Possible Dino raptor teeth?

Anyone have an idea of what’s going on here?

My dad makes modern arrowheads out of chert he collects in western missouri. Most of the material he finds has small fossils, but this piece had this larger bulbous fossil that was roughly 1.75 inches in diameter. He tried his best to finish the point without breaking up the fossil, hope you guys enjoy! I am still looking for an ID for this as well.

My coworker found this tooth in the Conecuh River in Alabama, USA. It’s roughly an inch wide. Any ideas?

My wife wants to break this open with a hammer, before she does. Does it look like something embedded in there? About the size of a jr football

Any idea of what it might be ?

I know nothing about fossils and would love an idea of what these could have been! I hiked to a remote alpine lake in the Rocky Mountains of BC along the Great Divide. A log book had directions to a “fossil pit” and sure enough, this rock slide was full of these. Thanks for any insight!

Found in general area of the gunflint formation in Ontario famous for it's stromatolites. But I'm not sure if it actually is a stromatolite of just some really interesting chert. Second photo Is what I think is the stromatolite, first is showing a small piece of the rock that I chipped off to check the colour. Happy to see some pyrite in it :)

Inherited from nebraska kansas area, so assuming its a marine reptile but would like to know what they actually were. 4 of 8 similar sized vertebrae 🙏🙏 thank you in advance, you beautiful people

Would love to know what this could be! Thanks in advance.

I got this at an estate sale NY State. I have no idea where it came from. It's polished.

Found tumbling in the surf, it is heavy for it’s size, lines have a dull but quartz like appearance, overall texture reminds me of asphalt. Bivalve fossil? just a cool rock?

Hello! Found this on the beach earlier. Forgive my ignorance, I know nothing about fossils. Is it anything interesting? Is it even a fossil? Thank you!

Found on Lea Island in NC

I do not know anything about fossils but I found this super cool and I wonder which fossil is this. I will post a closeup in the comments!

I was exploring an exposure of the Valudavur Formation in Pondicherry, India, mainly with the goal of finding ammonites, since the formation is known for marine shale–marl deposits representing a shallow to offshore marine environment.The stratigraphy suggests a marine setting, but there are also signs that parts of the deposit are reworked, which turned out to be important.

Instead of ammonites, I ended up finding two tooth specimens:

(larger tooth): This is the main piece of interest. It’s relatively robust, slightly recurved, and appears somewhat laterally compressed rather than conical. On closer inspection under magnification, the specimen appears to show microserrations on both edges. Overall, it doesn’t look like a typical fish tooth.

The larger tooth is where things get interesting.

A paleontologist I consulted suggested that it could be:

“An indeterminate theropod tooth, possibly abelisaurid and the smaller one is 100% sharl he said"

hello lovely people! long time lurker, first time poster. i found this when i was a kid in about 2005 in ashridge, southeast england, and have held onto it ever since because i thought it was cool. any chance it’s a fossil? it was in a forest, and there’s a lot of chalk and flint around the area if that helps. if anyone has any ideas whatsoever, i’d love to know! thank you so much :)

I found this imprint at dinosaur ridge in Colorado. It was pretty off the beaten path because i didn’t even realize I went off one of the trails lol. Anyway tell me if I’m crazy but it looks to me like possibly a dromeosaur or ornithopod tracks. If it’s a dromeosaur it would be an exceptionally rare find especially for this area. and I would be ecstatic. It was near beach ripples similar to the other tracks found there but I went quite a bit further up the mountain. Anyway what do we all think. Track or no track. I’m remaining skeptical so I’m excited to hear what we think

Found these today at a beach in Greece does anyone know what they are ?

Have no idea what this is! Thought maybe it was part of a conch shell, but the texture and pores look wrong to me. Feels more like a dried sand dollar, but the shape and plating on the top make me think it’s not. Feels a bit heavier than a sand dollar too. Any ideas on what it is are welcome!
