Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

The Anatomical Record, Volume 309, Issue 7, Page 1713-1748, July 2026.
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.

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 ...

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 ...

A Modern Metrical Baseline for Sexing Sheep Horn‐Cores

International Journal of Osteoarchaeology, Volume 36, Issue 4, Page 925-934, July/August 2026.
ABSTRACT Sex determination is essential for reconstructing past livestock management, yet the limited skeletal sexual dimorphism of sheep hinders the identification of ewes, rams, and wethers in archaeological assemblages. Horn‐cores are the most sexually dimorphic element of the sheep skeleton, and here, we establish a new metrical baseline for ...

The Paleoenvironment of the Ndutu Bed at Olduvai Gorge in the Context of Middle Stone Age Expansion in Eastern Africa: A Multiproxy Approach to Ungulate Analyses From the Victoria Cabrera Site and Dorothy Garrod Site (MIS 5)

International Journal of Osteoarchaeology, Volume 36, Issue 4, Page 1100-1113, July/August 2026.
ABSTRACT The study of the Eastern African archaeological record is essential for understanding the origin and evolution of the Middle Stone Age (MSA). However, Olduvai Gorge, one of the primary regions in human evolution studies, has few sites associated with the MSA.

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.

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.

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 ...

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
