Just as minerals can seep into an animal’s remains and preserve its shape, fossilized wood is an impression of a tree in life, rendered in stone. Petrified trees are unique specimens that capture more details of prehistoric plants than other fossils. This is because they are fossilized at a cellular level, whereas most other fossils are impressions of plants on soft earth. These particular specimens are sliced and polished to give a high-definition cross-section of the amazing colors and patterns within!

This specimen is a 1.81" slice of petrified wood from Arizona. It includes a specimen card, which also serves as its certificate of authenticity.
