Yuanyanglong

Yuanyanglong (meaning "lovebird dragon") is an extinct genus of oviraptorosaurian theropod dinosaurs from the Early Cretaceous Miaogou Formation of China. The genus contains a single species, Yuanyanglong bainian, known from two partial skeletons.

== Discovery and naming == The Yuanyanglong fossil material, was discovered in 2021 in sediments of the Miaogou Formation (Maortu locality) in the Gobi Desert of Chilantai, Inner Mongolia, China. Two incomplete skeletons were found in association on the same block, which are assumed to represent the same species based on comparable anatomy and body size. The holotype specimen, PV02476-1, consists of the pelvic girdle, the right hindlimb missing the foot, the pectoral girdle, the right forelimb missing the hand, several ribs, and dorsal and caudal vertebrae. The associated referred specimen, PV02476-2, includes an incomplete poorly-preserved skull, partial hindlimb without the foot, incomplete pelvis, several dorsal vertebrae, and a partial sacrum.
