From the album: Gastropods of the Tamiami Formation
Order Littorinimorpha Family Cypraeidae Siphocypraea ketteri Petuch, 1994 Statigraphy: Golden Gate Member of the Tamiami Formation Location: Near Imokalee, Collier County, Florida USA. Status: Extinct Notes: Another form transitional between S. carolinensis and S. problematica. Differs from S. trippeana by having a wider shell and flattened base with noticeable wrinkles along the base. Petuch assigns this species in the genus Pseudadusta. -

Order Littorinimorpha Family Cypraeidae Siphocypraea lindae (Petuch, 1986) Statigraphy: Golden Gate Member of the Tamiami Formation Location: Near Imokalee, Collier County, Florida USA. Status: Extinct Notes: Very close to S. carolinensis with a high dorsum and simple sulcus but with a narrower posterior aperture and stronger denticles on parietal lip. Petuch assigns this species in his genus Pseudadusta. -

Order Littorinimorpha Family Cypraeidae Siphocypraea transitoria Olsson & Petit, 1964 Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC, Sarasota County, Florida USA. Status: Extinct Notes: Although common in the Kissimmee River area, this specimen is from APAC in Sarasota where it is much rarer. Very close to S. problematica with slightly less coiling of the anterior sulcus and a slightly wider posterior aperture. Petuch would call this Siphocypraea streami.-

Order Littorinimorpha Family Cypraeidae Siphocypraea hughesi Olsson & Petit, 1964 Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: Kissimmee River, Highlands County, Florida USA. Status: Extinct Notes: Restricted to the Kissimmee River area. Distinctive shape, wide and squat. Anterior sulcus approaching that of S. problematica. Petuch assigns this species to Akleistostoma (Olssonicypraea). -

Order Littorinimorpha Family Cypraeidae Siphocypraea trippeana Parodiz, 1988 Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC, Sarasota County, Florida USA. Status: Extinct Notes: Typically, shell is small and narrow with a high dorsum. The sulcus has a slight bend more so than the S. carolinensis complex, described as a keyhole appearance and a narrow aperture like S. problematica. -

Order Littorinimorpha Family Cypraeidae Siphocypraea carolinesis floridana (Mansfield, 1931) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10, Sarasota County, Florida USA. Status: Extinct Notes: Highly variable much more so than S. carolinensis. The dorsum tends to be not as high as S. carolinensis and parietal denticles are more strongly expressed but shares the uncoiled anterior sulcus and wide posterior aperture. This is the common Siphocypraea found in the Sarasota shell pits. Also, Akleistostoma. -

Order Littorinimorpha Family Cypraeidae Siphocypraea carolinesis floridana (Mansfield, 1931) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC, Sarasota County, Florida USA. Status: Extinct Notes: Example of a gerontic individual of this subspecies. -

Order Littorinimorpha Family Cypraeidae Siphocypraea sarasotaensis Petuch, 1994 Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC, Sarasota County, Florida USA. Status: Extinct Notes: First described as a Siphocypraea, Petuch later classified this species with his Calusacypraea genus which is defined by neotenic characteristics such as an undeveloped anterior sulcus and very light weight. Many researchers feel that this species is merely a variation of S. floridana (Lyle Campbell pers. comm.). WoRMS classification Siphocypraea while Petuch would call this species Calusacypraea myakka. -

Order Littorinimorpha Family Cypraeidae Siphocypraea briani (Petuch, 1996) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC, Sarasota County, Florida USA. Status: Extinct Notes: Described as Calusacypraea briani and differentiated from S. sarasotaensis by having a larger and longer shell. I have placed this shell as S. briani however it could be a gerontic individual of S. sarasotaensis. Some Cypraeidae demonstrate sexual dimorphism which could explain the larger size as well. WoRMS classification Siphocypraea, Petuch Calusacypraea. -

Order Littorinimorpha Family Cypraeidae Cypraea sp. Statigraphy: Ochopee Limestone Member of the Tamiami Formation Location: Canal spoil, Collier County, Florida USA. Status: Extinct Notes: Presence of a distinct spire suggests that these internal casts do not belong to the genus Siphocypraea. -
Hi Gang, looking for some insight on several Tamiami formation Pliocene aged Sarasota County, Florida inverts. Found this gastropod at work a couple weeks ago as the rains exposed some new material in the road fill. Trying to confirm if its a Phyllonotus globosus. It also had a neat little Chama inside...saving it for my Chama ID project that I may get to some day....

So I ran across 2 more gastropods from Sarasota Florida APAC that have been hiding in the garage--well maybe not hiding--just buried in the junk. Doesnt seem to be something common unless I have some tiny ones somewhere. Probably Tamiami Fm. Plio-Pleistocene. Thought they were the same initially and I had lumped them together. But now I see the one on the right has a depressed end. So maybe a Prunum sp. and a Bullata sp? that would be cool. Thanks for the looks and any feedback. Regards, Chris

Hoping someone easily recognizes these and its an easy answer...my initial searches have been fruitless... So I was supposed to be looking for more Florida coprolites in the garage piles of fossils and got sidetracked looking as this large Turbinella columella and just noticed these tan circular markings on it and wanted to know if they were traces of serpulids? Probably Pliocene Tamiami formation, Sarasota County, Florida. Whats fascinating to me is their spiral?/concentric, ornamented/segmented? shape which appears to actually be etched into the gastropod shell itself. Almost look like cross sections of forams. I've scraped a number of the small white serpulid tubes off thinking I'd see a similar pattern but there is no marking beneath them--its perfectly smooth. If it is a tube, I wasnt aware that they could actually score the surface of the gastropod shell--seems pretty neat if thats what going on but maybe its something entirely different. The gastropod, aside from being badly damaged has sponge borings, barnacle and coral encrustration, and serpulid tubes. Most of the circular traces are around 1mm in diameter and a few push the 2 or 3mm size. Thanks for the help! Regards, Chris

Well so much for getting distracted again...Uggh! I need to pay attention..Anyways, I just realized I created an earlier thread for a gastropod that I was labeling as a bivalve.oops..I also do need help with actual bivalve IDs....both are from APAC spoils Sarasota County. Possibly Beds 10 or 11 lower Tamiami formation. Thinking the first one is a Chama. Matrix removal has been a bear on these.. And the 2nd I was thinking it might be Marvacrassatella but thats just a guess. I'm going to consolidate the exterior hopefully this week and then separate the valves to get a look at the scar/hinge area if they can be separated. Thanks for any help/confirmation. Regards, Chris
