- Because Pangaea was so immense, the interior portions of the continent had a much cooler, drier climate than had existed in the Carboniferous.
What was the climate like? the polar regions were covered with deep layers of ice, the tropics were covered in swampy forests. Towards the middle of the period the climate became warmer and milder, the glaciers receded lack of nearby bodies of water. The drying tendency continued through to the late Permian, along with alternating warming and cooling periods.
What type of living thing inhabited the the earth?plants,gymnosperms,short palm,cycads and the gingko. Arthropods ,bugs, with mouthparts modified for piercing and sucking plant materials,cicadas and beetles.
On land, the giant swamp forests of the Carboniferous(the Carboniferous period or the system of rocks deposited during it) began to dry out. The mossy plants that depended on spores for reproduction were being replaced by the first seed-bearing plants, the gymnosperms.
Why did animals and plants go extinct? some, point to the evidence of casastrophic volcanic activity others think it could be glaciations because volcanic eruptions lead to a rapid cooling in global tempatures "nuclear winter"
Scientists estimate that more than 95 percent of marine species became extinct and more than 70 percent of land animals.
