Description

Impressive piece. It is a long bone that lacks the proximal and distal epiphysis. This is a problem for their correct identification. However, its morphology is very reminiscent of the huge neural spine of the Spinosaurus dorsal vertebrae. This piece is still under study and comparison.

But the most interesting part of this piece is the association of this bone with three  shark vertebrae in anatomical connection, supported on the bone. Undoubtedly, it is a capricious and unique fossilization. It has some fractures that have been glued and restored by the filling method.

This piece was recently prepared  by our expert. We leave a link to the video where you can enjoy the whole preparing process:

The bone rests from the sites in the south of Morocco are very scarce and valuable because of many reasons. One of them is the very same nature of the geological formation that contains them. The sediments were formed in delta and fluvial environments, where the transportation energy was relatively high. Because of this, any possibility of finding articulated rests is very rare, since the rests of dead animals where transported and deteriorated. That is why only the most robust bones or the most stable parts are usually preserved. Another reason for the lack of complete dinosaur bones in this region is the destructive methodology normally employed by the local miners in their excavations, which in the search of teeth, usually destroy many interesting bone rests.
