OK here is the story.
There was a very large granite bolder on my property and it had resisted many attempts to move it but finally someone brought in a bulldozer big enough and it was moved to a more convenient place. In the process of moving it a large fossil was exposed. It was notable for the many hexagonal structures which looked like a bee hive. Everyone agreed it was very curious and obviously a fossil but not more than that. I wish I had a piece of it but the whole thing would have weighed 50 pounds or more.
Many years later I was watching a program about ground nesting wasps and hornets. When I saw that the light went off. That was a fossil hornet nest. How long would it take to fossilize something like that? Could it have been under that large bolder, had the entrance blocked off and been sealed off long enough to fossilize?
