Petrified wood is far more than a paleontological curiosity; it acts as a high-resolution geological recorder. A research team led by Dr. Steffen Trümper from the University of Münster has revealed that mineralized wood can serve as a natural archive, documenting how sedimentary basins sank and shifted over 300 million years.
Five stages of mineralization
The study, focused on specimens from the Kyffhäuser Mountains in Germany, identified five distinct generations of silica. Each phase crystallized under different chemical and thermal conditions, creating a chronological stack that spans from the late Carboniferous to the Early Cretaceous. This sequence provides an unprecedented timeline of geological change preserved within a single biological structure.

From Pangaea's tropics to the deep crust
These ancient trunks, some measuring 20 meters, belonged to extinct conifer relatives that thrived in tropical dry forests on the supercontinent Pangaea. The research indicates these fossils were once buried between 3 and 5.5 kilometers below the surface, enduring temperatures up to 240 degrees Celsius. Such data is critical for understanding the development of the Central European Basin System, which remains vital for groundwater and geothermal energy exploration.

A global tool for continental drift
As detailed in Scientific Reports, this discovery transforms how geologists view fossilized wood. Because these formations exist worldwide, analyzing the stages of quartz replacement offers a new method to trace continental evolution and tectonic shifts in regions where traditional rock records are incomplete.
