  3. I just couldn't resist revisiting the Callovian site again which I recently reported about here. I was figuring on removing some more overburden to get back in at the productive layer. To this purpose I brought along my heavy pickaxe this time. That saved a lot of wear and tear on the wrist, although my elbows were beginning to ache a bit later on in the day, but that was no worse than playing a couple of sets of tennis As usual, my first finds were little stuff. But then the hope-for big one appeared. It also wasn't quite complete in the end, but I'm pretty sure I'll be able to restore the missing parts once I get down to it. I had already begun to hear thunder in the distance as I began working on this and it was starting to get closer. So at this point I figured that my collecting day was soon to come to an end and started packing things away. But as luck would have it, it was just a bunch of noise and nary a drop of rain fell for the rest of the day. I managed to dig out another large ammonite which looked quite promising even after I had removed most of the overburden.
  4. 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.
  5. Possible Jurassic Wood-boring Bivalve

    This specimen was found in the Harrison Lake area of southwestern British Columbia, in beds reliably dated late middle Jurassic (Callovian). It appears to be a bivalve shell with two large protuberances emerging from it. The wood-boring bivalves Pholadacea come to mind, but, since I have no record of anything like this from the area, and no experience with these forms, I welcome your comments and suggestions.
  6. Dear TFF, I have these two Callovian ammonites for exchange. The first is on matrix and wood wax has been applied to it. I would like paleozoic material (especially devonian invertebrates) for my teaching collection, but I am open to other proposals. Thank you.

  8. I went for my first proper collecting excursion in about a month yesterday (I don't count the bike trips to the shark tooth site, since that's more of a light snack). I'd decided to take another look at one of my old sites in the Callovian in the Wutach Valley. As is sometimes the case, I forgot my camera (sorry), so there won't be any on the site photos, but I thought I could at least show you the best finds which I just finished prepping. First a Pyrgotrochus macrocephali gastropod and then a Kepplerites sp. ammonite. Both are relatively seldom, so I was happy to add them to the collection. The last two are well-preserved Choffatia sp. and Macrocephalites sp. ammonites.

  12. 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.

  14. Peek-a-Boo

    Yesterday I posted something here from my recent trip to the Callovian and now I've just finished prepping something else worth showing. It's a somewhat compressed Macrocephalites jacquoti ammonite with a diameter of 12cm. You may have noticed, particularly in the second photo, that there's a crack running through it. And this is what happens when you open it up. It had already broken into these two pieces as I was extracting it at the outcrop. Instead of glueing them back together as I usually do, however, I decided to leave it as is after I'd abraded the shell, since the view of the crystallized chambers is quite pretty. It makes a nice sort of "surprise egg", don't you think?
  15. Multiblock 13

    From the album Middle Jurassic Ammonites from Southern Germany

    Containing 4 Choffatia sp. ammonites and a piece of belemnite rostrum. 12x12x6cm. The 4th ammonite is hidden on the back side and can only be seen in profile in the last photo. herveyi zone Early Callovian From the Wutach Valley area.
  16. 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.

  20. Hi there, I'm working at the moment on cataloguing my collection. 98% or so has been self collected over the years. Lately i've cataloguing my fossils from "les Vaches noires" cliffs in normandy / France. Im not finished yet, but i think i should share. So heres my flickr galery "les Vaches Noires " : https://flic.kr/s/aHsmKUCQse i hope you will enjoy.
