Preserved from the ventral side. Taxonomy from Yochelson et al. 1983. Description from Südkamp 2017, p. 28:" The umbrella is disc-like or circular. The numerous tentacular appendages on the ventral side vary in lenght (and presumably function) and some appear to have been branched." Reconstruction from Yochelson et al. 1983, p. 40: References: Yochelson, Ellis L. & Stürmer, Wilhelm & Stanley, George D. (1983).

Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 118: " The cup is small and the crown elongate ovoid,. The uniserial robust arms divide after the third primibrach isotomously. In total, there are at least three bifurcations. The amount of brachials between the higher divisions increases. The round arms rejuvenate especially after the third division and form long, thin whip-like terminations. As in Codiacrinus these terminations are often enrolled. The upper round stem is wide and consists of low elements. The distal stem consists of alternate high elements. Many specimens have medially and distally long cirri, which rise on both sides and can divide more times." Identified by oilshale. References: Follmann, O. (1887) Unterdevonische Crinoidea.

Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 147:" The small holothurian has a cylindrical form consisting of a distinct oral region with surrounding tentacles, and at the other end an elongate body that is rounded distally. The lobate arrangement of the 25 plated tentacles, the large ovate madreporite plate (perforated plate for entering of water), and the weakly developed calcareous ring are primitive features among the holothurians. The ossicles of the body wall are numerous small granules underlain by small plate-like elements. In the basal part thorn-like elements are more abundant." Identified by oilshale using Südkamp 2017.

Taxonomy from Fossilworks.com Brauckmann et al. 2002, p. 215 claim that "Nahecaris is a subjective junior synonym of Dilophaspis as already suggested by HAHN (1990)." Description from Südkamp 2017, p. 83: "Nahecaris is the most common non-trilobite arthropod. The large bivalved shield (carapace) covers the head, thorax, and anterior segments of the abdomen. Dorsally, a short anterior rostral plate and a longer posterior median plate separate the valves. The carapace shape (deep and rounded or long and narrow) and the ornamentation (generally fine ridges parallel to the oral border) varies. A strengthened rim along the margin forms a doublure. The head bears a pair of large, club-shaped, stalked eyes, and two pairs of biramous antennae, the second much larger than the first. The thoracic segments each bear a pair of biramous slender limbs (thoracopods) that decrease in size posteriorly. Mostly, the endopods are curved downwards so that they form a cone-shaped feeding basket. The abdomen consists of seven cylindrical segments, of which only up to four are visible. The first five bear biramous limbs (pleopods) made up of flap-like branches. The seventh abdominal segment is twice to three times longer than the others. The abdomen terminates with a median telson spine, flanked by two much longer, and coarser, lateral furcal branches. The ornament of abdomen and telson is similar to that of the carapace."

Synonyms of Urasterella asperula are Protasteracanthion primus and Roemeraster asperula. Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 127: "Urasterella is the most common asteroid in the Hunsrück Slate. The small disc is composed of a hexagonal central plate surrounded by five hexagonal radial plates, and a further ring of small plates. The small mouth is built of only triangular flat plates. The dorsal surface of the round narrow arms is composed of at least three rows of plates (radials, adradials and inferomarginals; the last were pushed upwards). All plates of the dorsal side bear paxillae with spines. The plates of the oral surface are arranged in two double-sided rows (ambulacrals ans adambulacrals). Mostly, only the large disc-shaped adambulacrals can be recognized, as the opposing subrectangular ambulacrals can only be seen by the wide-opened arm furrow. The adambulacrals bear a transverse ridge carrying long spines." Name derivation: Ur = old, Aster = star. Identified by oilshale. References: Roemer, C. F.

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.

Chotecops is the most abundant trilobite in the Hunsrück Slate and due to the excellent preservation, often soft tissue such as antennae and legs have been preserved as a thin sheet of pyrite.

Taxonomy from Mindat.org. Together with the small brittlestar Ophiurina lymani. Description for the genus from Südkamp 2017, p. 106" The uniseral arms branch at least once above the second brachial. Proximally they bear pinnules on every second brachial. Beyond the seventh of these, a pinnule is attached to every brachial. Hapalocrinus has quadrangular or rectangular brachials. The anal tube is absent or incipient. The stem is slender. Some elements of the upper stem bear straight spines." Identified by oilshale. References: C. Bartels, M. Poschmann, T. Schindler & M.

Taxonomy from Ruta and Bartels 1998. Description (Südkamp 2017, p. 98): "The theca is roughly rectangular. The lateral margins are slightly arcuate longitudinally. The dorsal surface is composed of 11 marginal and two central plates; the oral surface consists of 20 plates, which are arranged in five transverse rows. The plates are thick. The sculpture of both surfaces close to the aulacophore consists of widely spaced, wavy ridges. One margin is entirely occupied by the insertion of the aulacophore; at the opposite roughly strait margin one spine articulates per corner. The elongate aulacophore tapers rapidly at the body margin and bears long spines. In most cases the aulacophore is curved over the theca. Identified by oilshale. References: IMRAN A.
