Okidreamz Posted January 10, 2013 Share Posted January 10, 2013 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! Link to comment Share on other sites More sharing options...
Boneman007 Posted January 10, 2013 Share Posted January 10, 2013 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! Link to comment Share on other sites More sharing options...

Auspex Posted January 10, 2013 Share Posted January 10, 2013 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 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

Riverbilly Posted January 10, 2013 Share Posted January 10, 2013 I have a question about Ilymatogyra arietina. Are they found only in the Del Rio Formation in Central Texas? Thanks, David Link to comment Share on other sites More sharing options...
