The Permian is a geologic period and system which extends from 298.9 to 252.17 million years ago. It is the last period of the Paleozoic, following the Carboniferous and preceding the Triassic of the Mesozoic. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the ancient kingdom of Permia.
The Permian witnessed the diversification of the early amniotes into the ancestral groups of the mammals, turtles, lepidosaurs and archosaurs. The world at the time was dominated by a single supercontinent known as Pangaea, surrounded by a global ocean called Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior.Amniotes, who could better cope with these drier conditions, rose to dominance in place of their amphibian ancestors.
The Permian (along with the Paleozoic) ended with the largest mass extinction in Earth's history, in which nearly 90% of marine species and 70% of terrestrial species died out. It would take well into the Triassic for life to recover from this catastrophe. Recovery from the Permian-Triassic extinction event was protracted; on land, ecosystems took 30 million years to recover.

New Permian fauna from tropical Gondwana. Juan C. Cisneros et al (2015), Nature Communications http://dx.doi.org/10.1038/ncomms9676 Terrestrial vertebrates are first known to colonize high-latitude regions during the middle Permian (Guadalupian) about 270 million years ago, following the Pennsylvanian Gondwanan continental glaciation. However, despite over 150 years of study in these areas, the biogeographic origins of these rich communities of land-dwelling vertebrates remain obscure. Here we report on a new early Permian continental tetrapod fauna from South America in tropical Western Gondwana that sheds new light on patterns of tetrapod distribution. Northeastern Brazil hosted an extensive lacustrine system inhabited by a unique community of temnospondyl amphibians and reptiles that c...
""Nyctiphruretus"" is an extinct genus of nyctiphruretid parareptile known from the Guadalupian series of European Russia. Many fossils of the type species, "N. acudens", were found well preserved near the Mezen River of European Russia in various stages of growth. The dentition identified that "Nyctiphruretus" is a herbivore. Based on the large numbers of individuals found and the sediment that they were found in, it appears that their diet consisted of aquatic plants. Adults discovered averaged 36 cm in length with a 4.4 cm skull that was crushed but recognisable. "Nyctiphruretus" was first named by Efremov in 1938 and the type species is "Nyctiphruretus acudens". In 2002, a second species was named by V. V. Bulanov. "N. optabilis" is known from a single jaw, also from Russia, Ea...
