Another Alpine trip with Andreas


Ludwigia

Recommended Posts

I had the good luck to spend last weekend with our Austrian member @andreas along with our friend Thomas from Thuringia. We made forays into the alpine Early Jurassic, or Lias as we call it over here, and the Triassic Tuval stage. We visited two classical sites and had a good amount of success despite limited collecting time due to approaching thunderstorms. I not only found fossils, but also 2 ticks found me. As usual, I forgot to pack my camera. Sorry about that! But at least I can show a few of the finds which I've finished preparing. First of all, some of the Jurassic finds. There's a lot of hematite in this zone which accounts for the colors.

This huge thing is called Atractites sp. It's the rostrum of a species of colioid cephalopod. Believe it or not, this is only the half of it.

Phylloceras sp.

Schlotheimia sp.

 

And here are a few finds out of the Tuval:

Arcestes sp.

Megaphyllites humilis

Sagenites (Trachysagenites) eximius

 

A1473a.jpg.a36095c74c9a33dbff89850139c91ce5.jpg

This one is either Trachysagenites cf. herbichi or Spirogmoceras sp. I tend to the latter.

A small gastropod. Probably Sisenna sp.

 

Thanks again to Andreas for showing us a wonderful time and also for the ids. The evening at his home together with Thomas and his family was really special as well.

I still have a few more things to prep, so I'll be posting some more pics later.

Glad to hear you were able to get out with friends and a fellow TFF member! Looks like you had a good time, judging by your finds.

Hi Roger,

may I help you with some pics. First field pic is showing Ludwigia roger furzensis from its dorsal side. Second pic shows the Atractites as found in field.

The Triassic Tuvalian ammonoids are from the dilleri or lower subbullatus zone.

 

Thanks too, for the nice field days we spent together,

kind regards

Andreas

Thanks for the dorsal view. I don't get to see that very often :D

Nice stuff, Roger!  I especially like this one:

It's a two-for-one special! :D

Me too. Thanks Monica.

I agree. They are nice little gems. Here are some more, from what Andreas believes to be the dilleri zone.

It is difficult, particularly for newbies to the region like myself, to determine the exact stratigraphy in these sections of the Alps, since we as a collectors are dealing with the powers of tectonics, which fold, crack, break, fault and reverse, just to confuse us all the more. The fauna varies from zone to zone which indicates which one you are dealing with, but in order to judge, you need to be able to identify the fauna. This is why I still need to rely on Andreas' knowledge, thank goodness.

A little block with 2x Paratropites sp. and various other fauna, mostly Arcestes sp., which is by far the most common ammonite of the middle Triassic.

Arcestes sp. on the left, Sandlingites sp. on the right. The latter is named after a classic site not far from this one, but a lot higher up.

...but what interested me the most on it was this Sirenites sp.

 

 

These and many others came out of a block which Andreas found and was gracious enough to give me. What a great host!

Nice complete steinkerns, give immediate impression of ancient times. The one with 40 ammonoids is a piece of art

Yes, this is a special type of fauna and preservation.

Thanks Ron. Glad you like them. Small but attractive, excepting the Atractites of course. Here's another view of the multi block for you:

Geez, I missed out on your post until now. Thanks JP. Oops, no I didn't :DOH: I think I'm slowly losing my attention span.

And here's a final one. A somewhat otherwisely formed ammonite, Paracochloceras suessi. You'd think that it's a gastropod, wouldn't you?

And you even fed some of the local wildlife... what a nice guy.. :default_clap2:

 

Oh and... beautiful finds. 

Accomplishing the impossible means only that the boss will add it to your regular duties.

Yes, I've built up quite a menagerie of these creatures over the years :P Glad you like the ammonites, anyway.

Hi Roger, I think this is no Paracochloceras.  Paracochloceras is uppermost Norian. If this piece is from the Tuvalian block that  I gave to you it is a gastropod for sure.

Oops! Just shows you how much I know about Triassic ammonites :P Thanks for the heads up. Any idea what the genus of this gastropod might be?
