Holocene survival of Late Pleistocene megafauna in China: a critical review of the evidence

Late Quaternary megafaunal extinction chronologies are poorly understood across eastern and southeast Asia. Previous radiometric studies suggested that surprisingly many extinct late Pleistocene large mammal species survived into the Holocene in northern China (Bos primigenius, Coelodonta antiquitatis, Mammuthus primigenius) and southern China (Ailuropoda baconi, Crocuta [crocuta] ultima, Megatapirus augustus, Stegodon orientalis, Sus cf. xiaozhu), indicating that Chinese megafaunal extinctions may have been staggered across the Late Quaternary. We critically re-examined all radiometric evidence suggesting Holocene survival of Chinese Late Quaternary megafauna, and conducted new dating of mammal material from reportedly Holocene sites containing characteristically Late Pleistocene faunas. Evidence for Holocene survival of any Chinese Late Pleistocene megafaunal species is weak or untenable. No previous radiometric dates used to support Holocene megafaunal survival represent direct bone dates for species of interest, and stratigraphic association between material yielding Holocene dates and megafaunal remains is dubious at most sites. Concerns over accurate identification of faunal material further confuse claims for Holocene survival of many species. Robust radiometric last-occurrence dates for extinct Chinese megafauna are all restricted to the Late Pleistocene, similar to the timing of many other Late Quaternary megafaunal species extinctions elsewhere in Eurasia and the Americas.
