Tooth microwear texture in odontocete whales: variation with tooth characteristics and implications for dietary analysis

open access: yesBiosurface and Biotribology, 2017
Understanding the diets and trophic relationships of toothed whales is central to understanding their roles in marine ecosystems, and associated conservation issues.

Diet in Mesolithic Europe: New evidence from dental microwear

open access: yesInternet 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.

Can dental microwear textures record inter-individual dietary variations? [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Dental microwear analyses are commonly used to deduce the diet of extinct mammals. Conventional methods rely on the user identifying features within a 2D image.

Surface Replication, Fidelity and Data Loss in Traditional Dental Microwear and Dental Microwear Texture Analysis [PDF]

open access: yesScientific Reports, 2019
AbstractDental microwear studies often analyze casts rather than original surfaces, although the information loss associated with reproduction is rarely considered. To investigate the sensitivity of high magnification (150x) microwear analysis to common surface replication materials and methods, we compared areal surface texture parameters (ISO 25178-2)

Dental microwear and diet of the Plio-Pleistocene hominin Paranthropus boisei.

open access: yesPLoS ONE, 2008
The Plio-Pleistocene hominin Paranthropus boisei had enormous, flat, thickly enameled cheek teeth, a robust cranium and mandible, and inferred massive, powerful chewing muscles. This specialized morphology, which earned P. boisei the nickname "Nutcracker

Lifestyle changes and its effect towards the evolution of human dentition

open access: yesEgyptian Journal of Forensic Sciences, 2022
Background The dentition of modern humans has evolved from their hominid ancestors to their current form. Factors regarding the changes of lifestyle such as dietary habits and usage of tools have affected the evolution of human dentition.

Diet reduces the effect of exogenous grit on tooth microwear

open access: yesBiosurface and Biotribology, 2020
Exogenous grit adherent to the surface of food items and food fracture properties have each been considered important factors contributing to pattern and degree of tooth wear in mammals.

Dietary diversity and evolution of the earliest flying vertebrates revealed by dental microwear texture analysis

open access: yesNature Communications, 2020
Microwear patterns on teeth can be used to infer diet as different foods leave different marks. Here, Bestwick and colleagues analyse microwear from the teeth of pterosaurs—extinct flying reptiles colloquially known as “pterodactyls”—to reconstruct their

Enamel microwear in caviomorph rodents [PDF]

open access: yesJournal of Mammalogy, 2008
We developed a new data set of enamel microwear for extant caviomorph rodents (i.e., South American hystricognaths) and inferred the diet of an extinct taxon, Neoreomys australis, from data on microwear. To evaluate frequencies of wear features (pits and scratches) in caviomorphs, we employed low-magnification microwear, which has been used ...

Microwear textures associated with experimental near-natural diets suggest that seeds and hard insect body parts cause high enamel surface complexity in small mammals

open access: yesFrontiers in Ecology and Evolution, 2022
In mammals, complex dental microwear textures (DMT) representing differently sized and shaped enamel lesions overlaying each other have traditionally been associated with the seeds and kernels in frugivorous diets, as well as with sclerotized insect ...
