Re: Dilophosaurus Forelimb Bone Maladies

The notion that dilophosaurs may have been at least partially piscivorous (i.e. 
spinosaur wannabes) is 
interesting, as it might explain the long neck, long narrow teeth, and kinked 
croc-like snout. A 
piscivore that only targeted aquatic prey that could be swallowed whole would 
have little need to 
employ the forelimbs at all in predation.

It also offers a possible explanation as to what may have happened to this 
individual's forelimbs. A 
combination of fractures and punctures is exactly what you would expect from an 
attack by a 
crocodilian. Puncture wounds from crocodilian teeth have a tendency to become 
infected, as was the 
case for the puncture wounds in this specimen.
