Dinosaurs
Mesozoic era
The dominant organisms in the Mesozoic Era were dinosaurs, which ruled the land, along with marine reptiles and ammonites in the oceans. In the later part of the era, mammals and birds began to diversify and emerge as important groups of organisms.
The Mesozoic Era
No. The dinosaurs rose in the Mesozoic era. The end of the Mesozoic era was also the end of the dinosaurs. The era following is the Cenozoic, which we are still in today.
Precambrian
There was giant reptiles, dinosaurs and other monstrous beasts.
The Cenozoic era was not a subdivision of the Mesozoic era. The Mesozoic era is subdivided into the Triassic, Jurassic, and Cretaceous periods.
Mesozoic Era
The Paleozoic precedes the Mesozoic. And our current era, the Cenozoic, follows the Mesozoic.
It really wasn't an era. An Era was a much longer period of time. It was called the "Jurassic Period".
The Mesozoic Era is known as the Age of Reptiles.
