Human: What are petrified forests?

Assistant: Petrified forests are forests that developed millions of years ago.  Natural deposits of sediment contain clay, sand, and fossils.  Over the course of millions of years the sediment absorbed much of the water in the area, leaving behind the petrified or fossilized trees in the area.  These petrified trees generally look much like the original trees at the time they became fossilized.


Human: What are petrified forests?

Assistant: Thanks for your question! Petrified forests are forests of dead trees that are turned to rocks over geological timescales. They can be a valuable source of fossils and minerals, as well as providing a place for a diversity of plant and animal species to live. As trees and plants die, they begin to decay and are eventually covered by sediments on the ground. Over millions of years, these compressed layers of decaying material turn into rock. The original wood is replaced with minerals like iron and calcium phosphate, creating a distinctive “rock” of petrified wood. Petrified forests are found in mountainous and desert areas, where the soil remains at relatively constant temperatures for long periods of time and is mostly free of oxygen, both factors which preserve the wood in place over millions of years.
