Fossilized crab claw?

Say where this was found. Remember: provenance is essential in assisting in the successful identification of specimens.

Nope. No need. I think I've got this one. It's a fossilized crab claw.

I’m currently on vacation in Punta Cana, Dominican Republic, and found it on the beach here, it was found in Quaternary period rocks.

Kidding. In reference to species question. But I suppose it might not be a crab claw.

I would not rule out that this whatever this may be might also be modern if it washed up on the shore.

Tooth tap test ?

@Rockwood how would you do that?

If this helps here’s some more photos from different angles.

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.

It makes a higher pitched sound!

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:
