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.

The use of fan scrapers: Microwear evidence from Late Pottery Neolithic and Early Bronze Age, Ein Zippori, Israel

Journal of Lithic Studies, 2016
The results of a microwear analysis of samples of fan scrapers and fan scrapers spalls from late Pottery Neolithic (PN) and Early Bronze Age (EBA) occupation layers at Ein Zippori, Lower Galilee, Israel are presented.

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 ...

Microwear analysis of small recycled flakes and recycling products from the Ein-Zippori site, Lower Galilee, Israel

Journal of Lithic Studies, 2018
A microwear analysis of recycled lithic artefacts from late Pottery Neolithic Wadi Rabah and Early Bronze Age layers at Ein-Zippori, Israel included cores-on-flakes (COFs) which are discarded blanks made into cores, and the flakes detached from them ...

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 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

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.

'Durable Residues': Addressing the use of microwear, a case study from March Hill

Internet Archaeology, 2009
Different cultural and research traditions have led to distinctively different approaches to lithics analysis. An integration of different approaches can often give new 'ways of seeing' artefact assemblages and distribution patterns and provide valuable ...

The Role of Grass vs. Exogenous Abrasives in the Paleodietary Patterns of North American Ungulates

Frontiers in Ecology and Evolution, 2019
Equids have often been discussed regarding tooth morphological change due to the evolution of highly hypsodont teeth over time, the hyper-grazing habits of modern horses, and an older view that the acquisition of hypsodonty and the widespread appearance ...

Simulating taphonomic processes on teeth: The impact of sediment pressure and thermal alteration on dental microwear

Quaternary Science Advances
Dietary reconstructions based on dental microwear methodologies may be limited due to the various taphonomic processes that affect the formation of archaeological deposits. These limitations are primarily affected by two issues: 1) taphonomic alterations
