Small Exogyra?

Recommended Posts

Okidreamz

Hello! I am new to the forum and new to fossil hunting in general. I have a 6 year old son that loves to dig and search for fossils. We were hoping for some help identifying these fossils. There is a park that we go to and there are TONS of these fossils all over the ground. From what we've researched, they look like exogyra except they are smooth and tiny. We have no clue what they are and would appreciate any help! They were found in San Antonio, TX if that helps. Thanks in advance!

Those are "devil's toenails". They are Gryphaea sp.

You should be able to find echinoids (sand dollars), bivalves (clams), gastropods (snails) and ammonites in the same strata.

Good Luck!

Just about any six year old boy is going to like the name "Devil's Toenails"!

Heck, I'm almost 60, and I still like it :)

I stand corrected! San Antonio is definitely your area, Dan!

I have a question about Ilymatogyra arietina. Are they found only in the Del Rio Formation in Central Texas?

Thanks,

David
