Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Evidence that metallic proxies are unsuitable for assessing the mechanics of microwear formation and a new theory of the meaning of microwear

Royal Society Open Science, 2018
Mammalian tooth wear research reveals contrasting patterns seemingly linked to diet: irregularly pitted enamel surfaces, possibly from consuming hard seeds, versus roughly aligned linearly grooved surfaces, associated with eating tough leaves. These patterns are important for assigning diet to fossils, including hominins.

Reconstructing the feeding behavior of the dwarf Sicilian hippopotamus Hippopotamus pentlandi and the implications for Hippopotamidae paleodiets

Frontiers in Ecology and Evolution
Hippopotamus pentlandi, the endemic dwarf hippopotamus of Sicily, represents one of the most iconic insular large mammals of the Mediterranean Basin. Despite the abundance of fossil remains, its feeding ecology and the environmental conditions of Sicily ...

Contribution à l’étude des sillons subverticaux intéressant des facettes interproximales

Bulletins et Mémoires de la Société d’Anthropologie de Paris, 2002
Neanderthal dental remains were discovered in the cave at Rochelot (Charente, France) which is known to have been inhabited by hyenas. Two left teeth, PM1 and PM2, presented subvertical grooves located on their antagonist interproximal facets ...

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

Acta Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

Biological Reviews, Volume 101, Issue 4, Page 1760-1778, August 2026.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

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 ...

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.

Dietary ecology of the extinct cave bear: Evidence of omnivory as inferred from dental microwear textures [PDF]

Acta Palaeontologica Polonica, 2016
The diet of the extinct European cave bear, Ursus spelaeus, has widely been debated. Diverging from the extant brown bear (Ursus arctos) approximately 1.2 million years ago, the cave bear is one of the most ubiquitous fossil bears occurring in Europe ...

Introducing ‘trident’: a graphical interface for discriminating groups using dental microwear texture analysis

Peer Community Journal
This manuscript introduces trident, an R package for performing dental microwear texture analysis and subsequently classifying variables based on their ability to separate discrete categories.
