LSCHNELLE Posted October 31, 2020 Share Posted October 31, 2020 I found this in Central Texas Basal Atco Conglomerate with Ptychodus latissimus and Ptychodus atcoensis. It is only about 15 mm to 20 mm tall, including a partially bilobed (?) root and worn tooth crown. Any ideas? Fish or squamate? Link to comment Share on other sites More sharing options...

Have you considered a rostral tooth from a sawfish ? Cheers, Brett 3 Link to comment Share on other sites More sharing options...

LSCHNELLE Posted November 1, 2020 Author Share Posted November 1, 2020 Thanks Troodon. I think that appears to be a match. Center spine is very close - less surface wear. Link to comment Share on other sites More sharing options...
