Plesiadapiforms

60mya not primate like

What's so special about Carpolestes?

it was a plesiadapiform that had some primate characteristics of grasping hands and feet and a nail on the big toe.

Angiosperm Radiation Hypothesis

primates evolved to fruit eating in the trees

Visual predation hypothesis

evolutionarily favored due to hunting insects

arboreal hypothesis

lived in trees

Euprimates

the first 'true' primates that had grasping hands and feet, nails, larger brains, forward facing eyes, postorbital bar, and generalized teeth; 34-56mya

Adapids

diurnal, larger, sexually dimorphic, vertical incisors, NO TOOTH COMB, strepsirhine-like (lemurs)

Omomyids

nocturnal, smaller, short snout, tarsier-like

What was the Earliest Haplorhine?

Archicebus (55mya), originated from asia, tarsier-like (small, arboreal, sharp cusped teeth) and anthropoid-like (small eyes, monkey like feet).

Earliest Anthropoid

Eosimias, china, anthropoid-like teeth (generalized and dental formula, large canines) short anthropoid like heel

What kind of climate trend has been occurring in the Cenozoic?

cooling trend for the last 65mya

Oligocene

epoch; 23-34mya;global cooling

Earliest Anthropoids

29-37mya; composed of parapithecids, oligopithecids, and propliopithecids

parapithecids

29-37mya; most primitive of the three, NW monkey dental formula (2-1-3-3), OW monkey body structure, postorbital closure, leaper.

oligopithecids

29-34mya; arboreal quadrupeds, OW monkey dental (2-1-2-3)

propliopithecids

32mya; largest size, OW monkey dentition (2-1-2-3), fruit diet, sexual dimorphism, arboreal, diurnal, small brain.

Aegyptopithecus

a propliopithecid from 30 mya; primate-like (forward eyes and grasping hands), anthropoid-like (short snout and post orbital closure), ape-like (2-1-2-3), and monkey-like (tail, quadruped)

Saadanius

28mya; bony auditory tube that is found in all OW and apes (not found in aegyptopithecus)

Gigantopithecus

found in asia from 8 to 0.5 mya; name based on size they stood over 10 feet; broad, flat molars and premolars; MIOCENE

Sivapithecus

MIOCENE ASIAN ape; lived from 12mya to 8mya; thick enamel to consume tough foods

Oreopithecus Bambolii

8mya in EUROPE; MIOCENE; extinct after 1mya; long forelimbs; shared some of the anatomical features associated with bipedalism.

Dryopithecus

MIOCENE; EUROPE; 13-10mya; similiar to chimps, large brains, slow life history; went extinct

Morotopithecus Bishopi

MIOCENE; AFRICA; 20mya; moved like an ape by arm hanging and vertical climbing; low cusped molars and premolars; y-5 pattern; sexually dimorphic canines

Afropithecus Turkanensis

MIOCENE; AFRICA; 16-18mya; broad incisors, y-5 molars with low cusps, large canine with diastema; simian shelf.

Kenyapithcus Wickeri

MIOCENE; AFRICA; later miocene; y-5 molars

Which primates are in the Eocene?

56-34mya; adapids, omomyids

Which primates are in the Oligocene?

34-23mya; Aegyptopithecus, saadanius, propliopithecids, parapithecids, and oligopithecids

Which primates are in the Miocene?

23-5.3mya; proconsulids, dryopithecus, sivapithecus, khoratpithecus, gigantopithecus, oreopithecus

victoriapithecids

miocene primates from Africa, possibly ancestral to OW monkeys
