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!

Order Trocida Family Calliostomidae Calliostoma mitchelli philanthropus (Conrad, 1834) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA. Status: Extinct Notes: This top shell displays quite a bit of variation. Conrad (1834) described both C. mithchelli and C. philanthropus. Later authors such as Dall (1892) and Mansfield (1930) placed several subspecies within C. philanthropus. Of 30 Calliostoma species/subspecies from the Upper Pliocene, Campbell (1993) recognized 19. Two stocks were dominate C. virginicum and C. mitchelli which took page precedence over C. philanthropus and which former subspecies are now named. -
I've just found this big bivalve in pliocene level from south of France.

Forgive me if I am posting in the wrong section. But I have been to Green Mill Run once last year, and am looking to go this week. I am on vacation in North Carolina but a couple hours away. There has been quite a bit of rain which I know can make Green Mill Run unavailable to Fossil hunting. I could not find a way to determine what the water level might be like, and I don't know how fast the creek empties from water after rains. By any chance if anyone that lives in the area familiar with this location could give me a heads up if it's worth my drive there to Fossil hunt with my nine-year-old son and family that would be awesome. If not we might just make the drive and peek into the creek, but if it's not available we would rather go to the Natural History Museum in Raleigh I guess. Thank you very much for anyone that could help, I know it's short notice but if we get there I will certainly post a report!

I haven’t been keeping any Ecphoras that I find because I have all I want but this one looked like it could be pretty big. Turned out not to be very big but big enough to be interesting. It was found in a river outcrop with a little bit exposed. Normally small ones can be easily cleaned with a toothbrush and soapy water but bigger ones tend to have cracks. This one had plenty of cracks and rotten spots that made it fragile. It had to be preserved with vinac. Here are some pics during prep.

Recently I acquired a specimen of Jianghanichthys hubeiensis from @RJB (big thank you, I'm really happy with the Jianghanichthys!). I was examining the fish, but I then noticed there was a small portion of organic material exposed on the back of the matrix. I started prepping, curious to see what was there. I ended up with a small fish. The fish is only a bit over an inch in length. So far I've only seen one dorsal and one ventral fin (one of these fins were flaked off during preparation.....oops) My image shows an illustration of where the missing fin was placed. If anybody knows the ID of these fish, I would be eager to know. Specimen is from Songze, Hubei, China.

Port Jackson Shark crushing tooth collected from Beaumaris, Victoria. The first I have ever collected.
-
G'day all, Today I decided to go down for a hunt at Beaumaris with my dad and make good use of the low tide. For those who don't know, the fossils from Beaumaris come from the Beaumaris Sandstone Formation, aged 6.5-4.5 million years ago (late Miocene to early Pliocene) and around 30 minutes from Melbourne. To find the fossils we searched through the shingle on the beach that had been washed up from a phosphatic nodule bed which can only be partially accessed at low tide and is where most of the vertebrate material derives from. Fossils from this site include: Shark and ray teeth, fish jaws and teeth, ceteacen bones and teeth, bird bones, seal bones, terrestrial mammal bones, rare turtle shell, corals, bivalves, gastropods, nautiloids, crustaceans, brachiopods and echinoids. Despite the water being very cold (And falling into the water on my way out of the site) We found many good fossils today, many of them firsts. The Site Tusk Shells (Laevidentalium) Sea Urchins (Lovenia Woodsi) Port Jackson Shark teeth (Heterodontus cainozoicus) Toadfish crushing tooth plates (Diodon) Shark tooth (Shortfin Mako?) Assorted bone fragments (Most likely Cetacean)
