Abstract: Although the Late Cretaceous lizard fauna of China and Mongolia is relatively well-known, information on Paleocene lizards from the same region is currently limited. Several species of lizards have been reported from the Paleocene Wanghudun and Doumu formations of Qianshan Basin on the basis of fragmentary specimens, namely Agama sinensis Hou, 1974, Anhuisaurus huainanensis Hou, 1974, Anqingosaurus brevicephalus Hou, 1976, Changjiangosaurus huananensis Hou, 1976, Qianshanosaurus huangpuensis Hou, 1974, and Tinosaurus doumuensis Hou, 1974. In this paper, we review all the reported material of these taxa with the aid of new technology, including CT scanning, and according to current views of squamate relationships and classification. Revised descriptions and classifications are given for each taxon, leading to changes in our understanding of faunal composition. This, in turn, reveals greater morphological and ecological diversity among the Paleocene lizards of the Qianshan Basin, including the occurrence of a varaniform (IVPP V 22767), and the reinterpretation of Anqingosaurus as a possible burrower. Further work on the Paleocene Qianshan lizards is ongoing and the discovery of new specimens may help to solve the puzzles these strange lizards have posed. 

摘要： 相对于中国和蒙古晚白垩世较知名的蜥蜴动物群，该地区古新世的蜥蜴研究非常有限。安徽潜山盆地曾报道了古新统望虎墩组和痘母组中的6种蜥蜴：中国飞蜥(Agama sinensis Hou, 1974), 淮南安徽蜥(Anhuisaurus huainanensis Hou, 1974), 短头安庆蜥(Anqingosaurus brevicephalus Hou, 1976), 华南长江蜥(Changjiangosaurus huananensis Hou, 1976), 黄铺潜山蜥(Qianshanosaurus huangpuensis Hou, 1974)和痘母响蜥(Tinosaurus doumuensis Hou, 1974), 但化石材料均较破碎。使用CT扫描技术，在最新的有鳞类分类框架下对这些属种进行了重新研究，修订了上述属种的形态学特征及其分类位置。潜山盆地古新世蜥蜴动物群具有比原认为更高的形态学和生态学分异度，如巨蜥类材料(IVPP V 22767)的发现和对安庆蜥可能为穴居型的新解释。
