The temps are hovering just above 0°C. right now and there were snow showers predicted yesterday. Nevertheles, my wife noticed that I was beginning to show symptoms of cabin fever, so she just mentioned casually that I could take off if I felt like it. So I did. The Wutach is no place to hang out if snow is on the way, so I thought I'd take a chance with the Danube Valley again. There was a bit of snow in between, but just light sleet showers which were really no bother and none of it stayed on the ground, so digging was no problem. I didn't fancy the idea of bailing out the hole in the divisum zone again, so I walked down the ditch to my excavation in the hypselocylum zone and spent about 6 hours breaking rock. At the end of the day I was quite pleased with the spoils. I'm pretty sure that there should be some nice ones this time. I spent most of the day today cleaning up most of them with the stylus and tomorrow I'll be getting down to abrading them. Here's a photo of the ones I've done so far, which is already the majority of them. Still just a few smaller ones to remove from the matrix.

Maybe some of you remember way back a few years ago when I started reporting on my adventures in the ditch at the side of the road in the Upper Danube Valley. At that time I was excavating the Kimmeridgian divisum zone, but after a couple of years the digs got so close to the cliffs that it was time to leave it in peace. Since then I've been digging in the hypselocylum zone, which is deeper and far enough away from the cliff to be completely safe to work. There is however still one safe spot in the divisum zone that I keep walking past and thinking that I should have a go at it someday, but it's covered with such a large amount of overburden that I can't be bothered. Up until now. I've managed over the last couple of years to recover most of the available species from the hypselocylum zone, with the exception of a couple of extremely rare ones, and that's the main reason I keep on digging there. But I just needed a change today, so I thought I'd finally try my luck at that safe spot. We'd had quite a bit of rain over the past week, so I ended up using a lot of the overburden to build a dam and sluices in order to drain away the water which had accumulated directly at the place I wanted to dig. This took at least an hour, but it did the job, and I could get down to it. Here are a couple of shots I took after I'd spent a few more hours working at the exposure. As you can see, it was quite a muddy matter Thank goodness my wife does the laundry without complaint. It turned out to be well worth the effort. Here are my finds of the day. Now I can hardly wait to get to work on them, particularly that one at the top. I'll keep you posted on that.

ø 12.5cm. divisum zone Early Kimmeridgian Lacunosamergel Formation Sponge Facies From the Upper Danube Valley -
I visited the Kimmeridgian ditch again this week and just finished prepping the finds. I didn't do too badly this time, I'd say. Parataxioceras sp. & Ataxioceras hypselocylum on matrix. 16x12cm. Involuticeras involuta with a Pseudolimea sp. bivalve ø7cm. Laevaptychus obliquus with a small Glochiceras sp., an even smaller and pyritized Aspidoceras sp. and a sponge. 7x7cm. Two more Laevaptychus obliquus, parts of the jaw from Aspidoceras ammonites. Both are 5cm. long. Taramelliceras compsum. ø7cm. Aspidoceras sp. phragmocone with part of the living chamber. ø14cm.

It's become a regular habit for me to visit the site in the Kimmeridgian in the ditch at the side of the road at least once a month. For one thing, it's less than an hour's drive away and it's also relatively easy to work for an old codger like myself. No forging through the woods, clambering uphill and breaking hard rock. All I have to do is get out of the car and mosey a couple of hundred yards down the road and into the ditch. The marley limestone is easy to take apart, and as long as the hypselocylum zone is giving up its offerings, I'll be happy to keep on visiting it regularly. You just have to love the Upper Danube Valley, not only for the fossils, but also purely for it's majestic scenery. I thought to take my camera along today, so I was able to take some shots as I was working away. Spent about 4 hours there and I hit a good spot. Here's the first find after just about 20 minutes. Then they were popping out fairly regularly for the next few hours. Here are a couple of "discovery" and "breaking out" pairs of photos.

I spent another day at the Kimmeridgian site in the Upper Danube Valley near Beuron the other day. I had taken my camera along in order to take some shots, but I ended up making so many good finds that I forgot to get it out. Sorry bout that. One great thing about this location is that the finds are easy and quick to prep, so at least I can show you some of the finds. Aspidoceras sp. Ataxioceras (Parataxioceras) lothari Ataxioceras (Parataxioceras) planulatum Taramelliceras (Metahaploceras) nodosiusculum and Glochiceras sp. Ardescia perayense Ataxioceras (Parataxioceras) sp. Rasenoides lepidula

I hadn't gotten out to look for fossils for a couple of weeks due to commission work and other things, so I was beginning to itch so much that I spent the day yesterday digging away in my favorite ditch in the Upper Danube Valley where I've been working at prying up bits of the Kimmeridgian hypselocylum zone. It was a nice sunny day and relatively warm for the middle of winter, so it was quite an enjoyable experience, although my old bones were starting to ache a bit at the end of the day. Here are the things I've sorted out for the collection. Streblites tenuilobatus. 7.5cm. Parataxioceras perayense. 5.5cm. Eurasenia trimera and Glochiceras sp. 5x5x4cm. A sponge which may belong to the genus Hyalotragos sp.

Monday was the last time that I did a split shift before I'm headed off to full retirement at the end of the year, so as usual, I took advantage of the hours in between and headed off to the Kimmeridgian site in the ditch in the upper Danube Valley. Found a few nice things again this time. Well, winter is closing in, so I probably won't be back there again until the springtime now, but it won't be going away, since I seem to be the only collector that's interested in it. Lots of sponge amongst those ammos this time.

12cm. hypselocylum zone Kimmeridgian Lochen Formation Found near Beuron, Upper Danube Valley -
Over the years I've posted quite a few reports on my finds from the ditch in the Kimmeridgian in the upper Danube valley. Although it's over 40 miles away, I decided it was time to take a tour down there on my (battery powered) bike. It was a great trip, although I'm of course pretty tuckered out today. The site, or at least the exposures I was working, is pretty well cleaned out by now, but there is still a chance of finding another exposure in the next lower zone by moving on down the ditch and picking away. I have found a bit on the odd visit over the last year or so, but not all that much, since the preservation is mostly too soft and flatly pressed. This time I managed to find a spot where the matrix is more concretionary and harder, which heighten the chances of finding some better preserved fossils. I only spent about an hour and a half there, but this time some nice things came out, so I didn't mind the bit of extra weight on the return trip. I guess I'll be going back there again soon, but next time with the car Taramelliceras sp. Bathrotomaria sp. gastropod with 3 Streblites tenuilobatus ammos. Could have repaired it, but I decided to leave it as is. Streblites tenuilobatus Rasenia sp. PS. Here's the bike.

2 Garnierisphinctes sp. ammonites along with a number of small sponges and some shell bits. 12x8x4cm. From the divisum zone, Kimmeridgian, Lacunosamergel Formation in the upper Danube valley. -
Calcite mold. Complete specimen. Only the apophyse is missing on this microconch. C. divisum is generally larger than C. crusoliense, which reaches an adult diameter of at the most 15 cm. The bipartite ribs crossing the venter continue mostly on until the end of the bodychamber and can become irregular, whereas by C. crusoliense they tend to merge towards the end and remain relatively constant.
