Wightlight Posted July 4, 2018 Share Posted July 4, 2018 (edited) I got this tooth as a freebie when I bought some fossils a while ago. I know it's a mosasaur tooth of some description and my guess would be Prognathodon sp. based on how common they are, but I'd like confirmation (if possible) for my own peace of mind. I know it's not easy ID'ing based on tooth crowns, but hope springs eternal. The tooth is about 3.5 cm long.

Bone guy Posted July 4, 2018 Share Posted July 4, 2018 Doesn't look stocky enough to be Prognathodon. Maybe Platecarpus indet.? 1 Link to comment Share on other sites More sharing options...

Yeah, that was the one detail that sort of made me waver on it being Prognathodon. Wouldn't a Platecarpus tooth have striations at the base though? 1 Link to comment Share on other sites More sharing options...

You'll have to get more opinions from members with more knowledge on this. @LordTrilobite Link to comment Share on other sites More sharing options...
LordTrilobite Posted July 4, 2018 Share Posted July 4, 2018 Though it is a bit thin mediolaterally, I would lean towards Prognathodon sp. . But Eremiasaurus heterodontus might be a better bet as that one also has teeth that are sometimes similar to Prognathodon, but depending on the tooth position they can be quite slender indeed. But I'm not sure if the teeth in the back, which are a little fatter, are also mediolaterally flattened like this tooth here. It's not Platecarpus ptychodon to be sure. As Wightlight said, it would have had striations on the bottom half of the tooth. P. ptychodon teeth are among the most distinct in the Khouribga area. Though more and more it seems that P. ptychodon is probably not in the genus Platecarpus. 3 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

Could be a contender. Link to comment Share on other sites More sharing options...
