Dino LessonAlxasaurus is a therizinosauroid theropod dinosaur from the Early Cretaceous of Mongolia. Several specimens are known and they vary in size, but its maximum adult length is estimated up to 4 m and mass up to 400 kg. Alxasaurus is among the earliest known members of the Therizinosauroidea, but it already possessed the body shape, including the long neck, short tail, and relatively large claws, of later therizinosauroids. Like other members of this group, it was a bipedal herbivore with a large gut to process plant material.
