Bovid astragali are one of the most commonly preserved bones in the fossil record. [...] Key Method A diverse sample of 181 astragali from 50 extant species was scanned using a Next Engine laser scanner. Species were assigned to one of four habitat categories based on the published ecological literature. A series of 11 linear measurements and three joint surface areas were measured on each astragalus. A geometric mean body size proxy was used to size-correct the measurement data.Expand
Assessing astragalar morphology and biomechanics in western Palaearctic Bison populations with geometric morphometrics
TLDR
A framework of ecomorphological differences among several Bison populations of the western Palaearctic is outlined, shown by inferences from the tibial and tarsal joint surfaces of their astragalus, to indicate a biogeographic segregation influenced by regional climatic and landscape heterogeneity in the European territory during Pleistocene.

The Morphology of the Bovid Calcaneus: Function, Phylogenetic Signal, and Allometric Scaling
Despite its clear functional role in hock (ankle) plantarflexion, the bovid calcaneus has been understudied with respect to the functional constraints imposed by locomotion in differing habitats, theExpand
The Morphology of the Bovid Calcaneus: Function, Phylogenetic Signal, and Allometric Scaling
TLDR
Overall, the morphology of the bovid calcaneus has been shaped by a complex interaction of phylogenetic and body-size constraints as well as adaptation to modes of predator avoidance mediated by preferred habitat. Expand
Astragalar Morphology of Selected Giraffidae
The artiodactyl astragalus has been modified to exhibit two trochleae, creating a double pullied structure allowing for significant dorso-plantar motion, and limited mediolateral motion. TheExpand

Ecomorphology and ecology of the grassland specialist, Rusingoryx atopocranion (Artiodactyla: Bovidae), from the late Pleistocene of western Kenya
Abstract Rusingoryx atopocranion is an extinct alcelaphin bovid from the late Pleistocene of Kenya, known for its distinctive hollow nasal crest. A bonebed of R. atopocranion from the Lake VictoriaExpand
Using Astragalus to Model Body Mass, Habitat Preference, and Population Density of Prehistoric Bovid Duboisia santeng (Dubois, 1891) in Eastern Java island in The Early Pleistocene
Astragalus bone is one of the most important fossil records as it can reconstruct the prehistoric life. Respectively, this study aims to model the body mass, habitat preference, and populationExpand
Effect of mass and habitat on the shape of limb long bones: A morpho‐functional investigation on Bovidae (Mammalia: Cetartiodactyla)
TLDR
This work presents the first 3D geometric morphometric study focusing on bovid limb long bones, using anatomical landmarks as well as curve and surface sliding semi‐landmarks to accurately describe the stylopod and zeugopod bones. Expand
Exploring morphological generality in the Old World monkey postcranium using an ecomorphological framework
TLDR
Analysis of the associations between habitat, locomotion and morphology in the forelimbs of cercopithecids (Old World monkeys) is explored, contextualising their skeletal ecomorphological patterns with those of other mammals, and complementing functional morphological analyses with phylogenetic comparative techniques. Expand
Influence of mass on tarsus shape variation: a morphometrical investigation among Rhinocerotidae (Mammalia: Perissodactyla)
TLDR
The results show that mass has an influence on bone shape in Rhinocerotidae and in Perissodactyla, but this is not as strong as expected. Expand

Habitat preference of extant African bovids based on astragalus morphology: operationalizing ecomorphology for palaeoenvironmental reconstruction
TLDR
A discriminant function model linking astragalus morphology to four broadly defined habitat categories (open, light cover, heavy cover, and closed) using modern bovids of known ecology is presented. Expand
Ecomorphology and phylogenetic risk: Implications for habitat reconstruction using fossil bovids.
TLDR
It is suggested that the way forward for ecomorphology is grounded in functionally relevant observations and careful consideration of phylogeny designed to bracket probable habitat preferences appropriately, and separate consideration of different morphological variables may help to determine the level of 'phylogenetic risk' attached to conclusions linking habitat and morphology. Expand
A method for inferring paleohabitats from the functional morphology of bovid astragali
TLDR
This work describes here a method for predicting paleohabitats using measurements of bovid astragali, and demonstrates that the habitat predictions are generally robust, and are relatively independent of body weight, taxonomy, and sample composition. Expand
Morphology and locomotor adaptations of the bovid femur in relation to habitat
TLDR
An investigation of the linkage between these locomotor patterns and habitat based on a study of the morphology of the bovid femur finds a statistically significant separation of the different morphological complexes present in bovids from forest, broken cover, and savanna habitats. Expand
The paleoenvironment ofKenyapithecus at Fort Ternan
TLDR
A study of the morphology of the bovid hind limb that demonstrates a functional linkage between several femoral characters and habitat type as these features relate to locomotion and provides a sound basis for interpreting the locomotor adaptations of fossil bovids. Expand
Bovids as indicators of Plio-Pleistocene paleoenvironments in east Africa.
TLDR
This study addresses the functional morphology of the bovid femur through discriminant function analysis and provides additional support for the observation that certain features of the femur demonstrate clear correlations with the amount of vegetative cover in different modern habitats. Expand
Morphometric identification of bovid metapodials to genus and implications for taxon-free habitat reconstruction
TLDR
Principal Components Analysis (PCA) of measurements indicates that metapodials differ much more in size than in shape among the twenty-three genera of extant Sub-Saharan bovids, and shows that bovid species that favor the same habitat often differ in meetingapodial size, shape, or both, and species that Favor different habitats often overlap substantially in their metapidial morphometrics.

Bovid postcranial ecomorphological survey of the Laetoli paleoenvironment.
TLDR
A bovid postcranial ecomorphological survey of the fossil assemblages from the Plio-Pleistocene site of Laetoli, Tanzania indicates that, at the time of the deposition of the Laetolil Beds, the area had heavy woodland-bushland cover with some lighter tree and bush cover and grass available. Expand
