Taxonomy from PaleobioDB.org.
Description of the genus by Südkamp 2017, p. 116: "Follicrinus is one of the largest crinoids in the Hunsrück Slate. The arms can be over 20 cm in length. The dicyclic conical cup was relatively small and as wide as high. The long, slender, uniserial arms divide three to four times isotomously and bear no armlets. The first branching occurs above the fourth or fifth primibranch. The stem is round.”
