Though it was heavy, Tarbosaurus' powerful leg muscles made it a good sprinter. Tarbosaurus prowled the broken woodland and desert fringes, pursuing lone or vulnerable dinosaurs, or lying in wait to pounce on them. Perhaps the most terrifying of these was Tarbosaurus, an Asian relative of Tyrannosaurus that stood a lofty five metres tall and weighed a whopping five tonnes. The Mongolian desert in the Late Cretaceous was home to fearsome predators. Therizinosaurus may have used its huge claws to pull tree branches towards its mouth in order to feed on the leaves.īut its claws might also have been used for mating displays, and some scientists think they could have been used for defence against attack by predators. Intriguingly, scientists think its huge claws were an adaptation to a vegetarian way of life, rather than deadly weapons. It had a large stomach in order to digest all this tough vegetable matter, giving its belly a characteristic swollen appearance. Therizinosaurus roamed the conifer forests on the edges of the desert, using its long neck to stretch for leaves growing on tall trees. But unlike other theropods, Therizinosaurus was a vegetarian, a quality which also accounts for its strange appearance. This animal was part of a group of dinosaurs called theropods, making it a distant relative of ferocious meat-eaters like Tyrannosaurus and Velociraptor. This creature was the proud owner of the largest claws of all time, which measured around 70 centimetres in length. But none were more astonishingly bizarre than Therizinosaurus. Seventy-five million years ago, the Mongolian desert was home to dinosaurs of all shapes and sizes.
