M Harvey Posted February 11, 2019 Share Posted February 11, 2019 I am hoping someone can provide some some guidance. The surface of this bone is covered with knobby protuberances. My inclination is fish but the bone cell structure is not fish flaky but more reptilian. Found in Alabama, Cretaceous chalk. 3 Link to comment Share on other sites More sharing options...
Carl Posted February 11, 2019 Share Posted February 11, 2019 Nice! That sure looks like a fragment of the turtle Naomichelys. 5 Link to comment Share on other sites More sharing options...

JohnJ Posted February 11, 2019 Share Posted February 11, 2019 Until I saw @Carl's post, I was thinking crustacean...it's hard to see if there is internal bone texture or just matrix highlighted by glue. 2 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

Thank you for the quick response. I knew someone out there would have the answer. I will check with the McWane museum to see if they are interested.

Brittle Star Posted February 12, 2019 Share Posted February 12, 2019 Hi I would go with turtle I have a piece also from the Isle of Wight, Sandown. Never ask a starfish for directions Link to comment Share on other sites More sharing options...
Plax Posted February 12, 2019 Share Posted February 12, 2019 You turtle guys are good! I had it as a possible hybodont (Lissodus?) spine fragment. Guess the curve threw me off. It is a turtle marginal then? Amazing how nature repeats morphologies. Laid out differently it also somewhat resembles a pycnodont tooth plate (definiitely not of course) 1 Link to comment Share on other sites More sharing options...
