  1. 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.

    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?

    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.

  10. 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.

    Two days in a row!

    Yesterday I reported on a trip into the Kimmeridgian, and now I'm happy to say that I spent the day today in the Callovian. I was suffering from cold turkey, since I hadn't been out for a proper hunt (not counting the short stints on the bike to the shark tooth site) for at least 3 weeks. This time it only started raining 10 minutes before I left the site, so I managed to skirt the danger of slipping down the slope on the way back up to the car. This time I had 5 hours to play around. There was a lot of work to do, so I was pretty tuckered out by the end of the day, but I stopped in for meatballs and rice on the way home, so that cured it pretty quickly. Now I just need to get under the shower. The preservation at the selected spot at the site wasn't always ideal. Lots of bits and bites amongst the complete ones, but only the prep bench will tell the story in the end. I took along my camera, so I'll let the pictures tell the story for the time being.

  15. Here are some interesting small fossils I found on a recent trip. The fossil in the first three pictures is 8mm long. The next two are of a flat fossil about 13mm long
  16. Hey all, I thought I would make a thread to show some of my shark teeth that I have collected from the Oxford Clay formation (mainly the Peterborough Member), feel free to comment if I have misidentified anything! Pre-Apologies, some of them are quite small.. Cheers, Jacob.

  21. Hello all, Currently digging through boxes I haven't looked through for several years and came across these two ammonites. I thought they were Kosmoceras grossourvrei but they seem to be too coarsely ribbed, Kosmoceras pollucinum maybe? Any help or advice with this would be greatly appreciated. Found in the Lower Oxford Clay of Kings dyke, Cambridgeshire. Callovian stage. Cheers, Jacob.
  22. Hello all, As part of my dissertation I have been sifting for micro-fossils using Braiser's (1980) white spirt method. The samples have yielded a range of micro-fossils, most of which I have been able to identify. However, this has stumped me. I believe it to be a tooth/toothplate from a fish, the enamel texture is similar to tooth textures I have seen before, though I cannot identify the species or if it is one. Any help or advice with this would be greatly appreciated! Cheers, Jacob.
  23. Dear TFF, Any ideas about more accurate bivalve ID? Thank you, Ricardo
