Rockwood Posted March 11, 2020 Share Posted March 11, 2020 Nope. No need. I think I've got this one. It's a fossilized crab claw. 1 Link to comment Share on other sites More sharing options...

In reference to species question. But I suppose it might not be a crab claw. 1 Link to comment Share on other sites More sharing options...

Rockwood Posted March 11, 2020 Share Posted March 11, 2020 Gently tap it against your front teeth (after properly cleaning). It may take some experimenting, but I find the sound it makes is a good way to tell. If it's a fossil the pitch will be higher and it will seem to strike harder because it is denser. 1 Link to comment Share on other sites More sharing options...

dinosaur man Posted March 12, 2020 Author Share Posted March 12, 2020 I have found some things on crabs from these areas and times, and I think this might be a Gecarcinus sp., here’s the paper: https://www.researchgate.net/figure/Fossil-Quaternary-terrestrial-crabs-from-Antigua-and-Bermuda-A-E-Coenobita-sp-cf-C_fig1_313425485.
