Alxasaurus is one of the earliest known members of the superfamily known as Therizinosauroidea ("Therizinosaurs" for short). This is an unusual subgroup of Theropod dinosaurs that were herbivores (ate plants) - most Theropods were carnivores (ate meat). Like other members of Therizinosauroidea, Alxasaurus was bipedal (walked on two legs), had a large gut for processing plant material, and was equipped with a long neck, a short tail, and long claws on its hands. While Alxasaurus has many typical Therizinosaur features, it also shared a number of other features (like a particular bone found in its wrist, known as "semilunate carpal bone") with other non-Therizinosaur Theropods - it was these features that helped scientists to first realize that Therizinosaurs were a subgroup within the Theropods. Alxasaurus is believed to have grown up to about 12 feet (3.8 meters) long, and probably weighed around 2.5 tons. There is, at the time of writing, no direct evidence about whether Alxasaurus had feathers, but we know that its close relative Beipiaosaurus was feathered, so it does possible that Alxasaurus had feathers too.
