Short Communication: Intra-Individual Microwear Variation: Deciduous versus Permanent Dentition

Dental Anthropology, 2010
This study compares microwear patterns on deciduous and permanent dentition within individuals. Number of features, total number of pits, mean pit breadth and mean scratch breadth are compared in 11 individuals aged 6-12 years.

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

Acta Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

The Anatomical Record, Volume 309, Issue 9, Page 2411-2423, September 2026.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

The Anatomical Record, Volume 309, Issue 9, Page 2424-2441, September 2026.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

The dental microwear texture of wild boars from Japan reflects inter- and intra-populational feeding preferences

Frontiers in Ecology and Evolution, 2022
Dental microwear texture analysis (DMTA) is rapidly expanding for the dietary estimation of extinct animals. There has been an extensive accumulation of microwear texture data from herbivorous mammals, especially for ruminant artiodactyls, but suids are ...

Dental microwear texture analysis of extant koalas: clarifying causal agents of microwear

Journal of Zoology, 2016
AbstractMicroscopic wear patterns on teeth, that is, dental microwear, are capable of recording observed dietary behaviour in a diversity of extant and extinct animals. However, recent work has questioned the utility of dental microwear at clarifying dietary behaviour, instead suggesting that dental microwear textures are reflective of grit consumed ...

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

The Anatomical Record, Volume 309, Issue 9, Page 2455-2475, September 2026.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Mechanisms of tooth damage and Paranthropus dietary reconstruction

Biosurface and Biotribology, 2018
According to the current fossil record, the extinct hominin genus Paranthropus and the genus Homo both first appeared ∼2.7 million years ago. Despite this similarity in geological age, Paranthropus evolved enormous postcanine teeth with very thick enamel

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, Volume 309, Issue 9, Page 2442-2454, September 2026.
Abstract 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. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

Contribution à l’étude des sillons subverticaux intéressant des facettes interproximales

Bulletins et Mémoires de la Société d’Anthropologie de Paris, 2002
Neanderthal dental remains were discovered in the cave at Rochelot (Charente, France) which is known to have been inhabited by hyenas. Two left teeth, PM1 and PM2, presented subvertical grooves located on their antagonist interproximal facets ...
