It was about 2.3 metres (7.5 ft) long and resembled a dolphin. It had long jaws with interlocking teeth that jutted to the outside, remaining visible when the jaws were closed, like those of a gharial.In the back of the mouth it had triangular teeth similar to those of earlier cetaceans, but in most other respects, it was relatively advanced."@en . . .
