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.

[2] 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.
