Research Laboratory for Archaeology, Dyson Perrins Building, South Parks Road, Oxford OX1 3QY, UK
Philos Trans R Soc Lond B Biol Sci 365:3389-96. 2010

- Inter- and intrahabitat dietary variability of chacma baboons (Papio ursinus) in South African savannas based on fecal delta13C, delta15N, and %N
Quaternary Research Centre, University of Cape Town, Rondebosch 7701, South Africa

- The carbon isotope ecology and diet of Australopithecus africanus at Sterkfontein, South Africa
Nikolaas J van der Merwe
Archaeometry Research Unit, Department of Archaeology, University of Cape Town, 7701 Rondebosch, South Africa
J Hum Evol 44:581-97. 2003
..Suggestions that more than one species have been incuded in this taxon are not supported by the isotopic evidence. We conclude that Australopithecus africanus was highly opportunistic and adaptable in its feeding habits...
