Department of Anthropology, University of Arkansas, Fayetteville, AR 72701, USA
Front Oral Biol 13:38-43. 2009..These results suggest that dental microwear texture analysis can help us determine whether craniodental specializations in fossil species are adaptations to preferred foods, or to less often but still critical fallback items... - Dental microwear and diet of the Plio-Pleistocene hominin Paranthropus boiseiPeter S Ungar
Department of Anthropology, University of Arkansas, Fayetteville, Arkansas, United States of America
PLoS ONE 3:e2044. 2008..The apparent discrepancy between microwear and functional anatomy is consistent with the idea that P. boisei presents a hominin example of Liem's Paradox, wherein a highly derived morphology need not reflect a specialized diet... - Dental evidence for the diets of Plio-Pleistocene homininsPeter S Ungar
Department of Anthropology, University of Arkansas, Fayetteville, AR 72701, USA
Am J Phys Anthropol 146:47-62. 2011..New methods of analysis and theoretical perspectives are improving our understanding of the diets of Australopithecus, Paranthropus, and early Homo, and promise further progress long into the future... - Reproductive fitness and tooth wear: milking as much as possible out of dental topographic analysisPeter S Ungar
