What was the Permian period?

The

Permary period is the last of the six periods forming the paleozoic era, the oldest era of multicellular life on Earth, ranging from about 542 to 251 million years. The Permian period itself extends about 299 to 251 million years ago.

During the Permian period, all land masses, except in the East Asia, were aggregated to the supercontinent of Pangea. This minimized the number of available coastal stations and created temperature extremes, including the largest desert in the history of the planet: PANGEA. So much soil was promoted by large temperature extremes in general and the terrain hostile to everyone, in addition to the most unusual life. In the early period Permian appeared a carnivorous Reptile anteosaurus. In some respects, the animal resembles appearance. He had a long tail and weak limbs, suggesting a semi-aquatic lifestyle similar to a crocodile lifestyle. He also had a bone plate on the skull, suggesting that she was involved in the head of the head, probably for disputes over the territory. Hard shellthat developed in the earlier carbon period, allowed the tetraons to easily lay eggs on the ground without drying them.

The permic period opened with the Ice Age, but it became more and more and hot, until the end was the hottest era over the last 500 million years. Beetles and flies developed during the period period. The variety of plants and oxygen levels were high near the coast, where there were large swamp forests. The first fully earthly animals have evolved, including large herbivores and carnivores. Labyrinthodontia, animals that look like a mediation form between bony fish and crocodiles appeared.

The

Permian period ended in the extinction of Permian-Triassic Evojtranne, called the "mother of all mass extinction". 96% of the seabed and 70% of the soil genera were smoothed. 99.5% of individual organisms probably died. Like most old bulk demise we are sureI, what caused, although the impacts of asteroids, climate change, release of methane hydrate and volcanism were accused by various scientists.
