Claim: Bubalina (represented today by the genera Syncerus and Bubalus), and Bovina (represented today by the genera Bison and Bos) are both subtribes of Bovina, which have diverged from one and another from a common ancestor around 13.7 million years ago in the Late Miocene, from Tortonian to Messinian stages about 11.63 Ma (million years ago) to 5.333 Ma.
Evidence: Subtribe: Bubalina
