Cover Story: A femur found in 1925 by the French naturalist Emile Licent shows that giant ostriches inhabited what is now Northern China some 1.8 million years ago. The specimen comes from the Lower Pleistocene Nihewan Formation of the Nihewan Basin (Hebei, China). It refers to the extinct genus Pachystruthio, hitherto known from Lower Pleistocene localities in Hungary, Crimea, and Georgia, thus much extending the distribution of Pachystruthio eastward. A mass estimate of 300 kg indicates that this Chinese ostrich was twice the weight of the living ostrich Struthio camelus. Pachystruthio was contemporaneous with the early hominins of the Nihewan Basin. View this paper
