Found a bone.

[One]

Hello everyone,

While I was searching in a swamp I found a bone, a "femur" it looks very old, is there a possibility it used to be from a human?

Size:
Length: 18 cm (7 inches)
Outline on the narrowest part: 5cm (2 inches)

Looks like a fawn femur.

This is an adult deer femur.

Could make sense, a couple of years ago there used to be deers near that swamp.
Although the left part (3th picture) looks way sharper than pictures of a deer femur.

Not a human femur bone. Human femur is a "ball and socket joint" at the hip. Bottom edge connected to patella via ligaments, doesn't fit the shape there either.
