Ant100: week 4: general patterns of morphology and phylogenetics for fossil primates, what a hominid is in terms of taxonomy, morphological trends in hominin evolution:! Time frame and climate: paleocene (6. 5 mya - 55. 8 mya): ber hot, no ice caps, world is getting colder on a geologic time frame! Madagascar and india hasn"t bumped into asia to form himalayas, modern day europe underwater, africa is a hospitable place! Main oil producing areas of the world are covered by water, small organisms falling to ! ocean and produced oil through pressure and heat! Body size: tiny, shrew0sized to size of small dog, abundant in fossil record! Niche: likely solitary, nocturnal quadrupeds; well developed sense of smell! Used to be classi ed as primates because of primate-like teeth and limbs that ! are adapted for arboreal lifestyle! They have no postorbital bar (eye sits in well of skull, primitive mammalian condition)!
