The Latest Permian Mass Extinction (LPME) was the largest extinction event in Earth's history to date, resulting in the loss of between 80-90% of life on the planet. Despite extensive research, the exact cause of the dramatic changes in climate during this time remains unknown. A team of internat
The Permian-Triassic mass extinction, also known as the Great Dying, was the largest mass extinction in Earth’s history. It occurred about 252 million years ago and wiped out about 90% of marine species and 70% of terrestrial species.
In the case of the LPME, it is widely accepted that the rapid warming associated with the event is linked to massive volcanism occurring at a huge deposit of lava called the Siberian Traps Large Igneous Province , says Frank, but direct evidence was still lacking. Frank explains there is a continuous record of the earth’s history contained in sediments in marine environments which acts almost like a tape recorder because deposits are quickly buried and protected. These sediments yield an abundance of data about the extinction and how it unfolded in the oceans. On land, it is more difficult to find such well-preserved records from this time period.
Shen was able to analyze the mercury isotopes in the samples and tie all the data together says Frank.
