New fossil crinoids from Jamaica

Abstract

Fossil crinoids are poorly known from the Antillean islands. To the five taxa of fossil crinoid previously recorded from Jamaica are added two further species of isocrinid, both based on pluriocolumnals and left in open nomenclature. Austinocrinus n. sp. is the first Lower Cretaceous echinoderm to be described from Jamaica and represents the earliest report of this genus. It is the only fossil stalked crinoid from Jamaica to occur in a shallow-water deposit. Isselicrinus cubensis ? (Valette, 1926) forms part of an allochthonous assemblage in the Lower Eocene Port Maria shell bed. Isselicrinus cubensis was originally described from Cuba, and the genus also occurs in Haiti, Mexico, and elsewhere.
