Cicerocrinus is an extinct genus of crinoids in the family Pisocrinidae. It is known from the Silurian of the United Kingdom. The type locality for C. elegans is Old Bridge near Ludlow.
Crinoids are marine animals that make up the class Crinoidea, one of the classes of the phylum Echinodermata, which also includes the starfish, brittle stars, sea urchins and sea cucumbers. Those crinoids which, in their adult form, are attached to the sea bottom by a stalk are commonly called sea lilies, while the unstalked forms are called feather stars or comatulids, being members of the largest crinoid order, Comatulida.
