Zygorhiza was a smaller, less elongated, 6 m (20 foot) long relative of the famous Basilosaurus. Zygorhiza had flippers which could, unlike in modern cetaceans, be moved at the elbow. Its hind limbs were rudimentary. Zygorhiza's one-metre (3-foot) skull had fearsome jaws with deadly teeth. Unlike modern cetaceans, Zygorhiza had a neck consisting of seven vertebrae.
