摘要：
The Fossil sacrum of Sterkfontein Sts 14Q (Australopithecus africanus) was compared with 96 human sacrums of known age so as to reveal its growth stage. Robinson (1972) noticed the presence of an immature trait (unfused intervertebral disc between S1 and S2) in this individual which in other respects is supposed to be a fully matured adult. Our study brings us to define a "sub-adult" category corresponding to a class between the ages of 16 to 25 years in modern humans. Sts 14Q had the same state of maturation, which corresponds to a post-pubertal individual which had not finished its growth concerning the sacral breadth and probably the pelvic breadth.
