Re: poor Einiosaurus

Stop using mammal behaviour as a guide...think behaviours that are a mix of reptile and bird. More reptile-like for the ornithiscians and sauropodomorphs , and bird-like for the theropods. Flocking and congregating more than pack hunting and herding behaviours.

Dixon (2006) lists this Centrosaurine as living during the Campanian stage of the late Cretaceous, contemporary with Gorgosaurus and Daspletosaurus. With a nose horn that pointed down, when one of these large tyrannosaurids was closing in I can't see Einio doing much outside of tapping "S.O.S." on the ground with it. Could it "ram" the legs of these hungry predators, toppling them or breaking leg bones with this horn? It just doesn't seem to be of much obvious use against an adult - especially Daspletosaurus. I don't know what the current view is of how fast Einio could run away, or if there was some sort of inter-species herding with better equipped-for-defense herbivores. Seems to be an easy lunch?
