  1. I guess as you get older, you get a little more crazy. I had sworn to slow down a bit, particularly after my exhausting hike down the mountain recently, so I'd been visiting easy-to-work sites like the ditch and the shark tooth exposure the last few weeks. But then my colleague told me that he'd opened up another section at the Callovian site in the Wutach Valley and that I should have a look at it. Maybe you can make some good finds. Well, why not? So off I went today. At this site you have to remove a lot of overburden to get at the good horizons and then you're whacking away at a hard concretionary sandy limestone in search of fossils. I use a pick hammer and club hammer for those purposes, which makes for a bit of wear and tear on the old tendons. The first 3 hours were not all that productive for my liking. Here's what my efforts had produced up to that point. But then I finally stumbled on something interesting and quite large to boot. The photos above were taken after about an hour of overburden removal. I needed yet another hour to remove the rest, which was absolutely necessary, since the ammonite was resting in the middle of an extremely hard concretionary lager and the chances of breakage were high. I was also already pretty sure at this point that the outer whorls would not survive the treatment, since they appeared to be unstable. Here's how things looked towards the end. You can see where the outer whorls have broken off and after I was able to pry out the inner whorls, I could see that the outer whorls didn't continue around to the back, since those parts were already eroded away. So that wasn't too bad after all and the inner whorls appear to be well-preserved as you may be able to discern below. ø is 16cm. So after this action, my heart was happy, but my wrist was aching like crazy and my legs were about to collapse because of crouching and bending the whole time. So I took a break, emptied my water bottle, and packed the things up for the return trek to the car, which in this case is happily only about 500 meters. I stopped in for roast beef with onions and french fries on the way home, so that pepped me up a bit I've also just discovered that Kytta ointment is good for aching wrists.

    Another Multiblock

    We're still allowed to move about freely here in good old Baden-Wuerttemberg, so I figured as long as this is still the case, I'll mosey along to my spot in the Callovian in the Wutach Valley. A friend of mine has been working there recently, so I was hoping for some more fresh exposure and sure enough, he'd opened up some new possibilities for me. Spent the good part of the day prying and hammering and came up with a few nice things. Here's the first and probably the best which I just finished prepping this evening. A multiblock measuring 12x12x6cm with 4 x Choffatia sp. and a bit of belemnite. The 4th small ammonite can't be seen in the photos since it's tucked away tightly on the back.
  7. One of my customers is keeping me quite busy lately. Last week he brought me among other things a relatively large, 22cm. diameter Callovian Choffatia ammonite from the Wutach Valley with another few smaller ones plus a belemnite attached. He asked me to send him play-by-play photos, which I did, so I figured I might just as well show them to you guys as well. Here are pics of both sides in the raw. As you can probably tell, it was extracted in 3 pieces which he glued back together. You can barely see the belemnite on the right in the middle of the first photo and the smaller ammos are at the bottom right in the second one. First step was to remove as much matrix as possible with the stylus, but soon after I started, the bit with the ammonites and the end of the living chamber popped off at a hairline crack, so I set them aside for reglueing at a later point. Here's how both sides looked after a few hours with the stylus and also after glueing the above mentioned pieces back on.
