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.

Old name: Protospongia rhenana Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 25:"The large sponge has the outline of a vase, flask or bowl. It has mainly bundled diactines of the first order, which are woven into a rectangular mesh, but in contrary to Retifungus are not coiled (fibre optics network). In addition, the sponge has a lot of small triaxones of the second order lying in one plane, which radiate hexagonal (so called hexatines) or possibly also tetra radial (stauracts), because of the reduction of one of the axes of a triaxon."
