Deinocheirus is a genus of dinosaur that lived during the Late Cretaceous period around 70 million years ago in what is now Mongolia. The name Deinocheirus means “terrible hand,” referring to its huge, clawed forelimbs. This dinosaur was first described from only its massive arms, which were over 8 feet long and tipped with sharp, curved claws. However, later discoveries of more complete skeletons revealed that it was a large, bipedal animal that could grow up to 36 feet long and weigh as much as 6 tons.
The deinocheirus’s body was long and bulky, with a small head relative to its size and a toothless beak. Its arms were probably used to reach vegetation and scoop it up into its mouth, as it was likely an herbivore.
Despite its fearsome appearance, Deinocheirus was not a predator, and instead likely used its size and strength to defend itself from predators like Tarbosaurus. Deinocheirus is a fascinating dinosaur that continues to intrigue paleontologists with its unique combination of features and mysterious lifestyle.
