I mentioned in another post a few days ago that I had discovered a site in the Middle Jurassic Aalenian which I hadn't visited previously. I found it rather unexpectedly while in search of the humphriesi oolite formation. It was obvious that other collectors had worked here in the past, but the rock had also been weathering away for a few years since the last ones were here, so I figured it would be worth spending the good part of a day inspecting it. I set off to this avail this very morning. It's a bit of a way up to get there, but not too strenuous if you take your time. By the way, I remembered to take my camera along this time, so here's a shot of the exposure. I spent about 5 hours working at it but ended up digging out a lot of partials since the stone was extremely hard at the one productive horizon and too soft in the other one. That's the luck of the game sometimes. You can always find the right horizon once you've located an exposure, but the preservation is often quite different than at other exposures not too far away. Here are pics of the 2 spots I was working at. It wasn't all for nothing at least, since I did manage to salvage a good sized Staufenia staufensis ammonite out of the hard horizon. This is how it looked before I maneuvered the 2nd block out of the bank. And here are both pieces ready for transport. Looks like I've got a bit of prep work ahead of me. There were also a few smaller ones to take with me. So that was it for the day. Downhill is always as easy as pie and a stop on the way home for a rump steak with scalloped potatoes and a red bull is the incentive that gets me out in the first place I'll post the finds later on once I get down to prepping them.

This past Sunday, I decided to pay my friend a visit at his workplace in the Wutach valley which I reported on recently. I left home a few hours earlier than he did since I wanted to visit a site on the way which another friend had told me about. This was off of a steep path through the woods which I had never taken before, so I was looking forward to excercising my calves and thighs. The way took me a kilometer or so uphill until I reached what appeared to be the pinnacle, which was where the exposure in the humphriesianum zone was supposed to be which I had been looking for. Up to that point I had hardly noticed any exposures, so I was happy to discover an approximately 20 meter long one here just below the path. Downed the knapsack, pulled out the tools and went at it. After a few minutes, however, I noticed that I obviously hadn't reached the highest point, since I was digging in the Aalenium, the epoch where I feel most at home, so it works like a magnet on me. Surprise, surprise. Funnily enough, I ended up making my best finds here. Spent about 2 hours prying away at well-weathered rock which obviously had not been touched by collectors for a good long time. I think I'll come back soon for another visit. Anyway, I carried on afterwards up the hill and eventually found the exposure I had been originally looking for. Spent an hour or so exploring it, but didn't come up with any ammonites as I'd been hoping. Did find a nice bivalve however. After I was done there I headed on over to my friend, a brisk walk of a couple of kilometers through the woods over flat land. Just a bit of downhill slipping and sliding at the end to get to him. Good thing I could hear him hammering since it wasn't all that easy to orientate myself for all the trees and shrubs. Then I just relaxed, drank a lot of water and watched him sweating at it. He'd had enough after an hour or so, so we made our way together down to his car and he drove me back to mine, which was a welcome relief for me. Here are the finds I made, already prepped and finished. The first is a Ludwigia haugi, my avatar, the next ones are Ancolioceras opalinoides and finally the bivalve from the humphriesi oolite, a Ctenostreon proboscideum.

I took another trip to the Wutach yesterday and dug up the Aalenian a bit. Didn't find all that much this time around, but I was happy to have found another Ludwigia haugi in the murchisonae zone which went straight into the display case after prep.

I made another visit to that site in the Middle Jurassic Aalenian to continue on where I'd left off last week. Here's the original report . I headed back up to the exposure with the intent of continuing along removing more of the weathered blocks from the bank. But first of all, I noticed a possibility to remove a bit more overburden from my dig last week. Like I'd mentioned before, this overburden belongs to the so-called staufensis bank and there's always a chance of finding something in it, although they are few and far between and not always complete. But waddayaknow! I uncovered a Staufenia staufensis ! You can't see it all that well in the first photo, since most of it is still inside the matrix, maybe a bit better in the second one. I had just dug out the missing piece of the venter and took another shot. I banged around a bit more, but soon gave up when the going got too tough. Then I turned my attention for about half an hour to scraping away the dirt and rubble in front of the weathered blocks. Then I started hammering and prying out the blocks, starting as usual at the top. It didn't take long this time before the finds started showing themselves.

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.
