The Eocene Epoch
When was it?
58 to 37 million years ago.
What was going on?
Mammals and birds continue to diversify. The first prosimians appear.
What were the continents like?
Things look pretty modern, but a lot of the lower areas are under water.
South and North America have not yet connected, nor has Africa bumped into Eurasia. The
Bering land bridge between Eurasia and North America is open.
What kind of life existed?
Mammals and birds continue to fill the niches left open by the departed Dinos. The
cetaceans (whales) appear. The first prosimians appear, which are the first group of primates
which still exist today.
