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 |

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 |
