Two New Gastropods from the Pliocene Pinecrest Beds Of Florida

Torrance C. Raymond

Abstract


New species continue to be discovered from the mollusk-rich Pliocene Pinecrest Beds near Sarasota, Florida. Two new gastropods are described herein, each of which is a large-sized member of a genus not commonly found in the fossil record. The first, a Morum, appears to be an intermediate species between the Miocene M. chipolanum and the Recent M. dennisoni.  The second, apparently a Phenacovolua, is perhaps the only representative of that genus, fossil or Recent, in the Western Atlantic. Both are known only from single specimens.
