Ludwigia Posted July 21, 2013 Author Share Posted July 21, 2013 (edited) Yet another facies block from the Upper Aalenian, this time with 7 samples of 2 different species. I've posted a report on the preparation: http://www.thefossilforum.com/index.php?/topic/39172-another-aalenian-facies-block/?p=430159 A. opalinoides: The upper 3 larger and the 2 smaller ones. Ludwigia haugia: The 2 lower ones. The size of the block is 27x24x7cm. Details: Edited December 25, 2014 by Ludwigia Greetings from the Lake of Constance.

Ludwigia Posted July 23, 2013 Author Share Posted July 23, 2013 Roger.... Very nice specimen & work....These are pretty big rocks laying around....Are there any really huge ones you could have a go at?.... Steve, they don't lay around. They're stuck in the cliff and I have to pry them out. Sometimes I manage to remove a huge block, but you mostly have to reduce them in size in order to determine if they're worth the long transport, which is partly uphill. I suppose you could theoretically recover some, but you'd need a block and tackle and lots of hands to get them back to the car. Besides, my display space is getting somewhat limited Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Ludwigia Posted July 23, 2013 Author Share Posted July 23, 2013 (edited) Ancolioceras opalinoides appears in my experience to be the most common ammonite in these particular banks. I've just finished preparing a few more of them. This didn't take nearly as long as on the facies blocks since they split relatively cleanly out of the matrix. This one measures 8.5cm. It is associated with the bivalves Myophorella cf. formosa on the right and Entolium demissum on the left. Three more singles all measuring roughly 6cm.

Ludwigia Posted July 27, 2013 Author Share Posted July 27, 2013 (edited) One last one before I leave for Canada tomorrow. At some point I have to start packing my suitcase. This one is an all-round little block with 5 samples of A. opalinoides in various sizes. Another interesting one from the aspect of tectonics as one can see from the rehealed crack running through the 2 upper ammonites.The matrix was extremely hard and the largest one at the top was actually much bigger, but I didn't manage to save it all and have had to do a bit of reparation.

Ludwigia Posted July 27, 2013 Author Share Posted July 27, 2013 man, roger, you are quite the one man ammonite factory! I must say, Dan, I'm starting to get rather overwhelmed myself! I've haven't found such a fruitful site in years. At least I'm forced to take a break from ammonites now and shall be soon rummaging around in Ontario's paleozoic.

Ludwigia Posted September 24, 2013 Author Share Posted September 24, 2013 (edited) Well, I've been back to the Wutach a couple of times since my return to Canada and have managed to prepare some new finds. Same old species, but some nice samples. The first is a Ludwigia haugi. All the others are A. opalinoides. Front & back. Edited December 25, 2014 by Ludwigia Greetings from the Lake of Constance.

Ludwigia Posted September 25, 2013 Author Share Posted September 25, 2013 nice work roger, as always! Thanks! I've just finished a couple more, one of which I've had to "fill in the gaps" with some stone meal, but I'm happy nevertheless with both of them. They both appear to belong to the same species, which I believe to be Staufenia sehndensis. It's interesting to compare them both, since the first one(14cm.) is much larger than the second(9cm.). They both seem to be just about full size and if you look closely, you can see that the phragmocone of the first one is much larger than that of the second. Here are front and back views of both.

Terry Dactyll Posted September 25, 2013 Share Posted September 25, 2013 Roger.... Great specimens as always.... Your best drawer specimen must change constantly with new arrivals.... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...
Ludwigia Posted September 25, 2013 Author Share Posted September 25, 2013 In common US Southern-speak, "y'all" is used only in a plural sense, referring to more than one person. As in, when addressing several folks--"Y'all come on over for some sweet tea after the football game." As you've likely already pretty much figured out..."Bigguns" connotes just what it sounds like--big, huge, giant, remarkably sizable. Of course, I'm reading between the lines here, but I'm reckoning that danwoehr means to say that since everything's bigger in Texas, he could certainly show you where to find quite sizable ammonite specimens. Grin. Thanks for the translations. You're right, I did actually know what "bigguns" are. I've seen enough of his wagon wheels to turn green with envy. As you probably may conjecture, that exchange was all in good fun. I used the plural y'all in referring to Dan and his lovely wife, the former Ms Brett. It honestly would be nice to meet up with them again. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Ludwigia Posted December 26, 2013 Author Share Posted December 26, 2013 (edited) Well, it's been a while...I was pretty busy with the move the last couple of months, but now the apartment is more or less liveable and I'm happy to finally have my workshop set up again, completely renewed and out of the dusty, cobwebbed and cold basement in the old house into a warm and comfortable winter garden in the new one. Here's how it looks now. I'm very happy with the set-up now that I've made a few improvements. I've been trying it out for a week or so, working on one of my finds from before the winter set in of which I'd like to show the progression of the preparation here and also the satisfying end-result. It was a large block split into 2 larger pieces which contained what appeared to be the largest Staufenia staufensis which I have found to date, and one smaller piece which might have had some smaller ammonites which could have made for an interesting multiblock if they were at all well-preserved. Top view with one side of 1/2 prepared. Side view showing phragmocone Bottom view As it turned out, the smaller piece just produced a couple of little ammonites that weren't worth keeping attached, so I set that aside.

Ludwigia Posted December 26, 2013 Author Share Posted December 26, 2013 I decided to finish off the half on the right next. I figured it was much too early to glue them together, though, since I needed to do a lot of exploring in order to find the exact position of the shell. It turned out to be a good decision, since the shell was somewhat deformed due to pressure, which made for a few surprises. The concretion at the right was really tough to remove. I think I've mentioned in the past how hard this matrix can be at times. Despite my careful approach with the air scribe I still couldn't avoid making some scratches on the shell, which I more or less managed to camouflage later with the air abrader and the final coat of Rember. It was also necessary to use the air abrader on the edges in order to avoid shell loss from the pen, which took ages at 116psi. Here's how it looked after the rough finishing..... ...and here they are after some abrading placed side by side....one down, one to go...I think I'd been at it for 10 hours at this point. Another few hours of chopping and spraying on the backside cleaned up the one half roughly. Here they are placed together again. Greetings from the Lake of Constance.

Ludwigia Posted December 26, 2013 Author Share Posted December 26, 2013 (edited) Here's the last half on the way to finishing. And here's the backside after rough finishing. It was at this point that I finally glued the 2 halves together. The purple asterix at the bottom marks the end of the phragmocone and the beginning of the living chamber, which was probably wound around to 4 o'clock originally. That was a biggun, as Dan likes to say. All that was left to do now was the fine work, mostly with the abrader, but also with a bit of chiseling on the really tough remains. Finally filling in the cracks and crevices with stonemeal and a coat of Rember to conclude. That alone took about 4 hours. Here it is.
