Ludwigia Posted May 8, 2015 Author Share Posted May 8, 2015 (edited) I suddenly had a couple of hours free time on my hands this afternoon since our coworker conference was cancelled at short hand, so I headed off to the valley for lack of anything better to do and ended up making a few nice finds. I got these ones prepped already this evening. I love this one! A complete Crussoliceras divisum crusoliense with a circumference of 16cm. and a little Glochiceras sp. hanging on. This little tube worm was on the back of it. Glomulera gordialis? 4mm. I think this one is my first Pseudowaagenia cf. micropla. 4cm...... I was wrong. For simplicity's sake it's now Aspidoceras sp.

ynot Posted May 8, 2015 Share Posted May 8, 2015 Very nice Crussoliceras divisum. I especially like the tube worm on the back side. The other one is very nice also.

Ludwigia Posted May 8, 2015 Author Share Posted May 8, 2015 Glad you like them, Tony. The tube worm was a nice extra. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Ludwigia Posted May 8, 2015 Author Share Posted May 8, 2015 Turned out that I was wrong about the Pdeudowaagenia. I've changed the id to a simple Aspidoceras sp. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Everhardus Posted May 12, 2015 Share Posted May 12, 2015 Just a question. Since you are so quick prepping them i wonder if the material differs very much than the ammonites that are found in the Graefenberg Quarry. Seems more or less the same material / age. it takes me a lot of time to prep these properly. So maybe these are more wheatered ? Could also be my pen which is air driven but a simple beginners pen..... Link to comment Share on other sites More sharing options...
PFOOLEY Posted May 12, 2015 Share Posted May 12, 2015 ...I love this one!... Me too. Fantastic specimen. "I am glad I shall never be young without wild country to be young in.

Ludwigia Posted May 12, 2015 Author Share Posted May 12, 2015 It's not very often that you find such a complete beauty. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Ludwigia Posted June 1, 2015 Author Share Posted June 1, 2015 (edited) Another recent find. This is only part of the phragmocone. In real life this creature was probably half a meter in circumference. Pseudhimalayites uhlandi. 15cm. Edited September 27, 2015 by Ludwigia Greetings from the Lake of Constance.

Manticocerasman Posted June 1, 2015 Share Posted June 1, 2015 Roger, You still amaze me with all your discoveries in the ditch and the variety of ammonites you find there. How many different species did you collect in the ditch? Kevin growing old is mandatory but growing up is optional. Link to comment Share on other sites More sharing options...

Ludwigia Posted June 1, 2015 Author Share Posted June 1, 2015 an aptychus?? You got it. Part of the jaw aparatus (or operculum) of an Aspidoceras ammonite: Laevaptychus obliquus. 1 Greetings from the Lake of Constance.

Could also be my pen which is air driven but a simple beginners pen..... Sorry, I'd overseen your question until now. The material is basically the same as in Gräfenberg, so I guess my tools are better than yours Greetings from the Lake of Constance.

Ludwigia Posted June 24, 2015 Author Share Posted June 24, 2015 I was back there again yesterday and have just finished prepping what I first had thought to be a nicely preserved bivalve shell. It turned out to be a very large Laevaptychus obliquus, the largest one I've ever found actually! Post 41 here explains what it is. It's 10cm. at the widest point and when it was together with its partner at the front of the mouth of the ammonite it made for a coil width there of 12cm. Pretty big fella! There are also a couple of spongy passengers on the back of the specimen. Greetings from the Lake of Constance.

Ludwigia Posted June 28, 2015 Author Share Posted June 28, 2015 Hey Roger...Very cool partial garage door! Excellent! Regards, Chris I also posted it in Steinkern. A lot of our members find Aptychi in the local upper Jurassic sediment, but so far everyone is bug-eyed about the size of this thing. I still can't quite believe it myself. I've done a bit of research and have seen that even larger ones have been found in the cretaceous where ammonites can reach really huge proportions, but they are pretty rare.

Yep Roger, its a very impressive find...maybe the mosasaur that ate the ammonite it came from coughed up the other half and its still out there for you to find. Keep after the ditch..it continues to amaze. Regards, Chris Link to comment Share on other sites More sharing options...

Regards, Chris Now that would be an even greater sensation finding an upper cretaceous Mosasaurier in an upper Jurassic sponge reef complex But maybe there's at least an Ichthyosaurier or a Plesiosaurier lurking in there somewhere...
