Pulaosaurus (meaning "Pulao lizard") is an extinct genus of neornithischian dinosaur from the mid-Jurassic (Callovian–Oxfordian ages) Tiaojishan Formation of Hebei, China. The genus contains a single species, Pulaosaurus qinglong, known from a nearly complete articulated skeleton including the skull and soft tissue impressions. It is one of the only non-avian dinosaurs known to preserve a larynx (voicebox), suggesting it may have made bird-like vocalizations. Pulaosaurus is the first neornithischian named from the Yanliao Biota, though members of this clade have been known from other fossil beds of the same age for much longer.
== Discovery and naming == The Pulaosaurus holotype, IVPP V30936, consists of a nearly complete, immature long specimen including most of the skull and a nearly complete postcranium. It includes bones that are not often preserved in dinosaurs, including the hyoid bone and an ossified larynx, as well as cololites (traces of stomach contents).
