Found in Parker, Colorado. From what I understand, most pet wood around here is conifer, 55 million years old, Dawson Formation. Palm can be found in the area but is less likely. This piece is not the prettiest chunk of petrified wood I've found but it caught my eye because of the spotted look. It's the only piece I've ever found with these spots. Did I find a piece of palm wood, or is there something else that would cause a spotted look? (Entire piece is about 5 inches long, I only photo'd the nicer bits that show wood detail. The other half is junky looking.) Thanks!
