Hunt Results From The Aalenian And Bajocian In Germany

Recommended Posts

Hi

I've been busy the last while preparing my fall finds from the Wutach Valley and most of it's finished now. So I figured it was time to let you have a look. The following finds come from the Staufensis Bank of the upper Aalenian.

post-2384-0-22869300-1358263013_thumb.jpg Costileioceras sinon. 6.5cm. Could also be a Ludwigia.

Now a few from the lower Bajocian, Ovale zone.

post-2384-0-71775500-1358263245_thumb.jpg Ctenostreon sp. 5cm. long. Juvenile sample.

post-2384-0-84551700-1358263348_thumb.jpg Ctenostreon sp. 10cm. long. Somewhat deformed.

post-2384-0-22565800-1358263472_thumb.jpg ? Ooliticia sp. 2cm. A mold which is hard to ID.

Spectacular finds, Roger! :wub:

All are wonderful, but I particularly like the sutures on the Fissilobiceras sp.

Thanks for posting them.

Wonderful work as always Roger! The sutures on the Fissilobiceras sp. look like a Placenticeras (but we're talking two completely different eras, of course).

Beautiful Preparation! Finding these little gems is only half the work!

Thanks Boneman. In this layer, a third of the work is finding them, a third is getting them relatively intact out of the extremely hard matrix and the last third is preparing them. It's worth the sweat, though, as you can see.

@Jean-Pierre & Dave: Thanks for the comments.

  • 4 weeks later...

I went back there a few weeks ago during some thaw weather and found another good spot. Now that I've just about finished preparing the finds I can show you some of them. This time they're all from the murchisonae zone, upper Aalenian.

post-2384-0-74911400-1360844884_thumb.jpg
Brasilia(Apedogyria) platycora. It has a circumference of 15.5cm. and has retained most of its shell

post-2384-0-21919300-1360845045_thumb.jpg
Staufenia ?discoidea. 5.5cm. Calcite steinkern. The shell splits off often during recovery, but that's no reason to get depressed here since the molds show off the suture lines so nicely.

post-2384-0-72277800-1360845797_thumb.jpg
A double with both being Ludwigia sp. Not sure of the species yet. The block measures 11x7cm.

Edit: Both are probably L.haugi obtusiformis.

post-2384-0-97170700-1360845945_thumb.jpg
Ludwigia haugi. 6cm.

post-2384-0-04938600-1360846036_thumb.jpg
Ludwigia ?murchisonae on the left (6.5cm) and probably a Staufenia sp. (8cm.) on the right. Might also be a Brasilia though. There are a lot of transitional forms that get things mixed up.

Edit: Left: Ludwigia murchisonae falcifera. Right: Brasilia (Brasilina) baylii.

A few more:

post-2384-0-48676400-1360846305_thumb.jpg
Ancolioceras opalinoides (8cm.) at the front. Costileioceras sinon (12cm.) at the back. It's only a partial, but I kept it since I felt it makes a nice background.

post-2384-0-52700800-1360846491_thumb.jpg
A particularly pretty calcite mold of A. opalinoides. 4.5cm.

post-2384-0-93397200-1360846570_thumb.jpg
Closing off with a small bivalve measuring 17mm. It's probably a Chlamys sp. but could also be Camptonectes sp.
