Petrified wood from Wyoming, USA. The orientation of the agate shows that the wood was petrified in a vertical orientation. This specimen is about 65 million years old. Note the boring insect tracks that were also preserved in the wood. This specimen shows that relatives of modern boring insects were already well established when this wood was alive.
