8.7" Very Rare, Petrified "Snakewood" (Mennegoxylon) Slab - Texas

This is a rare, 8.7" petrified Snakewood (Mennegoxylon) slab from the Yugua Formation of Texas. It is polished to a matte finish on one side to highlight the unusual grain of this wood. This specimen has a repaired crack near the edge.

Snakewood (Mennegoxylon) is so named for the appearance of its cell structure. When viewed in cross section, it has the appearance of snake skin. It is an extinct genus of flowering plant from the same order (Caryophillales) as cactus, carnations, and beets.

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.
