Prehistoric Life 23-2.6 Million Years Ago. During the course of the Neogene period, life on earth adapted to new ecological niches opened up by global cooling--and some mammals, birds, and reptiles evolved to truly impressive sizes in the process. The Neogene is the second period of the Cenozoic Era (65 million years ago to the present ...

The beginning of the Tertiary coincides ...Cenozoic climate-carbon cycle fluctuations can be studied using δ 18 O and δ 13 C records from deep-sea benthic foraminifera (see Materials and Methods). Hyperthermal events are identified by paired negative excursions in δ 18 O and δ 13 C and have been interpreted as rapid global warming events caused by the release of isotopically depleted organic carbon into the surface environment.The stepwise cooling marks the long-time global climate change during the Cenozoic, particularly since the Oligocene/Eocene boundary. This climatic evolution has been punctuated by several warming such as the peak Cenozoic warmth at 52 Ma, the late Oligocene warming at ∼25 Ma and the Mid-Miocene Climatic Optimum at 17-14 Ma.Concurring with the global temperature changes, the Asian ...Mesozoic and Cenozoic Eras.

The continents continued to spread apart to reach their present day positions. Sea levels rose and fell, affecting the coastline, but the ...The key approach to reconstructing deep ocean temperatures, especially through the early Cenozoic, has been the analysis of the oxygen isotopic composition of shells of benthic foraminifera (δ 18 O b) from deep ocean sediments. δ 18 O b reflects deep ocean temperature but also seawater isotopic composition (δ 18 O sw) at the time of shell formation.The canonical view has been that before ...The Cenozoic era allowed mammals to flourish in the absence of dinosaurs. Mammals evolved to fill the spaces left by the dinosaur extinction. Smaller mammals grew bigger during this period. These mammals also took the dominating position dinosaurs had over other animals.
