Blue stripe gryphalope (and another thing too)

Ok, so now i think i've got a plan of how to go about creating the helix world. Im going to go through the continents, doing as many animals for that continent as i can, and also some extinct helix world animals from time to time. Now im going through Acaria (Africa's analogue)

Gryphalopes, like the Blue stripe gryphalope shown above, are cursorial hippogryphs of the Acarian savannah, living like earth zebras. They live in large herds of up to 10,000 animals and like almost all hippogryphs they cannot fly. They are a common prey item for many predators.

The smaller animal is a Plains Unicorn, which unlike most Helix world mammals are NOT rodents. They are lagomorphs. (I said there was going to be at least one kind of non-rodentian mammal.)
