In preparation for a planned outing next week with my oldest son to hunt for fossils in the Lincoln Creek formation, I went to an outcrop of the local Blakely formation this afternoon, and now that I'm primed to spot concretions, I saw a few right away. I only grabbed one to bring home (just had a small bag), but I may go back and grab some more later. Since I lack the proper tools to prepare a fossil that's in a concretion (at least for now!), I just used my trusty hammer. I'm not really seeing any fossil remains here, but it does have a really interesting funnel shaped part coming out of one side. Maybe it's some kind of burrow that later filled with different sediment? Or just purely geological? There's also a lot more of the center bit to expose, but I didn't want to keep whacking once it shattered, since I'll probably just destroy any fossil remains that are in there. Anyone have any thoughts on this? Should I try to whack it one more time? Toss it? Secure it back together and save it for another day?
