New Members dannbethrfriends Posted July 2, 2023 New Members Share Posted July 2, 2023 Hi all, my daughter and I found this bone in the north sulfur river up near the Dallas/ Fort Worth Texas area a few weeks ago. It seems to be a reasonably complete structure of some kind but I sure don't recognize it! I really appreciate any help! 1 Link to comment Share on other sites More sharing options...

GPayton Posted July 3, 2023 Share Posted July 3, 2023 Could also be part of a turtle plastron, but if not it's likely fish. Link to comment Share on other sites More sharing options...
Mikrogeophagus Posted July 3, 2023 Share Posted July 3, 2023 Looks like a neural spine to a large fish probably Xiphactinus. I found a couple similar heavily pyritized ones in the Austin Ozan: Link to comment Share on other sites More sharing options...
New Members dannbethrfriends Posted July 4, 2023 Author New Members Share Posted July 4, 2023 Thank you so much, all! Looking at neural spines, I think that's exactly it! Link to comment Share on other sites More sharing options...
Harry Pristis Posted July 4, 2023 Share Posted July 4, 2023 It appears to be a pinna, a fin spine from a fish. It appears to be to be chunkier than it should be, likely bone overgrowth which makes it a Tilly bone. http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
