Microanatomical diversity of the humerus and lifestyle in lissamphibians
A study of body size and the compactness profile parameters of the humerus of 37 species of lissamphibians demonstrates a relationship between lifestyle (aquatic, amphibious or terrestrial) and boneExpand

Bone Microstructure of the Stereospondyl Lydekkerina Huxleyi Reveals Adaptive Strategies to the Harsh Post Permian‐Extinction Environment
The small‐bodied stereospondyl Lydekkerina huxleyi, dominated the amphibian fauna of the South African Lower Triassic. Even though the anatomy of this amphibian has been well described, its growthExpand

New Insights into the Biology of the Permian Genus Cistecephalus (Therapsida, Dicynodontia)
ABSTRACT The taxonomy and paleobiology of the Upper Permian dicynodont Cistecephalus have been much debated over the last century. Fossils of Cistecephalus have been identified as belonging eitherExpand

Early genome size increase in urodeles
Abstract Urodeles have the largest genomes among extant tetrapods, varying greatly between metamorphic and neotenic species, which have the smallest and the largest genomes of the group,Expand

Use of paleontological and molecular data in supertrees for comparative studies: the example of lissamphibian femoral microanatomy
A new method to assemble time‐calibrated supertrees is able to incorporate paleontological and molecular dates. This method, along with new branch length transformations, is implemented in theExpand

Diminutive fleet-footed tyrannosauroid narrows the 70-million-year gap in the North American fossil record
To date, eco-evolutionary dynamics in the ascent of tyrannosauroids to top predator roles have been obscured by a 70-million-year gap in the North American (NA) record. Here we report discovery ofExpand

Macroevolution of genome size in sarcopterygians during the water–land transition
Abstract Genome size spans over a 300-fold range among vertebrates (132 pg for Protopterus aethiopicus, the marbled lungfish, and 0.35 pg for Tetraodon nigroviridis, the green spotted pufferfish).Expand

Bone Microstructure of Pareiasaurs (Parareptilia) from the Karoo Basin, South Africa: Implications for Growth Strategies and Lifestyle Habits
Numerous morphological studies have been carried out on pareiasaurs; yet their taxonomy and biology remain incompletely understood. Earlier works have suggested that these herbivorous parareptilesExpand

Insights into the habitat of Middle Permian pareiasaurs (Parareptilia) from preliminary isotopic analyses
Pareiasaurs were an abundant group of large herbivores during Middle and Late Permian times. The habitat of pareiasaurs has proven enigmatic, and ecological interpretations from anatomical andExpand

Oxygen isotope fractionation between bird bone phosphate and drinking water
Oxygen isotope compositions of bone phosphate (δ18Op) were measured in broiler chickens reared in 21 farms worldwide characterized by contrasted latitudes and local climates. These sedentary birdsExpand
