3.5cm. This specimen with its shell mostly intact shows the innermost whorls of this subspecies. The venter at this stage is flat, but it rounds off at a later stage and gets covered up as it grows. From the koenigi zone, lower Callovian. Found in the Wutach area.-

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.

Hi all, Last part of my finds of the year. In autumn, between lockdown 1 & and lockdown 2, we managed another 3 days hunts. First day was spent in our usual trilobites spot, which happened to be on the way to our main destination this time. You have already seen in my first part some of the trilos we did find on that day, which was a rather good one for me. Day two was spent in Nanteuil quarry not far from Niort. the quarry got mostly bajocian and aalenian. the aalenian is on the "ground of the quarry" and was mostly drown at that time of year. So Bajocian that was. An explosion had occured recently so we had quite some material to process. Most of the ammos there have no heart, which is quite frustrating, but from time to time, you can fine a pretty one. 2 finds on that day : Normannites sp ammonite A huge not yet determined nautiloid (not the usual cenoceras we find there) We kept going till 18h30 then it was time for a shower at the hotel and a meal at the restaurant. -

I've been working at this site on and off for several years and decided it was time for another visit. A colleague of mine joined me in my efforts a year or so ago and he's been working diligently at it ever since. He recently informed me that he had opened up an exposure one zone higher up (koenigi) above the one we have generally been working at (herveyi) and had freed up what seems to be a promising row of blocks, judging by the finds he was making. So I figured it was time to have a look. Sure enough, after a couple of hours of hammering and prying, I managed to extricate a good sized Macrocephalites and several Choffatias which were amongst the ever present shell breccia in these turbidites. There was what appeared to be a nice surprise after I removed the next block. I was nevertheless a little wary, since the preservation at this level isn't always optimal, but the only way to find out is to get down to it, right? After about a quarter of an hour, I could see that the outer whorls were pretty rotten and in no condition to be saved. But I figured I might as well remove the overburden and at least try to save the inner whorls. This took about another hour. As you can already see, there are cracks running every whichway through it. No good sign. And once I had extracted it, it became obvious that it wasn't worth saving, particularly since the innermost whorls were nonexistent. Normally if they were there I would have tried to glue it all back together, but like I said, it just wasn't worth it to me. Well, that's the luck of the draw, isn't it? You'll never know until you've tried. I decided then and there that I'd leave that row of blocks for another day and began to hack down through the soft marl below to the row of blocks in the herveyi zone where I managed to dig out a few nice little ones. I found a few more later on, but didn't think to photograph them, since darkness was beginning to set in and I was starting to think about the can of Red Bull waiting for me in the car. Despite the disappointing giant ammo, I must say that this was one of the more successful digs I've done recently. I'll start posting more here once prep is under way.
