On the eruption pattern of the permanent incisors and first permanent molars in Paranthropus

Abstract

It has been claimed recently that Australopithecus exhibited a pattern of permanent tooth eruption like that of extant great apes, whereas a significantly different pattern was shared by Paranthropus and Homo (Dean, 1985). More particularly, each of the four Paranthropus specimens examined in that study was held to show advanced development and eruption of the permanent incisors relative to the first molar. It is demonstrated here that the eruption sequence that was posited for at least one of these four Paranthropus specimens (SK 61) is clearly erroneous, while the developmental/eruption sequences manifested by the other three specimens would appear to be more ambiguous than was claimed. Another juvenile specimen of Paranthropus (KNM-ER 1820) that was not included in Dean's study also does not necessarily support the eruption pattern that was said to characterize that taxon.
