Ancient Arctic sediments revise understanding of wildfires in the Early Triassic
Berlin, Germany (SPX) Nov 18, 2025 Researchers have identified new evidence of ancient wildfires that alters established views on the Early Triassic epoch. An international consortium, including Heriot-Watt University in Scotland, found molecular traces of charred vegetation in sediments dating back roughly 250 million years. The research contradicts longstanding assumptions about a global charcoal gap following the Permian-Triassic extinction. For years, the scarcity of visible charcoal in geologic layers led scientists to believe ... read more |
