Mass extinctions are major losses of biota, typically marked by the loss of 10% or more families and 40% or more species, in a geologically short time. Up to 90% of marine species disappeared from the fossil record, with many families, orders, and even classes becoming extinct. One major event happening in the Permian Period was the beginning of the Reptiles and the break up of Pangea. The Silurian Period occurred from 443 million to 416 million years ago. The Permian-Triassic extinction killed off around 96 percent of all marine species and about 70 percent of land-dwelling species. The Early Permian Epoch is the most ancient, followed by the Late Permian Epoch. The Triassic Period began 251.9 million years ago (Mya), at the end of the Permian Period.
