Up for sale is a piece of cut and polished petrified wood from Washington, USA. This specimen is from
an old collection that has been in storage since the 1970s. There may be some lacquer or tape on the
backside of the piece so see photos for details.
Here is some interesting information about petrified wood (from evolvingearth): Approximately 17.5
million years ago during the middle of the Miocene epoch, a series of large volcanic eruptions began in
the eastern part of the Columbia River Plateau, near the present-day borders of Washington, Oregon, and Idaho. Forests and swamps in the region were buried by lava flows and the trees were preserved by
silica dissolved from volcanic ash and the basalts. This happened several times during 10 million years of
volcanic eruptions, resulting in numerous deposits of fossilized wood across the Columbia Plateau.
Later, geologic uplift and erosion exposed some of these trees, which have been collected by amateurs
and scientists for nearly a century. When cut and polished, the specimens of petrified wood can be quite beautiful to behold.
We have a variety of fossils available so be sure to check out our other listings!
