Delocrinus is a genus of extinct crinoids, belonging to the family Catacrinidae.[1] 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.[2]
Description
Like extant crinoids, Delocrinus species was anchored to a hard surface by a holdfast out of which grew an articulated stalk. On top of this was a calyx with a number of feather-like arms. Each arm bore short branches known as pinnules and from these cirri were extended which sifted plankton from the water flowing past.[3]
