Reconstructing the diets of extinct hominins is essential to understanding the paleobiology and evolutionary history of our lineage. Dental microwear, the study of microscopic tooth-wear resulting from use, provides direct evidence of what an individual ate in the past. Unfortunately, established methods of studying microwear are plagued with low repeatability and high observer error. Here we apply an objective, repeatable approach for studying three-dimensional microwear surface texture to… 
Dental microwear differences between eastern and southern African fossil bovids and hominins
TLDR
The results imply that differences in microwear reflect diet rather than grit load, and that microwear can provide valuable information not just about environmental dust level, but about food preferences of fossil vertebrates.
Dental microwear texture analysis and diet in the Dmanisi hominins.
Buccal dental microwear variability in extant African Hominoidea: taxonomy versus ecology
TLDR
The results suggest that ecological adaptations at subspecies or population level account for differences in microwear patterns, which are attributed to habitat and ecological conditions within populations rather than differences between species.
Dental microwear texture analysis of two families of subfossil lemurs from Madagascar.
Dental microwear texture and anthropoid diets.
TLDR
The utility of dental microwear texture analysis is reaffirmed as an important tool in making dietary inferences based on fossil primate samples because of significant contrasts between species with diets known to include foods with differing material properties.
Can Dental Microwear Textures Record Inter-Individual Dietary Variations?
TLDR
Microwear 3D scale-sensitive fractal analysis does detect differences in diet ranging from the inter-feeding styles scale to the intra-population between-season and between-sex scales and is therefore a possible tool in the further exploration of the feeding biology and ecology of extinct mammals.
A molar microwear texture analysis of pitheciid primates
TLDR
It is demonstrated that the pitheciids with different morphological adaptations and dietary reliance on seeds differ in their dental microwear textures, though less than initially hypothesized, show potential for identifying dietary variability.

Early hominid diets from quantitative image analysis of dental microwear
TLDR
The results suggest that Paranthropus ate substantially more hard food items than Australopithecus, and the first combined use of image processing and other quantitative techniques to analyse the dental microwear of early hominids is reported.

TLDR
The results of an SEM survey of microwear patterns found on occlusal enamel of chimpanzee molars show that microwear within a single species may vary because of factors that are more to biomechanics than to diet.
Quantification of dental microwear by tandem scanning confocal microscopy and scale-sensitive fractal analyses.
TLDR
A new approach to the analysis of dental microwear using tandem scanning confocal microscopy and scale-sensitive fractal analyses is described, which eliminates major sources of error and increases power to resolve differences between species.

TLDR
A review of dental microwear and diet in modern mammals, plus a discussion of topics for further research are presented, encouraging and may lead to further insights into a variety of topics including food processing and dental microstructure.

TLDR
This study quantitatively examined molar microwear in nine species of extant small-bodied faunivorous primates and microchiropterans and indicated that although insectivores and carnivores could not be distinguished by microwear analyses, hard-object faunvores can be readily distinguished from soft-objectfaunivores.

Interpreting the diet of extinct ruminants: the case of a non-browsing giraffid
TLDR
Quantitative analyses of the microscopic wear patterns on the molars reveal significant differences between three modern species from the three dietary groups and suggest that this extinct giraffid was a grazer, although it cannot rule out the possibility that it was an intermediate feeder.
Error rates in dental microwear quantification using scanning electron microscopy.
TLDR
It is suggested that a consistent technique, such as offered by the Microware software package, be adopted by current researchers to establish a common microwear database, and the margin of intra- and interobserver error should be taken into account when defining pattern differences between populations or when documenting seasonally mitigated differences within a taxon.
Hardness of cercopithecine foods: implications for the critical function of enamel thickness in exploiting fallback foods.
TLDR
It is suggested that it is the difference in the mechanical properties of fallback foods during critical periods that may have served as the selective pressure for thick enamel in L. albigena.
