Effects of Instrumentation on Dental Microwear Textures: Reanalysis and Augmentation of an Early Hominin Sample [PDF]

, 2014
Dental microwear texture analysis has been refined to a methodology relying upon scanning confocal microscopy for its advantages of repeatability and standardized quantification.

What can lithics tell us about food production during the transition to farming? Exploring harvesting practices and cultural changes during the neolithic in Southwest Asia: a view from Qminas (north‐western Syria)

Archaeometry, EarlyView.
Abstract This study examines the continuity and change in harvesting practices between the Late Pre‐Pottery Neolithic B (LPPNB) and the Early Pottery Neolithic at Qminas, north‐western Levant, through a traceological analysis of flint sickles. By combining qualitative traceological analysis with quantitative functional approaches, we demonstrate that ...

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 ...

Comparison of Microwear on Rodent Molars from Differing Species and a Wide Range of Environments [PDF]

, 2015
Dental microwear analysis is a very useful tool when trying to infer the diet of a particular organism. By studying the use-wear scars left on the enamel of the tooth due to eaten objects, one can infer the diet of the organism because certain types of ...

Tooth microwear formation rate in Gasterosteus aculeatus

Journal of Fish Biology, 2014
Tooth microwear feature densities were significantly increased in a population of laboratory‐reared three‐spined stickleback Gasterosteus aculeatus in four days, after they were transferred from a limnetic feeding regime to a benthic feeding regime. These results show that even in aquatic vertebrates with non‐occluding teeth, changes in feeding can ...

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.

Fracture in teeth—a diagnostic for inferring bite force and tooth function [PDF]

, 2011
Teeth are brittle and highly susceptible to cracking. We propose that observations of such cracking can be used as a diagnostic tool for predicting bite force and inferring tooth function in living and fossil mammals.

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

Boreas, EarlyView.
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 Properties of Plant Underground Storage Organs and Implications for Dietary Models of Early Hominins [PDF]

, 2008
The diet of early human ancestors has received renewed theoretical interest since the discovery of elevated d13C values in the enamel of Australopithecus africanus and Paranthropus robustus.
