It appears that the front of the skull would be towards the right of the 
picture (judging from the size of the sockets), and that the teeth were 
probably longer than wide, though not by much. The tooth line appears to be 
straight at the rear, and upturning mildly at the front. This appears to be 
different than the max. of _Tyrannosaurus_, _Daspletosaurus_, 
_Yangchuanosaurus_, _Ceratosaurus_,_Dromeosaurus_,_Deinonychus_, _Troodon_ 
and _Allosaurus_. _Dilophosaurus_ has a similar sharp upturn, however the 
posterior portion of the tooth row is not a straight line. Unfortunately, I 
do not have an illustration of _Spinosaurus_, or any African theropod for 
that matter, so I can't really say. It looks to be about half a meter long, 
but this is just a guestimate. My guess would be a sort of spinosaur, but I 
also don't know a whole lot about them, so this is just my opinion.
Peace,
