Abstract: The article deals with the eruption sequence in the mandibular permanent teeth of Lufengpithecus. Eruption sequence here means the order of appearance of the tooth crown out of the alveolar cry pt. Sequences of permanent dental development of 4 sub-adult mandibles are analyzed on the basis of the records of the stages of incomplete crown, root formation, position of the crown occlusal surface relative to the alveolar margin, attrition of the erupted tooth. The eruption sequence in the mandibular permanent teeth of Lufengpithecus can reasonably be inferred as M1Ⅰ 1Ⅰ 2 M2 P3 P4 C M3 . This sequence is similar to that of the modern apes.

Key words: Eruption sequence of mandibular teeth, Lufengpithecus
