The newly discovered dinosaur species Oksoko avarsan most reminiscent of an overgrown, toothless parrot.
With its two meters and its feathered costume, the omnivorous creature lived about 68 million years ago – at the end of the Cretaceous.
In the very first study of this species, which was found in the Gobi Desert in Mongolia, paleontologists have discovered a very special detail.
A detail that can lead to an increased understanding of the history of evolution.
Different from the relatives
Oksoko is part of the oviraptor family. But the “newcomer” stands out in a slightly special way. It has, unlike its relatives, only two fingers.
The oviraptors are known to have three fingers, as the hands and grip properties have been an important tool for obtaining food.
– This was very surprising, says Gregory Funston to NRK. He has been researching the new species for the past six years, and was the first to discover that Oksoko was missing a finger.
The British paleontologist believes that the development took place as a result of the oviraptors spreading across the earth. They have managed to adapt to new places and new climates.
Funston believes the group’s ability to develop and adapt gave them a very special advantage in the battle for survival.
Important part of evolution
At the end of the Cretaceous, several dinosaur species were in sharp decline, but this should not have been the case for the oviraptors.
This dinosaur genus was rather prosperous. They were very numerous before the famous Chicxulub asteroid hit Earth – the asteroid known to have led to the mass extinction of dinosaurs.
Paleontologist Lene Liebe Delsett believes that the newly discovered detail of Oksoko says something about the evolution of dinosaurs at the end of the Cretaceous.
– The dinosaur group to which Oksoko belongs, developed rapidly and spread to many new places during this time. This can teach us about how new adaptations develop and how ecosystems work.
The Gobi Desert in Mongolia, where the dinosaur skeletons of Oksoko were found, is known for housing the fossils of the past. Especially of dinosaurs and early mammals.
Like many other places in the world, this area is also very vulnerable to illegal excavation. The fossils are sold to private players.
This is how the story started Oksoko avarsan. The four skeletons, which British and Mongolian researchers have used in recent years to study, were taken out illegally.
But fortunately, the thieves were stopped before the precious fossils reached the border.
Today, paleontologist Gregory Funston is very grateful for that.
– I had never before witnessed such a complete dinosaur skeleton. The four individuals were found lying together, which may indicate that these young dinosaurs wandered in groups, he says.
Lene Liebe Delsett is just as excited.
– The fossils of Oksoko avarsan are beautiful, imagine they are 70 million years old! Most fossils we find of large animals like this are usually crushed and crushed. Here you can see that the dinosaurs died while lying in a resting position. Maybe they were asleep?
