actinopterygians like Saurostomus grew up to 2 m long, and have been found with fishes, coeloids and ammonites in its stomach contents, however, not the fishes present on this Spienballen.^[17] Marine reptiles included marine crocodiles, such as Platysuchus or Pelagosaurus, associated to the fishes of the Speinballen, although are proven to have eaten gastroliths to improve buoyancy and digestion.^[17] Ichthyosaurs, whose diet is among the best studied of the Posidonia Shale, with Dapedium specimens in juvenile stomachs, along with coeloids. Temnodontosaurus, measuring between 8 and 13 metres (26 and 43 ft), would have been able to do such a large Speinballen.^[17] Plesiosaurs were disaccredited due to the study of its teeth, that proves a diet based on soft-body prey, such as fishes of the genus Leptolepis and coeloids. Dapedium and Lepidotes, with a heavy and solid squamation can be excluded.^[17]
• A specimen of Pachycormus has been found with stomach contents that include hooks similar to the ones found on genera like Clarkeiteuthis.^[18]
• Another specimen of Pachycormus macropterus preserves an ammonite inside its gut, likely swallowed by accident and directly responsible for the fish’s death.^[19]
• SMNS 51144 (Saurostomus esocinus) was found with Chondrites isp. burrows in the abdominal cavity, what indicates a possible opportunistic scavenger. Other Chondrites isp. includes SMNS 17500 and MHH 1981/25 (Stenopterygius uniter) that can either suggest ichthyosaurs were preserved immediately below one such bioturbation horizon or scavenger association.^[8]

Stenopterygius quadriscissus, mother with embryo

• The know specimens of Toarcocephalus are evidence of successful predation events, as the head of one was isolated likely as product of a decapitation and other preserved within a regurgitated mass.^[20]
• One of the most emblematic finds of the formation its that of a mother Stenopterygius giving birth living young, like the modern dolphins and marine mammals, being born with the tails first. Other specimens have been found with Embryos inside, but with the bones of them scattered, partly beyond the body limits of the mother.^[21] There have been various theories about this scenario: the bones of embryos had been deposited before the body of the adult went to the sea floor, covering the embryo bones and implying that the adult would not be the mother of the embryos.^[21] Another option is that a pregnant ichthyosaur on its last moments sank to the bottom and may have struggled for life, given untimely birth to some of the foetuses.^[21] Other option follows the presence of foetus bones outside the mother body, where a dead female sank to the bottom, with the water warm enough, helping the putrefaction gases to start to develop while the hydrostatic pressure was too high to be prevented by the body. Scavengers must have started eating from the dead body, until the chamber retaining the pressure was to thin and exploded.^[21] These theories where however contested after the study, where it was criticised the absence of the presence of the bottom-current activity in the epicontinental sea covering Central Europe during the Toarcian, pointing that the mother carcass should have been translated after it sank to the bottom floor, probably exploding or expelling its embryos first, that would be transported along.^[22]
• 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.^[8]
• SMNS 80234 (Stenopterygius quadriscissus) represents another female with embryos, yet also shows ribs broken perimortem that can be either of intraspecific aggression or a predation attempt. This specimen has several taxa associated: ammonite aptychi and two ophiuroids (Sinosura brodiei) and a articulated echinoid (Diademopsis crinifera), indicating a short-lived deadfall community.^[8]
• SMNS 81841 (Stenopterygius quadriscissus) represents one of the most clear 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.^[23] As many of this bivalves shown overgrowth likely the community persisted for some time.^[23] Fossil traces of Gastrochaenolites isp. attributed to mechanical bivalve borers are abundant implicating prolonged exposure of the skeleton on the seafloor.^[23]
• 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 stratigraphically below the specimen.^[8] This specimen includes also traces of scavenging activity, possibly by crustaceans.^[8]
• 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.^[8]
• 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.^[24]
• Gut contents of the local pterosaurs are know: Campylognathoides preserves hooks of the coeloid Clarkeiteuthis being the one of the few teuthophaous pterosaursy, while Dorygnathus preserves remains of Leptolepis.^[25]

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.^[26] 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.^[26] There is a thin, southern widespread Stromatolite crust on the Top of the Sachrang Formation, called "Wittelshofener Bank", that has made rethink the depth of the major southern basin of the formation, where with the absence of phototrophic calcareous benthic organisms (probably due to the lack of light), shows the depth character of the basin.^[26] On the "Wittelshofener Bank" there is also the only occurrence of Ooids, presumably formed in the same deep-water environment.^[26]

