During the Permian era the Continent Pangaea was formed, it lasted from 299 to 251 million years ago and was the last period of the Paleozoic Era.

During the Permian period new types of plants and seven reptillian species were formed.

When you look at the marine life you see that the coral reefs were full of sponges and had a wide varriety of coral

Temperatures were cooler because the continent of Pangea was moving northward. Mountains were forming as the supercontinent Pangea moved. When the continent of Siberia collided into the northern part of Euramerica, Pangea was complete. The Ural Mountains were pushed up by this collision. http://www.fossils-facts-and-finds.com/

The changing climate affected how animals were evolving also. Amphibians that had depended on the swamps for a moist habitat began to die out. They were replaced by the reptiles whose bodies could live in the very dry air and the wide changes in temperature.

Permian Extinction

The corals were not the only species to become extinct. The Permian Extinctionwas largest mass extinction that had ever occurred. No extinction since has killed so much of the life on the planet. In the seas, 90 to 95 percent of the species went extinct or were severely harmed. On land the damage was less severe, but some species, like the pelycosuars, died out completely.

Two important groups of animals dominated the Permian landscape: Synapsids and Sauropsids. Synapsids had skulls with a single temporal opening and are thought to be the lineage that eventually led to mammals. Sauropsids had two skull openings and were the ancestors of the reptiles, including dinosaurs and birds.
