Deinocheirus is a genus of large dinosaur discovered in the early 20th century that lived during the late Cretaceous period, approximately 70 million years ago. It is an Oviraptorosaur, a group of bird-like dinosaurs. These creatures were typically bipedal and characterised by long forelimbs, a unique humped sail on their back and feather-like structures. They are primarily known from a pair of gigantic arms found in Mongolia, and due to these long forelimbs, the genus was named Deinocheirus, meaning terrible hand. Complete specimens discovered in recent years have helped scientists to better understand the anatomy and lifestyle of these extraordinary dinosaurs.
