Averaged about 7 kg.
Still a monkey essentially.
Might have had a tail?
Combination of primitive and advanced features.
Relatively long snout.
Larger brain than prosimians—still below the limit for monkeys.
Eye orbits still relatively laterally facing.
Substantial sexual dimorphism (males larger than females).
Fusion of the mandibles.
Reduced olfactory structure. Large visual cortex in the brain (compared to prosimians).
Cup-like orbits closed off behind with postorbital plates.
Miocene Primates (24-5 mya)
Primitive hominoids (apes) first appear in the fossil record of East
Africa around the start of the Miocene.
≈ 17 mya Africa collided with Eurasia—radiation of anthropoids
(monkeys and early apes) into the rest of the Old World.
