Slow Walker Posted July 25, 2022 Share Posted July 25, 2022 This fossil has many grooves, holes and structures. My only guess is it's a part of a skull of mosasaur or plesiosaur. Any ideas? Or good reference pics of skull parts for comparison? Thanks Link to comment Share on other sites More sharing options...

This plesiosaur skull had many shapes. https://sketchfab.com/3d-models/plesiosaur-dolichorhynchops-osborni-ea5a73c3fe2843679f59305b67f099a8 Link to comment Share on other sites More sharing options...
Slow Walker Posted July 27, 2022 Author Share Posted July 27, 2022 Couldn't find good mosasaur skulls to compare. This one is missing the back of head. https://sketchfab.com/3d-models/fossils-of-mosasaurus-skull-e1c2a80e42aa4ba0848ef5c308673707 Link to comment Share on other sites More sharing options...
rocket Posted July 29, 2022 Share Posted July 29, 2022 (edited) do you know Moroccan Mosasaurs - General Fossil Discussion - The Fossil Forum ? shows many elements in the thread perhaps, might be it helps a little bit, this is for free: (PDF) Rediagnosis and redescription of Mosasaurus hoffmannii (Squamata: Mosasauridae) and an assessment of species assigned to the genus Mosasaurus (researchgate.net) Edited July 29, 2022 by rocket 1 Link to comment Share on other sites More sharing options...

I think it's the 3rd one here but hard to tell. https://www.researchgate.net/figure/Squamosal-of-MNHN-AC-9648-in-a-left-lateral-view-b-left-dorsal-view-c-left-medial_fig4_303090121 1 Link to comment Share on other sites More sharing options...
