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 ...

A study of microwear on chimpanzee molars: Implications for dental microwear analysis
American Journal of Physical Anthropology, 1982AbstractRecent investigations of dental microwear have shown that such analyses may ultimately provide valuable information about the diets of fossil species. However, no background information about intraspecific variability of microwear patterns has been available until now. This study presents the results of an SEM survey of microwear patterns found

Dental microwear texture analysis: technical considerations
Journal of Human Evolution, 2006Dental microwear analysis is commonly used to infer aspects of diet in extinct primates. Conventional methods of microwear analysis have usually been limited to two-dimensional imaging studies using a scanning electron microscope and the identification of apparent individual features.

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.

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 ...

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.

In vivo and in vitro turnover in dental microwear
American Journal of Physical Anthropology, 1989AbstractGiven the potential usefulness of dental microwear analyses in interpretations of archaeological and paleontological material, it is surprising how little we know about changes in individual microwear features through time. The purpose of this study was to document the turnover in primate dental microwear through in vivo dental studies of ...

AbstractObjectivesThis study seeks to determine if (a) consumption of hard food items or a mixture of food items leads to the formation of premolar or molar microwear in laboratory capuchin monkeys (Sapajus apella) in one feeding session and (b) rates of microwear formation are associated with the number of food items consumed.Materials and methodsFive

On the relationship of dental microwear to dental macrowear
American Journal of Physical Anthropology, 2009AbstractDental microwear analysts have demonstrated that hard diets leave numerous microscopic pits on occlusal surfaces. The relationship between occlusal pitting and gross macrowear, however, is not well known. The current study seeks to elucidate the relationship between dental microwear and macrowear by determining if microscopically pitted teeth ...

Inferences from Quantitative Analysis of Dental Microwear
Folia Primatologica, 1989Tooth microwear studies have been carried out for several reasons in the last decade. Most effort has been put into categorizing wear types that reflect dietary preferences in order to reconstruct the diet of extinct species. Several studies have shown that, for primates, carnivores and ruminants, it is possible to differentiate statistically the ...
