Fossils, molecules, divergence times, and the origin of lissamphibians.
A review of the paleontological literature shows that the early dates of appearance of Lissamphibia recently inferred from molecular data do not favor an origin of extant amphibians fromExpand

A reevaluation of early amniote phylogeny
Abstract A new phylogenetic analysis of early amniotes based on 124 characters and 13 taxa (including three outgroups) indicates that synapsids are the sister-group of all other known amniotes. TheExpand

Evolution of humeral microanatomy and lifestyle in amniotes, and some comments on palaeobiological inferences
A study on the most exhaustive taxonomic sample of amniotes (75 extant and nine extinct taxa) of any quantitative work on this topic published so far demonstrates a strong relationship betweenExpand

Evolution of bone microanatomy of the tetrapod tibia and its use in palaeobiological inference
Bone microanatomy appears to track changes in various physiological or ecological properties of the individual or the taxon. Analyses of sections of the tibia of 99 taxa show a highly significant (PExpand

Confirmation of Romer's Gap as a low oxygen interval constraining the timing of initial arthropod and vertebrate terrestrialization
The first terrestrialization of species that evolved from previously aquatic taxa was a seminal event in evolutionary history. For vertebrates, one of the most important terrestrialized groups, thisExpand

First histological and skeletochronological data on temnospondyl growth: palaeoecological and palaeoclimatological implications
Abstract The metoposaurid Dutuitosaurus ouazzoui, from the Carnian (Upper Triassic) of southern Morocco is one of the best known temnospondyls; more than 75 specimens have been found, including 15Expand

Anatomy and relationships of Haptodus garnettensis, a Pennsylvanian synapsid from Kansas
ABSTRACT New, well-preserved specimens of the Upper Pennsylvanian synapsid Haptodus garnettensis from Garnett, Kansas, represent more mature individuals than those available previously and indicateExpand

Evolution of ossification sequences in salamanders and urodele origins assessed through event‐pairing and new methods
SUMMARY Ossification sequences of the skull in extant Urodela and in Permo‐Carboniferous Branchiosauridae have already been used to study the origin of lissamphibians. But most of these studies didExpand

Phylogenetic signal in bone microstructure of sauropsids.
In spite of the fact that the potential usefulness of bone histology in systematics has been discussed for over one and a half centuries, the presence of a phylogenetic signal in the variation ofExpand
