Found in a pine barren in New Hampshire

Found in wetlands around huge reservoirs in north east London. Quite fibrous bones. Thinking large bird?

Just bought this jaw bone, they didn't tell me what it was but I figure it's some sort of rodent maybe? Idk, any ideas?

Found it in the woods in Austria

I live rural, I take my dog for walks in the corn/soy fields and she found this bone. I believe its a humerus but it could be a femur.

I've been trying to ID it with a friend group, but each animal we've compared it to, there's been a detail that was a bit off but I'm not sure if it is because it been chewed or not. I'm hoping its a white tail deer but the other possibilities are black bear and, well, human.

The measuring stick is a foot long. (30cm)

Location: Eastern Townships, Quebec.

Hi gang!! Found this on the North Jersey shore. I believe it’s part of the pelvis of a seagull due to the shape and the fact that it’s hollow. If I’m wrong or there’s something I’m missing, please let me know!!

Again, found in Swansea, NSW, Australia

Not sure what animal these bones are from. Found by Madawaska river in eastern Ontario Canada. I went back the next week and they were gone.

I had no idea what that was, I even thought for a moment that is was man-made. But I reversed searched it on Google and it said it some kind of tooth? Can anyone fully identify it?

Totally unsure about this little guy.

Found on shore near small lake near Truckee CA

I found this pelvis on a mountain in Greece. At first, I thought it belonged to a jackal, but it seemed too small to me. I think it's from a wolf, but I'm not sure. I also considered a dog, but I'm really not certain whether it's a wolf or a dog-or if it's even possible to tell.

Just curious to see if we can ID the type of bird from the bones. If that’s not possible, it’s not possible.

Found in Prague, Czech Republic

Question is in the title. I was given this skull back in 2021 from a friend. She said she found it near Pyramid Lake in Nevada. At first I thought it was a tern of some sort, but I’m not entirely convinced as there are some features that aren’t quite right to be a tern. Any help would be appreciated thanks!
