Dental microwear and diets of African early Homo
Journal of Human Evolution, 2006Conventional wisdom ties the origin and early evolution of the genus Homo to environmental changes that occurred near the end of the Pliocene. The basic idea is that changing habitats led to new diets emphasizing savanna resources, such as herd mammals or underground storage organs. Fossil teeth provide the most direct evidence available for evaluating

Dental microwear and dental function
Evolutionary Anthropology: Issues, News, and Reviews, 1994AbstractInvestigators have used many techniques to understand diet and tooth use in prehistoric species. A promising new addition to the analytical arsenal is dental microwear analysis—the study of microscopic wear patterns on teeth. On‐going work is proceeding on a number of fronts.

Buccal dental microwear texture and catarrhine diets
American Journal of Physical Anthropology, 2017AbstractObjectivesTwo‐dimensional dental microwear analyses on occlusal and nonocclusal enamel surfaces have been widely applied to reconstruct the feeding behaviors of extant primates and to infer ecological adaptations in fossil hominins. To date, analyses of dental microwear texture, using three‐dimensional, Scale‐Sensitive Fractal Analysis ...

A new specimen and dental microwear in Oreopithecus bambolii
HOMO, 2003The authors describe a new specimen of Oreopithecus bambolii, a catarrhine primate from late Miocene sites of Tuscany and Sardinia (Italy). Microwears of 4 specimens of Oreopithecus bambolii have been analysed on standard surfaces of facet 9 to determine the diet.

Microwear and morphology: Functional relationships between human dental microwear and the mandible
Journal of Human Evolution, 2006Microscopic pits and scratches form on teeth during chewing, but the extent to which their formation is influenced by mandibular morphology is unknown. Digitized micrographs of the base of facet nine of the first, second, and third mandibular molar were used to record microwear features from an archaeological sample of modern humans recovered from ...

Hominoid Dental Microwear: Complications in the Use of Microwear Analysis to Detect Diet
Journal of Dental Research, 1984Analysis of dental microwear on chimpanzee molars reveals much variation that reflects jaw mechanics and occlusal function rather than diet. Observed microwear pattern differences relate to variations in molar position, facet type, and overall age of the tooth. Gradients in the amounts of shear and compression generated at different points in the molar

Dental microwear texture analysis and diet in the Dmanisi hominins
Journal of Human Evolution, 2011Reconstructions of foraging behavior and diet are central to our understanding of fossil hominin ecology and evolution. Current hypotheses for the evolution of the genus Homo invoke a change in foraging behavior to include higher quality foods. Recent microwear texture analyses of fossil hominin teeth have suggested that the evolution of Homo erectus ...

Dental microwear of extant Lutrinae
Biological Journal of the Linnean SocietyAbstract Few living mammals are as exemplary of a semiaquatic lifestyle as otters, exhibiting a diverse array of ways that an animal can use water and land resources similar to the way other clades, such as cetaceans or pinnipeds, may have used their habitats during the transition from terrestrial to aquatic life.

The role of food stiffness in dental microwear feature formation
Archives of Oral Biology, 2016The etiology of dental microwear is incompletely understood, despite copious documentation of wear patterns from wild and captive specimens across numerous vertebrate taxa. Among the contested issues with respect to microwear formation is the question of whether materials softer than enamel (specifically, foods themselves) can produce wear features.We ...

Gross Dental Wear and Dental Microwear in Historical Perspective
1998The wearing away of the tooth surface during the chewing of food is a natural process to which the teeth have continuously adapted since even before they were used by Devonian fish. Since then, teeth have been altered in growth pattern, size, morphology, and structural integration of dentine and enamel to accommodate the various diets exploited over ...
