Encrinaster roemeri Schoendorf, 1910 Early Devonian Emsian Kaub Formation Bundenbach Rhineland Palatinate Germany -
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.

Regulaecystis pleurocystoides DEHM, 1932 Early Devonian Emsian Kaub Formation Bundenbach Germany Length 8cm /3" -
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.

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."

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.

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.

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."

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.

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.

Description from Südkamp 2017, p. 111: " Cup very tall and narrow cylindroconical. The long, slender, non-pinnulated arms divide three to four times isotomously abouve the fourth to fith primibrach. The anal sack is narrow and elongate and composed of several vertical rows of plicate plates. The appearance of the stem is reminiscent of a string of pearls. Only the proximal part consists of short, pentagular elements." Identified by oilshale. References: Schmidt, W. E. 1934. Die Crinoideen des Rheinischen Devons.

Taxonomy from GBIF.org Description from Südcamp 2017, p. 34: "The colonies of this tubulate coral are more or less circular in outline. The lower side shows concentric growth lines that give it a wrinkled appearance. The upper side reveals the polygonal form of the corallites, which is often hexagonal. The corallites are of different sizes and the thick walls are perforated by pores. Tabulae are usually absent. This gives the colony the appearance of a series of cavities."

Together with Hapalocrinus frechi JAEKEL, 1895. Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 142: "Ophiurina and 'Eschenbachia' are the smallest ophiuroids of the Hunsrück Slate. The round disc is covered with a finely granular skin. The margin of the disc consists of 15 rod-like plates, of which every three of them are lying interradially. The marginals are connected to the second arm segment (personal information F. Hotchkiss, 2016). the vertebral halves are arranged in opposing pairs. The largest elements of the arm skeleton are the curved laterals, which bear a row of small spines of unequal length. They are orally touching across the midline of the arms. The five slender arms taper in their first halves evenly and the laterals become long slender rods towards the extremity of the arms" Identified by oilshale. References: Stürtz, B.

Euzonosoma was a brittlestar genus that existed during the Devonian period. This E. tischbeinianum is from the Bundenbach slate of Germany. The slate was quarried for use in the roofing industry for many years and, at least in some parts of Germany, you can still see houses covered by Bundenbach slates. Unfortunately, roof-slate mining in Bundenbach came to an end in 1999. The fossil has been replaced by iron pyrite or ''fool's gold''. The brittlestar already started to become decomposed at the tip of the arms. Taxonomy from Fossilworks.org. Alternative combinations: Aspidosoma tischbeinianum, Encrinaster tischbeinianus. Description from Südkamp 2017, p. 132: " The quite large disc is composed of large and irregularly polygonal plates. The disc has a concave margin and is bound by blocky rounded marginals. They have in the middle part their largest size. The mouth-angle plates are small and stumpy and have a broad proximalgroove. The five elongate arms are the broadest just outside of the disc edge, taper strongly and end whip-like. The ambulacrals alternate over the midline and are rectangular dorsally. They form transverse ridges that are groove-like and, especially within the disc, deeply sunken. Orally the ambulacrals are boot-shaped. The tall laterals are blocky, rectangular and bear short groove spines." Identified by oilshale. References: Roemer, C. F.
