Explorando fósiles: petrificación

The video explains how a high, dry desert was once a lush plain with streams and large pine trees. Over 225 million years ago, these trees were preserved through petrification, a process where organic cells are replaced by minerals, turning them to stone. This process is so thorough that even growth rings are visible. Petrification can also preserve other materials like shells and bones.
