MicroWeaR: A new R package for dental microwear analysis. [PDF]
Ecol Evol, 2018 AbstractMastication of dietary items with different mechanical properties leaves distinctive microscopic marks on the surface of tooth enamel. The inspection of such marks (dental microwear analysis) is informative about the dietary habitus in fossil as well as in modern species. Dental microwear analysis relies on the morphology, abundance, direction,

Trophic evolution in ornithopod dinosaurs revealed by dental wear [PDF]
Nature CommunicationsOrnithopod 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]
PLoS 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 ...

Frontiers 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]
PLoS 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.

Incorporating intraspecific variation into dental microwear texture analysis. [PDF]
J R Soc Interface, 2019 Dental microwear texture analysis (DMTA) quantifies microscopic scar or wear patterns left on teeth by different foods or extraneous ingested items such as grit. It can be a powerful tool for deducing the diets of extinct mammals. Here we investigate how intraspecific variation in the dental microwear of macropodids (kangaroos and their close relatives)

Accuracy of dental microwear impressions by physical properties of silicone materials
Frontiers 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.

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.

Post-mortem enamel surface texture alteration during taphonomic processes—do experimental approaches reflect natural phenomena? [PDF]
PeerJ, 2022 Experimental approaches are often used to better understand the mechanisms behind and consequences of post-mortem alteration on proxies for diet reconstruction.
