Hi all,
So I found this odd piece of petrified wood on Marrowstone Island in Washington state. I find petrified wood often on the beach here. This one has a dark band running through the specimen. The dark band is coal like except it has wood grain banding in it as well. The band is brittle and I broke off a few chunks and tried to burn them, and they do quite like charcoal. Now I also managed to get a small piece of the petrified wood to come off and it did not burn. I am positive the wood is petrified too, I have many samples of it I have found including one weighing over 60lbs.
