Order Littorinimorpha Family Cassidae Semicassis granulata (Born, 1778) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC Pit, Sarasota County, Florida USA.

Order [unassigned] Caenogastropoda Family Cerithiopsidae Seila adamsii (H.C. Lea, 1845) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 8 Pit, Sarasota County, Florida USA.

I was hunting with a couple of TFF friends doing a ground search in an area that produces 90% marine fossils, Megs, Makos, but no GWs, Whale /Dolphin earbones and vertebrate, ray teeth, fish verts, dugong rib bones with a few mammal bones and teeth, primarily horse. I found this jaw section: My initial take was whale, but then too small for whale and I switched to gator. I have seen no alligator teeth and lots of whale material. Is there anything besides size that would confirm or eliminate one or the other ?. Thanks for comments, suggestions, IDs.

Busycon maximum is a geographically widespread shell found only in the Upper Pliocene of the Southeastern United States. Form alumense from the Florida Panhandle differs from B. maximum found in the Sarasota shell pits by lacking shoulder knobs and in having a more compacted spire.

Need help to identify the following fossil. It was found in Milos, preserved in volcanoclastic sediment and diatomite. Data from a study in the area suggest late pliocene to early pleistocene. Looks like an echinoderma, but unlike any I've ever seen, since it's test appears to have layers and no apparent mouth (unless it's on the bottom part). I have even considered it being a cystoid or some coral, but I haven't had any luck researching my theories. Units on the pic with the ruler are cm and size is about 4.5cm. Any suggestion would be much appreceated!

R. Catesbaiana Angulosplenials from the SW Florida Pliocene. Keep on finding an abundant precense of Amphibians 5.3 to 2.5 million years old in what is now Glades County, FL. Interesting that also shark teeth are present. Both lacustrine and sea environment in only 2.8M years. Sunday Funday!

Is there enough of this guy for anyone to guess at an ID? Both valves are present, the side with the (I think...) plicatula gibbosa stuck to it is barely there, and heavily, heavily worn, but present. I've had it for quite a while, haven't found a match for it yet, but I also have no clue how much might be missing. I'm hoping the severe shelf on it will be enough for someone. Sw Fl, pliocene. Any help appreciated!

Hi guys have this bone fragment from The Caloosahatchee Formation of South West Florida Late Pliocene/Early Pleistocene. I know it is small and perhaps unidentifiable as it is a fragment but wanted to throw ir out there. Have a few more bones will post shortly.

Last week I was on holiday in the Netherlands/Belgium and I found many things! I mainly hunted at the beaches near Cadzand but I was also in the area of Antwerp. There the quality of the shark teeth is much better and you can find more and rarer ones At the sand pit the Miocene, Pliocene sand was washed up from the extension of Churchill dock and as you can see the area is very overgrown. You can still find there many shark teeth, bones and bivalves. I mainly concentrated on finding shark teeth. The best method to find something there is to dig a bit and then sieve the material. Here is a picture of the site: The total haul: The better ones: This was one of the best finds: Its about 5 cm long and I think that its an Isurus Hastalis (please correct me if I am wrong ) I like the colors on this one: (3.5 cm) A sweet little Galeocerdo Aduncus tooth: (1.2 cm) And last but not least this was probably my rarest find there: Small but nice Its an upper tooth of Somniosus microcephalus. I already have a lower tooth but thats the first upper for me! I am very happy with it Thanks for watching and I hope you enjoyed my little hunting trip! Of course any ID help is welcome!
