Yesterday I posted a fossil which I found during a walk over the fields in the Wutach area. Earlier on in the day I had spent some time digging at one of the sites in the Callovian. Here are the best ones I found. First a Choffatia sp. (5cm.) and then a Macrocephalites jacquoti (6cm.)

Found this (likely Callovian) beauty today in Cracow, but probably it comes from Zalas, Poland. Any ideas on the ID? I'm towards algae for the moment.

I was back in the Wutach on Friday and visited a spot in the Callovian. Found a few pieces worth keeping and this is the first one which I just finished prepping. One of the more rare ammonites. A Bullatimorphites bullatus. More to follow once I'm done with the prep.

I was hoping today to continue on with my foraging expedition from last week, but when I got to my little mountain in the Wutach, there was still too much snow lying on the slopes to guarantee me not slipping and sliding over precipices, so I decided to just go to my exposure and do a bit more digging. This time I remembered to take along the camera, so I can show you a bit of the landscape and give you an impression of the digging activity. The first three pics are on the approach to the exposure. Can you guess where it is? A little hilly, eh?

I had the whole day available for a prolonged tour on Saturday, so I decided to spend it exploring the sides of the small mountain in the Wutach valley where I've been making some good finds in the Callovian for the last year or so. Since my usual dig is getting tougher to work, particularly since I'm spending more time removing overburden than I am digging fossils, I figured I'd foray on into the unknown in search of new exposures. I spent a good 4 hours clambering about the slopes at the appropriate height and managed to cover about half of the mountain in that time. I did manage to find a few exposures, but they weren't quite at the horizon I was looking for. Never mind. You can't expect to strike a bonanza every time you do some exploring. I then headed back to my usual spot and managed to dig out a few little ammonites until dusk set in. The day was by no means a loss. It just felt good having a little adventure. If the snow holds back, I may head out again next weekend and check out the other half of the hillside. I'll try to remember to take my camera along with me then in order to let you join in. Sorry I forgot it again, but here are some pics of the little ones at least.

Though I've found plenty of info to help me identify what I collected at Vaches Noires I haven't sat down to get it all straightened out, and I thought I 'd post these images of a few items found during 2-3 hours walking on the beach from Houlgate to Villers-sur-Mer. I'll see if I can't give it a go during the holidays and add a few tags, but I thank any of your suggestions :-). Of these #17 is not a fossil and include it as a comparison to #14-16 which are equally sized but much thiner and blue/black in colour. Also not sure whether #8 and #27 are fossils. Just at the beginning of the cliffs there are large numbers of rusty fragments among the large limestones and I am not sure to what extent these are remnants from shells of the military type or from boats or other harbour equipment (not that there is much of a harbour to speak of) or metal refuse. I didn't get a chance to inform myself during my short stay about this and haven't found hints online, but the Germans put a battery on top of the hill by Houlgate which was heavily shelled. The info regarding the geology of the site was swipped from the French and is only an indication of the geology of the beach where one is allowed to pick fossils, not the cliffs themselves which release fossils as they are eroded. I don't include any Griphaea dilatata which have a truly impressive heft. I wouldn't be surprised if these were used as hoes or tools and weapons back in the stone age. Cheers

20cm. A little squashed in places, but affording a few interesting views upon the septal chambers and walls. Fossilization and preservation are amazing things. Again from the Callovian in Wutach valley. -

Yesterday I returned to the new spot in the Callovian of the Wutach valley which I presented in one of my previous posts. This time the guys couldn't come, so I walked in alone, not to say without a little trepidation since I lost my way on the return journey last time. But thanks to google earth, a geological map of the area and a memory of at least a couple of landmarks, I managed to find my way in. Finding my way out was no problem, since I made sure to file away every twist and turn this time. My knapsack was however so heavy that I ended up depositing it after I'd just managed to lug it up the steep incline above the exposure and found my way back to the foresters road. I then walked out and drove back in with my car to pick it up, which actually isn't allowed, but... well, rules are made to be broken, right? At any rate, I remembered to take along my camera this time and made a few shots while at the exposure which I'll show here for starters. The first is a shot of the corner I was working on, the second a typical oops, broke it in two and gotta glue it back together in the workshop situation and the third shows my finds at halftime. Just imagine double the amount plus all your tools on your back and trying to clamber up about 20 meters of slippery slope. At least I could use my pickle to keep my balance. I'll post the prepared finds bit by bit here as I get them done. I'm particularly excited about the large Macrocephalites on the right.
