Hello, I found this on a beach along Croatian coast and was unlike any of the surrounding rocks/geology. It's symmetrical and submarine-shaped. I'm wondering if it's a fossil v. a natural formation. Any information is greatly appreciated!

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

Hi, I happen to have bought this fossil this morning but can’t seem to identify it, from the way it looks, it seems to be a mollusk but has ridges near the base where it connects to the matrix.

My collection is enriched with new pieces from the dear, old Europe. This is a Gryphaea dilatata, the so-called "devil's toenail", from Villers-sur-Mer in Normandy, France:

Interesting shell found at Douglas Point, Maryland which should be Paleocene Aquia Formation. Didn't see an obvious match anywhere online, any ideas?

Our 3rd grader found this on a beach in Coos County, OR. Her first impression is that this is a snail fossil. We’re wondering 1) what is this and 2) if this is an internal mold? There’s also an impression on one side of the matrix that looks like a separate cast. But we’re really not sure… we are having a difficult time visualizing what’s going on here. When you look closely at the spiral it does appear to have shell in there. We’ve googled a ton and compared pictures of different spiral fossils, but still aren’t sure. Thanks for any info!

Preservation of colour in fossil shells
pachy-pleuro-whatnot-odon posted a topic in Questions & Answers
Hi all, Some time ago I found this shell in (what I believe to be) the French Upper Muschelkalk (Triassic). Now I'm not into shells myself, but to judge from the remains of operculum on the underside of it, the specimen concerns an oyster. Most strikingly, however, the shell has a pattern of darker-coloured lines that do not correspond to any three-dimensional/elevational differences on the shell surface - which is, in fact, entirely flat. I haven't seen this on a fossil shell before. Now when doing a Google search for my response on whether it would be possible for cru -
Hi, this rock was found in a construction site in Bexar county, Texas. I think there are mostly mollusk shells, but I’m also really curious about the little tube things, which I’m guessing might be crinoids? Thank you for your help!

Hello again. I am currently in Al Ain (an Emirate of the United Arab Emirates), my absolute favourite place to be! I have found many fossils here, but I was quite excited when I picked this one up today. I think it's a nautilus chamber. At the same location there are tousands of nummulites, many shell steinkerns, and some urchin fossils (schizaster along with some others). I would like some confirmation! (The square is 5cm by 5cm)

Would you leave this as is or remove the casts?
OregonFossil posted a topic in General Fossil Discussion
I was lucky the last time out and found a 36" piece of a near shore sea floor. Most of it looks like this, a mixture of shells, shell fragments, and casts. Would you remove the good stuff or leave it as is? -
I introduced a coworker to pit 11 on Sunday. He was picking up all kinds of rocks, some of which I was pretty sure were not caeboniferous, but I didn't want to break his enthusiasm. Now, he dropped off his bucket at my class because I have a freezer, and in the rocks that i was sure were from the wrong Era was this nice shell! Can anyone identify it?

I'm almost certain this is a clam of some kind. It's solid rock and has all the features of a mollusk. There's a hole in the side where you can actually see the clam itself. There's a multitude of different species on the river bed here. I find oysters too. Huge ones. This all used to be lower gulf region millions of years ago according to maps

Polished specimen containing sediment/calcite-filled domichnia (burrows/crypts) formed by mollusks of the family Pholadidae (likely subfam. Martesiinae): these features were formed while the resin was in a marine environment and after it had sufficiently hardened, all preceding its burial and subsequent diagenesis. Provenance of specimen is Tanai Township, Myitkyina District, Myanmar. This image was captured using a HAYEAR HY-1070 microscope.© Kaegen Lau

Hi All, It's been a while since I have posted, let alone gone collecting but I just had a really good trip down to the Matoaka Beach Cabins in St. Leonard, MD. Here you can pay $5 ($10 on weekends) to access their beach which gives you about 1/3 of a mile to explore. I went down on Tuesday the 14th since I had some time off from work. It coincided with an extremely slack tide which directly led to many of my best finds. No shark teeth unfortunately, except for two pieces that were just roots with the toothy part broken off. I did however clean up on Ecphora sp. and Cetacean bo

Help needed for ID Miocene - Pliocene, or Upper Eocene, Mollusks from south central Chile
terminatordiego posted a topic in Fossil ID
Hello again to all of you guys , I´m in a huge need oh help to ID some mollusks of south central Chile. Currently these are storaged in the vault of a local university. I know taht the fossils in the images are not in the best conditions, but the outcrop itself sadly has been seriously reworked by a bulldozer machinery (they may be a little bit flattened). At least to a family or genus level ID should be nice considering how they actually are. The beds should be of the Miocene to Pliocene. But also theres a very minor chance of being from the middle to upper Eocene. Th -
My father found these fossils near Vilafranca del Penedes (Catalonia). I would be grateful if someone could identify their species (I do not know even if there is more than one) and how old could they be. Their size is up to 25 cm and on the narrow end can be seen, in some of them, a few grooves, sometimes blue in colour while the rest looks mostly pale yellow.

With the nicer weather last week, I was able to make two brief trips to kick of the year. There still ended up being a lot of snow on the ground, but it was manageable. My first trip was to one of my favorite sites, a roadcut in the Pennsylvanian LaSalle Limestone in Illinois. Lots of the usual stuff was found, but the two trip makers were a small Peripristis shark tooth and a Linoproductus mass mortality plate. Here's the tooth. I think it will clean up nicely. And here are the Linoproductus. There's around 50 individuals present, and they are all quite small com

Hello, fossil friends! I'm a first-time poster to the forum. I've had this little fellow for several years now. I found it hanging out among the gravel decorating an apartment complex in the southwestern United States; Tucson, Arizona, to be specific. I cannot explain why it was there, unless it was somehow ignored as a rock, or discarded by someone who no longer wanted it, but all the same, I was aware of the general shape of an ammonite, and brought it home with me because, well, its spiral was pretty! There are several dry rivers about the area, but I know next to
