Although scientists had previously hypothesized that the end-Permian mass extinction, which took place 251 million years ago, was triggered by voluminous volcanic eruptions in a region of what is ...Permian Period - Fossils, Extinction, Climate: Permian rocks are common to all present-day continents; however, some have been moved—sometimes thousands of kilometres—from their original site of deposition by tectonic transport during the Mesozoic and Cenozoic eras. For example, Permian glacial terrestrial and marine deposits typical of the cold high …The Permian–Triassic boundary (PTB, ~252 Ma) crisis was the most severe mass extinction episode in Earth history. It is now widely accepted that the ultimate trigger of this crisis was eruptions of the Siberian Traps Large Igneous Province (STLIP), based on temporal correspondence demonstrated by high-resolution zircon U-Pb dating.

The Triassic Period was a critical time for marine vertebrate evolution and ecology, with important groups appearing in the aftermath of the End-Permian mass extinction (Scheyer et al. 2014), and ...appeared in the Late Permian, and only one or two lineages survived the end-Permian mass extinction, with stem group representatives of all four suborders appearing by the end of the Triassic.

At the beginning of the Permian period, the Earth was still in the grip of an ice age. However, the period ended in quite the opposite manner.
