abctriplets Posted July 29, 2017 Share Posted July 29, 2017 We were exploring the Hell Creek Formation in Montana, and found very similar sections of jaw bone. It seems like structurally, this section was the strongest and most likely to survive. As you can see, they are very small... Any idea on what these might have come from?? Thanks for any tips!

Miocene_Mason Posted July 29, 2017 Share Posted July 29, 2017 The roundness of the tooth holes indicate piscivory, maybe champosaur? “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
PFOOLEY Posted July 29, 2017 Share Posted July 29, 2017 Cool finds! I believe the are sections of Melvius thomasi dentaries...a fish called an amiid or bowfin.

Carl Posted July 31, 2017 Share Posted July 31, 2017 I definitely agree that they look like fish jaws but I don't know amiid jaws at all. Link to comment Share on other sites More sharing options...
