   The Paleocene world seemed to be a rough world for vertebrates. As concerned with Squamata, the Paleocene fossil record is very patchy outside North America, especially in Asia. The restudy on reported materials and new fossil discovery suggest, actually there is a diverse squamate assemblage from the Early-Middle Paleocene deposits of Qianshan Basin, Anhui, China. The assemblage includes several acrodontans, two varaniforms, one scincoid or lacertoid, and several indeterminate squamates.  

   Compared with the diverse squamate assemblages from the Late Cretaceous, the Qianshan Paleocene squamates, together with squamates from other Asian Paleocene localities, demonstrate that major clades of squamates (Iguania, Anguimorpha, and either Scincoidea or Lacertoidea) survived the K/T mass extinction in this region. The fate of Gekkota remains unclear.
