Hell Creek - Tiny jaw bones

Recommended Posts

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!

The roundness of the tooth holes indicate piscivory, maybe champosaur?

Cool finds! I believe the are sections of Melvius thomasi dentaries...a fish called an amiid or bowfin.

I definitely agree that they look like fish jaws but I don't know amiid jaws at all.
