Top Trilo Posted August 7, 2021 Share Posted August 7, 2021 I found this piece of late Cretaceous petrified wood in the Dawson formation of Colorado. Most of the piece however is this grey ash colored rock and I was just wondering, 1. What type of rock is it? I’m willing to do tests such as scratch and hardness if it will help. 2. How was it formed? 3. When was it formed? Did it form during fossilization or much more recently?

Solidified volcanic ash would & does provide silica & other minerals that can fossilize wood. That piece could be part of a limb cast. Then again, I could be way off base.
