Is this a belemnite in a brick? I hope it is because if it is then it's the biggest one I've ever found.

I should add that it's 52mm end-to-end.

Found on Saltburn Beach UK

I found what I believe to be petrified wood but the pattern along the top in the second picture is different enough to give me pause- would love some second opinions!

I found this pretty small fragment of bone near a cluster of sand dollars and was wondering if there was any way to id?

Hello! I would love help identifying these guys... I have some ideas, but it feels like all of my Google searches only show much larger sized fossils even if they are similar in shape to these! The screw shaped ones have been especially hard to find a match for.
I noticed a couple of pentagon shapes amidst the circles... last slide is showing one of those.
Thanks for any ideas!!

I’m a conservation lab associate doing fieldwork trips on the west coast collecting sand and water from beaches. At some point I found this in Oregon or Washington. I have no clue what it is! Please help. It is 1.75 inches long and just about an inch at the widest point.

Found this over the weekend in Charleston,SC. Found in a deposit with several mako teeth.

It is 100% fossilized bone as it has the structure. It seems very likely it’s a sperm whale tooth but just want confirmation.

Found in Brighton and Hove, UK.

both sides have “S” line in the middle. looks like a sandwich.

Hello all. I found these along the Bouie River in Hattiesburg,MS. Crinoids and maybe coral but not sure what else

I was fossil hunting in old mine waste dump. The rocks are carboniferous. This one was on a slope near a bicycle path and tramway. Oddly really smooth from both sides.

Hi, I found this when sifting in the sand for tiny pebbles at a beach in Delaware, USA. It’s about 1 1.7 cm long and 1 cm wide (at the widest point). Let me know if you need any other info to make an ID. Thanks!

Hello all! Posting here because someone on r/artifacts suggested. The title says it all! My great grandfather found this while plowing their family farm in the early 1960s. Any idea what it could be? It has been a family mystery lol. Feels and looks like stone. If not some kind of deliberately made tool, thinking maybe a geological something or weathered stone? Any opinions? Obviously I’d love for it to be some prehistoric tool but nothing like it exists so i don’t have a clue. Thanks!

Some sort of large-ish vertebra found in a river bed in Upstate NY, i assumed it’s a fish of some sorts such as a sturgeon but im not too sure. It’s about the size of my palm, slightly shorter. I don’t have any other photos as of now but i may be able to get some different angles.

What is it?

Any idea what this could be?

i believe this is a prehistoric whale vertebrae. found this morning on a beach in San Clemente, CA. any help identifying is appreciated!

I assume it’s some sort of coral?
