dodo4 Posted May 30, 2017 Share Posted May 30, 2017 I would appreciate any help in identifying the fossils below. I have many pieces like the ones in the picture. They are basically very similar in shape with a ridge/line on the back. I find most of my fossils walking the beaches near South Ponte Vedra, FL Link to comment Share on other sites More sharing options...

Al Dente Posted May 30, 2017 Share Posted May 30, 2017 These are all pieces of turtle bone. Most are from the midline of the carapace. 4 Link to comment Share on other sites More sharing options...

Let me tell you why I have doubts about it being a part of a turtle carapace. I have several larger pieces of turtle carapace and they dont look like they would come apart in fragments similar to the ones shown above, they look solid. I will post a few pictures later.

Al Dente Posted May 30, 2017 Share Posted May 30, 2017 Here's an illustration from Wikipedia showing individual bones in a turtle carapace. Turtle shells will eventually fall apart into these individual bones if given enough time. 3 Link to comment Share on other sites More sharing options...
dodo4 Posted May 30, 2017 Author Share Posted May 30, 2017 What can I tell you Al, you are the MAN! Thank you! This answers soooo many questions for me, as I have plenty of turtle shell fragments 39 minutes ago, Al Dente said: Here's an illustration from Wikipedia showing individual bones in a turtle carapace.

jpc Posted May 31, 2017 Share Posted May 31, 2017 some turtle neurals can be Id'ed to genus by their shape and their ornamentation. That is certainly what these are. 1 Link to comment Share on other sites More sharing options...
