Although lots of changes occurred 65 mya (million years ago)-1.8 mya (when the age of the mammals/Tertiary Period started) bunches of other important things evolved and changed before and after the Tertiary Period. Mammals originated in the The Permian Period, humans evolved in the Quaternary Period to become us and the first life came in the Precambrian time. Now today we are changing the earth way to fast. Global warming caused by pollution has changed the average temperature of the earth by 2º in 17 years when it takes about 1,000 years for the earth to do naturally. During the Tertiary Period mammals where the main thing. They thrived after being small and vulnerable to the dinosaurs. Grass took off evolving creating an opportunity for grazing mammals. The Tertiary was named the age of the mammals for a reason, because there where so many.
