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.

Found on Lea Island in NC

Not sure what it is, but thought it looked interesting when I found it. Any insights welcome!

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

Any idea of what it might be ?

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!

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

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!

I've had this thing for a really long time and I'm getting rid of some stuff. I can't find any fossils online with the soft tissue so intact and I'm wondering if it's worth anything or just interesting!

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 :)

Add-on:

After reading more, I'm pretty confident that this is most likely a stromatolite. Mostly based on the smaller dome-like appearance on the secondary dome, as well as the appearance of what looks like air pocket inclusions. Though again, I freely admit that I am completely new to identifying these and regular banded chert can have both as well 🤷🏻‍♀️ it might just be wishful thinking, but imma take my wish and live with it I guess :P

Thank you to everyone who commented and more than likely know much more than me! I'm sure you are probably right 😬

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

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

These are the teeth I've collected which I continue to struggle to identify. I appreciate your help!

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?

Found near Frankfort on Lake Michigan

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!

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!
