And overall what was going on during those times* What traits would you look for: where do we see these traits occurring, petrosal bulla, derived hands and feet, grasping, nails, decreased reliance on smell, forward facing eyes, etc. Evolution of primates: family tree: * there is a family tree picture * Paleocene: plesiadapiformes: primitive, they retain a number of ancestral mammalian traits, some plesiadapiformes possessed some but not all derived primate traits, not clear if they fall within or just outside of, the primate evolutionary tree, paleocene- 65-55 mya. Eocene (cid:862)da(cid:449)(cid:374)(cid:863) mammals we know today diversified: 55-34 mya, 1st true primates occurred- adapoids and omomyoids, first primates of modern aspect, adapoids, elongated snout, many were diurnal- small orbits, probably ancestral to strepsirrhines.
