Mechanics of microwear traces in tooth enamel

Acta Biomaterialia, 2015
It is hypothesized that microwear traces in natural tooth enamel can be simulated and quantified using microindentation mechanics. Microcontacts associated with particulates in the oral wear medium are modeled as sharp indenters with fixed semi-apical angle.

Premolar microwear and tooth use in Australopithecus afarensis

Journal of Human Evolution, 2013
The mandibular third premolar (P3) of Australopithecus afarensis is notable for extensive morphological variability (e.g., metaconid presence/absence, closure of the anterior fovea, root number) and temporal trends in crown length and shape change over its 700 Ka time range. Hominins preceding A.

Incisor microwear, diet, and tooth use in three Amerindian populations

American Journal of Physical Anthropology, 1999
Incisor microwear patterns have been shown to reflect aspects of diet and ingestive behaviors in a wide range of nonhuman primates. While some studies have suggested that anterior dental microwear might be used to infer unusual front tooth use practices in archaeological populations, quantitative work on modern human incisors has thus far been limited.

Tooth microwear and dietary patterns in early hominids from Laetoli, Hadar and Olduvai

Journal of Human Evolution, 1983
Microscopic analysis reveals specific patterns of wear facets on dental crowns in early hominids from Laetoli, Hadar and Olduvai. The analysis of dental microwear patterns provides an important adjunct for determining Australopithecus afarensis and Homo habilis feeding behaviors and therefore provides an additional source of information for ...

Behavioural ecology of Late Pleistocene bears (Ursus spelaeus, Ursus ingressus): Insight from stable isotopes (C, N, O) and tooth microwear

Quaternary International, 2014
Several types of bears lived in Europe during the Late Pleistocene. Some of them, such as cave bears ( Ursus s. spelaeus and Ursus ingressus), did not survive after about 25,000 years ago, while others are still extant, such as brown bear ( Ursus arctos).

New methods of tooth microwear analysis and application to dietary determination of two extinct antelopes

Journal of Zoology, 1993
A separation exists between the tooth microwear of extant ruminant browsers and grazers when examined with new statistical techniques such as the dichotomous, polychotomous and continuous methods. Extant mixed feeders, however, could not be discerned as a distinct group.

Canine and incisor microwear in pitheciids and Ateles reflects documented patterns of tooth use.

American Journal of Physical Anthropology, 2016
ABSTRACTObjectivesPlatyrrhine species differ in the extent to and the manner in which they use their incisors and canines during food ingestion. For example, Ateles uses its anterior teeth to process mechanically nondemanding soft fruits, while the sclerocarp‐harvesting pitheciids rely extensively on these teeth to acquire and process more demanding ...
