Skull Ontogeny and Sexual Dimorphism
The skull ontogeny and sexual dimorphism of the plains vizcacha, Lagostomus maximus, is here described from quantitative approaches. The quantitative...
-
Dynamic evolutionary interplay between ontogenetic skull patterning and whole-head integration
The arrangement and morphology of the vertebrate skull reflect functional and ecological demands, making it a highly adaptable structure. However,...

Deviations in the Development of Captivity Walrus (Odobenus rosmarus) Skull
AbstractCurrently, many aquariums and zoos around the world keep walruses in captivity. However, the presence of tusks in walruses creates...

Sexual dimorphism in the Hungarian golden jackal population: analysing body and skull size and shape
Defining species within the Canidae family is challenging due to morphological convergence, behavioral plasticity, traditional taxonomic limitations,...
-
Morphological disparity and structural performance of the dromaeosaurid skull informs ecology and evolutionary history
Non-avialan theropod dinosaurs had diverse ecologies and varied skull morphologies. Previous studies of theropod cranial morphology mostly focused on...

Red Fox Skull Size Variability Along the Ural’s Meridian: Bergmann’s Rule or the Optimum Rule?
AbstractChanges in the skull size of the red fox ( Vulpes vulpes L.) along the eastern macroslope of the Ural Range from the forest-tundra to the...

Ecomorphology of toothed whales (Cetacea, Odontoceti) as revealed by 3D skull geometry
Extant odontocetes (toothed whales) exhibit differences in body size and brain mass, biosonar mode, feeding strategies, and diving and habitat...

Differentiation of skull morphology and cranial kinesis in common toads
We examined the cranial morphology and cranial kinesis of the common toads Bufo bufo and B. spinosus with micro-computed tomography and geometric...

Parallel Evolution of Skull Form in Three Rodent Genera Inhabiting Steep Elevational Gradients of Ethiopian Highlands
Several rodent genera radiated in Ethiopian highlands during Pleistocene, giving rise to species specialized to different elevation zones. The...

Bone mineral density loci specific to the skull portray potential pleiotropic effects on craniosynostosis
Skull bone mineral density (SK-BMD) provides a suitable trait for the discovery of key genes in bone biology, particularly to intramembranous...

Feeding-Related Skull Structures of Climbing Perch Anabas testudineus (Anabantidae)
AbstractThe feeding-related skull structures are described and occluding elements of the upper and lower regions of the buccopharyngeal cavity are...

Morphological Diversity of the Skull and Lower Jaw of Three Shrew Species (Eulipotyphla, Sorex) during Depressions and Abundance Peaks
AbstractEnvironmental conditions can influence the individual development of organisms and their morphological variability at the population level....

Restructuring of Skull Modularity Pattern in Evolution Within Myotis myotis–Myotis blythii Species Group (Vespertilionidae, Chiroptera, Mammalia)
Studies of differences in modularity and integration among the related species can provide important information on their evolution. We argue that...

Morphometric and physiological development confirm skull ossification level as a reliable indicator of age in a passerine bird, the Noisy Miner
In birds, several physiological characters have been proposed and tested as possible criteria of age. Among them, skull development is likely to...

Postweaning Skull Growth in Living American and Australasian Marsupials: Allometry and Evolution
Previous reports have shown an effect of historical legacy on patterns of growth of the mammal skull. The knowledge of developmental patterns of the...

Skull of a new periptychid mammal from the lower Paleocene Denver Formation of Colorado (Corral Bluffs, El Paso County)
The Periptychidae, an extinct group of archaic ungulates (‘condylarths’), were the most speciose eutherian mammals in the earliest Paleocene of North...

Decoupling the skull and skeleton in a Cretaceous bird with unique appendicular morphologies
The Cretaceous is a critical time interval that encompasses explosive diversifications of terrestrial vertebrates, particularly the period when the...

ANINet: a deep neural network for skull ancestry estimation
BackgroundAncestry estimation of skulls is under a wide range of applications in forensic science, anthropology, and facial reconstruction. This...

A complete skull of a stem mammal from the Late Triassic of Brazil illuminates the early evolution of prozostrodontian cynodonts
AbstractTriassic cynodonts from South America are key taxa in the investigation of the emergence of mammalian characters. One of the most iconic...

Flexible conservatism in the skull modularity of convergently evolved myrmecophagous placental mammals
BackgroundThe skull of placental mammals constitutes one of the best studied systems for phenotypic modularity. Several studies have found strong...
