Most of the questions you ask are not really answerable. We

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?
