The biggest mass extinction of all time, at the end of the Permian era 251 million years ago, wiped out the vast majority of species.Reef building sponges called stromatoporoids and corals suffered losses and stromatoporoids finally disappeared in the third extinction near the end of the Devonian. Brachiopods associated with reefs also became extinct. Groups of trilobites disappeared at each of the three extinctions and very few survived into the following Carboniferous Period.Permian Period, in geologic time, the last period of the Paleozoic Era, lasting from 298.9 million to 252.2 million years ago. The climate was warming throughout Permian times, and, by the end of the period, hot and dry conditions were so extensive that they caused a crisis in Permian marine and terrestrial life.This extinction apparently began about 50,000 years ago when humans moved into Australia and the Americas, causing the disappearance of many species. No one knows how many species currently exist on Earth. The best estimate is about 8.7 million, not counting microorganisms.
The extinction coincides with massive volcanic eruptions along the margins of what is now the Atlantic Ocean. 3.

Whatever happened during the Permian-Triassic period was much worse: No class of life was spared from the devastation.Geologists contend that Pangea’s formation seems to have been partially responsible for the mass extinction event at the end of the Permian Period, particularly in the marine realm.As Pangea formed, the extent of shallow water habitats declined, and land barriers inhibited cold polar waters from circulating into the tropics. This is thought to have reduced …The Permian (along with the Paleozoic) ended with the Permian–Triassic extinction event, the largest mass extinction in Earth's history (which is the last of the three or four crises that occurred in the Permian), in which nearly 81% of marine species and 70% of terrestrial species died out, associated with the eruption of the Siberian Traps. One of the most current theories for the mass extinction of the Permian is an agent that has been also held responsible for the Ordovician and Devonian crises, glaciation on …
Ordovician-Silurian extinction, global event that eliminated some 85 percent of all Ordovician species. It was driven by climate and habitat disruptions caused by the onset of glaciation in Gondwana, the associated fall in sea level, and a subsequent warming period which melted ice and brought about rising sea levels.
Instead, the scientists concluded that the extinction did not occur suddenly or simultaneously, suggesting that the disappearance of a wide variety of species was not linked to any single catastrophic event. ... nor is it the earlier End Permian extinction (aka “The Great Dying”) of 252 million years ago, nor is it even the slightly later ...August 28, 2015 at 2:00 pm.