The only difference compared to the Paleozoic forms is the much thinner cellular wall of the specimens described, which otherwise seems to be always thicker, and the more irregular shape of the individual tubes. Girvanella is almost rock-forming in the Lower and Upper levels, and is very common, but can only rarely be detected in the bituminous clay marl slate due to conservation reasons.[27] The Girvanella specimens recovered on the Posidonienschiefer can come from Diatomeas rather than Cyanobacteria, but its assignation is rather controversial.[27]

Dinoflagellata

Dinoflagellate cysts

The evolutionary burst of the Toarcian Dinoflajellates led the first appearance and rapid radiation of the Phallocystaceae (Susainium, Parvocysta, Phallocysta, Moesiodinium and related forms).^[30] This occurred at the time of a widespread Lower Toarcian bituminous anoxia-derived shale of the Posidonienschiefer Formation. Is recovered on 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.^[30]

Ichnofossils

The major ichnological analyses of the Posidonian Shale come from Dotternhausen/Dormettingen, where the ichnogenus Phymatoderma formed the so-called Tafelfleins and Seegrasschiefer.^[48] The Tafelflein bed was deposited under anoxic bottom and pore water, where a recover of oxygen allow the Phymatoderma-producers return.^[48] 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.^[48] The Coeval more nearshore Swiss deposits referred Posidonian Shale (Rietheim Member) hosted similar trace fossils asthose recovered on SW Germany.^[48] Tougth this setting apparently evolved faster to more oxic-to-dysoxic bottom waters.^[48] At Unken, laminated deposits of red limestone suggest well oxygenated active waters (as lack shale), where high amounts of Chondrites are found.^[40]

Interpreted as the feeding burrow of a sediment-ingesting animal.[51] A more recent study has find that Scoloplos armiger and Heteromastus filiformis, occurring in the German Wadden Sea in the lower parts of tidal flats, make burrows that are homonymous with numerous trace fossils of the ichnogenus.[52] Chondrites burrows from Holzmaden are mostly filled with granular Calcite crystals, clay minerals, and rare framboidal Pyrite. The local dysoxic seawater is reflected on the palaeoredox conditions, relating framboidal pyrite and biogenic processes. Chondrites appear to be capable of colonizing environments characterized by oxygen levels well below levels needed for survival of other animals, being considered an "extremotolerant" ichnotaxon.[53]	Illustration of Chondrites bollensis

Phymatoderma[56]	P. granulata	Dotternhausen Holzmaden	Burrowing and track ichnofossils.	Burrow-like ichnofossils. It consists commonly on a subhorizontal branching burrow system consisting of radiating tunnels filled with fecal pellets.[56] It has been interpreted as a product made by an Endobenthic deposit-feeding animal, specially a Fodinichnia, burrows produced by benthonic subsurface food-mining activity, as is proved by the tunnels and pelletal infill.[56] The study of the Fecal Pellets has revelated that the maker of this ichnogenus was an epicontinental shelf setting non-selective deposit feeder, ingesting particles on the sediment surface without selection. A mode of feeding common on aquatic Benthos, reported on modern animals such as Spionid Polychaete worms, tropical Holothurians and Spatangoid urchins.[57]

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.^[27] They are usually associated with radiolarian stone cores. In Dusslingen and Reutlingen, these sponge needles could be 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.^[27] 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.^[40] 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.^[40]

Bositra[63]	B. buchii B. radiata	All the Formation	20.000 specimens/m2	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 was 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,[64] a benthic organism related to open marine floor, where it was the main inhabitant of the basinal settings, and a hybrid mode, where it has a life cycle with holopelagic reproduction controlled by the change on Oxygen levels, and even a chemosymbiotic lifestile, related to the large crinoid rafts, being the main "Safe conduct" to evade anoxic events. All the opinions along the years led to a large study in 1998, where the size/frequency distribution, the density of growth thanks to the lines related to the shell size and the position of the redox boundary by total organic carbon diagrams has revealed that Bositra probably had a benthic mode of life.[65]	Thousands of specimens in one matrix

The second largest Decapodan from the formation, P. giganteus is a species reaching a larger size than most other polychelidans, with up to 15 cm. On the Sachrang Formation there is the most abundant variety of species from the genus, ranging from different sizes and morphologies, that indicate different habitat & feeding adaptations on the genus. Some like P. hartmani show less adaptations to hunt for small nectobenthic preys than other relatives, being abundant on Oyster-filled waters. There is a relatively abundance of the genus in deep-water settings from the Toarcian onward.[126]	Proeryon giganteus

