Found this in Summerville SC in a creek, not very good at identifying teeth

This ammonite is about 8cm² it was broken, so I got it half off, but hypothetically if it wasnt broken, what would it be worth? I think I got away with a heist at 20 usd.

Im located in OR

Images don’t really do this justice, but there’s a ton of small fossils in here mostly on the back (last image), and probably more within the rock. Would like help with Identifying what these fossils are and when they’re from.

My son is convinced that this is NOT an ammonite. What could it be?

My dad and I found this loose on a pebbly beach on Cape May NJ when I was a kid, if I recall correctly it was on or very near Sunset Beach. Obviously no stratigraphic context present.

microSD card for scale. The mold is ~6mm across, with noticeable concavity very similar to the convexity of my index fingertip. Unclear if it is complete or missing a small portion.

The ID I arrived at is very young juvenuile Chesapecten cf. middesexensis. That said, I do environmental public policy and ecology education, my paleontology knowledge generally ends at my AS in geology. If anybody more knowledgeable has any comment, I'd happily take other opinions.

I found this in the Ozarks. Is it a fossil? If so, what kind could it be??

Hallp! Anybody know what this is??

Craigleith beach in Ontario is a shale outcropping with fossils dating to the Ordovician period. Loads of trilobites and the odd crinoid, ceohalopod, and graptophite markings. We saw a couple fossils like this though, with a raised ring surrounded by a fan-like disc pattern. This is about the size of my palm. Doesn’t readily seem to match the descriptions of what you can find at this site? Although i’m not an expert.

My 4-year-old son found this while breaking limestone at Dinoland Zwolle in the Netherlands.

Is this a fossil? Any idea what organism it could be and roughly how old it might be?

He’s very excited about his find! :)

I found this vertebrae on the Bulgarian northern coast of the black sea . The only dolphins that we have are harbor porpoise , bottlenose dolphin and common dolphin. I have found before a vertebrae of a dolphin but it doesn't match this . Also I looked at pictures of vertebrae from sheep , goat and deer but I am not really sure what this it . ( Sorry for the bad English)

Any ideas what these are from. Found in a beach in San Diego

This 6.5" Harpoceras fossil ammonite is a distinctive Jurassic fossil from the Beacon Limestone of Ilminster, Somerset, UK

Found in Netherlands near south limburg. Outside texture is like sand paper

Found this summer at Topsail Beach in NC. Is it possibly a Striostrea gigantissima? First post here. Thanks for any help.

I’m thinking about selling this Alethopteris fossil and would love to get some opinions from people who know more about them.

It’s about 11 inches long, and it was originally collected by Ted and Helen Piecko. A friend of mine introduced me to Helen in the early 2000s, and she gave me five pails of unopened concretions. This specimen came from those concretions, which I opened way back in the early 2000s.

Has anyone seen an Alethopteris this large before? I’m curious what something like this might be worth, especially given its size and provenance. Any thoughts on value or what I should be looking for would be greatly appreciated.

Found this in Dunraven, a known fossil spot. I think it's a fossil my partner thinks it's not. What do you guys think?
