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.
An era is a span of time, so there was no era at that time. It was, however, the end of one era and the beginning of another. More specifically it was the end of the Mesozoic and the beginning of the Cenozoic.
The Age of Reptiles occurred during the Mesozoic Era. This era is subdivided into three periods: the Triassic, Jurassic, and Cretaceous. The Age of Reptiles was characterized by the dominance of dinosaurs and other prehistoric reptiles.
