Assuming this is a crab claw. I found on Panama City Beach, Florida, yesterday morning.

Greetings, found a fantastic crab claw and pieces on the NC southern coast. I believe them to be from the PEE DEE formation.

I've been out to the Lake Waco Research Area (or just the Waco Pit as many people call it) about nine or ten times so far this year. Over the course of those trips I've found a lot of interesting things such as several species of sharks' teeth, some very small sea urchins, fish vertebrae, and of course the common pyritized miniature ammonites. But I've also found several things that I have yet to definitively identify, such as the three finds that I'm making this post about. First is a small piece of shale with a peculiar pattern that runs off the edge. It reminded me of millipede tracks people have found in Carboniferous deposits and so I decided to keep it and do some research later, not really thinking it was anything special. But to my surprise it seems to match up with pictures of hermit crab trackways (Nereites) quite well, with the indented line representing where the shell was dragged across the ocean floor and the tiny diagonal markings on either side having been made by the legs. I'm not exactly sure why the line in the center of the trackway is depressed into the shale as a negative while the "footprints" are raised positives, however, although it does seem to look that way in some of the pictures of modern hermit crab footprints I saw online as well. The other thing I can't figure out is why the trackway (if that's actually what it is) starts in the middle of the piece of shale rather than continuing off the edge in another direction. If the crab had been dropped onto the ocean floor and then began moving I would expect to find some sort of depression marking where it had landed at the beginning of the trackway but I don't see anything like that. The second find is also crab-related and is one half of a claw. I've found other crab claws before at the pit, but they're usually much smaller and rounded with dimpled marks and come from a species of hermit crab called Pagurus banderensis. This lower half of a claw is larger than a full set of pincers from Pagurus and looks nothing like them. So which Cretaceous crab does it belong to? The last find is a fish tooth. Although fish vertebrae are incredibly common in the pit, their teeth are not. I've only ever found isolated Enchodus fangs before, and this is not one of those. It's much thicker and is proportionally shorter. My best guess is Pachyrhizodus or Protosphyraena but I'm not sure; it could very well be an Enchodus tooth, just a lateral one. Thanks for looking everybody! Any help with ID's is greatly appreciated.
