Lanzhousaurus is a genus of dinosaur. Lanzhousaurus lived in the Gansu region of what is now China during the Early Cretaceous (Barremian). A partial skeleton has been recovered. It was described by You, Ji and Li in 2005 and the type species is Lanzhousaurus magnidens. [1]


It is perhaps most notable for its "astonishingly huge teeth", among the largest for any herbivorous creature ever, which indicate it is a styracosternan iguanodont. The mandible, longer than one meter, suggests very large size for the animal.
