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.
