Hey!

 

CVO Menu - The Geologic Time Scale

Pliocene

5.3 to 1.8 million years ago

Final epoch of the Tertiary period. It is named after the Greek words "pleion" (more) and "ceno" (new).

 

Miocene

23.0 to 5.3 million years ago

A epoch of the upper Tertiary period. It is named after the Greek words "meion" (less) and "ceno" (new).

 

A neat 5.3 Million year ago dividing line, eh?

 

NOVA Online/Cracking the Ice Age/The Big Chill

 

...a second major cooling period so intense that by 7 million years ago southeastern Greenland was completely covered with glaciers, and by 5-6 million years ago, the glaciers were creeping into Scandinavia and the northern Pacific region. The Earth was once more released from the grip of the big chill between 5 and 3 million years ago, when the sea was much warmer around North America and the Antarctic than it is today. Warm-weather plants grew in Northern Europe where today they cannot survive, and trees grew in Iceland, Greenland, and Canada as far north as 82 degrees North.

 

Geologic time scale - Wikipedia, the free encyclopedia

5.332 - 3.600 Mya

Intensification of present Icehouse conditions, present (Quaternary) ice age begins roughly 2.58 Mya; cool and dry climate. Australopithecines, many of the existing genera of mammals, and recent mollusks appear. Homo habilis appears.

 

Thanks! :confused:
