Two crania, Nanjing 1 and Nanjing 2, were found in a cave near Nanjing in 1993,and referred to as Homo erectus. In recent years, the distortional Nanjing 2 was restored, the Nanjing 1 was compared, and the highly projecting nasal bones, an unusual feature of Nanjing 1, were explained. The Nanjing 2 is an incomplete calvarium, and preserves cracked frontal, parietal, and occipital bones only. The restored calvarium presents larger parietal bones, a relatively narrow upper scale of occipital bone and a probable larger cranial capacity, and reveals affinities with early Homo sapiens rather than Homo erectus. It is acceptable that the high projection of nasal bones is a feature of adaptation to climate. Furthermore, the capacity of Nanjing 1 was calculated to be 871 ml, which is comparable to that of Zhoukoudian 3 and supports the date 580—620 KaBP for Nanjing 1.
