Help with id on this 15 cm bone

[LeviBess]

Hello, i post here again to see if someone could help me identifying this bone I found at the beach called Les Roches noires in France. It's a 4 km long beach with a sliding coastline with sedimentary deposits. 

 

The bone is heavy and past the "burn-test", in this area I think its Jurassic-Cretaceous layers but I'm not sure, anyway this bone obviously seems more recent than that. I found it jamed in between two rocks near the clay deposits. 

Thanks in advance,

My best guess is domestic dog proximal tibia.

So worst case scenario I brought someone's dead dog home...great. This bone was found in the same place, any thoughts? Could they be the same animal?

Pelvis.  Could be dog, but could be other mammal.  Dog acetabulum (the socket) height is about an inch (2.25 cm).

Thank you for your answer. Okey, so how old would this be you think?  It does not smell anything when i burn it and its heavy (both pièces) . The second bone is 11 cm on the longest aide so its big.But domestic dog..could it even be fossils then?

By size -- the average wolf is larger than the average dog.

The pelvis is a good-size bone, even in a dog.  The 11 cm length of the fragment is not helpful.  Measure the acetabulum as I suggested.

The socket is almost 5 cm, not the same animal then I guess?

Probably not.  But, this is all very sketchy guesswork.  The best thing is to find a comparative collection to match your bones with known species.
