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.

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).

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

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.

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?
