charlie3425 Posted May 17, 2021 Share Posted May 17, 2021 This piece of spine with 4 verts was found in the fosfat beds of Morocco. It is supposed to be Plesiosaur, but the form is different I think. Might be Mosasaur, although I have never seen these trianglar shaped studs on the sides of the vertebrae. Does anyone recognize the shape? The whole piece is appx 40cm long and a good 20 cm wide.

frankh8147 Posted May 17, 2021 Share Posted May 17, 2021 Yep! Concave/convex; we are looking at Mosasaur here. Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted May 17, 2021 Share Posted May 17, 2021 Yup, mosasaur vertebrae are procoelous, while the vertebral arrangement of plesiosaurs is amphicoelous to amphiplatian. The triangular projections off of the vertebral bodies are transverse processes that would've functioned more or less the same way as ribs. 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...
