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.

Impacted Bones: Can Extant Primates Help Identify Tool Use in Early Hominins?
Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 3, September 2026.ABSTRACT Despite recent advances pushing back the earliest record of tool use, how and when it first emerged in hominins, and the extent to which it featured amongst the numerous co‐existing species, remain critical questions in paleoanthropology. In addition to analyzing fossils and lithic toolkits, novel strides in understanding this might be made by

Dietary Adaptation in Paranthropus robustus Postcanine Teeth
American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.Upper premolar enamel thickness in Paranthropus robustus increased significantly over time, especially in the occlusal region. ABSTRACT Objectives Recent studies of Paranthropus robustus crania identified temporal trends in features associated with increased bite force production, coinciding with environmental shifts toward more arid conditions.

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 ...

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 ...

Testing the Dry Refuge Model: Paleoecological Insights From Late Pleistocene Gomphotheres in Ecuador
Ecology and Evolution, Volume 16, Issue 8, August 2026.We present paleontological evidence that may prove the Dry Refuge Model in Ecuador during the Late Pleistocene. ABSTRACT Paleoenvironmental records indicate that Neotropical regions near the Equator experienced reduced rainfall during the Last Glacial Maximum (LGM). However, some records show conflicting environmental signals.

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 ...

Journal of Morphology, Volume 287, Issue 8, August 2026.We investigated the masticatory movements of two of the three main cranial‐mandibular morphological groups in Rodents (two species each) using 3D X‐ray reconstruction. We found that both groups use different movements and modulate their chewing differently in response to different food items.
