PLoS ONE, 2017 Analyses of dental micro- and macro-wear offer valuable information about dietary adaptations. The buccal surface of the teeth does not undergo attrition, indicating that dental microwear may directly inform about food properties. Only a few studies have,

The Anatomical Record, EarlyView.Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Short Communication: Intra-Individual Microwear Variation: Deciduous versus Permanent Dentition
Dental Anthropology, 2010 This study compares microwear patterns on deciduous and permanent dentition within individuals. Number of features, total number of pits, mean pit breadth and mean scratch breadth are compared in 11 individuals aged 6-12 years.

The Anatomical Record, EarlyView.Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

The Anatomical Record, EarlyView.Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

Dental microwear texture analysis of extant koalas: clarifying causal agents of microwear
Journal of Zoology, 2016 AbstractMicroscopic wear patterns on teeth, that is, dental microwear, are capable of recording observed dietary behaviour in a diversity of extant and extinct animals. However, recent work has questioned the utility of dental microwear at clarifying dietary behaviour, instead suggesting that dental microwear textures are reflective of grit consumed ...

A Modern Metrical Baseline for Sexing Sheep Horn‐Cores
International Journal of Osteoarchaeology, EarlyView.ABSTRACT Sex determination is essential for reconstructing past livestock management, yet the limited skeletal sexual dimorphism of sheep hinders the identification of ewes, rams, and wethers in archaeological assemblages. Horn‐cores are the most sexually dimorphic element of the sheep skeleton, and here, we establish a new metrical baseline for ...

steel research international, EarlyView.Niobium cathodic cage duplex treatment is applied to VP20TS steel to evaluate the influence of surface roughness and temperature on coating performance. Results show that higher temperatures promote thicker nitride layers and increased microhardness, while finer surface preparation enhances adhesion and wear resistance, revealing optimal conditions for

Mechanisms of tooth damage and Paranthropus dietary reconstruction
Biosurface and Biotribology, 2018 According to the current fossil record, the extinct hominin genus Paranthropus and the genus Homo both first appeared ∼2.7 million years ago. Despite this similarity in geological age, Paranthropus evolved enormous postcanine teeth with very thick enamel

Frontiers in Ecology and Evolution, 2022 Dental microwear texture analysis (DMTA) is rapidly expanding for the dietary estimation of extinct animals. There has been an extensive accumulation of microwear texture data from herbivorous mammals, especially for ruminant artiodactyls, but suids are ...
