Life reconstruction of the Ammonoid Koenenites
Bringing Fossils to Life posted a topic in Paleo Re-creations
Here's the reconstruction of Koenenites I promised. Koenenites was a Devonian ammonoid with a very compressed shell and sharp keel. It was designed for fast swimming and thanks to the shape of its suture, it could accelerate very quickly compared to the ammonoids around it without its cameral fluid sloshing around and shifting its center of gravity. Because of its evolute shell, it likely had a large hyponome, which goes with the shape of its shell. After looking at some pictures of Koenenites fossils from Michigan that may have preserved the Supercephalic Attachment Area, I arrived at the pro -
Hi everyone! I was just going over some of my Catskill fossils when I stumbled across this one, which appears to be two Holoptychius scales alongside lush plant material, especially on the other side (though you can see one stem to the right of the upper scale). The picture on the top is under normal light, the lower one with a bright light from the side to highlight some details. Could anyone help with ID?

I'm currently working on a simulation of extinct biomes, i'm slowly learning how to make everything as realistic as possible for realtime 3d simulation. I would like to start with plants recreated from some Silurian, lower devonian and upper devonian, and slowly working to recreating the biomes in the areas where they lived and later i'l like to add animals aswell. All my research is made with google i'm not a professional in archeology or 3d art, some of the models are very simple and unpolished for now and will be updated. The project is in the early stages

This ichnofossil consists of an accumulation of tentaculites, probably of the genus Styliolina. Dr. M. Poschmann (General Directory of Cultural Heritage Rhineland-Palatinate in Koblenz) mentioned in a personal communication that accumulations of tentaculites / styliolites from the Hunsrück Slate are known, also in the State Collection in Mainz such pieces are found. Tentaculite accumulations can occur in quite different forms, among them those which are probably to be interpreted as coprolites due to their shape and rather irregular arrangement. Cylindrical assemblages of tentaculites /

I've been cleaning up a few boxes with devonian fossils from the past few months and came around this nice little fellow. I cleaned him up and gave him a paraloid treatment to preserve the pyrite. It is a complete specimen of a Bactrites sp. from the Matagne shales ( Frasnian, late Devonian ) from Belgium, both phragmocone and body chamber are preserved. They are a little unusual, as the do not belong to the nautiloids as his first appearance might suggest but they have their own subclass and are considered to be the ancestors of the ammonids ( they have a ventral syphuncle like all

Cheiropteraster giganteus reached diameters up to 50 cm / 20”. Taxonomy from BioLib.cz. From Südcamp 2017, p. 132: “Cheiropteraster is a very large ophiuroid with no disc, but a granulated skin reaching the tips of the five arms. The mouth is extremely large and V-shaped reaching up to the fifth ambulacral pairs. The elongated ambulacrals stand out as a topographic high and form alternating half-cylinders. Orally, they are boot-shaped. The laterals are T-shaped and bear long spines along the edge.” Identified by oilshale using Südcamp 2017. References: Stürtz, B. (1890) Neuer B

I found this mysterious fossil in Richland, Michigan, and don't know what to make of it. It appears to have a fish scale and lots of bone fragments, as well as a piece of coral, in smoothed (Devonian?) sandstone. I don't know my fish very well; can anyone help?

This rare Palaeosolaster lies somewhat unfortunate on its side and is not completely preserved. A conularia is partially hidden by the arms. Taxonomy from Fossilworks.org. Synonyms: Echinasterias Stürtz 1899, Echinodiscaster Stürtz 1899, Echinodiscites Stürtz 1899, Echinodiscus Stürtz 1899, Echinostella Stürtz 1899. From Südcamp 2017, p. 124: “Palaeosolaster is similar to Palasterina, but can be distinguished easily by its 25-29 arms and large mouth. The mouth-angle plates are narrow and show high relief. The madreporite lies on the oral surface. The groove is wide. The opposite

I'm a collector from michigan and have a large amount of specimens to prep. I am starting this topic to help others and myself on the ID'S of criniods and blastoids I commonly find in michigan. I'll start this with a worn, but otherwise nice criniod my sister found last summer up in partridge point. I believe it is one of 3 species of Megistocrinus. Im waiting for my sister to send me the specimen so I can get a better look at it and add photos to this post. I'm leaning towards an M. regularis due to its shorter height than the other two examples. Just under 6cm in length and width

Found in the needmore formation of WV so early to mid Devonian. Thought these were crinoids cups for the longest time but I’ve looked and have yet to see an example that matches. I’ve found them a number of times out at this site and they always present exactly like this, down to size and placement of that center “seam”. As always, thank you for your time.

Hey everyone! I'm not the best with fossil fish; I need some help with ID. My friend told me this was a Bothriolepis plate, but I second guessed when I saw the frilling on the edge, as well as the overall shape. I know there are many fossil fish experts here...does anyone know what it is?

While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part

Found digging in the needmore formation of WV making him early to mid Devonian. Closest matches I could find were trypaulites erinus and coronura aspectans but neither look quite right. Photos of the positive and negative imprint, you can see the margins much clearer in the negative (seemingly no spines). Also ignore that small shard of pygidium to the left of the positive imprint, it is unrelated (was stacked right on top of this one and was unfortunately destroyed). As always I’m deeply grateful for your time.

High Five Trilobite!
piranha posted a topic in Partners in Paleontology - Member Contributions to Science
After a two year hiatus a fifth trilobite has recently been named in my honor. This time the Great German Trilobitologist: Ulrich Flick has bestowed Chotecops morrisoni upon yours truly. The holotype for C. morrisoni was discovered in the Devonian (lower Eifelian) Günterod Limestone of Günterod, Germany. In 1971 Professor Ivo Chlupáč established the new taxon Chotecops named for the type locality of the Chotec Limestone of the Czech Republic. Most fossil aficionados are familiar with Chotecops ferdinandi originating from the roofing tiles of the Hunsrück Slate: a classic trilobite that evokes- 32 replies

Crinoid columnals from Devonian Keyser Formation in Pennsylvania
traveltip1 posted a topic in Fossil Hunting Trips
I collected some crinoid columnals and a horn coral....weathered from the Devonian Keyser Formation limestone in Pennsylvania. As usual, preservation is not very good. -
I recently came across a fossiliferous exposure along an old rail trail near Swatara State Park, PA. Most of the fossils there were brachiopods, but I also found several interesting fossils I couldn't identify. Fossils in this area are from the Middle Devonian Period, or so I've read. These two appear to be the same species, perhaps at different stages of development: This last one (cast and mold) looks like a tooth, but I suspect it's really some kind of hyolith:

Hey everyone, been a little MIA recently. Work/life balance has gotten a little out of whack. Looking forward to sharing some of my 2021 finds soon! anyway I’m revisiting this fossil I found in Western New York roughly 2 years ago. at first when I shared the find I asked some opinions and most said cephalopod. I knew it probably wasn’t that but I didn’t really explore it further. this is from the Wanakah shale of the ludlowville formation in the Hamilton group of WNY. Middle Devonian in age. this “seems” like a spine? I don’t really know.
