The species, called Duonychus Tsogtbaatari, was unique in a group of dinosaurs called Therinosaurs, who were sitting on the back and usually had three claws.

The dinosaur was of medium size, with an estimated weight of approximately 260 kg. The researchers believe that the long, curved claws of the species and its ability to flex them strongly would have made an effective vegetation.
Therizinosaur were a group of herbivorous or omnivorous teropode dinosaurs who lived in Asia and North America during Cretaceous, which started 145 million years ago and ended 66 million years ago, according to bBC.com.

According to one of the study authors, Dr. Darla Zelenitsky, associate professor at the University of Calgary.
The specimen was recovered from the Bayanshiree formation of the Gobi Desert in Mongolia, dating from the late Cretaceous period (between 100.5 and 66 million years ago).
UNESCO, the United Nations for Education, Science and Culture, calls the Gobi Desert in Mongolia the largest fossil tank in the world.
The region is a very important source of fossils of the last period of Cretaceous, which is the last of the three main periods of the dinosaurs era, representing the final phase of the evolution of the dinosaurs.
The study showed that the claws, almost 30 centimeters long, were much larger than the basic bone.
In addition to a better grasp, the two fingers could have been used as a gesture of domination, digging or as formidable weapons.
The most popular two-fingered terror are the species in the Tyrannosaurid group, which includes Tyrannosaurus Rex, but Duonychus has developed their hands with two fingers separate from them and other two fingers.
Also, the specimen retains the first keratinic coating of a terminosaur, an element that covers the claw just like human nails, helping with defense, movement or catching.