Due to that and the disposition of the specimens probably represent a mass-mortality assemblage and suggest this species was gregarious.[116]

Echinodermata

Echinoderm debris is pretty abundant on the shale-free Unken and Salzburg members, including Crinoid skeleton elements, also that of the Ophiurida; the Echinoids take their place, where really blossomed at that time. That's why Pedicellaria are observed very often.^[40]

Among the tallest animals of its period, Seirocrinus is also one of the most famous fossils from the Sachrang Formation. It consists of fossils of colonies along large wood trunks, with specimens up to 14 m long, with the largest specimen reaching 26 m long, what makes it among the tallest know Mesozoic organisms, one of the largest invertebrates know on the fossil record and one of the tallest know animals.[174] It was an open ocean organism that lived in rafting woods, probably filtering food and serving as a refuge for other animals, such as ammonites. The crinoids had a large colonization process, based on the status of the fossil wood found.[175] The large rafts were the home for a high variety of marine organisms, such as Balanoideans, Ammonites and other. It has been estimated that without the presence of modern raft wood predators (that appeared on the Bathonian) those rafts can last up to 5 years, being that the main reason the crinoids were able to reach such huge sizes. The large rafts were also probably essential to distribute animals along the Early Jurassic Seas.[13]	Close view of one specimen from the Posidonienschiefer

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.[222] 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.[223]	Fossil

This gastroliths have importance for its exotic provenance compared with the surrounding lithology of the deposits (mostly shale), and as sandy turbidites have never been reported from the SW German Basin, the individual may have acquired the sand-sized grains many kilometres away from the burial site.[231] Strata containing fine sand ('Glaukonit und viel Feinsand') at Obereggenen im Breisgau (western side of the Black Forest between Freiburg and Basel), 200 km from Holzmaden suggest a nearshore deposit was allocated here, and that the black forest emerged at this time. Probably this young specimen reached that location in search for gastroliths.[231]

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.[239] 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.[239] This would explain the serious lack of Turtle fossils on the formation, as mostly of the deposits are located far from the coast.[239] 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.[243]

The pelvis indicates a laterally, slightly upwardly directed orientation of the acetabula which does not support a bird-like bipedal locomotion of this pterosaur as has been suggested on the past.[94]

Plantae

The Flora is dominated by horsetails, what can be due to a similar ecological niche to modern genus Phragmites, able to resist saline conditions. Storms or floods maybe where the major events that transported this flora to the sea.

The macroflora of the Posidonia slate can be described as extremely poor in species.^[258] 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).^[259] Mostly of the flora was reported from the area of Braunschweig.^[258] 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.^[260] 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").^[258] The Wood remnants clearly indicate one higher diversity of Coniferous flora in the delivery area than the remains of leafy branches.^[258] 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.^[258][260] 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.^[261][145] 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.^[83] Of all the plant material expected only a few Bennetites leafs and two conifer branches with leaves where cited and none studied.^[83] 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.^[40] 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.^[40]

Phytoclasts

Phytoclasts have been recovered from several sections on the formation, but only studied in depth from the Dotternhausen and specially Dormettingen.^[46] 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).^[46] 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.^[46] 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%.^[46] 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.^[46]

Widdringtonites[258][277]	W. liasicus	Holzmaden Ohmden Irlbach	Fragmentary axis compressions with preserved leaves	A possible ancestral member of the Callitroideae inside Cupressaceae, or a member of Cheirolepidiaceae. Named also "Cupressites" liasinus, represents probably Arbustive to arboreal-derived axis.	Widdringtonites liasinus specimen from the Sachrang Formation

Fossil wood

Fossil Wood increases on the marginal Unken Member, with great amounts of logs and fragments of more than 1 m. Surface studies suggest relationships with the wood genera identified on the coeval Úrkút Manganese Ore Formation.^[278]

