Ludwigia Posted July 4, 2013 Author Share Posted July 4, 2013 Do you collect only these 2 periods ? Thanks for the appreciative comments. You're welcome to visit me any time if you happen to be in the area. I collect mostly from these periods because they are so to speak in my backyard and also because they have grown very dear to my heart over the years. If you take a look at my gallery however, you will notice that I am interested in collecting anything and everything if I get the chance. Greetings from the Lake of Constance.

Ludwigia Posted July 4, 2013 Author Share Posted July 4, 2013 Here's the latest result from the workshop. Ludwigia haugi. 12cm. Here's a link to the preparation work: http://www.thefossilforum.com/index.php?/topic/38733-preparation-of-an-aalenian-ammonite/?p=425463 Greetings from the Lake of Constance.

Everhardus Posted July 4, 2013 Share Posted July 4, 2013 Interesting link to the prep-process. Can you tell me some more on this stonemeal to fill the gaps ? Link to comment Share on other sites More sharing options...
Ludwigia Posted July 4, 2013 Author Share Posted July 4, 2013 Interesting link to the prep-process. Can you tell me some more on this stonemeal to fill the gaps ? You can make it yourself quite simply just by collecting and sifting the leftover preparation dust from each collecting site and saving it in labelled containers. In this way you have the right tone to match the matrix. Then you just mix the amount you need with a bit of clear varnish, or lacquer as the english call it, until it has the right consistency for application, wait for it to dry and harden after you've filled in the gaps and cleaned up the surrounding shell with a brush and water and you're done.

Everhardus Posted July 12, 2013 Share Posted July 12, 2013 Ah, ok i understand, thanks. I'm currently in France and found a nice Lytoceras yesterday. In two pieces though, probably broke it myself......It can be glued nicely but there will ge some gaps to be repaired, i'll try this method !

PFOOLEY Posted July 12, 2013 Share Posted July 12, 2013 Holy smokes, Ludwigia! Those are amazing ammonites and your preparation skills are top notch!

Ludwigia Posted July 13, 2013 Author Share Posted July 13, 2013 This site is still keeping me busy. Just finished off 2 more ammonites and a little gastropod. I believe this one to be Staufenia discoidea. 12cm. It appears to be complete with oral aperture. On one side the shell is more or less completely preserved, on the other one can observe the lobes on the calcified mold very well. Ludwigia haugi 11cm. Calcite mold. One can clearly see here where the stone was tectonically split and rehealed with calcite. This is just the phragmocone. A small snail, perhaps Riselloidea sp. 13mm. long. A rare find from the staufensis bank. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Auspex Posted July 14, 2013 Share Posted July 14, 2013 I find the little ornamented gastropod rather attractive (not to take anything away from the ammos).

Ludwigia Posted July 14, 2013 Author Share Posted July 14, 2013 I find the little ornamented gastropod rather attractive (not to take anything away from the ammos). Me too. Since gastropods are quite a rare occurrence in these layers at this site I'm happy to have found it altogether. Thanks to you Mako and Roz for your kind comments.

Terry Dactyll Posted July 14, 2013 Share Posted July 14, 2013 Roger.... The tectonically broken one that has re healed is great....Presumably any ammonite with a calcite vein running through it that runs into the rock either side has undergone this process but not the tectonic distortion?.... Great to see... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...

I seem to be discovering a number of them at this site anyway. I suppose there was a lot of movement here at some point in history. There are a good number of extinct tertiary volcanoes in the surrounding area which are linked to the sinking of the Rhein rift valley, so that might have something to do with it. By the way, the snail pictured above probably does not have the identity which I first thought. I'm still in the middle of corresponding with some gastropod experts about it.

Ludwigia Posted July 18, 2013 Author Share Posted July 18, 2013 Here's the next one. A facies block measuring 24x22x5cm. with 7 samples of A.opalinoides (one is on the back), an Entolium demissum bivalve tucked in between and a lot of broken shell substance. I love this one. Took a good 8 hours to prepare during which ever anew another ammo showed itself. I could only see 2 or 3 definite ones at the start, so it was pretty exciting discovering and uncovering the others.

Ludwigia Posted July 18, 2013 Author Share Posted July 18, 2013 Thanks Chas & Everhardus That wont be going in the drawer.... You're right there, Steve. I've parked it together with the other larger finds from this year for the time being. It's nice to walk past them every day! Greetings from the Lake of Constance.

Ludwigia Posted July 19, 2013 Author Share Posted July 19, 2013 By the way, the snail pictured above probably does not have the identity which I first thought. I'm still in the middle of corresponding with some gastropod experts about it. Joachim Gründel, one of the best experts on Jurassic gastropodes says that there are not enough visible traits for a species ID and suggests ordering it into the genus group Amphitrochus/Nododelphinula, which is what I've just done.
