Delocrinus
''Delocrinus'' is a genus of Extinction, extinct crinoids, belonging to the family Catacrinidae. Specimens have been found in Kansas, Missouri, Nebraska, Nevada, Oklahoma, Arizona, Iowa, Texas, Utah and Virginia. ''Eperisocrinus missouriensis'', formerly ''delocrinus missouriensis'', was made the state fossil of Missouri in 1989. Description Like Extant taxon, extant crinoids, ''Delocrinus'' species was anchored to a hard surface by a holdfast (biology), holdfast out of which grew an articulated stalk. On top of this was a Calyx (anatomy), calyx with a number of feather-like arms. Each arm bore short branches known as pinnules and from these Cirrus (biology), cirri were extended which sifted plankton from the water flowing past. References
