A bizarre-looking toothless dinosaur that had only two fingers and would have resembled a giant parrot has been unearthed in Mongolia.
Researchers from Edinburgh found multiple, complete skeletons of the new omnivorous species — dubbed Oksoko avarsan — in the Gobi Desert.
O. avarsan — which lived some 68 million years ago — would have grown to around 6.5 feet (two meters) in length and sported both feathers and a toothless beak.
The team said that the remarkably well-preserved fossils provided the first evidence of digit loss in the typically three-fingered family of dinosaurs known as oviraptors.
The fact that a member of the genus could evolve forelimb adaptations suggests that the group could alter their diets and lifestyles — allowing them to flourish.
'Oksoko avarsan is interesting because the skeletons are very complete,' said paper author and palaeontologist Gregory Funston of the University of Edinburgh.
'The way they were preserved resting together shows that juveniles roamed together in groups,' he added.
'But more importantly, its two-fingered hand prompted us to look at the way the hand and forelimb changed throughout the evolution of oviraptors — which hadn't been studied before.'
