M Harvey Posted September 28, 2021 Share Posted September 28, 2021 Looks reptilian to me. My vote is for a very eroded mosasaur jugal. Link to comment Share on other sites More sharing options...
Harry Pristis Posted September 28, 2021 Share Posted September 28, 2021 Is the jugal represented by the prominence at "F"? http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
Carl Posted September 28, 2021 Share Posted September 28, 2021 It's pretty weathered, so it's hard to be certain, but I'm seeing Enchodus. Link to comment Share on other sites More sharing options...

The broken surfaces and overall shape run counter to a mosasaur jugal. 29 minutes ago, Harry Pristis said: Is the jugal represented by the prominence at "F"? The jugal defines the lower portion of the eye orbit.

pachy-pleuro-whatnot-odon Posted September 28, 2021 Share Posted September 28, 2021 I also don't see a mosasaur jugal in this...

Al Dente Posted September 28, 2021 Share Posted September 28, 2021 It's Enchodus. You can see the scars on your fossil from the replaced fangs as the fish grew. Here is a photo of another example showing these scars from "The Oceans of Kansas" website. 5 1 Link to comment Share on other sites More sharing options...
