New Members Gokaden Posted December 3, 2018 New Members Share Posted December 3, 2018 Hello, I live in Austin, TX, and my house sits on top of the Glen Rose formation from the late Cretaceous. I usually find bi-valve oyster shells and the like in my yard, but came across something bigger today that seems like it's from a non-invertebrate. Can anyone provide information on what this fossil might be? Thanks. Joe Link to comment Share on other sites More sharing options...
ynot Posted December 3, 2018 Share Posted December 3, 2018 Welcome to TFF. Looks like a chamber of an ammonite shell. 5 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted December 3, 2018 Share Posted December 3, 2018 +1 for partial ammonite. Very pretty. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
ClearLake Posted December 3, 2018 Share Posted December 3, 2018 Welcome from a fellow Texan. Agree with ynot, very definitely an ammonite. The “bumps” are from the complex suture of the chambers which can be very diagnostic in identifying a specimen. This one may be a bit too worn for very definitive ID, but a nice find none the less.

New Members Gokaden Posted December 3, 2018 Author New Members Share Posted December 3, 2018 Hi everyone, thanks a bunch for the quick responses. Great to know that there are ammonites in my yard. I'm hoping to find an intact one in the future! Link to comment Share on other sites More sharing options...

Ludwigia Posted December 3, 2018 Share Posted December 3, 2018 A non-invertebrate would be a vertebrate, which an ammonite is not, so I guess you meant that it's an invertebrate Greetings from the Lake of Constance.
