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.

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.

Regulaecystis pleurocystoides DEHM, 1932 Early Devonian Emsian Kaub Formation Bundenbach Germany Length 8cm /3" -
Taxonomy from Fossilworks.org. Description (Südkamp 2017, p. 100): "The flattened theca is angular and trapezoidal in outline. The large angular anal field is positioned in the centre of one side of the theca (the anal), allowing it to be distinguished from the other (the abanal). The delicate plates are organized in large arcs across the abanal side. The peripheral rim is flat. The stem is very long. The body-oriented part consists of alternating simple and large collar ring-like elements. The more elongate distal elements are barrel-shaped. The long and slender uniserial brachiales are in the exothecal projections for food-gathering. Name meaning: Regula = Leiste, pleuro = to the side, lateral. Identified by oilshale.

Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 132: " Medusaster is a small ophiuroid with generally 11 to 15 arms. They are slender, taper in the distal part and end in blunt extremities. The disc has the same size as the mouth frame, which included the robust mouth-angle plates together with the large triangular second ambulacrals. The ambulacrals are fused into half vertebrae which are mostly aligned with their opposites. The laterals are sickle-shaped and bear some slender spines." Identified by oilshale.

Could be either B. scutatus Lehmann, 1957, B. tuberatus Lehmann, 1957 or B. devonicus, Spencer, 1927. Taxonomy from Fossilworks.org. Description by Südkamp 2017, p.125: "Baliactis has on the lowersurface the large oval madreporite at the edge of the disc. The mouth-angle plates are long and rather narrow. The evenly tapering arms consist on the dorsal surface of three series of plates (radials, adradials and marginals). At the base of the arms there is a pair of larger adradials that is continued by further adradials in a long series up to the tips of the arms. Besides them run a series of elongate marginals. The robust plates on the dorsal surface carry coarse pustules (name). The ambulacrals on the oral surface are in direct opposition and T-shaped. The adambulacrals are rather narrow, crescent-shaped, and bear small spines." Name meaning: Balios = dappled. References: W.M.

A common coral in Bundenbach. Taxonomy from Fossilworks.com Description from Südkamp 2017, p. 32:"The rugose corals assigned as Zaphrentis are also called horn corals after their familiar form. The transversely round chalk section of the polyp is divided by numerous, radiating septa sticking out interiorly. The calyx is deep." Identified by oilshale. References: Südkamp, W. (2017) Life in the Devonian. Identification book Hunsrück Slate fossils. Verlag Dr. Friedrich Pfeil, München.

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."

Loriolaster was a slow-moving low-level epifaunal detritivore-suspension feeder. Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 132: " Loriolaster is related to Cheiropteraster and differs by the following features. The smooth skin forms a wide U-shaped area between the arms. The mouth frame consists of the mouth angle plates together with only the enlarged second ambulacrals. Loriolaster has wide ambulacrals and spoon like laterals. Their margin bears three rather short spines as well as one larger spine." Loriolaster gracilis is somewhat rarer than the more robust L. mirabilis. Identified by oilshale. References: W.M.

Taxonomy from Mindat.org. 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." Hapalocrinus elegans has only ten slender free arms and no spines.

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.
