Beautiful specimen from the famous Petriefied Forest in Holbrook - Arizona - USA
The area south of the Colorado Plateau has been a national park since 1982. Park rangers monitor the millions of visitors every year to ensure that no one is taken away.
Colorful, over 200 million years old silicified piece of an araucaria with bark parts.
Dimensions: 10 x 10 x 7 cm Weight: 720 g
Google: www:Petrified-Forest-Nationalpark -Wikipedia.....very interesting and informative.
I bought a party with a few hundred kilos about 15 years ago. The material was salvaged in the Petriefied Forest around 1960 and "forgotten" on a farm in Nevada. Unfortunately, there are only a few pieces left.
