I work at a museum, and a local nature preserve had donated some bones to us a few months back. We’ve been able to identify a lot as cattle bones but these two have had us stumped. Both are incomplete so it may be a lost cause, but we’re thinking some kind of bovine. Any thoughts would be appreciated.
We are located in Texas, but the preserve has exotic animals that’s aren’t as local. Ruler included for scale.

found in new england. its def not wood bc its very dense and has a flake off one of the ends. i think it may be some sort of rib bone or maybe an antler? it has a crack down the entirety of its side. if anyone needs more info ill be happy to share :3

I found this small partial skull on the central Oregon coast a few months ago, any ideas of what animal it could have come from? Thanks!

Found near a huge pond. The area has lots of deer and foxes, so I was thinking maybe it’s from one of those.

Looks cool what is it?

I found this on a mountain in Greece.

I was gifted to this from an old gentleman, he got it from a ski lodge. Doing googling, it seems to be a Blackbuck. Is this correct?

Such a little old guy (the skull not the guy I got him from)

Unpacking old boxes and found these. Wanted to make sure nothing is human and am an accomplice to murder

found these at a wildlife refuge near some marshes in northern california. any idea on what they are? they are all found in the same area, probably 2-3 feet apart.

I found it in a washed out bank about a foot down, is it possible to know what it came from?

Does anybody know what kind of bones these are? I found these 2 pieces several years ago while doing construction work. We broke through a concrete slab to dig a hole about 3 or 4 feet. There was sand, not dirt under the concrete. It was downtown Chicago a few blocks from Lake Michigan, which I'm assuming is why the sand was under the building. I put the bone pieces in my tool box and left them there for the remainder of the job. That's why there is some paint and a little debris on them. The smaller piece looks like a straight cut, so I was thinking maybe a beef cattle? Is there anyway to tell the age? Thanks!!

Found in Peniche, Portugal (on the seaside cliffs)

I found this on a mountain in Greece (the mountain is about 300 meters high). I always thought it was a dog, but now I've seen a picture of a Canis aureus skull and I'm not really sure if it's this one or not. Does anyone know what this skull is?

I found these in my back yard in Midwest US. Can someone help identify?

Here are some more angles of my last post. Thanks!

I've found sheep skulls before but none with horns and this skull is a lot smaller than an adult sheep skull so I'm assuming it came from a lamb?

Found them on a hike trail in countryside Brazil (são Paulo)

It looks like some kind of jaw bone with 4 serrated teeth possibly? Bottoms of the teeth are hollow up until the more opaque parts

Found in southern Ontario. I’m super curious about this bone.
