    Need Help With ID Of Fresh Water Fossil.

    First things first, I am quite a neophyte to the world of fossils.

    I found this large shell while kayaking the San Marcos River. I regularly hunt Indian artifacts and I think this one appears to have some type of flint in the outer-most layer.

    It is VERY brittle. It also has what appears to be "fossilized" sand in the deepest recess.

    If anyone could shed some light on this one for me I would be in your eternal debt! I always find shells while kayaking but never one this large and colorful.

    Thank you for any help in advance.

    It's a marine fossil, Cretaceous in age. It's one valve of Exogyra sp.
