Ludwigia Posted July 1, 2020 Share Posted July 1, 2020 RJB offered an unprepped Hoploscaphites from the Pierre Shale of Montana a while ago which he was gracious enough to send to me, although he normally doesn't ship overseas. Thanks again, Ron! It arrived a couple of days ago and I could hardly wait to get down to it since I've had these on my bucket list for ages. You can see the stage he had it at in the link. Here's how it looked in my cabinet after a few hours with the stylus. It turned out that the smaller one at the front was just a partial, and since there was nothing much else except broken shell material to be found in the concretion, I decided to remove the ammonite completely from the matrix. This is the stage it has reached after roughly 10 hours of work. My abrader has unfortunately broken down and I've had to send it off for repair, so this beauty shall have to wait for a while before I can finish it off. 14 Greetings from the Lake of Constance.

Unfortunately for me, I just heard from my repairman that he's in rehab right now with a new knee, so it may take a bit longer than usual. Greetings from the Lake of Constance.

FossilNerd Posted July 2, 2020 Share Posted July 2, 2020 I tend to like my fossils with some matrix left on them, but your prepped ammonites are always one of the exceptions to that rule. Great work and lovely specimen! Hopefully your repairman makes a speedy recovery so that your abrader can do the same!

Yes, at first I was thinking to at least keep a pedestal and at the same time I was trying to retain as much of the shell as possible. These ammonites have a very thickly layered "opalized" shell. But it was to no avail. Every time I got close, part of the shell split off, since the separating layer was about halfway in. Then a number of cracks appeared along the separating layer, so I decided to go for it. I suppose I could have tried to work with superglue, but I know from experience that this often doesn't always help and you end up with sporadic bits of shell between the spots where it's gone, which looks a bit funny in the end. And that method usually at least quadruples the prep time. 8 hours ago, PFOOLEY said: Very nice Roger...both on the prep and acquisition...Ive been watching for this one. I'm happy! Can't wait to set the abrader to it, but I'm needing to practice patience. 1 Greetings from the Lake of Constance.

Ludwigia Posted July 7, 2020 Author Share Posted July 7, 2020 My abrader got fixed a lot more quickly than I was expecting, so I can already show the end result 2 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
