Scientists have unearthed a new species of the giant sea lizard mosasaur in Morocco that hunted other marine reptiles about 66 million years ago using its massive jaws and teeth like those of modern-day killer whales.
The giant marine lizard named Thalassotitan atrox, described on Wednesday in the journal Cretaceous Research, grew up to 9m (30 ft) in length and are distant relatives of modern iguanas and monitor lizards.
