The Dates of the Discovery of the First Peking Man Fossil Teeth

Four teeth of Peking Man from Zhoukoudian, excavated by Otto Zdansky in 1921 and 1923 and currently housed in the Museum of Evolution at Uppsala University, are among the most treasured finds in palaeoanthropology, not only because of their scientific value but also for their important historical and cultural significance. It is generally acknowledged that the first fossil evidence of Peking Man was two teeth unearthed by Zdansky during his excavations at Zhoukoudian in 1921 and 1923. However, the exact dates and details of their collection and identification have been documented inconsistently in the literature. We reexamine this matter and find that, due to incompleteness and ambiguity of early documentation of the discovery of the first Peking Man teeth, the facts surrounding their collection and identification remain uncertain. Had Zdansky documented and revealed his findings on the earliest occasion, the early history of Zhoukoudian and discoveries of first Peking Man fossils would have been more precisely known and the development of the field of palaeoanthropology in early twentieth century China would have been different.
