Order Neogastropoda Family Buccinidae Laeviscyon planulatum (Dall, 1890) Stratigraphy: Bed 4 Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA. Status: Extinct Notes: Almost identical to L. laevis but lacking a subsutural sulcus. Since both L. planulatum and L laevis are found in the same unit, the sulculus could be variation thus making L. laevis a synonym to L. planulatum. -

Order Neogastropoda Family Echinofulguridae Echinofulgur helenae (Olsson, 1967) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC Pit Bed 4, Sarasota County, Florida USA. Status: Extinct Notes: More variable that E. echinatum, E. helenae is the common Echinofulgur in the lower beds of the Pinecrest. Ranges from tall straight individuals similar to E. echinatum to short stubby forms reminiscent of Tropochasca petiti. A row of spines on the siphonal canal distinguishes it from E. echinatum. -
