Diet is a major driver of hominin evolution, but most of the geochemical evidence relies on carbon isotopes (δ13C). Here, we report enamel stable calcium isotope (δ44/42Ca) values against δ13C values for several hominins and co-existing primates in the Turkana Basin area, circa 4 to 2 Ma.Australopithecus anamensisclusters with mammal browsers,Kenyanthropus platyopsis distinct fromA.anamensisin foraging into more open environments and the coexistingTheropithecus brumptiencompasses both the grazer and omnivore/carnivore domains. EarlyHomois remarkable for its wide distribution in δ44/42Ca values, possibly reflecting omnivorous and opportunistic preferences.Paranthropus boiseiis uniquely distributed in the δ13C versus δ44/42Ca iso-space being distinct from all other hominins from the Turkana Basin area as well as from the co-existingTheropithecus oswaldi. Several hypotheses are explored to discuss the unique δ44/42Ca values ofParanthropus boiseiincluding significant differences observed with δ44/42Ca values recently reported forP.robustusfrom South Africa, questioning the monophyly of this genus.
