4.3" Polished Petrified Wood (Arucaria) End Cut - Amarillo, Texas

This is a 4.3" wide polished, end cut of Upper Triassic petrified wood from a rather unusual location. It was collected from the Dockum Formation, south of Amarillo Texas. One end has been polished and the polished face is 4.3x4" This comes from a large collection of petrified wood I recently bought which includes some rare types from unusual locations.
