During the Cenozoic, mammals proliferated from a few small, simple, generalised forms into a diverse collection of terrestrial, marine, and flying animals, giving this period its other name, the Age of Mammals. The Cenozoic is just as much the age of savannas, the age of co-dependent flowering plants and insects, and the age of birds. [40]

An approximate timescale of key Cenozoic events. Vertical axis scale: Millions of years ago The European Land Mammal Mega Zones (abbreviation: ELMMZ , more commonly known as European land mammal ages or ELMA ) are zones in rock layers that have a specific assemblage of fossils ( biozones ) based on occurrences of fossil assemblages of European ...
[4] [8] Overall, during the Late Pleistocene about 65% of all megafaunal species worldwide became extinct, [9] rising to 72% in North America, 83% in South America and 88% in Australia, [10] with all mammals over 1,000 kilograms (2,200 lb) becoming extinct in Australia and the Americas, [1] and around 80% globally.

Unprecedented global warming will wipe out all mammals during a mass extinction event in about 250 million years, according to a new study.. The world’s continents are predicted to eventually ...
The Cenozoic begins with the extinction of all non-avian dinosaurs, pterosaurs and marine reptiles, and features the great diversification in birds and mammals. Humans appeared and evolved during the most recent part of the Cenozoic.
