True grit: A microwear experiment
American Journal of Physical Anthropology, 1983AbstractRecently we noted the effects of experimental diets on microscopic dental wear in the American opossum and concluded that it might prove difficult to distinguish the microwear produced by an insectivorous diet from that produced by some kinds of herbivorous ones.

Dental microwear texture and anthropoid diets
American Journal of Physical Anthropology, 2012AbstractDental microwear has long been used as evidence concerning the diets of extinct species. Here, we present a comparative baseline series of dental microwear textures for a sample of 21 anthropoid primate species displaying interspecific and intraspecific dietary variability.

A silicon surface and a diamond-like carbon film were scanning scratched in the air. The silicon surfaces scratched with a light load upheaved immediately. This upheaval represents the pre-stage of wear. The silicon surface depressed by heavier scratching began to upheave after some time.

The quantification of microwear polishes
World Archaeology, 1985Abstract In the existing methodology of microwear analysis, both the descriptions and the comparisons of observed traces are highly subjective, which is unsatisfactory from many points of view. The authors describe various image processing techniques and discuss their potential to alleviate this situation by providing a means of quantifying microwear ...

Effect of taphonomic processes on dental microwear
American Journal of Physical Anthropology, 1999Taphonomic processes have the potential to affect microscopic wear on teeth and to modify the wear patterns so as to confound dietary reconstructions based on dental microwear which was formed during the lifetime of an animal. This study describes a series of experiments which were conducted to simulate various taphonomic agents and to record their ...

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 ...

Dental microwear and diet in Venezuelan primates
American Journal of Physical Anthropology, 1992AbstractRecent microwear analyses have demonstrated that wear patterns can be correlated with dietary differences. However, much of this work has been based on analyses of museum material where dates and locations of collection are not well known. In view of these difficulties, it would be desirable to compare microwear patterns for different genera ...

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 of living Hadza foragers
American Journal of Physical Anthropology, 2019AbstractObjectivesStudies of dental microwear of bioarchaeological assemblages and extant mammals from museum collections show that surface texture can provide a valuable proxy for reconstructing diets of past peoples and extinct species. However, no study to date has focused on occlusal surface microwear textures of living hunter‐gatherers.

Microwear mechanisms of coatings
Surface and Coatings Technology, 1995Abstract Microwear mechanisms of coatings are studied by focusing attention on mechanical wear. Wear rates and wear modes of chemically vapour-deposited TiN and Al2O3 coatings in abrasive sliding are observed experimentally with a scanning electron microscope which has a videotape recording system and a tribosystem.
