The Emergency Spillway of Caesar Creek Reservoir (Warren County, Ohio) exposes 21.3 m of the middle Bull Fork Formation (Peck 1966). Eight echinoderm genera from 2 classes have been recovered from this section including the crinoids Cincinnaticrinus pentagonus, Cupulocrinus polydactylus, Dendrocrinus casei, Dendrocrinus sp., Gaurocrinus nealli, Lichenocrinus sp. and Xenocrinus sp. and the stelleroids Kenothecaster sp. and (?) Petraster sp. Stratigraphic position and notes on the depositional environment are given for each echinoderm occurrence.
