The newly discovered dinosaurian skin impressions from the Yixian Formation of a quarry near Dawangzhangzi Village, Lingyuan, western Liaoning represent another record of the dinosaurian skin in the famous Jehol Biota. The scales are polygonal, non-imbricating, and their sizes and arrangements obviously vary in different parts of the body. Over the dorsal region of the neck or anterior back, the skin is covered by relatively large and sub-round scales, which are surrounded by small and polygonal scales. According to the preserved maxillary teeth and some limb bones, the animal described here most probably falls within the group of psittacosaurids, but this viewpoint needs further evidences.
