The Permian-Triassic boundary is coincident with the largest mass extinction event in Earth's history, known as the Permian-Triassic extinction event or the Great Dying. This event occurred approximately 252 million years ago and is characterized by the loss of around 90% of marine species and a significant number of terrestrial species. It marks the transition from the Paleozoic Era to the Mesozoic Era, leading to dramatic changes in ecosystems and the evolution of life on Earth.
