What era was the Age of invertebrates?
Paleozoic

The Paleozoic has been called the Age of Invertebrates because of the rapid development of invertebrate animals during that time.

Reptiles evolved when amphibians adapted to life on land by developing a thick, waterproof skin and/or scales, and eggs that have leathery or hard shells and can incubate on land as well, not requiring the animal to live even part of its life in water.
