(Reichenbach in Carus, 1847)
Zygorhiza ("Yoke-Root") is an extinct genus of basilosaurid early whale known from the Late Eocene (Priabonian, 38–34 Ma) of Louisiana, Alabama, and Mississippi, United States, and the Bartonian (43–37 Ma on the New Zealand geologic time scale) to the late Eocene of New Zealand (43 to 33.9 million years ago).[1]
Specimens reported from Europe are considered Dorudontinae incertae sedis.[2]
Zygorhiza kochii, along with Basilosaurus under the designation "prehistoric whales", is the state fossil of Mississippi.[3]
