Suzhousaurus is a genus of therizinosaurid dinosaur from the Early Cretaceous Period. It was discovered in the Xinminpu Group of the Yujingzi Basin, Gansu, China. It was described by Li et al., who performed a cladistic analysis and found that Suzhousaurus is more derived than Beipiaosaurus and Falcarius, less derived than
Alxasaurus and true therizinosaurids, and a relative of Nothronychus.
Suzhousaurus is one of the largest known Early Cretaceous therizinosaurids, along with Nanshiungosaurus. It is known from two partial skeletons, including a distinctive upper arm that establishes it as a therizinosaurid.
