An eye for a tooth: Thylacosmilus was not a marsupial “saber-tooth predator” [PDF]
PeerJ, 2020 Background Saber-toothed mammals, now all extinct, were cats or “cat-like” forms with enlarged, blade-like upper canines, proposed as specialists in taking large prey.

Behavioral strategies of prehistoric and historic children from dental microwear texture analysis
Frontiers in Ecology and Evolution, 2022 IntroductionReconstructing the dietary and behavioral strategies of our hominin ancestors is crucial to understanding their evolution, adaptation, and overall way of life.

Dental topography and microwear texture in Sapajus apella
Biosurface and Biotribology, 2017 Dental microwear texture pattern has been associated with aspects of diet for a broad range of mammalian taxa. The basic idea is that soft, tough foods are sheared with a steeper angle of approach between opposing occlusal surfaces, whereas hard, brittle

Frontiers 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 ...

Dental microwear texture analysis as a tool for dietary discrimination in elasmobranchs
Scientific Reports, 2021 As abundant and widespread predators, elasmobranchs play influential roles in food-web dynamics of marine communities. Clearly, these trophic interactions have significant implications for fisheries management and marine conservation, yet elasmobranch ...

Dental microwear texture analysis on extant and extinct sharks: Ante- or post-mortem tooth wear?
Palaeogeography, Palaeoclimatology, Palaeoecology, 2021 Abstract Sharks are apex-predators that play an important role in past and present aquatic food webs. However, their diet - especially in extinct species - is often not well constrained. Dental microwear texture analysis (DMTA) has been successfully applied to reconstruct diet and feeding behaviours of different aquatic and terrestrial vertebrates ...

3D tooth microwear texture analysis in fishes as a test of dietary hypotheses of durophagy [PDF]
Surface Topography: Metrology and Properties, 2015 An understanding of how extinct animals functioned underpins our understanding of past evolutionary events, including adaptive radiations, and the role of functional innovation and adaptation as drivers of both micro- and macroevolution. Yet analysis of function in extinct animals is fraught with difficulty.

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.

PLoS ONE, 2014 Megaherbivorous dinosaurs were exceptionally diverse on the Late Cretaceous island continent of Laramidia, and a growing body of evidence suggests that this diversity was facilitated by dietary niche partitioning. We test this hypothesis using the fossil
