The newly discovered toothless, two-fingered dinosaur sheds light on how creation evolved 68 million years ago.
A team led by the University of Edinburgh has found multiple skeletons of a new species, the Oksoko Avarsan, in the Gobi Desert in Mongolia.
The feathers and omnivorous creatures grew up to two meters in length, each had only two functional numbers on its wrist, and had a large beak with no teeth similar to that found in parrots today.
The researchers said that the well – preserved fossils provided the first evidence of loss of numbers in the three – fingered family of dinosaurs known as ovipractors.
The team says the discovery that they can develop forelimb adaptations has enabled the group to change their diet and lifestyle and enable them to diversify and increase.
The study was led by a professor at the University of Edinburgh School of Geosciences. Gregory Funston said: “Oxoko Averson is interesting because the skeletons are so complete and the way they are preserved together that the juveniles roll together into groups.
“But more importantly, its two-fingered hand led us to see how the hands and forelegs changed throughout the evolution of previously unreleased aviators.
“It reveals some unexpected trends and is an important part of why aviators were so diverse before the extinction of the dinosaurs.”
Throughout the evolutionary history of ovaries, researchers have studied the reduction and eventual loss of the size of the third finger.
With the migration of new geographical areas, the weapons and hands of the creatures changed considerably, especially now to North America and the Gobi Desert.
The team also found that the oxacho warson, like other prehistoric creatures, was as social as the juveniles.
