TERTIARY ERA

TERTIARY ERA
from 65 to 2.5 million years ago
(or Cenozoic)

The continents reach their current positions.

The climate becomes drier,
therefore
forests decrease and savannas form.

Large mountain ranges form: the Alps and the Apennines, the Pyrenees, the Carpathians, the Balkans and the Caucasus.

Life forms adapt to the new changes.

65 million years ago
Mammals and birds spread all over the planet.

10 million years ago
A new group of mammals appears, similar to monkeys: primates.

4.8 million years ago
Mammals become larger, like the mammoth, and very similar to modern ones.

4 million years ago
Australopithecus appears,
an ape that learns to walk upright.
