Scientists unveiled today an extinct species of toothless, whiskered and objectively cute mini-dolphin that plied Earth's oceans some 30 million years ago. With only a fossilised cranium -- found in a river near Charleston, South Carolina -- to work with, the researchers were able to reconstruct the snub-nosed mammal's evolutionary saga, describe its facial features and figure out what it snacked on. Just over a metre (three feet) from snout to tail, Inermorostrum xenops was half the size of the common bottlenose dolphin.
