Abstract: A lower jaw bone of deer, very thick, was found from the Salawusu Formation of the Late Pleistocene in Inner Mongolia not long ago (Wei Qi, 1983, p. 93) . Its swelled condition below the middle lobe of Msis similar to that of Megaloceros pachyosteus of Zhoukoudian Locality 1 (Table 1) . It seems that this jaw can be referred to Megaloceros pachyosteus rather than Megaloceros ordosianus. It is possible that Megaloceros pachyosteus survives after the end of the Middle Pleistocene in North China.

Key words: Megaloceros pachyosteus; Late Pleistocene
