Question

Mesozoic era is called era of creepers,why?

Answer 1

Creepers means Reptiles, and the Mesozoic Era is referred to as the period of reptiles because during this time period the dinosaurs dominated the lands, and pterosaurs dominated the skies.

The oceans were dominated by crocodylians, and other marine forms of repltiles.

Since all these animals were some forms of reptiles, thus the Mesozoic era is called so.
