jsharyn27 Posted October 20, 2016 Share Posted October 20, 2016 Found this recently in Del Rio, TX in shallow water at a recent mud & rock slide due to collapse of cliff. It's about the size of an average man's fist. Link to comment Share on other sites More sharing options...
Troodon Posted October 20, 2016 Share Posted October 20, 2016 Looks like an ammonite. I'm sure someone can give a much closer ID as to genus Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 20, 2016 Share Posted October 20, 2016 Welcome to the Forum. Could be a heteromorph ammonite. Could also be a gastropod. Not sure. Wait for a few more local opinions. Neat find. Regards, Tim - VETERAN SHALE SPLITTER VFOTM - APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

JohnJ Posted October 20, 2016 Share Posted October 20, 2016 As mentioned, it is a partial heteromorph type ammonite. Do a Forum search for Mariella. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
hobbitfeet Posted October 20, 2016 Share Posted October 20, 2016 I found something similar in a park in Austin which I think was the Del Rio Claystone or the Georgetown formation. It's called Plesioturrilites brazoenosis. Here's a useful guide to Texas fossils. http://www.lib.utexas.edu/geo/ggtc/ch2.html#dr Link to comment Share on other sites More sharing options...
fifbrindacier Posted October 20, 2016 Share Posted October 20, 2016 I agree this is an ammonite. Nice find jsharyn27. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

erose Posted October 20, 2016 Share Posted October 20, 2016 Genus has been bounced around a bit but Mariella and Plesioturrilites are pretty much the same thing. Link to comment Share on other sites More sharing options...
Twinlukers Posted October 20, 2016 Share Posted October 20, 2016 Nice!!! yes it's an ammonite. I still have not found one like that here in Texas but they are around. It could also be a Gastropod. but with some cleanup who knows Link to comment Share on other sites More sharing options...
abyssunder Posted October 20, 2016 Share Posted October 20, 2016 Maybe Mariella brazoensis ? https://www.google.com/search?q=mariella+brazoensis&biw=1360&bih=612&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjg8YTpqurPAhXEuRQKHeScBUwQ_AUIBigB " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
