Abstract
ABSTRACT Late Cretaceous Laurasia contained a typical dinosaur fauna consisting of herbivorous hadrosaurids, ceratopsians, and carnivorous tyrannosauroids. Previously, tyrannosauroid teeth have been found in the Upper Cretaceous Dalangshan Formation of Sihui City, China. We describe a fragmentary skeleton of a duck-billed dinosaur from the same general region. The skeleton includes dorsal and caudal vertebrae, a humerus, ilium, femur and tibia. Morphological comparison and cladistic analyses support that this specimen belongs to the tribe Lambeosaurini, which is otherwise poorly represented in China. The new specimens and the previously discovered tyrannosauroid teeth represent the dominant taxa of the typical Late Cretaceous dinosaur fauna of Laurasia.
