Within‐guild dietary discrimination from 3‐Dtextural analysis of tooth microwear in insectivorous mammals [PDF]
Journal of Zoology, 2013 AbstractResource exploitation and competition for food are important selective pressures in animal evolution. A number of recent investigations have focused on linkages between diversification, trophic morphology and diet in bats, partly because their roosting habits mean that for many bat species diet can be quantified relatively easily through faecal

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications. [PDF]
Anat Rec (Hoboken)Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Reconstruction of feeding behaviour and diet in Devonian ctenacanth chondrichthyans using dental microwear texture and finite element analyses [PDF]
Royal Society Open ScienceDevonian ctenacanth chondrichthyans reached body sizes similar to modern great white sharks and therefore might have been apex predators of the Devonian seas.

Neandertal predation agenda reveals seasonal strategies during MIS 5–4 transition in Axlor, northatlantic Iberia [PDF]
Scientific ReportsAs hunter-gatherers, neandertal groups were mobile, moving within their territory based on the availability of targeted resources. Their mobility was an integral part of their subsistence strategies.

Tooth microwear formation rate in Gasterosteus aculeatus. [PDF]
J Fish Biol, 2014 Tooth microwear feature densities were significantly increased in a population of laboratory‐reared three‐spined stickleback Gasterosteus aculeatus in four days, after they were transferred from a limnetic feeding regime to a benthic feeding regime. These results show that even in aquatic vertebrates with non‐occluding teeth, changes in feeding can ...

Lifestyle changes and its effect towards the evolution of human dentition
Egyptian Journal of Forensic Sciences, 2022 Background The dentition of modern humans has evolved from their hominid ancestors to their current form. Factors regarding the changes of lifestyle such as dietary habits and usage of tools have affected the evolution of human dentition.

Royal Society Open Science, 2022 Dental microwear is used to investigate feeding ecology. Animals ingest geological material in addition to food. The full effect of geological abrasives on tooth wear is unknown.

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 ...

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 ...

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.
