Ludwigia Posted January 4, 2019 Author Share Posted January 4, 2019 I decided to tackle a couple of the smaller ones this morning. One good, one dud. You never know how they're going to turn out in this horizon until you get down to prepping them. Well, 50/50 ain't bad. You'll have to be patient now before I can show any more results, since I really do have to get back to my commission work. First the dud, then then good one: Now a good Macrocephalites sp. with a diameter of 8.5cm. 4 Greetings from the Lake of Constance.

Kane Posted January 4, 2019 Share Posted January 4, 2019 That did turn out lovely (the non-dud one). It does not look like very friendly and cooperative matrix. But even the "dud" isn't all that bad. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted January 4, 2019 Share Posted January 4, 2019 I agree, lovely good one, but the 'dud' would make many collectors very happy. Lovely prepping. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

ober Posted January 4, 2019 Share Posted January 4, 2019 remarkable work. I can see the scratch marks on the second in your early innings, but what is the tool you use to get to the final pictures? Link to comment Share on other sites More sharing options...

But even the "dud" isn't all that bad. Actualy, the matrix is cooperative on the whole. It's the proportionally large amount of iron residue within it which tends to be overly corrosive in some cases. 7 hours ago, Tidgy's Dad said: I agree, lovely good one, but the 'dud' would make many collectors very happy.

Thanks, guys 2 hours ago, ober said: remarkable work. I can see the scratch marks on the second in your early innings, but what is the tool you use to get to the final pictures? That would be the air abrader as mentioned in one of the previous posts here. By the way, that last one is practically full sized. You can see the end of the phragmocone marked by the last of the septal suture lines. The rest is living chamber and if you follow the slightly raised, circular bit of shell on the flank up towards the top, you can also determine how large it actually was in real life. This points to either a male microconch or a juvenile specimen. 2 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Ludwigia Posted January 5, 2019 Author Share Posted January 5, 2019 I spent most of the day doing commission work, but I did manage to set aside a couple of hours to clean up a few of the smaller ammonites. This time I skipped the rest of the Macrocephalites and picked out 2 Homeoplanulites sp. and a Choffatia sp. I took a pic of one of the H.sp. in raw condition, forgot about the other one, though. The first thing I did was to free them both up from the matrix. Then I abraded them and coated them with Rember. These turned out to be what I classify as Grade B ones. The Choffatia turned out to be good enough to be placed in the collection. It belongs to the subgenus Grossouvria. Here's the progression from raw to stylus work, then to abrading and the final touch. I decided to leave it in the matrix since it presents itself nicely. 4 Greetings from the Lake of Constance.

Ludwigia Posted January 6, 2019 Author Share Posted January 6, 2019 I smuggled in another hour or so this morning. Sometimes I stick some little things in my pocket at the site if I think they might prove to be interesting. I was pretty sure that 2 of these were echinoids at any rate. The other 2 turned out to be discombobulated ammonites which landed in the disposal bin right away. But the echies turned out alright. The first is a Pygomalus ovalis and I think that the second one is a Nucleolites sp. 4 Greetings from the Lake of Constance.

Ludwigia Posted January 6, 2019 Author Share Posted January 6, 2019 Later on I also managed to make a start on another smaller Macrocephalites. Not quite finished yet. It's taking longer than I had figured at first, and you'll see why in a minute. First the situation in the raw. Then after some work with the stylus. As you can see in the last photo, I've left a larger chunk of matrix at the top. It was pretty hard and there seemed to be some shell material within it, so I decided to leave it for the abrader. A lot of the smaller Macrocephalites in this horizon are actually the inner part of much larger samples, so I was thinking that perhaps parts of the septal walls were in there, which could make for an instructive piece if it works out. By the way, you can see the iron oolites in the matrix very clearly. These layers used to be mined for iron in the past. The next photos are after a few minutes of abrading. The next bit of abrading took about an hour, since the matrix at these points is pretty hard and I also had to be careful not to damage much of the septal wall parts. My suspicion has been confirmed. This is as far as I got today. Hopefully I can find some time tomorrow to continue. 1 Greetings from the Lake of Constance.

Ludwigia Posted January 7, 2019 Author Share Posted January 7, 2019 I got it finished today. Looks interesting at any rate. There was even a gastropod shell in the phragmocone. Guess it was transported and deposited there after death and decomposition. 3 Greetings from the Lake of Constance.

The septa are incredibly complicated by this genus. I guess in order to give enough support to its bloated shape. 1 Greetings from the Lake of Constance.
