Fossil Wood/Petrified Wood

This fossil wood is from the Triassic Period and is about 225 million years old. It was found in Madagascar. Trees fossilize under the right conditions, if they are covered by earth, sand, or volcanic ash before they rot. Water seeps through the covering earth and soaks into the wood. The water has minerals in it. Wood has many tiny holes. The minerals fill these holes and become solid after many millions of years. This is called petrification.
