snolly50 Posted July 14, 2021 Share Posted July 14, 2021 (edited) @RickCalif Size? Stab at this point - Halisaurus.

Praefectus Posted July 14, 2021 Share Posted July 14, 2021 I'm thinking Halisaurus also. I'm not sure of the species, but Halisaurus arambourgi seems like a good fit. @jnoun11 @pachy-pleuro-whatnot-odon Could you confirm? Thanks. Link to comment Share on other sites More sharing options...
RickCalif Posted July 14, 2021 Author Share Posted July 14, 2021 The teeth measure out at 11mm in length Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted July 14, 2021 Share Posted July 14, 2021 Yup, definitely would say Halisaurus arambourgi partial mandible for this one. The type of foramina seen here is consistent with mosasaur mandible, and the diminutive size and minimal degree of curvature is typical of H. arambourgi. 2 hours ago, Praefectus said: I'm thinking Halisaurus also. I'm not sure of the species, but Halisaurus arambourgi seems like a good fit. Currently, since the description of Pluridens serpentis, there's only one remaining species of Halisaurus recognized within the Moroccan phosphates. And while P. serpentis is also a halisaurine mosasaur, it's teeth are notably different, exhibiting striations around the base of the crown and being more recurved. P. serpentis teeth are also usually notably larger than those of H. arambourgi.

jnoun11 Posted July 16, 2021 Share Posted July 16, 2021 hi i think also ,halisaurus arambourgi. The trouble with having an open mind, of course, is that people will insist on coming along and trying to put things in it. Terry Pratchett ...
