Marine reptile rib

[FF7_Yuffie]

I more than likely buy this fossil anyway because of its very low price--unless somebody spots something wrong, like it being two seperate bones stuck together

 

But I figured I'd see if anyone can narrow down more what it's from.

 

It's labelled as unidentified marine reptile rib from the Taouz Morocco. The seller says possible plesiosaur, mosasaur or crocodile.

 

It is 9cm long. 

 

Probably very difficult to identify closer, really. It's a long shot, but hey, anyone has a better idea and can narrow it down so I can label it more precisely than "marine reptile rib" that would be great.

 

Thanks very much.
