  1. Prepping a BIG Sonninia

    I recently recieved a large Sonninia from the Wutach Valley for preparation from a customer. It was a bit of a task since the thing is so huge with a diameter of 50cm. (1ft.7in.). First of all I had to remove the excess matrix with hammer & chisel. I didn't photograph it beforehand, but here is how it looked afterwards. As you can see, the living chamber was extracted in 2 extra pieces which still needed to be attached. The phragmocone alone has a diameter of over a foot and there is still a piece of living chamber missing at the end where the brown color can be seen at the top. I didn't glue them back on at first, but concentrated rather on stylus and abrader work on the phragmocome. The next photo shows it at that stage with the 2 living chamber pieces just placed next to it. I then abraded the living chamber pieces, removed the unseemly brown layer on the phragmocone and glued it all back together with a strong adhesive which then cured for 24 hours. The next step was to fill the gaps with modelling clay (I use a product called Apoxie Sculpt) and finish off with water color paints and a beeswax finish. I couldn't get the color quite right, so I left that last step to my customer's wife who did an excellent job. Here's the end product:
  2. Sonninia sp. (Bayle 1878)

    From the album Middle Jurassic Ammonites from Southern Germany

    I prepped this ammonite with a diameter of 50cm. for a customer who allowed me to show it here. I had to glue the living chamber back on which was in 2 pieces and also fill a lot of gaps with modelling clay. His wife did a great job at balancing the colors with water paints. We think that the species is S.ovalis, but are not quite sure about that. If that's the case, then this is quite a rare find, particularly at this size. ovale zone Wedelsandstein Formation Early Bajocian From the Wutach Valley

  5. Prepping a double block

    My customer brought me another challenging assignment the other day. It's a combination of 2 different ammonite species in one block, something quite rare for the ovale zone in which it was found. Here's what I started with. There was a lot of matrix to be removed, so off we went. Here's what it looked like after a couple of hours with the scribes. Now you can roughly see the positions of the two ammonites. I never cease to be amazed at how abrading can reveal the beauty of fossils. Now the Hyperlioceras can be clearly seen on the left. There was still a bit of shell clinging to the venter at 6 o'clock, but I managed to scribe it off with minimal damage which I'll conceal later with a bit of epoxy putty. I then returned to the scribe and trimmed off most of the matrix from the Sonninia. The oyster which is sticking to it was also removed after I took the photo. The last thing I did today was to abrade the Sonninia. Sometime tomorrow I'll get down to trimming the matrix to give the block an aesthetic shape, smoothing it down and finalizing things. I promise to post the end result when done. By the way, the Hyperlioceras has a diameter of 18cm. and the Sonninia one of 11.
