I actually thought more about this since my last reply- could make it so if a dinosaur goes into hunting behavior and another of the same species is within radius, one of them goes into the squaring-off stance and the prey dinosaur turns it's attention there as sort of a distraction. Meanwhile, the other carnivore goes into stalking animation and takes the prey down. Upon killing it, both dinosaurs feed from the carcass. Large carnivores could be limited to pair cooperation, small carnivores maybe two or three. So picture a raptor squaring off to a parasaur and two others simultaneously stalk and jump it at the same time, taking it down in unison. Then all three feed from it together
