摘要
本文分析了禄丰古猿不同年龄的次成年下颌标本上各齿种萌发的情况 ,得出其下颌恒齿的萌出顺序为 M1 1 2 M2 P3P4 C M3。这种萌序与类人猿的相一致。
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 crypt.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 M 1Ⅰ 1Ⅰ 2 M 2 P 3 P 4 C M 3.This sequence is similar to that of the modern apes.
