I was walking in a forest along an old river. There were beavers on this river, so the water was high at a certain moment. Now the water has receded and I have found this leg. I would like to know if this is human.

Answer
This bone did not come from a human. Human and animal bones are distinguished by shape and by differences in the structure of the compact bone on the outside and the spongy bone on the inside. This bone can be considered animal because this shape does not exist in the human skeleton. A zoologist may be able to tell you which animal it came from.
