I mentioned in this thread that I would be taking my camera along the next time I go on a hunt to the Wutach Valley, and believe it or not, I actually remembered , so I figured I might as well take you all along for the trip. The goal is exposures of the murchisonae and bradfordensis zones in the middle Jurassic Aalenian layers, which are accessible on some forested hills in the viscinity. Prime finds are ammonites with some bivalves with some other fauna occasionally strewn amongst them. The first thing to do is to drive your car up a dirt road and then park it on a meadow with permission of the local farmer. Then you get your gear out of the car, head uphill over another meadow..... ...and duck into the forest. If you happen to have your camera with you, then you start taking photos of the forest flora.

I decided to try my luck again at one of my old Aalenian spots in the Wutach valley last week and it panned out this time. I'd been there a couple of weeks ago without much success, so I decided to try to follow the horizon this time in the hopes of finding a pristine exposure. This necessitated a lot of digging and delving, and was a bit of a challenge for my sense of orientation, but I finally was able to localize two exposures which look like they could be producing some interesting finds for some time to come. I've been busy the last few days doing some commission work, but I finished that off this afternoon, so now I can get down to working on these finds. Here's what I brought home with me. At the bottom left of the second crate is a larger ammonite which I managed to get done quickly today since there wasn't much matrix at all to remove. Here's the finished product. Staufenia discoidea? 12cm. More to follow as time goes on.
