Hi, @Dominik-Niehaus, are there fossils that are more exposed? That might help with the ID.
-
@samantha-ocon sorry, no, this is about all of it
-
@Dominik-Niehaus – hmm… it looks like it’s mostly bivalves.

Hi @Dominik-Niehaus! Commercially purchased fossils are fine if they are acquired legally. For the eMuseum, we like multiple photos of all the sides of the fossil, just so researchers who might be interested in looking at this fossil can see the entire thing.
-
@samantha-ocon would if I could, but this one’s glued into the case – there really aren’t more angles available
-
That’s fair! @I-Edwards is one of our resident cephalopod experts, so I’ll tag him in.
-
I already filled in the information from the label. Dr. Krantz runs the local geological supply store, so his ID should be reliable.
-
@i-edwards I don’t know him personally, I just read his name on the label 😉
-
Excellent! Thanks to both of you for working that out.
-
Do you know anything about the geology of Ron, France, @dominik-niehaus? I tried googling that city and it didn’t seem to have any results, so it might have been cut off of a longer city name by myFOSSIL.
-
@samantha-ocon I’m sorry, this is one fossil I know nothing about because I just bought it as a kid – I added a picture of the label just in case I misread it, though
-
It does turn out that I was mistaken, however – F. Krantz was the founder of the store, which is now run by his descendants. Guess I better take off that name
-
Hi, @Dominik-Niehaus – thank you for your patience. This is much like solving a puzzle for me; luckily, I’m conversational in German as well. It seems like there is no town called “Ron” in France, but there are definitely upper Jurassic strata in southern France. That might be a good place to start searching. As for this fossil entry, I think just…[Read more]
-
@samantha-ocon Done and done. And thank you for your help, I don’t think there’s a fossil I’ve uploaded that you haven’t at least tried to help identify 🙂
-
I’m glad I could help, @Dominik-Niehaus. It’s my job as curator!

-
I added some close-ups of the leaves, but as I said, they’re not ferns but seed ferns – plants that look “fern-ish” in the fossil record but differ both in the structure of their leaves and the fact that they have seeds instead of spores.
-
@i-edwards @dominik-niehaus Hi, everybody! Very cool fossil! It has a ferny texture to the leaves, so I’d say it’s a plant. In fact it looks similar to this one:
What do you all think?
-
@Nathan-Newell Yup, that looks very similar – and according to a quick Google search, Neuropteris has been found in the Ruhr Area.
-
Hi, @Nathan-Newell, @Dominik-Niehaus, and @I-Edwards! @Mackenzie-Smith might also be able to chime in!
-
@i-edwards, @samantha-ocon, @dominik-niehaus and @nathan-newell, Wow, I’m popular today. Yes, I agree with Nathan and Dominik that this is a species of Neuropteris. The midvein of the pinnule attaches to the rachis without any laminar attachment. This, however, is not a fern despite having foliage that looks like ferns. These plants produce seeds…[Read more]

Hi @Dominik-Niehaus! Could you upload a closer photo of the texture on the fossil? That would be useful in double checking the ID! Also, I’m going to tag in myFOSSIL’s resident paleobotanist, @mackenzie-smith.
-
@samantha-ocon I’ve done my best, hope it helps
-
That’s perfect, @Dominik-Niehaus! Thank you! I’m interested to see what MacKenzie says.
-
Hi @dominik-niehaus and @samantha-ocon. This is Sigillaria, a club moss tree (scale tree). Nice specimen.
-
@dominik-niehaus and @samantha-ocon. Nevermind! It looks like you already have the ID.
-
Hi @Dominik-Niehaus, can you update the stratigraphic info? Looking at macrostrat, it doesn’t seem to have a formation/unit name near Essen. Googling shows the Essen Formation as being Carboniferous. Do you have any more info? If not, I can help you look for more info.
-
@samantha-ocon given that it was collected in an active coal mine, I doubt it can be placed any more precisely than that – I can’t even ask my grandfather if he happens to know how deep they were digging at the time, he passed away years ago
-
That’s okay, @dominik-niehaus. I’ll go ahead and see what I can find; after some preliminary googling, it seems that there was a large coal mine around Essen called the Zollverein.
-
That’s correct, though I think he was in one of the shafts adjacent to it. That whole area is basically hollowed out, I’ve heard somewhere that it’s a real issue because the ground keeps settling as the old mine shafts collapse, damaging buildings and such. Zollverein was the largest, though, and has been turned into a cultural heritage site since.

Hi @dominik-niehaus, big fossil oysters are a hard group sometimes! The best match I can find in the literature from the Eocene-Oligocene of Eckelsheim is Pycnodonte (Crenostrea) callifera, which is about the right size and shape, although the shell is less vesicular than I would expect from a pycnodontine and I can’t make out any chomata. I would…[Read more]

Looks like another sand tiger. Without a root, mako teeth and sand tiger teeth can sometimes be confused with each other.

I did geotag it, it was found in the Oligocene shallow marine sediments at the Steigerberg near Eckelsheim. According to the report I wrote at the time, it’s most likely a Carcharias.

Some kind of Sand Tiger shark or ancestor but without knowing the age and with the wear, it is impossible to further identify.
-
Hi, @Dominik-Niehaus, do you have any more information about this fossil, like where it was found?

-
@dominik-niehaus, thank you for letting me know. Feel free to reach out if you have any geology questions. One of the other things that I think would improve the quality of this specimen would be to add a photo of the other side. To do this, just click the tab that says images, and you should be able to upload more photos. @Bill-Heim, would you…[Read more]

Probably Carcharias cuspidata author – (Agassiz)
-
Hi, @Dominik-Niehaus, is this a part and a counterpart of the same fossil?
@samantha-ocon yup. I’m very annoyed that I can’t place it, it’s probably one of the nicest pieces I’ve ever found
No associated location data?
None. Usually I can fall back on the field reports I had to write, but that particular trip was structured differently and I had to give a presentation on the Nördlinger Ries instead. Best I can remember, I collected it somewhere in southern Germany.
