A peculiar dinosaur species has been discovered in the vast expanse of Mongolia's Gobi Desert. This newfound creature has left scientists baffled with its unique two-fingered claws. The claws are not just any ordinary claws. They are massive, measuring nearly a foot in length, and are covered in a protective sheath made of keratin. This sheath is a big deal because it is rarely found intact with dinosaur fossils.

The dinosaur has been officially named Duonychus tsogtbaatari. The name is a nod to Mongolian paleontologist Khishigjav Tsogtbaatar. The genus name, Duonychus, is derived from Greek and means "two claws. " This dinosaur is part of a group known as therizinosaurs. Unlike their more famous cousins, the Tyrannosaurus rex, therizinosaurs were not meat-eaters. Instead, they were likely plant-eaters or omnivores.

Duonychus tsogtbaatari was a towering figure in its time, standing about 10 feet tall and weighing around 573 pounds. Its claws were likely used for more than just grabbing food. They could have been used for defense or even for showing off to potential mates. The claws' shape and size suggest they could grasp branches up to 4 inches in diameter, making it easier for the dinosaur to reach vegetation.

The fossil of this dinosaur was found several years ago by staff at Mongolia’s Institute of Paleontology. Besides the claws, parts of the dinosaur's backbone, tail, hips, arms, and legs were also discovered. The preservation of the claw's keratinous sheath is particularly exciting. It provides a rare glimpse into the relationship between the claw's outer covering and the underlying bone.

The discovery of Duonychus tsogtbaatari has sparked interest among paleontologists. They are eager to learn more about this unique dinosaur and its place in the prehistoric world. The dinosaur's claws, with their distinctive shape and size, have been compared to those of a sloth. This comparison highlights the dinosaur's likely arboreal lifestyle, using its claws to navigate trees and reach food.

The dinosaur's claws have also been likened to barbecue tongs, emphasizing their size and unique structure. This comparison, while humorous, underscores the dinosaur's unusual appearance and the challenges it faced in its environment. The discovery of Duonychus tsogtbaatari is a reminder of the endless possibilities that lie hidden in the earth, waiting to be uncovered.
