Mesozoic Era BY: Jordan Thompson

Time This Occurred Occurred from 245 million years ago to about 66.4 million years ago. It took place between the Paleozoic era and the Cenozoic era which is the era we are living in. It was the third era that occurred.

Climate The temperature was hotter on land and on water than it was during the Paleozoic era. The weather was more tropical. Because of this the seas were lower causing different types of land structures for life to deal with. This era was dryer than the Paleozoic era.

Life Recovering From Permian Extinctions Took most of the Mesozoic era; the Triassic and Jurassic periods for the diversity of the species to repopulate and gain some balance. The plants survived the extinction better than the animals, new types of plants formed to survive the changing conditions.

Rise of Reptiles and Dinosaurs The dominant land animals at the end of the Permian periods were the Synapsids which was characterized by having a single hole on each side of the skull behind the eye. Sometimes called mammal like reptiles. The animals that developed in the Mesozoic period had to develop new bodies to survive the extremes of temperature and moisture.

Rise of Reptiles and Dinosaurs Reptiles adapted better to the warmer dryer conditions. Reptiles developed thick, leathery skin on their bodies and their eggs. These dominated the land in both size and numbers. The dinosaurs evolved from the reptiles. During the Jurassic and cretaceous periods dinosaurs ruled the earth.

Mass Extinction Occurred at the end of the cretaceous period. This brought the end to the dinosaurs and tropical forests. Researchers say that an asteroid brought the end to the Mesozoic era.
