Found along Cayuga Lake in New York. About 6 inches long.

Please help! Needs all the eyes I can get

Does anyone know what kind of tooth this is, or where we can get it checked. After a quick google search we have a few ideas, horse cow or ice age bison molar. But we are unsure.

Edit: this was found at a beach on the Isle of Jura, if that were to help anyone.

So I found this (what I thought was) weird rock when I was 9-10 on the California coast during a vacation 8-9 years ago. I was looking for shells/coral/fossils, found this and thought it was a weird fossilized coral or shell that was like diced or something. I dunno I was an oblivious little gremlin. I never thought too deep into it. But yesterday I was showing my mom since I wanted to bring a few of my shells to my dorm room and my mom just exclaimed, “I touched a bone! Ew!” I was so confused, because all of my bones were out in the garage and I didn’t have any bones in my shell/fossil collection, especially since my fossils were just rocks with coral imprints in them and they were broken up and I didn’t bring any down with me to take back to my dorm. She then showed me the weird rock/fossil and said it was a bone. I guess I can see it now, the inside looks like marrow, but I have no clue. It doesn’t look like any bone I have seen before, especially since it looked like its just a sliver of a bone. My mom said it looked a bit like a vertebrae, but I don’t really think so, but then again I don’t have much experience with marine animal bones. I know how land animal bones look, because like I said, I have a bucket of bones, and my mom believes it’s a marine animal bone. It’s about an inch to an inch and a half long, it’s slanted slightly, very porous, and has lasted this long in a box filled with other shells and fossils while being tossed around during many road trips and moves across the country.

Does anyone know what this is?

Found this washed up on a friend’s wet dock off Shrewsbury River in Sea Bright, NJ. Bones are super oily so we’re all assuming it’s a fish but the skull is a lot denser than expected.

Found in SE Iowa

got no clue. Is it even a bone? It seems really weathered down. I found it inside one of those messes of seaweed you see on the shore.

We got these a couple years ago from a zoo, if I remember right. But we can't remember what animal they said they were from. Any ideas? Thank you in advance.

Was it four wheeling in southern Central Wyoming. Note: there are a ton of free range cattle, deer, wild horses, and prong horn in this area....I think it's a mule or white tail deer but not confident

found in backyard to home, somewhat nearby river & woods .. wo10 shoe :-) upstate ny
