New material of large-bodied ornithischian dinosaurs, including an iguanodontian ornithopod, from the Quantou Formation (middle Cretaceous: Aptian–Cenomanian) of Jilin Province, northeastern China
Abstract:The Quantou Formation of Jilin Province, Northeast China, has recently yielded an important new middle Cretaceous (Aptian–Cenomanian) fauna of terrestrial vertebrates, including zalambdalestid mammals, basal ornithopod dinosaurs and basal ceratopsian dinosaurs. Here we describe well-preserved but isolated and fragmentary material of large-bodied ornithischian dinosaurs from this formation. An isolated humerus represents an iguanodontian ornithopod dinosaur, expanding the known stratigraphic and geographic range of this group within China. Other material (partial distal tibia, series of three dorsal vertebrae apparently representing part of a fused synsacrum) can only be assigned to Ornithischia indet.
