I would also like some clarification on this.  I was in Paris about a month 
ago, and although my trip through the museum was rushed, I did see some 
spinosaurid material, including a nice thumb claw.  If I recall correctly, this 
claw was ascribed to the genus Spinosaurus.  As Beri noted, there have been no 
Spinosaurus thumb claws discovered as of yet.  

Does this claw actually belong to "Cristatusaurus" or am I mistaken (is it not 
actually labeled Spinosaurus)?
