Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

open access: yesThe Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Two-Stage Machine Learning-Based GWAS for Wool Traits in Central Anatolian Merino Sheep

open access: yesAgriculture
Wool traits such as fiber diameter, fiber length, and greasy fleece yield are economically significant characteristics in sheep breeding programs. Traditional genome-wide association studies (GWAS) have identified relevant genomic regions but often fail ...

A comparison of phenotypic performance of wool physical properties in Awassi ewes [PDF]

open access: yesIraqi Journal of Veterinary Sciences, 2014
Data from two different animal stations were recorded on two flocks of Awassi ewes. Data were analyzed for two productive seasons 2010 and 2011 years to estimate wool yield, Physical Properties and the phenotypic relationships between them.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

open access: yesThe Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Evolutionary morphology of the haplorhine hamate

open access: yesThe Anatomical Record, EarlyView.
Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

open access: yesThe Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Variation in the Exon 3–4 Region of Ovine KRT85 and Its Effect on Wool Traits

open access: yesAnimals
α-keratins are structural proteins in the cortex of wool fibres and assemble in an organized fashion into keratin intermediate filaments. Variation in these keratin proteins affects the structure and characteristics of wool fibre, making keratin genes ...

Bite force estimates and morphological correlations of jaw muscles in parrots

open access: yesThe Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

open access: yesThe Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass
