    From the album Gastropods of the Tamiami Formation

    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.
  2. Echinofulgur echinatum

    From the album Gastropods of the Tamiami Formation

    Order Neogastropoda Family Echinofulguridae Echinofulgur echinatum (Dall, 1890) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC Pit Bed 4, Sarasota County, Florida USA. Status: Extinct Notes: This species is much more common in the Florida Pleistocene than the Pliocene. It lacks the row of spines on the siphonal canal which is indicative of E. helenae.
  3. Tropochasca petiti

    From the album Gastropods of the Tamiami Formation

    Order Neogastropoda Family Melongenidae Tropochasca petiti Olsson, 1967 Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA.

Status: Extant Notes: Its common name is the Ribbed Cantharus and not an uncommon find in Florida beach drift.
  13. Gemophos floridensis

    From the album Gastropods of the Tamiami Formation

    Order Neogastropoda Family Pisaniidae Gemophos floridensis (Tucker & Wilson, 1932) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: Quality Aggregates, Sarasota County, Florida USA. Status: Extinct Notes: With distinctive notch at top of the aperature but, higher and less heavy than G. tridentatus.
  14. Gemophos tridentatus

    From the album Gastropods of the Tamiami Formation

    Order Neogastropoda Family Pisaniidae Gemophos tridentatus (Tuomey & Holmes, 1856) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA. Status: Extinct Notes: Squat and Heavy with a distinctive notch at the top of the aperture lip. Also found in the Duplin Formation of the Carolinas.
  15. Solenoisteira mulepenensis

    From the album Gastropods of the Tamiami Formation

    Order Neogastropoda Family Pisaniidae Solenoisteira mulepenensis Petuch, 1994 Statigraphy: Golden Gate Member of the Tamiami Formation Location: Excavation spoil, Collier County, Florida USA. Status: Extinct Notes: Similar in form to S. vaughni but with more numerous ribbing. Appears to be endemic to the coral reef facies of the Tamiami.
  16. Solenoisteira vaughani

    From the album Gastropods of the Tamiami Formation

    Order Neogastropoda Family Pisaniidae Solenoisteira vaughani Dall, 1903 Statigraphy: Pinecrest Bed 4 of the Tamiami Formation Location: APAC Pit, Sarasota County, Florida USA. Status: Extinct Notes: Heavy and squat with lower spire and more numerous ribs than S. aclinensis.

  18. Turbo floridensis

    From the album Gastropods of the Tamiami Formation

    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.
  19. Turbo cf. dominicensis

    From the album Gastropods of the Tamiami Formation

    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.
  20. Turbo sp.

    From the album Gastropods of the Tamiami Formation

    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.
  21. Vokesinotus lamellosus

    From the album Gastropods of the Tamiami Formation

    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.
  22. Vokesinotus lepidotus

    From the album Gastropods of the Tamiami Formation

    Order Neogastropoda Family Muricidae Vokesinotus lepidotus (Dall, 1890) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA. Status: Extinct Notes: Similar to V. perrugata except ribs flare out forming winged varices.
