Order Trocida Family Turbinidae Turbo floridensis Olsson & Harbinson, 1953 Statigraphy: Golden Gate Member of the Tamiami Formation Location: Spoil, Collier County, Florida USA. Status: Extinct Notes: Similar in appearance to recent Turbo castanea which has alternating rows of major and minor noded spiral cords, T. floridensis has noded cords of equal strength. Its operculum is similar in appearance to that of T. dominicensis however that of T. floridensis has a flattened shelf along the rim that does not show well on the photo. -

Order Trocida Family Turbinidae Turbo cf. dominicensis Gabb, 1873 Statigraphy: Golden Gate Member of the Tamiami Formation Location: Spoil, Collier County, Florida USA. Status: Extinct Notes: The beaded appearance of the spiral chords on this partial shell is similar although not as strongly expressed as in Woodring 1928 drawing of T. dominicensis from Bowden, Jamaica. The operculum is domed and beaded. -

Order Trocida Family Turbinidae Turbo sp. Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA. Status: Extinct Notes: Originally I had identified this species as Turbo dominicensis based upon images in popular publications and dealer sites, however it does not bear any resemblance to that species as shown in Woodring"s 1928 figure in his manuscript on the Fossil Mollusks of Bowden Jamaica. The pictured species has thin, non-noded spiral cords and compares well with undescribed specimens in the Florida Museum of Natural History UF31535. -
Before pictures are shown, I want to give @MikeR special thanks for helping to ID my finds. I spent countless hours attempting to name my specimens before showing them to Mike. So I am sure he too donated many hours of help to me. Lets say my batting average was a little under 50% (which included obvious ones that I did not send to him) in correctly IDing the shells. Hats off to my teacher!!!!! Less than 50% does mean I received a failing grade. So unfortunately for MikeR, I must repeat his course next year! With my gratitude expressed, let me get on with the topic. There was a wonderful shell bed quarried in the Sarasota, Florida area. That quarry had been abandoned years ago and the most productive piles used in the construction industry now seem to be disappearing. The specimens likely came from this quarry and are from the Tamiami Formation, likely Pinecrest Beds, a late Miocene to Pliocene formation. I have collected and reported on this formation before so many species found this winter are not shown again. These are either my favorites or new specimens for me.

Order Neogastropoda Family Muricidae Vokesinotus lamellosus (Emmons, 1858) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA. Status: Extinct Notes: Emmons (1958) first described Fusus lamellosus from the Miocene (now Pliocene) of North Carolina and Dall (1890) described Coralliophaga lepidotus from the Pliocene (now Lower Pleistocene) of Florida. Olsson & Harbinson (1953) figured Trophon lepidotus from the Caloosahatchee Formation, however Campbell (1993) listed Urosalpinx lepidotus in the Pliocene of Florida, North Carolina and Virginia overlooking lamellosus entirely. Those shells in the Caloosahatchee have a lower spire than the predominate shells in the Tamiami although some with lower spire heights can be found. For this reason I have chosen V. lamellosus as the high spired species and V. vokesinotus with the lower spire height. If both are the same, the proper name would V. lamellosus with V. lepidotus as a junior synonym by 32 years. -
