Taxonomic and Seasonal Variation Among Extant Hyracoids Based on Dental Microwear Texture Analysis
… forms of the order. Here, I analyze the dental microwear of modern hyraxes to assess dietary and ecological relationships among the four extant species of Procaviidae: <em>Heterohyrax brucei</em>, <em>Procavia capensis</em>, <em>Dendrohyrax arboreus</em>, and <em>Dendrohyrax dorsalis</em>. The …

Canine dental microwear and light stable isotopic analyses of some South African holocene populations
… which to evaluate the efficacy of canine dental microwear in distinguishing different diets between some Holocene populations in southern Africa. It has been recognised for some time that the use of stable isotopes as the basis for dental microwear evaluations may be a valuable method for …

Effects of Instrumentation on Dental Microwear Textures: Reanalysis and Augmentation of an Early Hominin Sample
<p>Dental microwear texture analysis has been refined to a methodology relying upon scanning confocal microscopy for its advantages of repeatability and standardized quantification. A new instrument, the Plu Neox (Sensofar Corp.) confocal profiler recently entered the market, sparking questions …

Analysis of Bone Crushing Behavior of the Dire Wolf (<em>Canis dirus</em>) Using Dental Microwear Texture Analysis.
… gray wolf (<em>C. lupus</em>). Here dental microwear texture analysis of the m2 is used to test the hypothesized dietary behavior of <em>C. dirus</em>. If the m2 does distinguish dietary tendencies and dire wolves were heavy bone consumers, then the microwear signals of <em>C. dirus</em> …

Dental Microwear Textures of Paranthropus robustus from Kromdraai, Drimolen, and an Enlarged Sample from Swartkrans: Ecological and Intraspecific Variation
<p>The original microwear texture baseline for South African hominins was done by Scott et al. (2005) and concluded that Paranthropus robustus exhibited higher complexity values (Asfc) that are seen in occasional hard object feeders. Australopithecus africanus has higher anisotropy values (epLsar) …

Diet Assessment in Tropical African Populations - the implications of detecting biological signals in current diets to the study of past diets
… in the past, stable isotope ratio and dental microwear analyses are often perceived as the only semi-quantitative and objective techniques. However, there are still many unknowns on how isotopic and microwear signals change in response to dietary variation, because few controlled studies have …

Diet and Behavior of Ancient Maya: Using Dental Wear Patterns
… enamel features associated with molar macro and microwear can provide evidence of the type (hard, tough, or soft) and quantity of food, and food processing. This study assessed macro- and microwear of maxillary and mandibular first, second and third molars from royals (n=7), sub-royals (n=9), and …

Evolution of the diets of Australian Possums (Marsupialia: Phalangeriformes) from the Etadunna Formation in the Lake Eyre Basin, South Australia
… Kendall’s ranked correlation. Additionally, a microwear analysis can help further narrow down possible dietary niches. Microwear refers to the microscopic pits and grooves in teeth created by food substrate grinding against the teeth during chewing. The ratio of scratches to pits is determined …

Variation and the evolutionary drivers of diversity in the genus Paranthropus
… Recent research on craniodental morphology, microwear, biomechanics, and isotopes, by contrast, has suggested that substantial variation exists within the genus Paranthropus, both in terms of ecological niches occupied by the three recognized species within the genus and the amount of …

Dietary ecology of mixed-feeding antelopes in the Omo-Turkana basin during the Plio-Pleistocene: a tool to investigate hominin palaeo-environments.
… carbon and oxygen isotope, mesowear and dental microwear textural analyses. To provide more tools to interpret fossil evidence, predictive models were tested to study the relationship between land cover and dietary behaviours of modern populations. The high variability of stable carbon isotope …

Pigs from six medieval sites in Flanders: A multiple methodological approach to the study of their husbandry development
… utilised in this project include dental microwear, linear enamel hypoplasia, and identification of pathologies or anomalies in both teeth and post-cranial elements, set alongside more traditional examinations of both mandibular and post-cranial elements. This provided an in-depth …

Le faune del Paleolitico medio-superiore in Nord Italia: nuovi dati archeozoologici dal Riparo Mochi e dal Riparo Tagliente
… applied here range from analyses of dental microwear to the use of 3D technology for the study of bone artifacts. The archaeozoological analysis of these two contexts is also necessary due to the scarcity of faunal data for the two sites, which are infact preliminary or incomplete. How did …

Using a multiproxy analysis of springbok fossils to track 2 million years of vegetation changes experienced by hominins in southern Africa.
… the lifetime (mesowear) and end of life (microwear) dietary signals, supplemented by the early years signal from stable isotope analysis (carbon and oxygen). Further palaeoenvironmental conditions, such as precipitation levels (oxygen isotopes) and exogenous grit/dust particles (use-wear) …

Functional Analysis of Polished-edge Discoidal Knives of the British Isles
Polished-edge discoidal knives are part of the lithic material culture from the British Isles with an approximate Late Neolithic date. These artefacts are manufactured in three basic shapes: circular to D-shaped, triangular, and broad leaf to lozenge (Clark 1929). The aim of this project was to …