Genus	Species	Location	Material	Notes	Images
Agathoxylon[14]	cf. A. sp.	Dotternhausen Ohmden Holzmaden	Fossil wood	Affinities with Araucariaceae inside Pinales. Has araucarioid structures, but lacks proper characters of extant genera such as Araucaria & Agathis The largest known rafting wood on the fossil record is assigned to this genus, with a length of 18 m. The rafts were populated with Crinoid colonies, and a wide variety of organisms.[14]	Araucarioxylon (=Agathoxylon) reconstruction
Araucariopytis[47]	A. nicri A. tubingense A. sp.	Dotternhausen Ohmden Holzmaden	Fossil wood	Affinities with Abietinae inside Pinales. This genus was found to be related with Protocedroxylon found on the coeval Whitby Mudstone, crucial to the interpretation of the fossil record of Early Abietinae.	Abies specimen, whose role was probably covered by the makers of the Araucariopytis woods.
Circoporoxylon[258][279][280]	C. grandiporosum	Braunschweig area GroßGschaidt near Erlangen	Fossil wood	Affinities with Podocarpaceae inside Pinales. Acmopyle pancheri is the only living conifer that has real resemblance with the wood assigned to Circoporoxylon. Xenoxylon phyllocladoides and C. grandiporosum are commonly found associated, for example in Braunschweig area.
Cupressinoxylon[258][259]	C. sp.	Reutlingen Holzmaden Ohmden Dotternhausen	Fossil wood	Affinities with Cupressaceae inside Pinales. Wood with a morphology similar to the modern genus Metasequoia. Probably related to Widdringtonites liasinus.	Metasequoia specimen, whose role was probably covered by the makers of the Cupressinoxylon woods.
Podocarpoxylon[258][259]	P. sp. cf. P. sp.	"Georg-Friedrich" mine not far from Liebenberg near Grauhof in the Harz foreland Wenzen between Einbeck and Alfeld Mistelgau Altdorf	Fossil Wood	Affinities with Podocarpaceae inside Pinales. resembling modern genera such as Dacrycarpus, with other specimens resembling Juniperus. Includes wood more related to nearshore arbustive Conifers (columnar or low-spreading Shrubs with long, trailing branches), being the most abundant, but also medium to large arboreal conifers from nearshore forests.	Podocarpoxylon specimen
Protocupressinoxylon[258][281]	P. catenatum P. liasinum	Mistlegau Hondelange Glasser Kerkhofen Altdorf Holzmaden Ohmden	Fossil wood	Affinities with Cheirolepidiaceae inside Pinales. Includes large sized trunks up to 1.7 m tall and 115 cm wide. Wood of other species of this genus, such as Protocupressinoxylon purbeckensis grown on flood-influenced settings of vegetated soil with brackish-water, like modern Swamp Cypress.	Protocupressinoxylon catenatum specimen
Protophyllocladoxylon[258][259]	P. quedlinburgense P. franconicum	Kerkhofen Altdorf Meilenhofen Dörlbach	Fossil wood	Affinities with Podocarpaceae and Cupressaceae inside Pinales. The assignation of this genus is rather complex.	Bivalves added to a Protophyllocladoxylon driftwood
"Protopinaceae"[258][282]	P. sp.	Hondelange Beienrode Schandelah Holzmaden Ohmden Dotternhausen	Fossil wood	Wood of the Protopinaceae, a possible "morpho-group" of the family Cheirolepidiaceae. Belongs to an invalid group of mostly Paleozoic Woods, and all the woods assigned to the family should be treated as Incertae Sedis.[283]	Woodworthia, example of Protopinaceae
Phyllocladoxylon[258][259]	P. sp.	Hondelange Hattorf Holzmaden Ohmden Altdorf	Fossil wood	Affinities with Podocarpaceae inside Pinales. Phyllocladus is the extant genus of conifer whose wood is more similar.	Phyllocladus specimen, whose role was probably covered by the makers of the Phyllocladoxylon woods.
Taxodioxylon[258][284]	cf. T. sp.	Altdorf Korbach Hondelange Holzmaden Ohmden Dotternhausen	Fossil wood	Affinities with the Cupressaceae inside Pinales. Probably related to the coastal settings. It maybe covered a similar role that modern Swamp Cypress, Taxodium distichum.	Taxodium distichum specimen, whose role was probably covered by the makers of the Taxodioxylon woods.
Xenoxylon[258][280][285]	X. phyllocladoides X. cf. barberi X. ellipticum	Braunschweig area Taught near Hanover Dörnten not far from Liebenburg, district of Goslar	Fossil wood	Affinities with Coniferales, concretely is closer to the Podocarpaceae, Cupressaceae and in a lesser extend to the Cheirolepidiaceae. Finally can be a member of the extinct family Miroviaceae. It is the more abundant genus of wood present on the Bohemian Realm of the Sachrang Formation.
