Puma fawn is the largest representative of small cats and the fifth largest feline world (after tiger, lion, jaguar and leopard). Its mass is characteristic of large cats (Panthera), however it is more closely related to small and medium cats. The subfamily of small cats (Felinae) evolved in Asia 11 million years ago. Research on the taxonomy of cats on the remains only partially explains their origin. MtDNA research explained a lot, and because in the fossil record these cats are poorly represented, this is a satisfying result.
