英文摘要	辽宁西部凌源大王杖子义县组恐龙皮肤印痕化石的发现,是热河生物群中恐龙皮肤鳞片的又一次记录.这些鳞片的形态以不规则多边形为主、互不叠覆,同时鳞片的大小、排列方式等随其着生部位的不同而明显变化.从与该皮肤鳞片保存在一起的数枚上颌齿及部分前后肢骨来判断,这一恐龙化石应归鸟臀类,且极有可能为鹦鹉嘴龙类(psittacosaurids).; 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.; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 2; 170-; 50
