It was found by Father Emile Licent in 1925 in the Nihewan Formation (dated at about 1.8 Ma) of Hebei Province. On the basis of the minimum circumference of the shaft, a mass of 300 kg, twice that of a modern ostrich, was obtained. The bone is remarkably robust, more so than the femur of the more recent, Late Pleistocene, Struthio anderssoni from China, and resembles in that regard Pachystruthio Kretzoi, 1954, a genus known from the Lower Pleistocene of Hungary, Georgia and the Crimea, to which the Nihewan specimen is referred, as Pachystruthio indet.

Here we describe an ostrich femur, collected in the 1920s and kept in the paleontology collection of the Muséum National d’Histoire Naturelle (Paris, France). Although this bone is poorly preserved, a body mass estimate based on its circumference shows that it belonged to a giant ostrich, significantly larger than the living Struthio camelus.

  • Mammalia: Bovidae) from the Late Miocene Qingyang Area, Gansu, China
    Palaeontologia Electronica palaeo-electronica.org “Gazella” (Mammalia: Bovidae) from the late Miocene Qingyang area, Gansu, China Yikun Li, Qinqin Shi, Shaokun Chen, and Tao Deng ABSTRACT The rich collection from the late Miocene sediments from the Qingyang area, Gansu, China was discovered by E. Licent in the 1920s, and previous studies focused on the equids and hyaenids whereas little attention was given to the accompanying bovid material. The collection of Bovidae dug up from the Qingyang area and pre- served at Musée Hoangho Paiho, Tianjin, China, is dominated by “Gazella”. We describe and identify two species: “Gazella” paotehensis and “G.” dorcadoides. The nomenclatural issues surrounding those two species of gazelles are reviewed in this paper, and although the questionable mandible illustrated by Teilhard de Chardin and Young in 1931 may be excluded from “G.” paotehensis metrically and morphologically, the species is still considered valid. The subcomplete cranium M 3956, kept at Uppsala Universitet Evolutionsmuseet and studied by B. Bohlin, is selected here as the neotype of “G.” paotehensis, and emended diagnoses are given. Based on previous studies and insights from new material from the Qingyang area, we provide a table summarizing diagnostic morphological characters of “G.” paotehensis and “G.” dorcadoides. Yikun Li.

  • The Dates of the Discovery of the First Peking Man Fossil Teeth
    The Dates of the Discovery of the First Peking Man Fossil Teeth Qian WANG,LiSUN, and Jan Ove R. EBBESTAD ABSTRACT 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. KEYWORDS: Peking Man, Zhoukoudian, tooth, Uppsala University. INTRODUCTION FOUR FOSSIL TEETH IDENTIFIED AS COMING FROM PEKING MAN were excavated by palaeontologist Otto Zdansky in 1921 and 1923 from Zhoukoudian deposits. They have been housed in the Museum of Evolution at Uppsala University in Sweden ever since. These four teeth are among the most treasured finds in palaeoanthropology, not only because of their scientific value but also for their historical and cultural significance.
