A new specimen of Liaoceratops yanzigouensis is described from Lujiatun Bed of the Early Cretaceous Yixian Formation in Beipiao, western Liaoning. The specimen shows the typical characters of Liaoceratops:three premaxillary teeth; large triangular antorbital fossa; epijugal absent; predentary hooked dorsally; and ventral flange presents along the mandible with several tubercles. New morphological information of the rostral has been revealed through the three-dimensional reconstructions based on CT scanning, the rostral is keeled anteriorly and bears a broad vertical crest along its posterior midline. The postcranial skeleton of Liaoceratops yanzigouensis is described for the first time. The profile and position of the fourth trochanter is possibly valuable for the classification of the basal neoceratopsians.
