That makes the assumption that the animal in question survived because it 
continued to engage in active predation.
Another possibility is that it was forced by its injuries to be an obligate 
scavenger in order to survive. Yet another 
possibility is that dilophosaurs formed close social bonds with each other that 
allowed an incapacitated animal to
continue to benefit from the prey acquisition of the rest of the group.
