Wearing down the constraints of low magnification tooth microwear analysis: reproducibility and variability of results based on extant ungulates [PDF]

Palaontologische Zeitschrift, 2021
AbstractLow magnification dental microwear analysis is a widespread dietary proxy for palaeoenvironmental analyses. The limitations of the method, such as observer bias or variation of microwear scars between different tooth positions, are still not quite understood.

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 diet in the African Viverridae

Canadian Journal of Zoology, 1987
Distinct tooth microwear patterns were observed in viverrids (Carnivora). Epoxy replicas of the upper tooth row of 32 specimens of 12 species of African viverrids were prepared and examined using a scanning electron microscope. Four general patterns emerged: (i) teeth with deeply scored grooves and scratches predominantly in the vertical direction ...

Tooth microwear pattern variation in karst and non-karst peninsular Southeast Asian murine rodents

Mammal Research, 2023
International audience ; The dietary preferences of most rodents, especially in tropical countries, are poorly known. In the tropics, rodent diversity can be high and several species can coexist in the same habitats. In order to better document the dietary habits of Southeast Asian murid and diatomyid rodents, we examined microwear patterns in 21 ...

Tooth microwear and premaxillary shape of an archaic antelope

Lethaia, 1993
Extant ungulates can be divided into three dietary categories: browsing feeders, grazing feeders, and mixed feeders. Dietary adaptations can be differentiated in extinct ruminants based upon tooth microwear analysis as well as evaluation of premaxillary morphology.

Dental microwear of European Miocene catarrhines: evidence for diets and tooth use

Journal of Human Evolution, 1996
Abstract Paleontologists have identified ape-like primates from the middle and late Miocene of Europe for more than a century, and new finds continue to improve the record of these important forms. Both hominoids and plio-pithecids are recognized in these assemblages.

Dietary plasticity in ungulates: Insight from tooth microwear analysis

Quaternary International, 2011
Abstract In recent years, tooth microwear has been used as a powerful tool for investigating mammalian diets in paleontological or archaeological contexts. Tooth microwear techniques were applied to a number of late Pleistocene assemblages of bison (Bison antiquus) from North America to analyze bison dietary traits, but more particularly, to test for

First insights into the function of the sawshark rostrum through examination of rostral tooth microwear

Journal of Fish Biology, 2017
Potential roles of the rostrum of sawsharks (Pristiophoridae), including predation and self‐defence, were assessed through a variety of inferential methods. Comparison of microwear on the surface of the rostral teeth of sawsharks and sawfishes (Pristidae) show that microwear patterns are alike and suggest that the elongate rostra in these two ...
