Parkinsonia parkinsoni ammonite from Germany

A friend of mine, Roger, from Germany was in Canada visiting some of his family recently and I was able to meet up with him and do some trading. He primarily collects from his local Mesozoic exposures in southern and central Germany. I swapped some Trilobites with him and in return he gave me some Ammonites that he'd personally collected and prepped. The specimen below is a Parkinsonia parkinsoni ammonite from the Parkinsoni-Zone, Dogger epsilon, Bajocian stage, Jurassic of Sengenthal, Germany.

Thanks to Roger I now have my second Ammonite from Sengenthal, here is my first.

Limopis cf. minima from Segenthal, Germany

This is the last of the Segenthal fossils I have to display for now. It's the Pelecypod Limopis cf. minima.

Camptonectes auritus from Segenthal, Germany

Camptonectes auritus is a scallop like shell that is found in the Jurassic aged rocks (Bajocian stage) of Segenthal, Germany. I like the faint pattern that is evident on the surface of the shell.

Palaeonucula variabilis from Segenthal, Germany

This is the right valve of a Palaeonucula variabilis pelecypod and came from a quarry near Segenthal, Germany where the rocks are middle Jurassic (Bajocian stage) in age.

Acanthothiris spinosa from Segenthal, Germany

Below is the brachiopod Acanthothiris spinosa that was found at a quarry near Segenthal, Germany. I purchased it from Matthias Weissmueller's E-bay store. It has a number of round holes in the shell where hematite oolites once were. This is not uncommon for fossils found in certain layers at Segenthal.

Pictavia bajocensis from Segenthal, Germany

Below is a Gastropod,  Pictavia bajocensis, that was found at Segenthal, Germany. I purchased it from Matthias Weissmueller's E-bay store.

The fossil above comes from Jurassic aged rocks (Bajocian stage) near Segenthal Germany.

Loboidothyris perovalis from Segenthal, Germany

One of the many brachiopods that are found in the Jurassic aged rocks (Bajocian stage) of Segenthal, Germany is Loboidothyris perovalis.

Superficially it looks similar to Cererithyris, like the one I wrote about here, but the plications (the wavy folds of the shell most easily seen in the anterior view) are less exaggerated. I purchased the above fossil from Matthias Weissmueller's E-bay store.

Opis similis pelecypod from Segenthal, Germany

Opis similis is a pelecypod found in the middle Jurassic (Bajocian stage) aged rocks at Segnethal, Germany. I purchased it fossils from Matthias Weissmueller's E-bay store.

Matthias does all his own prep work and really brings out the character of the shells that he finds. I like the overall shape of the shell and that is one of the reasons I purchased it.

Two for one fossil from Segenthal, Germany

Sometimes you get a fossil with some added interest in the form of epibonts or odd growth patterns. This Pseudogarantina ammonite has something a little different, a pelecypod that was embedded it in during deposition or compaction of the sediments.

You only notice the pelecypod once you turn the ammonite around. I believe it's a species called Astarte minima based on the book "Sengenthal - Ein Eldorado für Fossiliensammler - Die Muscheln des Bajocium von Sengenthal" by Matthias Weissmueller from whom I also purchased this specimen from.

You can see that it was pushed into the ammonite shell by the current or waves during a storm. The ammonite shell itself may have been broken during a storm event or had just been exposed on seafloor for a while and was starting to break down.

I like that you can see the teeth along the edges of the pelecypod shell

The fossils found at Segenthal, Germany are found in rocks from the middle Jurassic (Bajocian stage). I purchased my fossils from Matthias Weissmueller's E-bay store.
