These several stages of the Cenozoic were also characterised by great vicissitudes of geography and climate.
No dinosaurs are definitely known to have crossed the line into the Cenozoic era.
Paleozoic means "ancient life;" Mesozoic, "middle life;" Cenozoic, "recent life."
Miocene , that period of the Cenozoic era when apes were transformed into man.
The Cenozoic era comprises two divisions,—the Tertiary period and the Quaternary period.
In the early part of the fourth great geological Time--the Cenozoic--nearly the whole continent was above water.
During the early part of the Cenozoic era birds became still more advanced and numerous, with many modern groups represented.
Poisonous snakes were not evolved until early in the next (Cenozoic) era.
The next geological era is the Cenozoic, or period of modern life.
Why, Trednoke, do you realize that we are living literally at the bottom of a Mesozoic—at any rate, Cenozoic—sea?
The most recent era of geologic time, from about 65 million years ago to the present. The Cenozoic Era is characterized by the formation of modern continents and the diversification of mammals and plants. Grasses also evolved during the Cenozoic. The climate was warm and tropical toward the beginning of the era and cooled significantly in the second half, leading to several ice ages. Humans first appeared near the end of this era.
