4" Cretaceous Petrified Palmwood Round - New Mexico

Petrified palmwood includes a group of fossil woods that contain rod-like structures within the regular grain of the silicified or agatized wood. Depending upon the angle at which they are cut, these structures show up as spots, tapering rods, or continuous lines. The rod-like structures are sclerenchyma bundles that comprise part of the woody tissues that gave the wood its vertical strength.
