From the album: Gastropods of the Tamiami Formation
Order Neogastropoda Family Muricidae Vokesimurex rubidus (F.C. Baker, 1897) Statigraphy: Golden Gate Member of the Tamiami Formation Location: Boca Grande Aggregates, Lee County, Florida USA. Status: Extant Notes: Its common name is the Rose Murex. -

Order Neogastropoda Family Muricidae Calotrophon ostearum conradi (Mansfield, 1930) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC, Sarasota County, Florida USA. Status: Extinct Notes: The spire is higher and body whorl sculpture stronger than extant C. ostrearum. Possible intergrades exist between C. ostrearum and C. ostrearum conradi would exclude C. conradi to be considered a separate species, however it is a form that does not exist in recent populations. -

Varix ornamentation can vary significantly based upon environmental conditions. Compare this specimen from a fine grained sheltered habitat to that of MR 10239-1028 which lived in a high energy environment. Reference Campbell, Lyle. 1993. Pliocene Molluscs from the Yorktown and Chowan River Formations in Virginia. Virginia Division of Mineral Resources Publication 127.

Mansfield (1930) described the Jackson Bluff (Chocatawahatchee) Formation species as Ecphora qudricostata umbilicata. Campbell (1993) and Lauck Ward (personal communication) agree that all named species and subspecies of Ecphora from the Upper Pliocene are variations of a single species E. quadricostata. Both consider Ecphora bradleyae Petuch, 1986 as the only other valid Upper Pliocene Ecphora. Reference Campbell, Lyle. 1993. Pliocene Molluscs from the Yorktown and Chowan River Formations in Virginia. Virginia Division of Mineral Resources Publication 127. Mansfield, W.C. 1930. Miocene Gastropods and Scaphopods of the Choctawhatchee Formation of Florida, Florida Geological Survey Bulletin 3, 189 pages.

Typically I would not photograph an imperfect specimen however this is a species that neither Campbell or Ward and Gilinsky list from the Chowan River Formation. References Campbell, Lyle. 1993. Pliocene Molluscs from the Yorktown and Chowan River Formations in Virginia. Virginia Division of Mineral Resources Publication 127. Ward, L. W., and Gilinsky, N. L. 1993.

From the album: ECHINOIDS & OTHER INVERTEBRATES
Here are three fairly common gastropods from the Pliocene Caloosahatchee Beds in SW Florida. These represent two different families: Turbinellidae and Muricidae. I have duplicates of these shells.© Harry Pristis 2013
