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.

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."

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.

Taxonomy according to Fossilworks.org. Characteristics of the genus according to Südkamp 2017, p. 110: “The cup is cone-shaped. The arms are very long, unbranched and without pinnules. They consist of elongate elements. The anal sac is arm-like. The round stem consists of low elements proximally.” T. elongatus is characterized by arms that can be more than 20 times the height of the cup. Identified by oilshale using Südkamp 2017.

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 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.
