they were the cretatious triassic and jurassic
Triassic
Mesozoic Era
The Paleozoic precedes the Mesozoic. And our current era, the Cenozoic, follows the Mesozoic.
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 :)
The Paleozoic Era of geologic history occurred before the Mesozoic Era.
Precambrian Era, Paleozoic Era, Mesozoic Era, Cenozoic Era
Mesozoic era is called the era of creepers.In this era there are three periods viz Triassic,Jurassic and carboniferous. It is found that in Triassic era, reptiles were evolved and in Jurassic era they were dominant.That is why Mesozoic era is called the era of creepers/reptiles.
Divisions of an era are called Periods.
It really wasn't an era. An Era was a much longer period of time. It was called the "Jurassic Period".
The era for the age of dinosaurs is called the mesozoic era.
it was when reptiles first started
Triassic
Age of Reptiles
Mesozoic Era
The Paleozoic precedes the Mesozoic. And our current era, the Cenozoic, follows the Mesozoic.
The Mesozoic Era is known as the Age of Reptiles.
The dinosaurs lived in the Mesozoic Era, which includes the Triassic, Jurassic, and Cretaceous periods. The first dinosaurs appeared in the late Triassic and went extinct at the end of the Cretaceous.
