Geologic Time Scale-II

The two most recent eras on the geologic time scale are the Mesozoic and the Cenozoic eras, which followed the Paleozoic era.

The Mesozoic Era, also known as the Age of Reptiles, lasted from 252 to 66 million years ago.

It started with the Triassic period, which saw the first flying reptiles, dinosaurs, and mammals.

During the Jurassic period, dinosaurs became diverse and abundant. At the end of the final Cretaceous period, another mass extinction occurred, wiping out the dinosaurs from Earth.

Next, the Cenozoic era, our current era, is called the age of mammals. This era began 66 million years ago and continues to the present.

It includes three periods: Paleogene, Neogene, and Quaternary. This era started with the evolution of early primates and saw the rise of humans. In the later stages of this era, the extinction of large mammals and birds occurred.

The last epoch of this era, the Holocene Epoch, is important as human beings started agriculture and the domestication of animals during this time.
