|
Characteristics of Plesiadapiforms: |
- About 75 species - some diurnal, noturnal, size from small mouse to medium sized house cat - probably retained many primitive mammalian traits |
|
|
Two examples of Plesiadapiformes? |

Present in North America, Europe, Asia, and Africa; 56-34 mya |
|
|
Characteristics of Adapoids:
|
- 80 different species
- Size: large rat to large housecat - Probably gave rise to strepsirhines (lemurs & lorises) |
|
|
Two examples of Eocene primates? |
- Adapoidae - Omomyoidea
Located in N. America & Europe |
|
|
Three genera of Adapoids |

|
|
Adapis |
|
|
Omomyoids Characteristics |
- similar appearance to the modern tarsier - most from Europe and N. America - shared common ancestor of tarsiers, monkeys and apes |

|
|
Oligocene Epoch |
Climate fluctuations affected primate ranges, 32-24 mya |
|
|
Type of Parapithecidae |
Apidium |
|
|
Apidium Characteristics |
- some similarities to new world monkeys - about the size of a squirrel monkey - might be the ancestor of platyrrhines and catarrhines |
|
|
Type of Parapithecidae |
Aegyptopithecus |
|
|
Aegyptopithecus Characteristics |
- probably an early catarrhine - possible ancestor to both old world monkeys and apes - teeth are comparable to those of hominids; Y5 molars |
|
|
Miocene Epoch |
- the cooling reversed temporarily and warmer temperatures were experienced for a time - tectonic activity, pushing the Himalayas upward - 24-5 mya |
|
|
Miocene Hominoid Characteristics |
- primarily arboreal - ape-like heads - body was a mixture of ape-like & monkey-like features - modern hominids, no tail - about 30 genera |
|

Miocene Hominid: European Form |
Dryopithecus - 8 genera existed from 13-8 mya |
|
|
Dryopithecus Characteristics |
- size of a large monkey or small golden retriever - possible ancestor of modern humans |
