This fossil was found on one of Sweden's more well known Islands Gotland during my holiday travels. This Island Is rich In fossils from the Silurian period. What confuses me Is the pattern that looks just like a Favosite or Honeycomb coral yet the shape resembles that of a shell from a turtle? It Is oddly symmetrical, as the pattern mirrors pretty much from the center of the fossil. I can not see any underlying structures. What Is this? P.S - I have zero expertise with fossils of any kind.

While fossil hunting last year, I collected some shale from between two lenses of Silurian dolomite in Ohio. I have since cooked it down and searched for microfossils, and all I've found (aside from contaminating insect parts) are what appear to me like marbled fragments of bone and what might be . . . denticles? I'm really not sure and would appreciate any suggestions; please see the attached photos. All fossils are about at most 2 or 3 mm in width. Thanks!

Vestavia Hills, AL (Ordovician to Mississippian) I found these very odd rocks exposed by recent flooding. i wondered about a tree root mold or burrow for the first one, but figured low chance of identifying. Just in case, I did a vinegar soak to remove more of the mud. Today, I saw a tiny little spiral shell. Is it a fossil? (vs a modern snail that got trapped in this sediment). Any thoughts about the overall shape of the rock? Since it was found nearby, I’m including a pic of the other weird rock. I considered part of a horseshoe crab or trilobite molt, but I can thin

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

Hey everyone, today I found a new locality!! This locality is in the famous Shawangunk formation and it produces rare eurypterids. I have found Shawangunk material at a few localities but its interesting to compare the abundance of fauna at different localities. This new locality (like the others) primarily produces Parahughmilleria, However, 2 odd specimens were also found. One really reminds me of the invalid species Dolichopterus otisius. It is likely Nanahugmilleria clarkei. The other specimen is much more odd to me it could be Hughmilleria shawangunk but it could also be Kiaeropterus otis

Trying to identify this acritarch from upper Estill, Kentucky. It seems most palynological texts are restricted for some reason so I can't access papers. Thanks for any help.

Hello, Here is another crinoid I'm curious about ID. It's Silurian-aged from the Upper Wenlock Layer of Wren's nest, Dudley UK. The plating makes me think this is a bit of crinoid calyx poking out of matrix, measures about 1cm. I do see a plate missing, but I wonder if it's possible there's more crown buried in the rock that's worth prepping out.

A few days ago I spent the day collecting eurypterids with my good buddy Allan Lang. Firstly id like to thank Allan for his kindness towards me and his mentorship toward me, I'm very grateful towards him hes helped me a substantial amount and its always good seeing him. Anyway we probably found about a dozen good eurypterids as well as some neat associated fauna. Ill attach some photos below of some specimens we found! Top to bottom. Dolichopterus jewetti Undet cuticle, Prehaps the weathered carapace of Buffalopterus or Acutiramus. (Allan was generous enough to give this to me a

From the album: Nautiloid’s Trilobite Collection
Although the cephalon is slightly disarticulated, this is still a nice example of an iconic Rochester Shale trilobite. This bug was collected from Caleb Quarry in Middleport, NY, and was purchased from a good friend of mine.© Owen Yonkin 2022

This specimen was from my most recent collecting trip. It is from the Leighton Formation, which is Pridoli, Silurian. It was suggested by @Tidgy's Dad that it is likely a cryptosome, but I was hoping for a third opinion. The following pictures show the specimen. I have already posted some of these pictures, but have added scale (finally). The first two are of the two pieces of the specimen - I refer to the top image as the "external mold" in reference to the Nuculites bivalve next to it, and the second as the "cast". The last is a close up of the "feathery" section on the end.

I finished this prep of a trilo-cephalon a week ago. I kept forgetting to post it, but I finally remembered today. This is an Acaste zerinae cephalon. It is from Leighton Formation, pre usual. It is missing a small chip of the right eye - I unfortunately didn’t notice its absence till I returned home. It’s a shame, this guy would have been completely whole if I had found it. On the plus side, this guy’s a very nice color in the sun - a kind of bluish. The other trilo-bits - including another cephalon - all were a brownish color. Makes this one a bit more special. The

Fossil forum, I recently found an interesting fossil. I was thinking coral or bryozoan, but was unable to identify it correctly. It is from the Leighton Fm Maine (again), which is Silurian. Any help would be greatly appreciated. Here are some pictures of it:

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelg
