LordWampa Posted March 20, 2023 Share Posted March 20, 2023 Hi, just wanted to double check if the ID of this mosasaur jaws is correct and if there is any composite stuff (at least from may point of view I can't see any). This first in theory it's a Eremiasaurus heterodontus from Oued Zem. The second one it's a Prognathodon curii also from the same place. Tagging @Praefectus and @pachy-pleuro-whatnot-odon. Thanks guys!! 1 Link to comment Share on other sites More sharing options...
Praefectus Posted March 20, 2023 Share Posted March 20, 2023 I recognize that piece. I believe it was one of Boubker Chaibi's finds from last year. I still have the pictures on my computer. The pieces are both original. I agree with the identifications: Eremiasaurus heterodontus mid-jaw section and Prognathodon currii pterygoid(?) or posterior section. 1 1 1 Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted March 20, 2023 Share Posted March 20, 2023 I agree, both identifications match and both pieces are authentic. Especially the P. currii piece is quite a stunner. Not just beautiful preservation on the teeth, but I do think it's a pterygoidal piece, seeing as the strong backwards curvature and smaller size of the teeth. 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...
LordTrilobite Posted March 21, 2023 Share Posted March 21, 2023 100% agree with those IDs. I'll add that the Eremiasaurus jaw piece is the front of a left maxilla. 2 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

From thalassotitan would be the correct id? It's listed as Leidon Anceps, but now it's Thalassotian right?

It's listed as Leidon Anceps, but now it's Thalassotian right? Yes. They are Thalassotitan atrox teeth (=Prognathodon anceps, Leiodon/Liodon anceps, Prognathodon sp. nov. "Mosasaurus anceps"). The teeth appear to be marginal crowns, not pterygoids. I have to caution you that the attached jaw pieces look to be composites. The crowns are glued onto spare mosasaur jaw sections. 1 Link to comment Share on other sites More sharing options...
