Megadontosaura

Megadontosaura was a species of Spinosaurid native to Australia around 110 million years ago. Unlike Spinosaurus, a closely related Spinosaurid, it was well adapted to walk on its back legs like most non-avian theropod dinosaurs. They were also able to hunt many herbivores such as Muttaburrasauras and sauropods. They were the largest terrestrial carnivorous dinosaurs that ever lived, about 60 feet long and weighed about 12 tons. They might had went extinct due to competition with Megaraptors (a group of carnosaur-like feathery tyrannosaurs).
