What animals died in the permian extinction.

Abstract. The most severe mass extinction among animals took place in the latest Permian (ca. 252 million years ago). Due to scarce and impoverished fossil floras from the earliest Triassic, the ...Sepkoski’s ground-breaking statistical work showed abrupt ocean-wide changes in biodiversity about 490 and 250 million years ago, corresponding to two mass extinction events. These events divided marine life into what he called “three great evolutionary faunas,” each dominated by a unique set of animals. But the new model reveals a fourth.The Permian-Triassic extinction, also known as the Great Dying, refers to a time 252 million years ago when 90% of marine species and 70% of terrestrial species died out. Occurring at the end of ...The standard for separating the tail end of the Permian from the start of the Triassic is based on a marine fossil bed near the city of Meishan in southern China. Its sediments point to a catastrophic moment 251.96 million years ago (give or take 35,000 years or so) when aquatic ecosystems collapsed and around 96 percent of all ocean species died out.

The trilobites may have gone extinct (along with 95% of marine species) during the mass extinction at the end of the Permian period, but that doesn’t mean that they were a failure.
