10.1" Tall, Triassic Age, Petrified Wood Bookends - Arizona

This is a gorgeous pair of bookends made from Late Triassic aged, Arizona petrified wood. The bookends have been polished on the outer face and have white and brown coloration. There is even a green crystal filled pocket within each bookend, however the composition of this mineral is unknown. Exceptional polishing work on this pair.

Each bookend slightly varies in size, with one measuring 10.1" tall, 8.2" wide and 1.7" thick, while the other is 9.8" tall, 8" wide and 1.75" thick.

Petrified wood is the name given to wood that has been turned into stone (fossilized) through the process of permineralization. All of the organic matter becomes replaced by minerals, while much of the original structure such as tree rings in retained. For this to happen the wood needs to be buried in an environment both low in oxygen (preventing decomposition) and with flowing, mineral-laden water. The coloration is due to the various minerals that are present during fossilization. For example red colors are due to iron compounds, greens due to copper, etc.
