Fishinfossil Posted September 28, 2021 Share Posted September 28, 2021 Found in NJ Cretaceous stream. Thick Enchodus jaw or ??? Thanks. Link to post Share on other sites
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 post Share on other sites
Harry Pristis Posted September 28, 2021 Share Posted September 28, 2021 Is the jugal represented by the prominence at "F"? Link to post Share on other sites
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 post Share on other sites
JohnJ Posted September 28, 2021 Share Posted September 28, 2021 1 hour ago, M Harvey said: Looks reptilian to me. My vote is for a very eroded mosasaur jugal. 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. (Noted as "j" on Russell's diagram in Systematics and Morphology of American Mosasaurs.) 1 2 Link to post Share on other sites
pachy-pleuro-whatnot-odon Posted September 28, 2021 Share Posted September 28, 2021 I also don't see a mosasaur jugal in this... Link to post Share on other sites
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 1 Link to post Share on other sites
