A newly discovered 6ft lizard that roamed South East Asia from 36-40 million years ago has been named after The Doors singer Jim Morrison.
The choice of name Barbaturex morrisoni is a play on the late frontman's epithet "The Lizard King," the BBC reported.
Higher temperatures at the time are thought to have helped the lizard evolve to its unusual size.
The scientists were surprised to find that the reptile successfully competed for food against mammals.
A team of palaeontologists analysed fossils of the giant reptile and discovered it is the largest plant-eating lizard to have ever existed.
It lived alongside other herbivorous and carnivorous mammals during the Eocene epoch. It was likely to have weighed about 27.2 kg (60 pounds).
The study is published in Proceedings of the Royal Society B.
