Trophic evolution in ornithopod dinosaurs revealed by dental wear [PDF]

open access: yesNature Communications
Ornithopod dinosaurs evolved numerous craniodental innovations related to herbivory. Nonetheless, the relationship between occlusion, tooth wear rate, and tooth replacement rate has been neglected. Here, we reconstruct tooth wear rates by measuring tooth

The primate community of Cachoeira (Brazilian Amazonia): a model to decipher ecological partitioning among extinct species. [PDF]

open access: yesPLoS ONE, 2011
Dental microwear analysis is conducted on a community of platyrrhine primates from South America. This analysis focuses on the primate community of Cachoeira Porteira (Para, Brazil), in which seven sympatric species occur: Alouatta seniculus, Ateles ...

Controlled feeding experiments with juvenile alligators reveal microscopic dental wear texture patterns associated with hard-object feeding

open access: yesFrontiers in Ecology and Evolution, 2022
Dental wear analyses are classically applied to mammals because they have evolved heterodont dentitions for sophisticated mastication. Recently, several studies have shown a correlation between pre-assigned and analytically inferred diet preferences in ...

Dietary abrasiveness is associated with variability of microwear and dental surface texture in rabbits. [PDF]

open access: yesPLoS ONE, 2013
Dental microwear and 3D surface texture analyses are useful in reconstructing herbivore diets, with scratches usually interpreted as indicators of grass dominated diets and pits as indicators of browse.

Comparing maxillary first molar crown shape using elliptical Fourier analysis in the Late Neolithic cave burials of Belgium

open access: yesAnthropological Review, 2021
The Belgian Meuse karstic basin holds more than 200 Late Neolithic collective burials. Four of the largest include Hastière Caverne M, Hastière Trou Garçon C, Sclaigneaux and Bois Madame.

Accuracy of dental microwear impressions by physical properties of silicone materials

open access: yesFrontiers in Ecology and Evolution, 2022
Dental microwear analysis is an oft-used paleodietary estimation method, and the impression molds or resin casts are often analyzed rather than the original tooth surfaces.

Dental microwear differences between eastern and southern African fossil bovids and hominins

open access: yesSouth African Journal of Science, 2016
Dental microwear has proven to be a valuable tool for reconstructing diets of fossil vertebrates. However, recent studies have suggested that the pattern of microscopic scratches and pits on teeth may be more reflective of environmental grit than of food

Post-mortem enamel surface texture alteration during taphonomic processes—do experimental approaches reflect natural phenomena? [PDF]

open access: yesPeerJ, 2022
Experimental approaches are often used to better understand the mechanisms behind and consequences of post-mortem alteration on proxies for diet reconstruction.

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.
