The Paleozoic Era ended with the largest mass extinction in Earth's history, the PermianâTriassic extinction event. The effects of this catastrophe were so devastating that it took life on land 30 million years into the Mesozoic to recover.Recovery of life in the sea may have been much faster.he Cambrian spans from 541 million years to 485 million years ago and is the first period of the Paleozoic and of the Phanerozoic Eon. The Cambrian sparks a boom in evolution in an event known as the Cambrian Explosion in which the largest number of creatures evolve in the history of Earth during one period.
The Paleozoic Era, meaning ancient life is the first of three eras that form a part of the Phanerozoic Eon, the other two periods being the Mesozoic and the Cenozoic. The Mesozoic is the age of the Dinosaurs and the Cenozoic is the era in which we now live.The Paleozoic Era spanned a longer period of time, from approximately 542 Ma to 251 Ma. Just as the Mesozoic is divided into periods (Triassic, Jurassic, and Cretaceous), the Paleozoic Era is also divided.nimal Life. The beginning of the Paleozoic era is marked by a sudden explosion of invertebrate animals, over 900 recorded species in the Cambrian period. It was only a few million years later that vertebrates appeared during the Ordovician period.
