Direct comparisons of 2D and 3D dental microwear proxies in extant herbivorous and carnivorous mammals. [PDF]

PLoS ONE, 2013
The analysis of dental microwear is commonly used by paleontologists and anthropologists to clarify the diets of extinct species, including herbivorous and carnivorous mammals.

Testing dental microwear as a proxy for characterising trophic ecology in fossil elasmobranchs (chondrichthyans)

Swiss Journal of Palaeontology
Dental microwear analysis is a well-established technique that provides valuable information about the diets of extant and extinct taxa. It has been used effectively in most major groups of vertebrates.

Inter-microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments.

The Anatomical Record, EarlyView.
Dental microwear texture analysis (DMTA) has become a well-established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods.

Accuracy of dental microwear impressions by physical properties of silicone materials

Frontiers in Ecology and Evolution, 2022
Dental microwear analysis is an oft-used paleodietary estimation method, and the impression molds or resin casts are often analyzed rather than the original tooth surfaces.

Introducing ‘trident’: a graphical interface for discriminating groups using dental microwear texture analysis

Peer Community Journal
This manuscript introduces trident, an R package for performing dental microwear texture analysis and subsequently classifying variables based on their ability to separate discrete categories.

Buccal dental-microwear and dietary ecology in a free-ranging population of mandrills (Mandrillus sphinx) from southern Gabon. [PDF]

PLoS ONE, 2017
Analyses of dental micro- and macro-wear offer valuable information about dietary adaptations. The buccal surface of the teeth does not undergo attrition, indicating that dental microwear may directly inform about food properties. Only a few studies have,

Simulating taphonomic processes on teeth: The impact of sediment pressure and thermal alteration on dental microwear

Quaternary Science Advances
Dietary reconstructions based on dental microwear methodologies may be limited due to the various taphonomic processes that affect the formation of archaeological deposits. These limitations are primarily affected by two issues: 1) taphonomic alterations

Dietary behaviour of man-eating lions as revealed by dental microwear textures [PDF]

Scientific Reports, 2017
Lions (Panthera leo) feed on diverse prey species, a range that is broadened by their cooperative hunting. Although humans are not typical prey, habitual man-eating by lions is well documented. Fathoming the motivations of the Tsavo and Mfuwe man-eaters (

Behavioral strategies of prehistoric and historic children from dental microwear texture analysis

Frontiers in Ecology and Evolution, 2022
IntroductionReconstructing the dietary and behavioral strategies of our hominin ancestors is crucial to understanding their evolution, adaptation, and overall way of life.

‘Do larger molars and robust jaws in early hominins represent dietary adaptation?’ A New Study in Tooth Wear [PDF]

Archaeology International, 2013
Diet imposes significant constraints on the biology and behaviour of animals. The fossil record suggests that key changes in diet have taken place throughout the course of human evolution.
