The Middle Permian, also known as the Guadalupian, was a geologic period that existed with in the Permian Period.

ClimateEdit

During this time of the Permian period, the climate became warmer and milder, the glaciers receded, and the continental interiors became drier. Much of the interior of Pangaea was probably arid, with great seasonal fluctuations (wet and dry seasons), because of the lack of the moderating effect of nearby bodies of water.

Terrestrial lifeEdit

About the middle of the Permian there was a major transition in vegetation. The swamp-loving lycopod trees of the Carboniferous, such as Lepidodendron and Sigillaria, were replaced by the more advanced conifers, which were better adapted to the changing climatic conditions.

Reptile and amphibian faunaEdit

The Middle Permian was dominated by primitive therapsids such as the dinocephalia.

Another group of therapsids, the therocephalians (such as Trochosaurus), arose in the Middle Permian. There were no aerial vertebrates.
