Mesozoic Era

Monday, September 17, 2012

The Mesozoic is the fourth of five geological eras in the Earth history time spans. It stretched from 220 million to 70 million years ago and is divided into three periods; the Triassic, Jurassic, and Cretaceous. The Mesozoic era is characterized by intense volcanic activity, the presence of marine and land reptiles and dinosaurs, and the abundance of conifer trees. During this time, the continental drift took place as today's continents began to separate from one another.
