中国中部蓝田附近两个地点更新世黄土中发现的直立人骨架化石，其地质时代有很大差异。在公王岭含化石地层中发现的颅骨约有115万年的历史，而在中更新世黄土中的陈家窝地区发现的遗骸约有65万年的历史。测年是基于新的古地磁极性测定和化石在黄土-古土壤序列中的岩石地层位置。我们的研究结果证实，这两个地方都比周口店的第一次占领。蓝田地区人科化石的新年代、古环境和形态特征，对认识亚洲中晚期人科的适应辐射具有重要意义。
Skeletal ramains of Homo erectus found in Pleistocene loess at two sites near Lantian in central China are of greatly different geologic age. The cranium found in the fossil-bearing strata at Gongwangling is about 1.15 myr old whereas the remains found at the Chenjiawo locality in middle Pleistocene loess are about 0.65 myr old. The dating is based on new paleomagnetic polarity determinations and on the lithostratigraphic position of the fossils in the loess-paleosol sequence. Our results confirm that both localities are older than the first occupation of Zhoukoudian. New dates, palaeoenvironmental settings, and morphological features of the hominids from Lantian localities have significant bearing on the understanding of adaptive radiations of the middle and late hominids in Asia.
