ANIMALS OF THE CENOZOIC ERA!

TIME PERIOD

TIME PERIOD☻ 65 Million Years to the Present

☻ Starts from the end of the Cretaceous.

♫ and the extinction of non-avian dinosaurs to the present.

♫ shortest era

Where fossils were located?

NAMES FOR THIS ERA☻ Age of

mammals

☻ Age of flowering plants

☻ Age of Insects

☻ Age of birds

PALEOGENE PERIOD☻ Climates changed from

warm and moist to cool and dry.

☻ Some pants developed flowers and insects expanded.

☻ Some large mammals evolved and the first whales evolved.

Neogene period ☻ The Neogene

Period began about 24 million years ago

☻ Connections between continents where created.

☻ The continents collided and found modern mountains chains

Consequences ☻ The

mountains changed environment so animals had to change to adapt.☻ Continents positions changed ocean currents which changed the weather.

☻ Connections between continents caused land animals migrations.

Quaternary Period ☻ During the

quaternary period the positions of the continents were much the same as they are today

☻ Various ice ages that come and go.

Between 6 and 7 million years ago

a group of mammals began

an adaptive radiation that will lead to modern

humans.

There was so much frozen

water that sea level fell

over 100 meters

The age of humans☻The first homo sapiens occurred around 190,000 year in Africa.

☻As the brain got bigger, and we became smarter migrations to other continents occurred.

☻The low seas permitted easier migrations to continents.

☻Some scientists have concluded that the big mammals of the quaternary age disappeared because the hunting methods of humans.

☻During ice ages humans migrated to equator looking for warmer land , but as glairs melted they returned to the north.

Some facts

☻ If earth history was compressed in one hour, flowers will only exist for the last 90 seconds., and humans for the last 7 seconds.

☻Some birds where 7 feet tall.

☻Which was the biggest mammal ever?
