michaelzzz Posted July 10, 2017 Share Posted July 10, 2017 Hi all, Found couple interesting fossils need help to ID. They were from Post Oak Creek in Sherman, Texas. First four pictures are a tooth of some sort, last three are a half dollar size bone fragment. Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 10, 2017 Share Posted July 10, 2017 The bone is too water worn to say what type of bone it is. Could be mosasaur, as well as the tooth. Wait for some locals to chime in before assigning a label, though.

michaelzzz Posted July 11, 2017 Author Share Posted July 11, 2017 Thank you Fossildude19. Could the tooth be plesiosaur? Mosasaur tooth seems to be more stumpier from the pictures saw online Link to comment Share on other sites More sharing options...
michaelzzz Posted July 13, 2017 Author Share Posted July 13, 2017 Any other suggestions? Also picked up this tooth and another bone. Anyone know what they are? Thanks in advance Link to comment Share on other sites More sharing options...
Chase B. Posted July 14, 2017 Share Posted July 14, 2017 Dear @michaelzzz, Firstly, the Post Oak Creek site yields marine fossils from the Turonian-Coniacian Eagle Ford Shale. Here are identifications for your specimens. The first tooth is that of an indeterminate plesiosaur (though likely an elasmosaur, as this is a Late Cretaceous deposit). The second fossil is a chunk of bone from Chunkosaurus (a nickname we give to bone scraps from the field). The third specimen is a jaw fragment from a Pachyrhizodus sp. fish, and the fourth specimen is a partial squamosal from Mosasauridae indet. Congratulations on these finds. Regards, Chase To clarify, the fourth specimen is the ventral portion of a mosasaur squamosal 1 Link to comment Share on other sites More sharing options...
Al Dente Posted July 14, 2017 Share Posted July 14, 2017 The object on the keyboard is a side cusp with part of the root of a Cretodus tooth. Here is a picture I pulled of this thread about Post Oak Creek showing some Cretodus teeth. I added yours to it as a comparison.Post Oak 2 Link to comment Share on other sites More sharing options...
