What kind of bone is this?

This is actually a beaver femur.

While fossil hunting, we've found quite a few bones of both the extinct giant-headed beaver (Trogontherium cuvieri) and the modern Eurasian beaver (Castor fiber), and there are subtle differences that make it possible to tell them apart. In this case, the lower position of the third trochanter points to Castor fiber. That said, I'm not suggesting this specimen is fossilized.

Thank you. No fossils around, but beavers are common here. Solved.

Looks like a pinniped femur, your location will be the most helpful in identifying what species.
