Possible cave hyena humerus

[D.N.FossilmanLithuania]

Dear Guys,

Today I found one very interesting piece of bone, I think it is humerus of big carnivorous mammal like hyena. 

The size of bone is 10,3 cm length and 6,5 cm in the articular part.

If it would be Cave hyena, it would be very rare find, my country belongs to Baltic States, Eastern Europe.

The age of sand layers in my area is about 10- 13 thousand years.

Please help with ID

 

Best Regards
