Life During the Paleozoic. The Paleozoic Era is literally the era of “old life.”. It lasted from 544 to 245 million years ago and is divided into six periods. Major events in each period of the Paleozoic Era are described in Figure below. The era began with a spectacular burst of new life. The Mesozoic Era began 252 million years ago and lasted for almost 200 million years. This era is known as the “Age Of Reptiles” due to the dominance of this group of animals not only on land, in the shape of the dinosaurs, but also in the oceans and skies. The Mesozoic Era is divided into three periods; the Triassic, Jurassic and Cretaceous.
