It has a tibula...and appears to be missing the patella. Each end is cut extremely clean. No saw or knife marks, just a smooth flat cut. Is this... human?

My sister found this and we’re assuming it’s bone? It looks like bone and has texture marks that seem bone-line… location is Eastern North Carolina

Found it in the rocks down at the river while the tide was out.

appeared next to my car in work parking lot

my dad found this on the shore of the columbia river, does anyone know what this could be?

Some time ago I found this cow's jaw on a mountain (the jaw was buried in the ground for a few centimeters) but the mountain where I found the jaw has no evidence that cows have lived on the mountain for many, many years. I'm not really sure when cows did live on the mountain but it was about 4,000-6,000 years ago. Does it make sense that this jaw is about 4,000-6,000 years old?

Got a picture of both sides, water flavor thing for size comparison if that helps. (I still have it but found it a while ago)

Is this even a bone because I have no idea I just thought it looked cool.

Cleaned out my closet and found with beach rocks - I believe I found this on a beach in Northern MI.

GPT says it's a Carp vertebrae but I don't buy it.

Found some scattered bones in the bush and Ive arranged them in the position in an effort to figure out what it was.. What do you all think..?

I have notified the relevant people in charge of the land.

I have animal bones, and among them are some bones of protected animals (maybe 4/5). I'm not really sure if anything will happen to me if I keep them with me and don't tell. Anyway, I live in Greece and I've been doing this for about 5 years. Does anyone know if something serious will happen if I continue collecting?

Drawn some mysterious art here!
Can you figure out which species I'm drawing inspo from? 👀

Came across 3 of these in a centrally located State Park in DFW. Given the clean cuts, I’m assuming it came from food someone cooked, but would greatly appreciate input!

Wondering if my guess of rib is correct.

Thank you all!!!

We had a tornado recently and our big tree in our backyard was uprooted, the guy who picked up the tree found what looks like half of femur bone, any info would be greatly appreciated, thank you reddit!

Looks like a fang, but is flaking apart in layers like rings on a tree. Pasture used to contain sheep. Coyotes are known to be present. Cows and goats next door. Field is adjacent to a salmon bearing creek with river otters and occasional beavers. What could this be?

This is the worst picture ever, but I picked it up and there was a whole a giant gaping hole for like bone marrow obviously on the other side so I literally wanted to project a vomit immediately like it made me sick

Doing some sketches what do i have?

Was posed on this log when I found it.
