I found a group of leaf fossils, could not resist them. I know they are from the Green River formation of Utah; Eocene age. Are these Cuercus petros? I've looked over a lot of specimens from that area; these SEEM to match. (Except for the first photo.... not sure WHAT that one is! Leaves.... but from what?) I think I am developing a plant fossil obsession!
On another note - While I LOVE to hunt fossils, I DO buy specimens, so that I have an in-hand model to use for comparison and learning!!!!
