Strangely Spiked Skulls

Syndoceras was a type of protoceratid, a now-extinct group of hoofed mammals with bony horns like those of today’s pronghorn and cattle. The forked nose horn was almost as long as the brow horns. The sequence of skulls at left shows how these horns evolved to be longer in later species (see this page).

“Pigs from Hell”

Once known by the evocative name Dinohyus (“fearfully great hog”), the entelodont Daeodon (“dreadful tooth”) must have been a terrifying presence in these grasslands. Omnivorous animals with enormous heads, entelodonts resembled overdeveloped boars with gigantic canines. Matternes observed that “teeth like that are really the anatomy of aggression” and portrayed this animal as the king of the beasts—but he gave no hints as to his assessment of its dietary preferences.
