That is one mighty old door stop! :-)
Interesting but what does it mean?
Thanks go out to a FReeper who shall remain nameless, and sent the link in FReepmail.
The public service announcment is, “even you can’t prevent this forest fire.”
Could it be from a lightening strike?
lol
Not even a T-Rex can pee it out
Yeah, I want one. I’ve got an older object I *could* use (meteorite, circa 4 billion years), not much chance of damage (except to the door) — but then, I keep the place buttoned down anyway, no need for a doorstop.
You have a meteorite? Very Cool!
I’ll give you 50 bucks for it.
Thanks, it’s a family heirloom, and will stay that way.
The Prof can except the NPS/BLM/FS SWAT Teams to come through his front door at 0430hr Monday to collect the rock!
I have my doubts that the cause of the fire can be figured out, but it does kind of figure that the natural causes of forest fires probably haven’t changed much.
Now we just need a bridge stone...
Wasn’t there a Dino skeleton that had identifiable lightning damage?
;’)
I’m a little hurt that no one noticed that last sentence in the excerpt...
Dino with cancer, never heard of lightning scar though.
Foggy mists of memory says that something like that was suspected.
Oh well, I’ll probably go nuts looking for it now.

So many unlikely things have to happen to make petrified wood, it is amazing that there is any of it around. We went to the petrified forest out near Holbrook, Arizona last month and in the crystal forest section there are huge trunks and section of logs laying around everywhere. It’s a wonder there are any left, because apparently before the national park was established passenger trains used to stop nearby and people would loot the area as much as they wanted. In a business near the park we saw a 30”x60” table with a large slab of petrified wood inset in the top that was selling for $26,000.00.
