Dino vertebra unknown

[val horn]

I ended up with a fossil with almost no id.   (I need to avoid fossil shows;  where I can yield to temptation)   It is reported to be a Moroccan  dinosaur vertebrae. 

If anyone can make a educated guess as it its species, age and formation,  based on its preservation and shape, I would greatly appreciate it. 

It is a rough oval 14 cm by 10 cm and 9 cm in height

I could be wrong, but it looks more like a marine reptile. And if it's Morocco, maybe Goulmima material based on color.

I agree... pretty worn but large plesiosaur vertebra (notice, the singular does not have an e at the end).  See the two little holes on the bottom side in the last photo?  Those are pretty diagnostic of plesiosaurs.   The left hole has some matrix in it, but the right hole is more subtle.
