Those are some sweet prehistoric finds that you have there. I don't know if they bring big $$'s in that shape or not, but I know that they can be cut into smaller pieces and then polished to really bring out their color and shapes. They are a nice item. Nice finds. HH
I live in Arkansas and around 100 million years ago these mountains were a shallow sea which was abundant in sea plant and animal life. This is pieces of one of those plant like creature. They looked like a tree with a main column and then branching out. They are quite collectable. Thanks Ray
