6.25" Polished Cretaceous Petrified Wood Round - Texas

This is a beautiful, 6.25" wide petrified wood round from the Woodbine Formation, collected in Tarrant County, Texas. It's Late Cretaceous (Cenomanian Stage) in age, or approximately 95 million years old. It has been cut into a slab and polished to a glossy finish on both sides to highlight the incredibly well preserved wood grain detail.

It comes with an acrylic display stand.

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