Click the Dimetrodon below to learn all about the climate and creatures of the Permian!
Two major events can help us better understand the rise and fall of the Permian. Click the flag below to learn more!
290 MYA-250 MYA47 million years longOccured at the end of the Paleozoic era, in the Phanerozoic eon.
- The Permian was the first time period to exist in the Pangea super-continent.
- The largest desert in all of geologic history formed in the Permian.
- The Permian-Jurassic extiction event is known as the Great Dying, as it was the largest mass extinction event.
The Permian saw the formation of deserts and glaciers within Pangea. The lower humidity allowed for all these new, more unforgiving ecosystems to form which resulted in complex and hardier creatures to fill in new niches! Reptiles and Synapsids (stem-mammals) split off, creating life that would be a little more familiar to us today.For xample, Gorgonopsids was a synapsid predator that looked more like a reptile than than an early mammal.
What was it like?
Carbonifourus Rainforest Collapse
252 MYA, an influx of volcanic activity combined with climate change drastically changed the planet. 96% of marine life, and 70% of terrestrial life was wiped out. This marked not only the end for the Permian period, but for the Paloezoic era as well.
Permian-Triassic Exctintion Event
240 MYA, the continents would rearrange themselevs to form Pangea. This causeda drastic drop in both humidity and globaltemperatures, since there was more landfarther away from the coast. The rainforests would make way to glaciers and deserts thatmarked the beginning of the Permian.
