Hace 1 día · The largest ornithopods were the hadrosaurids Shantungosaurus, a late Cretaceous dinosaur found in the Shandong Peninsula of China, and Magnapaulia from the late Cretaceous of North America. Both species are known from fragmentary remains but are estimated to have reached over 15 m (49 ft) in length [167] [168] and were likely the heaviest non-sauropod dinosaurs, estimated at over 23 tonnes.
