The divisions of the geologic time scale are divided into four eras. from earliest to closer to the present is the Precambrian, Paleozoic, Mesozoic, Cenozoic. During these time periods, there were several major evolutionary events. Most commonly known are the dinosaurs and humans. Hope that helped :)
Precambrian Era
Dinosaurs lived during the Mesozoic Era.
Dinosaurs lived during the Mesozoic Era.
No, dinosaurs existed during the Mesozoic era, which ended about 66 million years ago. The Cenozoic era began after the Mesozoic era and continues to the present day, during which mammals became the dominant land animals.
Yes it was
Precambrian
It is very empty and only single-celled organisms were present in the Precambrian era. No animals were living on land because of the poisonous gas in the air.
100 types of dinosaurs lived during the mesozoic era.
The Precambrian Era. Basically, the only life present in Earth was that of single-celled bacteria.
Dinosaurs lived during the Mesozoic era.
The Eras go like this: Precambrian Era Paleozoic Era Mesozoic Era Cenozoic Era Dinosaurs lived during the Mesozoic Era, and we live in the Cenozoic Era. Paleozoic means "ancient life" Mesozoic means "middle life" Cenozoic means "recent life" All eras end in a huge disaster
