Eurhinodelphis was around 2 metres (6.6 ft) in length. In most respects, it would have looked like a modern dolphin or porpoise, but its upper jaw was elongated into a sharp tip similar to that of a swordfish. Most likely, Eurhinodelphis used it in a similar manner to swordfish, hitting or stabbing prey. It also had long, sharp teeth.[1] Eurhinodelphis was closely related to the orca-sized Macrodelphinus.
