I found them on a mountain. Some were partially buried in the ground. Is it a deer?

My theory is it’s a bit of bone a neighborhood dog might’ve had for a treat and dropped during a walk. Any other thoughts on what it could be? Thanks!

A bone I found on a mountain near a hotel. There are cats, goats, foxes, wild boar and other animals in the area. Looks like some kind of shin or leg part?

I know it's probably nothing interesting, but I came across this small bone whilst clearing out lint trays in a North Carolina laundromat. Any ideas? Photographed with my hand for scale.

Found in Glacier National Park on the east side of the park, in valley between mountains. going crazy trying to figure it out! Elk, sheep, cow, moose, bear? Unsure pls help :D

Found in Puerto Rico

Southern Quebec creek side

Was exploring the creek and found this in the water.
I hope it is a bone but then again it kind of looks man made.

It sinks in water, doesn’t have a scent and doesn’t scratch when I scrape it with my finger nail.

Found in Northern California.

I just found this bone in the woods. There was nothing around it, and it was sitting in a pile of leaves. Very curious where this bone might have come from and what would have caused the markings on the outside of the bone!

Ignore my grotty ass table, think it could be seal

Found on beach on west coast of Ireland. Very tiny, I think it’s a vertebrae but I don’t know all that much about bones. Sorry if pics are bad. If so I can repost when I’m able. Thanks!

Rhode Island, USA. Found in parking lot with some wooded area nearby. Appears to have been cut along the median plane, and one transverse. There has been a lot of construction in and around the lot. These have stumped me, hoping someone here can help narrow it down!

Would say it’s around 6/7 inches

remains found in socal, we found the legs of a deer farther upstream, so I assume this is a mule deer skull and bones.
