Tooth Function of the Northern Raccoon (Procyon lotor) and Adaptations to Omnivory in the Order Carnivora

Journal of Morphology, Volume 287, Issue 7, July 2026.
The masticatory cycle of Procyon lotor was analysed and visualised, elucidating the occlusal relationships of its cheek dentition. Grinding and crushing were found to play a major role in the tooth function of P. lotor. An OFA analysis furthermore revealed an occlusal relationship between the M1 metaconule and the trigonid basin of the m2, indicating ...

Dental microwear texture analysis of extant koalas: clarifying causal agents of microwear

Journal of Zoology, 2016
AbstractMicroscopic wear patterns on teeth, that is, dental microwear, are capable of recording observed dietary behaviour in a diversity of extant and extinct animals. However, recent work has questioned the utility of dental microwear at clarifying dietary behaviour, instead suggesting that dental microwear textures are reflective of grit consumed ...

THE DIET OF WORMS: AN ANALYSIS OF MOLE DENTAL MICROWEAR [PDF]

Journal of Mammalogy, 2002
We compared microwear from shearing facets of lower molars from Parascalops breweri (the hairy-tailed mole) and Scapanus orarius (the coast mole) with that from other small mammal species including a tenrec, a hedgehog, 3 primates, and 2 bats. The 2 mole species exhibit a distinct microwear pattern that is characterized by many short, narrow scratches,

Fossil bears break free from inhibitory cascade constraints at least twice (Ursus minimus and Ursus deningeri) caused by dietary adaptations

Boreas, Volume 55, Issue 2, Page 503-516, April 2026.
Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.

Mechanical evidence that Australopithecus sediba was limited in its ability to eat hard foods

Nature Communications, 2016
Dietary adaptations of extinct early humans are often inferred from dental microwear data. Here, the authors employ mechanical analyses to show that Australopithecus sedibahad limited ability to consume hard foods.

Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

Journal of Anatomy, Volume 247, Issue 6, Page 1109-1130, December 2025.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

A methodological approach to infer the diet: the case of the children from Cova de la Guineu (Font-Rubí, Barcelona, Spain)

UISPP Journal, 2019
Dental microwear is a widely used technique to infer the diet of ancient populations. This method allows to determine not only the physical properties of the food, such as abrasiveness or hardness, but also informs about how food was processed before ...

Myological and osteological approaches to gape and bite force reconstruction in Smilodon fatalis

The Anatomical Record, Volume 308, Issue 11, Page 2944-2961, November 2025.
Abstract Masticatory gape and bite force are important behavioral and ecological variables. While much has been written about the highly derived masticatory anatomy of Smilodon fatalis, there remains a great deal of debate about their masticatory behaviors.

Regional Differences of Dental Microwear on the Occlusal Surface of an M2 from Neolithic Japan: A Case Study

Dental Anthropology, 2005
Regional differences of dental microwear among four small areas on the heavily worn occlusal surface of a mandibular M2 of an adult male from Neolithic Japan were investigated using a scanning electron microscope (SEM).

The functional and palaeoecological implications of tooth morphology and wear for the megaherbivorous dinosaurs from the Dinosaur Park Formation (upper Campanian) of Alberta, Canada.

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
