Thick molar enamel is among the few diagnostic characters of hominins that are measurable in fossil specimens.

Despite a long history of study and characterisation of Paranthropus molars as relatively "hyper-thick," only a few tooth fragments and controlled planes of section (designed to be proxies of whole-crown thickness) have been measured.

Here we measure molar enamel thickness in Australopithecus africanus and Paranthropus robustus using accurate microtomographic methods, recording the whole-crown distribution of enamel.
