I recently recieved a very interesting block with two ammonites of the same species to prepare on commission which I would like to show you here. They lay about 10 cm. apart one over the other, so either they were imbedded at different times or else they reached their final positions through turbulence. Staufenia staufensis is the species, one having a diameter of 18cm. and the other one of 16. They come from the Middle Jurassic bradfordensis zone of the Late Aalenian.

I'll show you the progression of the preparation using 4 blocks of 4 photos each showing different perspectives of the block. The first thing I did was to rid the block of as much excess matrix as possible with hammer and chisel, but I didn't think to take photos of the original, so the first photos to be seen are the ones taken after that.

Below is the state after a few hours of work with the styluses. It's starting to get into shape now.

Then I spent the next few hours abrading and fine-tuning the shape with the styluses, rocking back and forth between the two as necessary.

Last but not least there was still a little fine-fine tuning, abrading and smoothing to do before I applied the Rember. Here's the end result.

Well done! The orientation makes it appear like some sort of strange gear device from the Jurassic. :D I would be a little nervous applying a hammer and chisel, but you're a pro and this turned out lovely. :dinothumb::ammonite01:

I think the dinos were about to experiment with the wheel, but I guess they had some second thoughts about it in the end, since they didn't want to have to deal with the likes of Greta Thunberg. If you'd have seen the block beforehand you might not have been so nervous. The hammer and chisel work saved me about 4 hours worth of stylus work.

Thanks for showing us the progress. It will look sweet on a nice revolving platform for display.
