Age of the Mammals

65 million years
or 16 meters to today

Geolo­gi­cal era: Ceno­zoic / Palaeogene

At the end of the Cret­ace­ous period a cosmic cata­stro­phe occur­red. A meteo­rite smas­hed into Central America and, probably due to conti­nen­tal drift, enor­mous volca­nic erup­ti­ons occur in India (Deccan-Trapp). This is follo­wed by a drama­tic drop in tempe­ra­ture with conti­nen­tal icing and a drop in sea level. In the sixth mass extinc­tion trig­ge­red by this, the dino­saurs disap­pear — with the excep­tion of the birds. The versa­tile mammals conquer the entire planet.

The climate is about 4 °C warmer than today, i.e. subtro­pi­cal. The sea level is much higher than today, as are the oxygen and CO2 content of the air. The flora and fauna spread over a new land bridge between Africa and Eura­sia. In Austra­lia, animals and plants deve­lop comple­tely differently.
