truceburner Posted November 1, 2012 Share Posted November 1, 2012 I'm no gastropodiatrist, but I think this specimen is Athleta petrosa. It was found in Shoal Creek in Austin, TX, which has everything from Cretaceous to last Thursday, but I suspect this is Eocene. It's not the most pristine gastropod I've ever found, but it has some nice detail on the whorls. What do you think? Link to comment Share on other sites More sharing options...
erose Posted November 1, 2012 Share Posted November 1, 2012 I think it washed out of someone's backyard after it was brought home from the gulf. Link to comment Share on other sites More sharing options...
jkfoam Posted November 2, 2012 Share Posted November 2, 2012 Well, I can see why you think it may be Athleta petrosus. It has the general look. However Athleta petrosus has a much shorter spire compared to the lenth of the body whorl. Also, Athleta petrosus has three folds on the columella. While you don't show a photo of the aperature of the specimen one photo shows a break in the shell that exposes the columella and I don't see evidence of the folds.
