Long before the dinosaurs, at the end of the Permian Period, something triggered Earth's most profound mass extinction and reset the evolution of life on this planet.Abstract: Wildfire has been implicated as a potential driver of deforestation and continental biodiversity loss during the end-Permian extinction event (EPE; ∼ 252 Ma). However, it cannot be established whether wildfire activity was anomalous during the EPE without valid pre- and post-EPE baselines. Here, we assess the changes in wildfire activity in the high-latitude lowlands of eastern ...
