Human Dental Microwear From Ohalo II (22,500–23,500 cal BP), Southern Levant [PDF]

, 2007
Dietary hardness and abrasiveness are inferred from human dental microwear at Ohalo II, a late Upper Palaeolithic site (22,500–23,500 cal BP) in the southern Levant.

New model to explain tooth wear with implications for microwear formation and diet reconstruction [PDF]

Proceedings of the National Academy of Sciences, 2015
Significance Dental microwear is among the most common proxies paleontologists use for diet reconstruction. Recent models have suggested that while quartz grit adherent to food produces wear of tooth enamel, softer particles, such as silica phytoliths found in many plants, do not.

Multiproxy approach to reconstruct fossil primate feeding behavior: Case study for macaque from the Plio-Pleistocene site Guefaït-4.2 (eastern Morocco)

Frontiers in Ecology and Evolution, 2023
The genus Macaca belongs to Cercopithecidae (Old World monkeys), Cercopithecinae, Papionini. The presence of Macaca in North Africa is well known from the Late Miocene to the Late Pleistocene.

Tracking Molar Wear in Captive Baboons: Sex and Age Effects Using a Modified Scott Scoring System. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives This study evaluates molar wear progression in a captive baboon population under controlled dietary and environmental conditions. By comparing the dentin exposure ratio (DER) with a newly developed quadrant‐based modification of Scott's dental wear scoring system (Krueger‐Scott method), we evaluate how wear patterns vary by age, sex,

Testing dietary hypotheses of East African hominines using buccal dental microwear data [PDF]

, 2017
There is much debate on the dietary adaptations of the robust hominin lineages during the Pliocene-Pleistocene transition. It has been argued that the shift from C3 to C4 ecosystems in Africa was the main factor responsible for the robust dental and ...

The functional and palaeoecological implications of tooth morphology and wear for the megaherbivorous dinosaurs from the Dinosaur Park Formation (upper Campanian) of Alberta, Canada.

PLoS ONE, 2014
Megaherbivorous dinosaurs were exceptionally diverse on the Late Cretaceous island continent of Laramidia, and a growing body of evidence suggests that this diversity was facilitated by dietary niche partitioning. We test this hypothesis using the fossil

Diet in Mesolithic Europe: New evidence from dental microwear

Internet Archaeology, 2007
Palaeodietary reconstruction is a key to understanding Mesolithic lifeways. Dental microwear analysis is a tool for investigating palaeodiet using microscopic tooth wear patterns.

Almost billfish: convergent longirostry, micro-dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy. [PDF]

J Anat
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Anterior Dental Microwear Texture Analysis of the Krapina Neandertals [PDF]

, 2012
Some Neandertal anterior teeth show unusual and excessive gross wear, commonly explained by non-dietary anterior tooth use, or using the anterior dentition as a tool, clamp, or third hand. This alternate use is inferred from aboriginal arctic populations,
