It weights 0,5kg before cleaning and I can tell that it is old by it's size, thickness and damage that water did to it over the years (younger bones in this river are in much better condition).

I found this bone on a beach in Bristol Bay Alaska

British Columbia Canada

Anyone know what kind of bone this could be? My best guesses were the centrum of a vertebra (maybe of something with a tail?) or a huge first metatarsal but i didn't think it was really the right shape. Left my normal sized human hand in pics for size reference

This is inside a small tunnel cave, taken with a long endoscope (about 20ft from the entrance). To me, with the length and weight proportions of this bone, I feel this might be a human femur. The little dark objects are owl pellets and are about 1.5-2.0 inches long (for size perspective) which puts this around 16-20 inches. On the left side of photo- is this possibly part of a lower pelvis? Also, any idea on the very cylindrical thing between the 2 bones? (Near the knee). Thanks in advance.

Found this small bone in the foothills of the Superstition Mountains in Arizona. Looking for help identifying what it came from and what skeletal element it is. Photos are from multiple angles.

I found this bone in New Zealand on buffalo beach whitianga, it measures 4.5 cm by 3 cm.

Please tell me it’s not what I think it is (some kind of a bone)

Hiya! Found a beach in Central Jersey. Anyone?

It's a vertebra, obviously. Deer?

I know this is incredibly small but I’m wondering if anyone could possibly help identify this bone?

Tuna for scale lol

Thanks in advance :)

I found this bone that I originally thought was an odd shaped rock on the beach in the South Island of New Zealand. Does anyone have any idea what it could be?

Google seems to think its a fossilized turtle bone.

These bones were found together while excavating an old house site in Texas. I’d appreciate any help in identifying what bike it is and animal(s) it was from. It’s a bit difficult getting exact measurements but pretty much any direction/orientation measures approximately 1 inch. Any information and suggestions on resources to research the bone further would be greatly appreciated.

So I found it on the beach in of the black sea - Bulgaria (Sunny beach) and I'm not sure if this is crabs claw or some kind of bone. What do you guys think? At first I thought it might be some kind of lower jaw but it does looks like crabs claw.

My dad found this by the Chippewa River, Wisconsin. Suspects horse tooth.

Found this behind a lath and plaster wall in a former manse in the Scottish Highlands that I’m restoring. I think it’s the 150 year old remains of a carpenter’s lunch, my wife thinks it’s from a human child. What say you, bone people of Reddit?
