Carl Posted December 22, 2022 Share Posted December 22, 2022 Pretty sure they are not croc teeth. They look a bit mammalian, but the attachment to the jaw is all wrong for that. My best guess is that it is a large fish. Interesting! 1 Link to comment Share on other sites More sharing options...

Mahnmut Posted December 22, 2022 Share Posted December 22, 2022 Hi bratqueen and welcome to the forum. To me it looks as if the teeth where part of the bone rather than sitting in sockets, which would exclude mammals and crocodilians. http://palaeos.com/vertebrates/bones/teeth/tooth_implantation.html Best Regards, J 1 2 Try to learn something about everything and everything about something Thomas Henry Huxley Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted December 22, 2022 Share Posted December 22, 2022 Welcome to TFF, Bratqueen! You've come to the right place with your question, as we've got quite a few knowledgeable members here 6 minutes ago, Mahnmut said: http://palaeos.com/vertebrates/bones/teeth/tooth_implantation.html Useful link, Jan! Great overview of the terminology in use! I'm bookmarking it! 1 hour ago, Carl said: Pretty sure they are not croc teeth. They look a bit mammalian, but the attachment to the jaw is all wrong for that. My best guess is that it is a large fish. Interesting! I can confirm, these are not crocodile teeth, as they would be more conical and fitted into sockets in the jaw. As Jan moreover mentioned, these can't be mammal teeth either, as those would also be socketed. A large fish would be possible, especially with blunt teeth like that. But these seem to be rooted in a way that I don't think fish teeth typically are. And while I believe lizard teeth typically have a different morphology that makes them look more leaf shaped, I still wanted to propose these may have come from a larger type of lizard? For comparison: Dentaries of modern phrynosomatid lizard specimens (source) Maybe @JohnJ or @jpc would have idea about this? 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...

Al Dente Posted December 22, 2022 Share Posted December 22, 2022 (edited) Troodon is on the right track. It is definitely fish and most likely some type of wrasse.

Mahnmut Posted December 22, 2022 Share Posted December 22, 2022 I first thought of a wolf eel, which did not fit exactly, but look at those teeth! 1 Try to learn something about everything and everything about something Thomas Henry Huxley Link to comment Share on other sites More sharing options...
Mike from North Queensland Posted December 22, 2022 Share Posted December 22, 2022 Welcome to the forum. Wrasse are found in the Darwin area so would be a good candidate. I live in Townsville but I moved from Darwin about 50 years ago though 1 Link to comment Share on other sites More sharing options...
