New analysis sheds important light on an ancient mass extinction event
(PHYSorg.com Archaeology & Fossils)
 


The end-Permian mass extinction is considered to be the most devastating biotic event in the history of life on Earth-it caused dramatic losses in global biodiversity, both in water and on land. About 90% of marine and 70% of terrestrial (land) species went extinct. This event may have been responsible for opening up niche spaces that ushered in the age of the dinosaurs. We know that the end-Permian in the marine realm happened about 251.9 million years ago-but the age and duration of the extinction on land, and whether it coincided with the marine extinctions, is one of the most hotly debated topics in palaeontology.
