Mesozoic"s era"s cretaceouis period (reptiles and dinosaurs) And the beginning of the cenozoic era"s tertiary period (65mya) Epochs: paleocene (65-55mya, eocene (55-34mya) global warming occurred (warm and wet, oligocene (34-24/23 mya) cooling/dry cycle (grasslands appear, miocene (24/23-5 mya) age of apes (warm and wet forest expansion, pilocene (5 mya) Oligocene epoch: earliest african apes (first hominods- semi-terestrial) 11-5 mya: gap in the fossil record, sachelanghropus orroin and ardipithecus ramidus. 8-5 mya: cold/dry period = tropical forest constriction/ retraction, bipeds first seen (prediction) = first hominoids= change in hip structure. 4. 5 mya: widely excepted evidence for first bipeds (ardipithecus ramidus) Pliocene epoch: various biped species and migrations out of africa. New ecological niches (due to k-t boundary)- meteorite impact: cooling occurs- many species died out, survivors = leaders of new lineages, adaptive radiation of placental mammals. Generalized species becomes many more specialized species.
