Hello, would appreciate help with a fossil ID. Location found - Fergus Falls, MN. All rock pieces are from one larger piece that I broke apart. I removed some matrix with a Dremel tool to reveal more detail, but the "body" of these creatures were left untouched and are smooth in texture. The first six images of larger specimen has unique features on both sides. The smaller additional specimen along with the separate unfinished rocks seem to be the same creature, just more of them.

What is white deposit on this orthoconic cephalopod? Should I attempt to remove it?

It took some time, but thanks to Covid-19 (!! - see acknowledgements) its out now: A Systematic Study of upper Silurian (Ludfordian) Nautiloid Cephalopods from the Eggenfeld Section (Graz Palaeozoic, Styria, Austria) (pdf, external site) Here is my last visit to that site: Visiting some of the oldest fossils of Styria, Austria (Silurian orthocerids and brachiopods) - Fossil Hunting Trips - The Fossil Forum Best of all, some of my former specimens are pictured in that paper, especially some polished sections (see acknowledgements).

This is from Duck Creek formation in Tarrant county, not familiar with fossils from there so not sure what this is, looks very similar to a bacculite to me except for ridge running the length of it. Half cm long.

Oxford clay, Peterborough Member, Jurassic, Callovian, Whittlesey in Cambridgeshire I collected this a few years ago, and I'm unclear whether it's a large cephalopod hook, or part of a fish, or something else entirely. Any assistance would be greatly appreciated.

Looking for some info on this specimen from Eastern MO. Is this perhaps some sort of cephalopod impression partially replaced by calcite crystals? Thanks!

Hi folks! I’m kind of stuck on this one. I presume this is a gastropod and not a cephalopod because of its small size (diameter around 2 cm). But what order, family, genus and species? Its found at Mt Billingen in Sweden, in a layer from middle Ordovician (middle to upper Darriwilian).

Hi everyone! I was going through my Swatara Gap fossils when I came across this specimen, which I had originally thought to be coral. However, it looks similar to pictures of Spyroceras I've seen. Can anyone help? The first picture shows the texture, the second picture is a cross section, and the third picture is an imprint on the other side of the rock that looks cephalopody.

From the album: Delaware Fossils
Belemnitella americana showing internal molds. Upper Cretaceous Mt. Laurel Formation Delaware, USA It's not often one finds an internal mold of the guard where the internal texture is clearly visible. Although internal molds of other animals are common at this locality, any internal molds of belemnites are few and far between. Broken though it is, the lower specimen is one of my favorite belemnites.© c. 2022 Heather JM Siple

I found this on one of my hash plate, is it what I think it is, a very small cephalopod ?

Hi, all. I collected this specimen in the New Point Stone quarry, near Napoleon, Ind. It's Silurian, and was found in the Massie Shale. But I can't seem to find any information about it, specifically, the genus or species. The experts to whom I reached out were stumped. Any ideas, ladies and gentlemen?

I was collecting isorthoceras cephalopods at Graf Iowa (Elgin Member of the Maquoketa Formation, upper Ordovician). I found one partial specimen that in cross-section is about 8-9 times larger than any other I’ve found there. This first pic is from the field. (Don’t worry, the next photos have a scale cube in them!) The large specimen is about 8.9 cm by 5 cm. You can see cross sections of the usual-size isorthoceras in the rock (filled and infilled), and they’re closer to 1 cm across. Unfortunately, the specimen is fairly fragile. I’ve already had to glue together six pieces it fell apart into, and I haven’t been able to remove it from the matrix any further to get a better look at its sides. I’m wondering whether it’s an unusually large isorthoceras or a different animal altogether. Thoughts?

I found this partial curved cephalopod at the famous cephalopod beds (Maquoketa Fm, Upper Ordovician) at Graf, Iowa last year. It is the only non-Isorthoceras cephalopod I have found from here in my several trips. The only other cephalopod I have seen described from this site is Beloitoceras, but I don't believe that is what my specimen is. Has anyone come across anything similar? Thanks for your thoughts.

Devonian Ammonoids, Cephalopods, and More from Foreknobs Formation of New Castle, Virginia
fossil_lover_2277 posted a topic in Fossil Hunting Trips
Hiked up to some Devonian Foreknobs Formation exposures yesterday on a mountain in the Jefferson National Forest in Craig County, Virginia. Found some awesome and beautiful ammonoids, cephalopods, and more!!! Now I’ve just gotta find some trilobites and crinoids...lol Some of the better ammonoids I found in some mudstone: Some of the different types of cephalopods along with some brachiopods: And 2 unknowns, not a clue in the world what these are:

Here are three views of a 9 mm "Peritrochia sp." Girty 1909. It was found at the Lost Creek Lake spillway in Jacksboro. This proves that even a broken, partial fossil is worth taking home. In the first position you see the elaborate suture pattern characteristic of these Goniatites on the outermost whorl preserved. Notice the slight horizontal groove near the bottom edge. As it turns to reveal the next whorl below you can see the siphuncle as a vertical line and the outer edge of a septum, or chamber wall, at the bottom. Turning into the innermost whorl the septum comes into view at the top and the siphuncle is visible again. Here you also see another shallow groove crossing horizontally. These "constrictions" are found on some Pennsylvanian Goniatites. Peritrochia.mp4

I have been working with Mississippian age nautiloids in Kentucky for the past 40 years. Years ago I found two very complete specimens in the Nancy Member of the Borden Formation in a creek east of Morehead, Kentucky. The one was a small but very complete Orthoconic nautiloid of the genus Michelinoceras sp. which is commonly found in that area. The other was found very close to the other and at the time I thought it was another Michelinoceras sp. Recently I was looking at it and saw the shape was much different. Michelinoceras is very conical and the shape is very round to slightly oval with the Siphuncle in the center. The unknown specimen is also orthoconic and shows the living chamber and upper shell is just lightly oval similar to Michelinoceras sp. but the end of the shell thins on the sides to the shape of a Baculite shape. The specimen is highly replaced with calcite and the siphuncle is hard too determine. What may be the siphuncle is located at the upper part of what I think is the venter. If I am correct it would be a Bactritida type of nautiloid that were common in the Devonian. I have researched the treatise as well as many papers on Mississippian age cephalopods I can find. I am hoping someone may have ran across a similar specimen. The first and second picture is of the Michelinoceras sp. specimen. Approx. 4 inches long and typical Michelinoceras specimens. The rest of the picture are of the unknown specimen, the red circle is the area where I believe the siphuncle is located.

I found these photos in marbles coming from the North West of the Red Sea. Can any one help me in identifying them?? They sometimes look like Orthocone, but I´m not so sure! Many thanks in advance!

I found this piece by "popping" one of the "dishes" on a slab at Lang's Quarry in Ilion, NY several years ago. In this case, there is a bivalve-like fossil which was suggested to me was a cephalopod. Does anyone know the species of this fossil? I'd really like to learn more about it.
