Abstract: In 1933, Black et al subdivided the deposits in the cave into 3 different regions: the Main Deposit, the Lower Fissure and the Kotzetang. From then on, however, some controversies regarding the correlation of different strata in the three regions have arisen. Specifically, the first skull of Peking Man, which was definitely unearthed from the Lower Fissure, has always been virtually located in two different layers of the Main Deposit.
Lin Shenglong recently published a paper proposing the stratum bearing the first skull of Peking Man be correlated with layer 11 of the Main Deposit. However, based mainly on the original reports in the 1920s and 1930s, we have readily come to an otherwise conclusion by employing the principles of stratigraphy. As a result, we tentatively propose here that it would be even more appropriate if the SE stratum was correlated with layer 10 of the Main Deposit.
