Australopithecus robustus are early hominids from Africa. The molar size is assumed to be larger in males than female, these data can therefore be used with a mixture model in a study on sexual dimorphism.
'robustus' is a vector with 36 observations on the breadth (mm) of the lower first molar of Australopithecus robustus.
