Dental microwear texture analysis of extant sika deer with considerations on inter-microscope variability and surface preparation protocols

Biosurface and Biotribology, 2017
Recently, dental microwear texture analysis (DMTA) has been applied to various kinds of vertebrates to infer dietary preference. More data are needed on inter-microscope variability to assure the objectivity and repeatability of this method.

Dynamics of dental evolution in ornithopod dinosaurs. [PDF]

, 2016
Ornithopods were key herbivorous dinosaurs in Mesozoic terrestrial ecosystems, with a variety of tooth morphologies. Several clades, especially the 'duck-billed' hadrosaurids, became hugely diverse and abundant almost worldwide.

Dental microwear and controlled food testing on sheep: The TRIDENT project

Biosurface and Biotribology, 2017
Here, we present a short review of the most recent results that have come out of the TRIDENT project. This project aims to model tooth wear by performing controlled food testing on sheep. This approach offers us the opportunity to test various scientific

Was the giant short-faced bear a hyper-scavenger? A new approach to the dietary study of ursids using dental microwear textures.

PLoS ONE, 2013
Dramatic environmental changes associated with global cooling since the late Miocene, and the onset of glacial-interglacial cycles in the Pleistocene served as a backdrop to the evolutionary radiation of modern bears (family Ursidae). These environmental

Trace element analysis provides insight into the diets of early Late Miocene ungulates from the Rudabánya II locality (Hungary) [PDF]

, 2017
The early Late Miocene vertebrate locality of Rudabánya II (R. II) in northeastern Hungary preserves an abundance of forest-adapted ungulate species. To better understand the ecological relationships within this ancient ecosystem, we used analysis of ...

Paranthropus boisei: Fifty Years of Evidence and Analysis [PDF]

, 2007
Paranthropus boisei is a hominin taxon with a distinctive cranial and dental morphology. Its hypodigm has been recovered from sites with good stratigraphic and chronological control, and for some morphological regions, such as the mandible and the ...

Scales of analysis : evidence of fish and fish processing at Star Carr [PDF]

, 2016
This contribution directly relates to the paper published by Wheeler in 1978 entitled ‘Why were there no fish re- mains at Star Carr?’. Star Carr is arguably the richest, most studied and re-interpreted Mesolithic site in Europe but the lack of fish ...

Food habits of "Praemegaceros" cazioti (Depéret, 1897) from Dragonara Cave (NW Sardinia, Italy) inferred from cranial morphology and dental wear [PDF]

S'ha estudiat l'adaptació alimentària de "Praemegaceros" cazioti (Depéret, 1897), en base a la rica mostra trobada als dipòsits del Pleistocè tardà de la cova de Dragonara (nord-oest de Sardenya, Itàlia).

Tooth replication techniques, SEM imaging and microwear analysis in Primates: methodological obstacles

, 2004
Dental microwear analyses are among the most significant techniques though which a researcher can make dietary and ecological inferences from primate fossil specimens. Hard particles, such as plant phytoliths or silica-base sands, can scratch tooth enamel surfaces during food mastication producing a dietary specific pattern of microwear on the enamel ...
