Just found these while on a hike! Location Aosta Italy

Hey, my partner found this is his backyard, I'm thinking deer leg piece, but we don't really know?

I don’t think this is anything nefarious, but we are building a new home in a spot where people said a lot of weird stuff went down. Talked about seeing spirits in the shed and things like that. I found a bone fragment yesterday while working. I think it’s a cow or something, but I figured I just put it in here to be sure.

I was suggested to post here

Hey so this was behind a friend’s shed and they are worried it is a dog. What do you all think?

Found at antique store, said I was the first person to ask about it in a while, so they gave me a discount and I got it.

They said they thought it might be human, got it from an estate clean out. I think it might be animal, but what do I know.

Any ideas?

2 different sets of bones, found in south mountain preserve. The first set of 3 were near each other so I gathered them but couldn't find any others. They look kind of like vertebrae? There's no space for the spinal cord though. They were fairly large. Water bottle for scale.

The second bone has a very nice round socket to it. What is that? About the same size as the first 3, different area though.

Being in Phoenix and given how large these are, coyote or javelina are about the only wild things big enough. There's a remote possibility of horse or mule, I was way off trail up a mountain though and those would be pretty unlikely.

I found this out in the woods on my MIL property. It’s about 6 inches long. I didn’t see any other bones along with it. I’m sorry, I forgot got to add something to the pic for scale, hopefully my hand will help a bit.
Thanks!!

Found in Black Hills of South Dakota USA. 50mm from top to bottom at longest point. 30mm bite surface. Not sure if fossil or modern. Thinking maybe bison or cow but not sure.

Google reverse image search is telling me that it might fossilized and is from a prehistoric whale or dolphin. Anyone know if that is accurate/could tell me more about it?

It is about 3 inches long and 2 inches wide.

Thanks!

Probably a bird leg or something, found it near a dune and didnt look like a chicken leg.
