After seeing all the representations of man-made dinosaurs, you developed in your mind the idea that dinosaurs were huge creatures, fierce and equipped by nature in such a way as to be monsters.
A new species of toothless dinosaur with only two fingers on each upper limb has been discovered in the Gobi Desert of Mongolia.
New research could completely change the perception of dinosaurs
Researchers at the University of Edinburgh found more skeletons of the species, called Oksoko avarsan.
The creature had feathers and dates back about a hundred million years; he also had a large, toothless beak.
The team said the discovery could help explain how animals lose their fingers in the process of evolution.
They said the species had one finger less on each forearm compared to its close relatives, suggesting an adaptability that allowed the animals to spread during the late Cretaceous.
This species seems to have been friendly.
Several complete skeletons of feathered omnivorous creatures have been discovered.
The animals, which grew up to two meters long, had a large, toothless beak, similar to the type seen in parrots.
The team said the discovery that dinosaurs could evolve through adaptations of the forelimes also involves a change in diet and lifestyle, including the multiplication and diversification of the species.
Oksoko avarsan, not only did he look delicate compared to his contemporaries, but they were even friendly. The clues to a social trend of young individuals of the Oksoko avarsan species consist in the discovery of the fossil remains of four young dinosaurs resting together.
Dr. Gregory Funston, of the University of Edinburgh’s School of Geosciences, said the discovery indicates how a group of parrot-like animals today thrived more than 68 million years ago.
The study, published in the journal Royal Society Open Science, involved researchers from the University of Alberta and the Philip J Currie Dinosaur Museum in Canada, Hokkaido University in Japan and the Mongolian Academy of Sciences.
