Exploring Fossils: Petrification

The video explains how a high, dry desert was once a flood plain with streams and large trees. These trees were preserved through petrification, a process where cells are replaced by minerals, turning them to stone. This preservation is so detailed that growth rings are visible. Petrification also affects other materials like shells and bones.
