Help to identify fossil vertebra from Morocco, please

[JavierMS]

Greetings, I recently bought a fossil vertebra from a moroccan seller who claimed it was a Plesiosaurus vertebra, and through I did not believe him I made a deal with him and I got the fossil for a cheap price. My guess it that it belongs to an Otodus chark or an Enchodus fish, is a quite big vertebrae anyway... What do you think? Thank you very much in advance.

Not a shark vertebra could be plesiosaur.  Can you post a photo of the side.
