Dental wear and oral pathology among sex determined Early Bronze-Age children from Franzhausen I, Lower Austria.

PLoS ONE, 2023
The physical properties of diet and oral health throughout childhood play an important role in the development of human dentition, and differed greatly before the industrial revolution. In this study we examined dental wear and oral pathology in a sample

DIETARY TRAITS OF LATE MIOCENE HIPPARIONS FROM MARAGHEH REVEALED THROUGH DENTAL WEAR

Rivista Italiana di Paleontologia e Stratigrafia, 2023
This study investigates the palaeoecology of fossil perissodactyls (equids) from the late Miocene of Maragheh, northwestern Iran. We used dental micro- and mesowear techniques to draw robust inferences about fossil equid paleoenvironment.

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.

Caprine dental microwear reveals livestock management and exploitation of landscape during the Middle and Late Bronze Age of the Balearic Islands (ca. 1500–850 cal. BC)

Archaeological and Anthropological Sciences, 2022
In the last few decades, bioarchaeological studies have grown exponentially on the Balearic Islands. In general, animal husbandry based on domestic triad and a Mediterranean macchia landscape is well-attested during the prehistory of this archipelago ...

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

The Anatomical Record, EarlyView.
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.

Microwear textures associated with experimental near-natural diets suggest that seeds and hard insect body parts cause high enamel surface complexity in small mammals

Frontiers in Ecology and Evolution, 2022
In mammals, complex dental microwear textures (DMT) representing differently sized and shaped enamel lesions overlaying each other have traditionally been associated with the seeds and kernels in frugivorous diets, as well as with sclerotized insect ...

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

The Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Kaelin Rapport - Histological Techniques for the Sex Determination of Skeletonized Human Remains [PDF]

, 2014
Determining the sex of skeletons is problematic in forensic and bio-archaeological research. Past studies demonstrate that bone cells can sometimes contain preserved sex chromosomal material in ancient samples. The sex chromosomes in skeletal remains may

Inter-microscope comparability of dental microwear texture data obtained from different optical profilometers

bioRxiv, 2022
Dental microwear texture analysis has become a well-established approach for dietary inference and reconstruction of mammals and other tetrapods, both extant and extinct.
