Torsional resistance as a principal component of the structural design of long bones: comparative multivariate evidence in birds.
Here we study the occurrence of torsion-resisting morphological and histological features (thin bone walls, circular shaft cross-section, oblique collagen fibers, and laminar tissue arrangement) in aExpand

The evolutionary radiation of Arvicolinae rodents (voles and lemmings): relative contribution of nuclear and mitochondrial DNA phylogenies
BackgroundMitochondrial and nuclear genes have generally been employed for different purposes in molecular systematics, the former to resolve relationships within recently evolved groups and theExpand

A primitive placoderm sheds light on the origin of the jawed vertebrate face
Extant vertebrates form two clades, the jawless Cyclostomata (lampreys and hagfishes) and the jawed Gnathostomata (all other vertebrates), with contrasting facial architectures. These arise duringExpand

Limb‐bone histology of temnospondyls: implications for understanding the diversification of palaeoecologies and patterns of locomotion of Permo‐Triassic tetrapods
The locomotion of early tetrapods has long been a subject of great interest in the evolutionary history of vertebrates. However, we still do not have a precise understanding of the evolutionaryExpand

Molecular and morphological phylogenies of the Antarctic teleostean family Nototheniidae, with emphasis on the Trematominae
Four independent molecular data sets were sequenced in order to solve longstanding phylogenetic problems among Antarctic teleosts of the family Nototheniidae. The anatomical data of Balushkin (2000)Expand

Developmental plasticity of limb bone microstructural organization in Apateon: histological evidence of paedomorphic conditions in branchiosaurs
SUMMARY Apateon, a key genus among Branchiosauridae from the Carboniferous—Permian of Europe, is often considered closely related to salamanders on the basis of developmental similarities, anatomicalExpand

The stem osteichthyan Andreolepis and the origin of tooth replacement
The teeth of gnathostomes (jawed vertebrates) show rigidly patterned, unidirectional replacement that may or may not be associated with a shedding mechanism. These mechanisms, which are critical forExpand

Three-Dimensional Synchrotron Virtual Paleohistology: A New Insight into the World of Fossil Bone Microstructures
Abstract The recent developments of phase-contrast synchrotron imaging techniques have been of great interest for paleontologists, providing three-dimensional (3D) tomographic images of anatomicalExpand

3D Microstructural Architecture of Muscle Attachments in Extant and Fossil Vertebrates Revealed by Synchrotron Microtomography
Background Firm attachments binding muscles to skeleton are crucial mechanical components of the vertebrate body. These attachments (entheses) are complex three-dimensional structures, containingExpand

Three‐dimensional virtual histology of silurian osteostracan scales revealed by synchrotron radiation microtomography
We used propagation phase contrast X‐ray synchrotron microtomography to study the three‐dimensional (3D) histology of scales of two osteostracans, Tremataspis and Oeselaspis, members of a jawlessExpand
