More Science, Please!
years ago when the Arizona desert was actually a tropical forest. I
was slightly disappointed to find that it's not a forest of standing
trees, but a plain littered with big chunks of petrified log bits. It
didn't stop me from dorking out, though... I have a soft spot for
ancient stuff. This guy was the biggest - it weighs 44 tons! The tree
was heavy, too, I think.
