- Isotopic evidence for dietary variability in the early hominin Paranthropus robustusMatt Sponheimer
Department of Anthropology, University of Colorado at Boulder, Boulder, CO 80309, USA
Science 314:980-2. 2006..8 million years ago, savanna-based foods such as grasses or sedges or animals eating these foods made up an important but highly variable part of its diet...
- Tracking changing environments using stable carbon isotopes in fossil tooth enamel: an example from the South African hominin sitesJulia A Lee-Thorp
Department of Archaeological Sciences, University of Bradford, BD7 1DP, UK
J Hum Evol 53:595-601. 2007..Mean (13)C/(12)C for large felids also mirrored this trend...
- Stable isotopes in fossil hominin tooth enamel suggest a fundamental dietary shift in the PlioceneJulia A Lee-Thorp
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..Since new isotopic evidence from Aramis suggests that it was not present in Ardipithecus ramidus at 4.4 Ma, we suggest that the origins lie in the period between 3 and 4 Myr ago...
- Contributions of biogeochemistry to understanding hominin dietary ecologyJulia Lee-Thorp
Archaeological Sciences, University of Bradford, Bradford BD1 7DP, UK
Am J Phys Anthropol . 2006..Nevertheless, we argue that more contextual data from modern ecosystem and experimental studies are needed if we are to fully realize their potential...

Institute of Human Evolution and School of Geosciences, University of the Witwatersrand, Private Bag 3, PO Wits 2050, Johannesburg, South Africa
J Hum Evol 53:602-19. 2007..The Gladysvale Cave fill sediments may serve as a climatically forced chronostratigraphic model for these less well-stratified and well-dated Plio-Pleistocene sites...
- Timing of C4 grass expansion across sub-Saharan AfricaLoïc Ségalen
Department of Archaeology, University of Cape Town, Rondebosch 7701, South Africa

- Inter- and intrahabitat dietary variability of chacma baboons (Papio ursinus) in South African savannas based on fecal delta13C, delta15N, and %NDaryl Codron
Quaternary Research Centre, University of Cape Town, Rondebosch 7701, South Africa
Am J Phys Anthropol 129:204-14. 2006..These data suggest that chacma baboons adapt their dietary behavior so as to maximize protein intake, regardless of their environment...
- The carbon isotope ecology and diet of Australopithecus africanus at Sterkfontein, South AfricaNikolaas 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...
- Insights from stable light isotopes on enamel defects and weaning in Pliocene herbivoresTamara A Franz-Odendaal
Department of Zoology, University of Cape Town, South Africa
J Biosci 28:765-73. 2003..This study reiterates the value of stable isotope analyses in determining both the behaviour of fossil animals and the environmental conditions that prevailed during tooth development...

Department of Biology, University of Utah, Salt Lake City, Utah, USA
Comp Biochem Physiol A Mol Integr Physiol 136:27-34. 2003..Here we discuss which C(4) resources were most likely consumed by australopithecines, as well as the potential nutritional, physiological, and social consequences of eating these foods...
