[Dr Steffen Trümper of the University of Münster] led a study published in Scientific Reports that uncovered evidence revealing parts of what is now central Europe were buried up to 5.5 kilometers beneath Earth's surface at temperatures reaching 240°C (464°F) over hundreds of millions of years, near the Kyffhäuser mountains in Germany. The research involved analyzing fossilized tree trunks dating back over 300 million years. These findings provide a significant new tool for understanding geological history through fossil records and reveal evidence of tectonic movements and continental evolution preserved within these ancient wood fossils.
