  4. Taxonomy from Fossilworks.com. Alternative combination: Aspidosoma roemeri. Description from Südkamp, 2017, p. 134: "Encrinaster has many characteristics common with Euzonosoma. The differences are as follows. The elongated arms are strap-like, broadening distally until the disc edge and then tapering evenly as comparatively narrow arms to the arm tips. The interradial disc outline is convex to straight. The marginals are flat overlapping plates. The ambulacrals are more delicate, less rectangular than in Euzonosoma, and more sub-triangular in oral view." Identified by oilshale using Südkamp 2017. References: Schöndorf, F.

  5. I am a bit confused and have no idea about trilobites. I know these two trilobites from the Devonian (Emsian) of Bundenbach under the name 'Asteropyge' and 'Rhenops cf. anserinus'. Is it the same species? Both are unfortunately only visible from the ventral side and both pictures are exactly vertical from above. Is the second trilobite just a bit compressed or is the body shape really different? At least the name Asteropyge seems not to be valid.

  8. Taxonomy from Fossilworks.org. Description of the genus by Südkamp 2017, p. 116: "The small cup is conical. The long slender arms are unbranched or may have a single isotomous division high above the cup. So, there are 7 - 10 arms present. Between the long, stout alternating ramules there are two brachials. The anal sac is large and elongate and consists of several vertical rows of small hexagonal plates." There are two species known: R. ramosissimus and R. lobatus. The difference is respectively in their round and similar, and pentagonal alternate, stems. The cup of R. lobatus is more tapered. Common in the Rosengarten quarry. Elsewhere very rare or absent. Identified by oilshale. References: Schmidt, W. E. (1934). Die Crinoideen des Rheinischen Devons.

  9. Originally described under the name Urasterella verruculosa Lehmann 1957. Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 130: " The five, ribbon-like, flattened long arms join at the mouth frame; there is no interbrachial disc. The mouth frame is built as a ring of robust plates. The plates of the dorsal surface (radials, a primary circlet, and the large madreporite) are difficult to determine with certainty. Pedicellariae are irregularly arranged on the dorsal surface and as an organized fringe by the spacing of the adambulacrals. The pedicellariae are rounded triangular in outline. The ambulacrals are flat plates with a T-shaped ridge. Their arrangement across the arm midline is neither strictly paired nor alternate." Identified by oilshale using Südkamp 2017.

  10. Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 139: " Furcaster is a very abundant ophiuroid with opposing fused ambulacrals. These vertebrae are elongate and wing-like. The five narrow arms are high and taper to whip-like extremities. Each ambulacral pair has a pronounced median dorsal oval cleft. The ambulacral plates are essentially flat and plastron-like orally (plastron is the lower shell of a turtle). The round small disc is granulated. The mouth frame is petaloid and the mouth-angle plates are sub-triangular in outline. The ambulacral groove is open. The laterals are blocky to barette-shaped. They bear a tuft of vertical needle-like spines, and leaf-like groove spines." Lehmann (1957) listed three species: Furcaster palaeozoicus, F. decheni and F. zitteli. F. palaeozoicus is smaler and less robust than F. decheni. The disc incorporates about three arm segments. Identified by oilshale. References: Stürtz, B.

  12. Hello all, Thank you always for your help. This time I'm asking about a Bundenbach crinoid I came across. The seller says it's a Thallocrinus sp. but an unusual one and that "Bundenbach crinoid experts" are divided on further identification. More importantly, I have very little experience looking at these sort of crinoids and honestly this almost looks spray-painted gold to me (even though I know these are pyritized) so I wanted to consult TFF experts on it regarding its authenticity. The first 2 photos taken under flash photography, the rest in natural sunlight: If it is genuine, what do you think of the species ID? The following photo is the only other Bundenbach Thallocrinus I could find, a Thallocrinus procerus, but it has much clearer pinnules than the specimen in question. I cannot tell if this is due to difference in species, incomplete prep, or worst of all bad preservation, though the seller claims poor preservation is not the case here. Thank you.
  13. Taxonomy from Fossilworks.com. Description from Südkamp 2017, p 140:" Eospondylus is related to Furcaster, especially for its ambulacrals fused into vertebrae, their form, their deep median dorsal cleft and the open groove. The circular disc incorporates only two arm vertebrae and bears small scale-like plates. The five long arms are about as high as wide. They can bend extremely, up to 180° involving seven segments. The laterals have a vertical spine ridge bearing a row of long spines of unequal length. The laterals on the oral surface are more conspicuous, somewhat pear shaped and bear minute groove spines."

