Shellseeker Posted April 6, 2020 Share Posted April 6, 2020 Like many these days, I am sorting and cleaning up the previous month's finds. I do not recall picking this up, probably considered it a fragment or barracuda tooth. It is 17 mm long and 6.5 mm wide, and slightly concave on one side. 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

Mark Kmiecik Posted April 6, 2020 Share Posted April 6, 2020 Dermal denticle of some kind possibly? Spur? Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
Shellseeker Posted April 7, 2020 Author Share Posted April 7, 2020 2 hours ago, old bones said: Perhaps; Thanks, There have been examples of Petrochirus claws found in the Peace River. I can search TFF and find them. It looks close but a little different. I have send an email to Roger Portell Collection Director of Invertebrate Paleontology at University of Florida. He collects Florida crabs. I will let you know when he responds. @digit The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
digit Posted April 7, 2020 Share Posted April 7, 2020 Definitely no barracuda tooth--but if that might have been what motivated you to keep it rather than toss it back, it was a good thing. I found a tiny piece of Petrochirus yesterday while picking some micro-matrix (a great was to pass the time while not out and about). I fairly regularly encounter dactyls (fingers) from the chela (claw/pincher) while picking micro-matrix but less often spot them while out in the river with a sifting screen. Does not match my concept of a tortoise leg spur (osteoderm) as they are solid and have a distinctive constriction at the base. The shape, surface texture (and hollowness) do look about right for a Petrochirus dactyl. I'd be interested to hear what Roger has to say. He may be harder to get a hold of at the moment but we eagerly await his opinion here.
