I was wondering if I found an external mould of the Devonian gastropod Platyceras. The fossil curves in the rock which was hard to capture with the lighting. The rock was too big to carry back and I didn’t have a ruler with me so I apologize for lack of scale. Thanks!

Interesting fossils found in bag of river rocks from Petsmart
Brad Taylor posted a topic in Fossil ID
So I was caring for my snapping turtle when I found these 4 rocks in his tank. 3 of them are undeniably fossils. I was wondering if anyone knew what type of fossils they are. One looks to be some sort of clam, one looks to be the tail of something, and the other almost looks like a turtle shell. The rock that looks like a turtle shell has a smooth top, what looks like car tracks under it, and a hole in the middle where a turtles head could go. As you can see by the photos, they are very small, and there's likely much more in my turtles tank. There is a 4th rock that I didn't take photos of that has a few black hair-like things stuck to it. I would love to know what types of fossils these are.

Found these weird spirals in this chunk of agatized rock. Devonian from Bradford beach in Milwaukee. Thanks!

Afternoon, Was looking through some drill cuttings from the Oldsmar formation ~2600 feet bls and am wondering if the majority of these are similar to Ranikothalia from looking through some papers from Yucatan. These are all Eocene in age; any help would be appreciated and I will add more images as we bring in more cuttings. The more spherical images are from higher up around ~2100 in the glauconite layer. Sorry for low quality it's a cheap microscope. Thanks, Ekker

Phosphatic concretion, Muncie Creek Shale, Kasimovian/Missourian Stage, Pennsylvanian Kansas City metro, KS/MO, USA I'm pretty sure this is a mollusk. The fine striations remind me of those on some Poterioceras: Any ideas?

Hi All, Sorry, not looking for an I.D but I couldn’t find another discussion to add it to… We took a trip to California recently and one of my beach finds was this funny “Picasso” fossil which I thought was good for a giggle. Also visited Shark Tooth hill, but that’s another thread for sure.

Yesterday I stumbled across Poricy Park Fossil Beds, which led me here after digging, but I was fortunate to find some of my own first fossils, and was even gifted four large ones from a passerby who stopped to make sure we got something good out of the experience. All of the said fossils are aquatic molluscs (or maybe sponges? But they definitely look like bivalves). Here are the four gifts: Here is a shell fused with a rock, although quite well: Some sort of clam piece? Another of the same/similar build And something very similar to the four fossils we were gifted, albeit much smaller, but we found ourselves! Also, is using 3rd party photo uploaders, such as flickr, allowed? I feel that may be easier for me to upload everything. Wasn't sure so didn't want to risk it :). Thank you for any help you give me!! It is greatly appreciated by the newbie :3

I have no clue what this is, though it looks cool and somewhat demonic. Appreciate the help.

ID help. Crustacean, mollusk, or something else? Upper carboniferous.
Gramps posted a topic in Fossil ID
I have found several of these in an outcropping of shale and limestone in the Iola Formation in Northeastern Oklahoma (middle Pennsylvanian). The longest dimension is about 15 mm (≈ 5/8 inch). Some of the other specimens are slightly larger, but all have the same pattern of bumps. (I photographed this one because it shows the least wear.) I’m wondering it might be the carapace of a phyllocarid or some other crustacean. Alternatively, it might be a bivalve or other mollusk. Any help with ID would be appreciated. Focus and exposure were difficult, so there are several images. Best wishes.

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!

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.

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 think of more arguments against than for these. Thanks for looking.

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.... formation I found. Please, tell me all that you know.
Ikikit posted a topic in Rocks & Minerals
Found this out hiking and was hoping someone could give me a more knowledgeable analysis of it, based on what can be seen from the photos. Good luck to everyone out hunting fossils and whatnot and thanks in advance for any replies.

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!

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?
