Abstract: The present paper is a report on the new discovery of fossil human and associated mammal fauna from the limestone Mawokou Cave in Bijie, Guizhou Province in south-western China. Pleistocene mammal was firstly discovered there in 2008. Three human isolated teeth, one upper canine and two upper molars, were discovered during the excavation in 2013, in the sandy-clay layer of fluvial deposit, associated with rich mammal fossils. The human teeth are more comparable to that of anatomically modern Homo sapiens and different from Homo erectus and archaic Homo sapiens both in tooth sizes and morphological traits. More than 4000 associated mammalian fossils teeth were unearthed from Mawokou cave in the excavations of 3 seasons of 2009, 2012 and 2013, and 53 species of mammals, belonging to 8 orders and 20 families and 43 genera, are identified. These species show a typical assemblage of Ailuropoda-Stegodon fauna in Middle-Late Pleistocene in southern China, and a subtropical forest habitat with warm-humid climate. The mammal fauna assemblage and preliminary dating analysis suggest that the geological age of the human fossils from Mawokou Cave is probably late Middle Pleistocene or early Late Pleistocene.