    Living tube of a polychaete worm

    This ichnofossil consists of an accumulation of tentaculites, probably of the genus Styliolina. Dr. M. Poschmann (General Directory of Cultural Heritage Rhineland-Palatinate in Koblenz) mentioned in a personal communication that accumulations of tentaculites / styliolites from the Hunsrück Slate are known, also in the State Collection in Mainz such pieces are found. Tentaculite accumulations can occur in quite different forms, among them those which are probably to be interpreted as coprolites due to their shape and rather irregular arrangement. Cylindrical assemblages of tentaculites / styliolines with orientation of the shells transverse to the long axis (as in this case) are also known and have been interpreted as agglutinated housing tubes of polychaetes worms. At the University of Bonn a diploma thesis on this topic has been done in 2010 - unfortunately no results have been published until today. Identified by Dr. M. Poschmann.
  15. Cheiropteraster giganteus reached diameters up to 50 cm / 20”. Taxonomy from BioLib.cz. From Südcamp 2017, p. 132: “Cheiropteraster is a very large ophiuroid with no disc, but a granulated skin reaching the tips of the five arms. The mouth is extremely large and V-shaped reaching up to the fifth ambulacral pairs. The elongated ambulacrals stand out as a topographic high and form alternating half-cylinders. Orally, they are boot-shaped. The laterals are T-shaped and bear long spines along the edge.” Identified by oilshale using Südcamp 2017. References: Stürtz, B.

  16. This rare Palaeosolaster lies somewhat unfortunate on its side and is not completely preserved. A conularia is partially hidden by the arms. Taxonomy from Fossilworks.org. Synonyms: Echinasterias Stürtz 1899, Echinodiscaster Stürtz 1899, Echinodiscites Stürtz 1899, Echinodiscus Stürtz 1899, Echinostella Stürtz 1899. From Südcamp 2017, p. 124: “Palaeosolaster is similar to Palasterina, but can be distinguished easily by its 25-29 arms and large mouth. The mouth-angle plates are narrow and show high relief. The madreporite lies on the oral surface. The groove is wide. The opposite broad flat ambulacrals have L-shaped ridges. The narrow adambulacrals, which are similar to the side-shields of ophiuroids, bound the oral margin of the arms and bear short spines. The interbrachial areas and the dorsal surface are filled with scattered plates, each bearing a spine.” Identified by oilshale using Südcamp 2017. References: Stürtz.

  17. Eriniceaster tenuispinosus Lehmann 1957 is a homotypic synonym of Erinaceaster tenuispinosus Lehmann 1957 Taxonomy from GBIF.org From Südcamp 2017, p. 127: "The disc and arms on the dorsal surface are covered with a distended, granular, spine bearing skin. The spines are elongate and needle-like. The high domed body has been transformed into a fringe around the five lancet-shaped arms by later flattening. The mouth frame is large and stellate and the mouth-angle plates are triangular. The small madreporite has an oral position. The ambulacrals are either opposite or alternating and smooth L-shaped. Together with the sickle-shaped laterals they have the outline of a low W. They bear a row of nodules each bearing an elongate slender spine. The ambulacral groove is wide."

  18. Roofing slate mining in Bundenbach (Eschenbach-Bocksberg mine) was discontinued in 1999. Taxonomy according to Fossilworks. Diagnosis in Südkamp, 2011: "The large, bowl-shaped cup is composed of three low infrabasals and two uninterrupted circlets of large, five-sided basals and radials. The angustary radial facets are horseshoe-shaped. The basals and radials have a striated surface sculpture (hexagonal concentric lines). The uniserial arms branch isotomously on primibrach three normally and heterotomously higher in the crown. The secundi- and tertibrachs have thorn-shaped plates aborally. The circular xenomorphic stem lacks a radix." Identified by oilshale. References: Follmann, O. (1887) Unterdevonische Crinoiden.

  19. Alternative names: Mitrocystites styloideus or Dalejocystis styloideus. Taxonomy from Mindat.org. Description (Südkamp 2017, p. 98): "The theca is roughly semicircular. It consists of two large thin plates on the oral surface, which nearly completely overlap the dorsal surface. The margin in the neighbourhood of the aulacophore is sometimes arcuate and bears medially the slender insertion of the aulacophore. Next to it, on the oral surface, short transverse riblets can be seen, which are directed to the aulacophore. The lateral margins of the dorsal surface bear a row of knots. The elongate aulacophore bears spines, which taper to the end. The anterior large ossicle (stylocone) has the appearance of a buttercup. At the other edge of the body a strong spine is attached, but is missing in most species." Name derivation: Stylos = pillar. Identified by oilshale. References: Dehm, R. 1934.
