Order LittorinimorphaFamily StrombidaeLobatus leidyi (Heilprin, 1886)Location: Bonita Grande Pit (Golden Gate Member), Lee County, Florida USA. Status: ExtinctNotes: A common species in the Lower Caloosahatchee Formation, it is also found in the Upper Pliocene Golden Gate Member of the Tamiami Formation. Compare to an excellently preserved specimen from the Caloosahatchee Formation. LINK -

Order LittorinimorphaFamily StrombidaeLobatus williamsi (Olsson & Petit, 1964)Location: Bonita Grande Pit (Golden Gate Member), Lee County, Florida USA. Status: ExtinctNotes: Large Strombid with a flaring aperture lip and locally abundant in the Golden Gate Member of the Tamiami Formation. Similar to pictured Lobatus cf. gigas but does not have strong development of shoulder nodes. -

Order LittorinimorphaFamily StrombidaeLobatus cf. gigas (Linneaus, 1758)Location: Imokalee (Golden Gate Member), Collier County, Florida USA. Status: ExtinctNotes: Originally identified as L. dominator. After consultation with Stromboidea experts, original identification within the Golden Gate Member was incorrect. Closest resemblance is to the extant Queen Conch, Lobatus gigas. -

Order LittorinimorphaFamily StrombidaeLobatus mulepenensis (Petuch, 1994)Location: Imokalee, Collier County, Florida USA.

Crepidula depressa Say, 1822 Location: SMR Phase 10, Sarasota County, Florida USA. Status: Extant Notes: Flat to concave due to its preference for attachment on the inside of the aperture of dead gastropods. Fossil species have traditionally been named Crepidula plana also a species still living today. Molecular studies have shown that although nearly identical in appearance C. depressa is a different species restricted to the warmer waters of Florida while C. plana extends along the Northern Atlantic as far south as the Carolinas and Georgia. -

Crepidula fornicata (Linneaus, 1758) Location: SMR Phase 10, Sarasota County, Florida USA. Status: Extant Notes: Most examples of this species both fossil and living are highly inflated and demonstrate stacking. Compare to LINK. The vast majority of this species from the Sarasota pits are much less inflated. These might represent ecomorphs. -

Crepidula cymbaeformis (Conrad, 1841) Location: APAC, Sarasota County, Florida USA. Status: Extinct Notes: Longer than wide with apex extended from the body of the shell. Campbell (1994) noted the ability of the animal to absorb hematite into the interior of the shell which helps in identification. -

Bostrycapulus aculeata aculeata (Gmelin, 1791) Location: SMR Phase 10, Sarasota County, Florida USA. Status: Extant Notes: Small low relief with several rows of longer spines among many more rows with smaller spines. -
From the album: Gastropods of the Tamiami Formation
Bostrycapulus aculeata ponderosa (H.C. Lea, 1843) Location: APAC, Sarasota County, Florida USA. Status: Extinct Notes: Campbell (1994) listed all spiny slipper shells from the Southeastern USA as one of two subspecies of the extant B. aculeata. Subspecies ponderosa is highly inflated and it is variable in terms of spines as stacked individuals will remove spines of individual below. Due to different life style from extant B. aculeata this could be considered a separate species. -
