8.3" Triassic Petrified Wood (Woodworthia) Slab - Arizona

This is a gorgeous slab of fossilized Woodworthia wood from the Chinle Formation near Winslow, Arizona. Woodworthia is one of the more uncommon types of petrified wood within the petrified forests of Arizona. The slab is 8.3x6.3" and is an end-cut from the log so that it varies in thickness up to about 3/4" It comes with an acrylic display stand.

The rich coloration is due to the contaminating minerals in the silica which replaced the original wood structure. For example pinks and reds are due to hematite, a form of oxidized iron. This is similar petrified would which is found in the Petrified Forest National Park. The petrified forest encompasses nearly 100k acres and this wood comes from land outside of the park.
