and E. longirostris''
Eurhinodelphis was around 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. Compared with earlier fossil species,
Eurhinodelphis had complex ears, suggesting that it already hunted by
echolocation like modern whales. Its brain was also asymmetrical, a trait found in modern dolphins, and possibly associated with the complexities of navigating its environment. ==History==
