New Cladid Crinoid (Phylum Echinodermata) from the Middle Devonian Delaware Limeston, Franklin County, Ohio

Abstract

A new species of Goniocrinus, G. saettii, is described from the Delaware Limestone of Franklin County, OH. This is the first crinoid described from the Delaware Limestone and the first cladid crinoid described from Devonian limestones of Ohio. This new occurrence suggests that additional new echinoderm specimens may be found in Devonian limestones of Ohio with a directed search for strata conducive to complete echinoderm preservation, that is, rapidly deposited, fine-grained facies.
