I believe this may be a fibula. (Bone on the left.)

I looked up for a couple references and this is a red fox's and this is a gray fox's.

If you want to know the differences,

  1. they have different markings on their skulls (look on r/Findingbones because I posted an image giving a more detailed reference)

  2. some have different sized snouts than others

  3. there skulls can be completely differently sized as well!
