The earth during the Mesozoic Era was very different than it is today. The earth was only one continent whereas today it is seven. This huge super-continent was called Pangea. During the Jurassic period Pangea was separated into two continents known as Laurasia and Gondwanaland, and during the Cretaceous period, the continents as we know them today began to appear. Just as in the future the continents we look much different as know them now.

Evidence show that at the beginning of the Triassic period, before the dinosaurs appeared, the global temperature of the Earth was averaged around 50 degrees to 60 degrees Fahrenheit. Although the end of the period the temperature became hotter and the humidity became drier. Desserts also began to appear. Ginkgo trees and fern forests began to appear in the Northern Hemisphere while close to the equator conifer forests and c

As the Triassic period unfolded, the therapsid assemblage declined and new animal life forms appeared. These were the first of the dinosaurs. Dinosaurs ranged from the size of a chicken or smaller to giants weighing tons. The dinosaurs thrived all over the world for about 150 million years. The most dominant dinosaur, especially in the later Triassic, was the prosauropds. They are known from the Triassic period and their bones are found all of the continents. They were a very successful life form because they could adapt to very many environments. They also have a very flexible posture and gait.

Lost in the shrubs and hidden at the Plateosaurus feet is a small, two legged, long- tailed animal named Podokesaurus. The only know specimen was found in rock exposures near the campus of Mount Holyoke College in Massachusetts. Although the specimen was destroyed in a fire over 5 years ago, replicas have been made of it today and the lost specimen is thought to have previously found and named Coelophysis. It is represented as one of the best known types of dinosaurs – meat-eaters or carnivores. After the Coelophysis or the Podekesaurus appeared,
