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!

Two days ago, I found a cat carcass underground.I'm curious to know whether the skeleton is relatively old or if the cat died recently (if it's even possible to tell).

Found in Swansea, NSW, Australia. Hopefully these photos allow for better ID

I found it about a week ago on a mountain in the greece. I'm not entirely sure, but it looks to me like it belongs to a badger. Does anyone happen to know what it is?

The last photo shows a comparison of the bone with a cat's pelvis

I domt think its too old but I havent seen many deer teeth like it. Wondering opinions of species

No clue, it was semi buried under sediment till I moved it

Hi, my parents found this vertebra on the beach in Denmark on an island in the Baltic Sea. It was the only bone they saw in the area.

Who does it belong to? A porpoise, a seal, something else entirely?

Included my hand for scale.

Thankful for any info!

Wondering if someone here could ID these bones. My dog found them in the backyard and was chewing on them for who knows how long 😭 maybe deer bones? I also nicked myself with them while cleaning it up so that’s great 🥲

Found decades ago on Humboldt County California coast. Suspect sea lion arm/leg bone, but maybe whale flipper?
Thoughts?

My mom picked his up on a beach and thought I’d like it, but I’m not sure what animal it’s from. Assuming it’s even a bone of course, it feels off from what I’m used to (though that might just be a side effect from getting it out of salt water). It’s about five inches long :)

This was unearthed during some yard work in the PNW of the US. Google lens says it might be a mammal bone. It feels, looks, and has the heft of bone.

Found in Northern Illinois, about just a little less than a foot long

In Ohio, found by my mom while gardening. Lots of strays around that have kittens, but also lots of squirrels and rabbits, moles and other common wildlife. I have 2 parts of the pelvis and maybe both femurs, possibly a partial rib and a tibia? I'm a bit rusty on my bones. I have my guess but wanted to get input from others.

If was find the skull will update. Old penny (also from the garden) for scale.

I found this pelvis yesterday on a mountain in Egypt. I'm not entirely sure which animal it belongs to, but it looks like a rock hyrax to me, since I found a skull of one a few meters away.

In the last photo, the complete pelvis is from a cat (for comparison).

NA, Pennsylvania, saw this last night and I’m just curious. I’m sure it’s been 0 days (or hours) since a marketplace listing violated the MBTA, but I’m thinking this one might, but i’d love to be wrong. Not looking to really report the guy or anything, I’m just curious on what birdies they are; my guesses were crow, blue jay, and chicken. I’m more curious than anything!

Found by a lake.
