Hyperthermal events were the highlight of this period. Intense Volcanism and Large-Scale Greenhouse Gas emissions shaped the climate during the beginning of this period into the permanent ice cap formation of the Oligocene epoch. There were many global-scale Biogeochemical and Climate based extremes that shaped the fauna and mammals of this time period.

The end of the Cretaceous period was marked with a mass extinction that was heavily debated, but leans towards a volcanic eruption. The climate during the Paleocene and Eocene Epochs was warm and humid, a greenhouse climate, much warmer than the temperatures we experience today. The transition into the Oligocene turned colder. Most creatures that lived during this period were some of the first mammals, and according to fossils found during the beginning of the Cenozoic, were small herbivores.
