Early tetrapod relationships revisited
TLDR
A deep split of early tetrapods between lissamphibian‐ and amniote‐related taxa is detected and is indicated by the results of the original parsimony run ‐ as well as those retrieved from several other treatments of the data set.
Superiority, Competition, and Opportunism in the Evolutionary Radiation of Dinosaurs
TLDR
A comparison of evolutionary rates and morphological disparity of basal dinosaurs and their chief “competitors,” the crurotarsan archosaurs, shows that dinosaurs exhibited lower disparity and an indistinguishable rate of character evolution.
The evolution of Metriorhynchoidea (mesoeucrocodylia, thalattosuchia): an integrated approach using geometric morphometrics, analysis of disparity, and biomechanics
TLDR
This study illustrates the importance of using a varied toolkit of techniques that together with phylogeny, quantitative assessment of diversity, form, and function help elucidate the macroevolutionary pattern of fossil clades.
Dates, nodes and character conflict: Addressing the Lissamphibian origin problem
TLDR
Tests of different crown topologies show that placement of amphibians within lepospondyls is not a significantly worse fit for the whole character set than a close temnospondyl‐lissamphibian relationship, and the latter phylogenetic hypothesis best captures the most coherent assembly of derived lissampshibian apomorphies.

TLDR
It is concluded that dinosaurs did not experience a progressive decline at the end of the Cretaceous, nor was their evolution driven directly by the KTR, and major diversification shifts occurred largely in the first one-third of the group's history.
The radiation of cynodonts and the ground plan of mammalian morphological diversity
TLDR
An enlarged and revised dataset of discrete skeletal characters is used to build a new phylogeny for all main cynodont clades from the Late Permian to the Early Jurassic, and models of morphological diversification in the group are analysed.
A supertree of early tetrapods
TLDR
A genus–level supertree for early tetrapods is built using a matrix representation of 50 source trees, and a second analysis, which excludes source trees superseded by more comprehensive studies, supports a deep phylogenetic split between lissamphibian and amniote total groups.
The first 50 Myr of dinosaur evolution: macroevolutionary pattern and morphological disparity
TLDR
Different aspects of the dinosaur radiation (diversity, disparity and abundance) were decoupled, and the overall macroevolutionary pattern of the first 50 Myr of dinosaur evolution is more complex than often considered.
Resetting the evolution of marine reptiles at the Triassic-Jurassic boundary
TLDR
The end-Triassic mass extinction had a previously unsuspected profound effect in resetting the evolution of apex marine predators of the Mesozoic.
Evolution of morphological disparity in pterosaurs
TLDR
Comparisons of disparity based on discrete cladistic characters show that the basal paraphyletic rhamphorhynchoids (Triassic–Early Cretaceous) occupied a distinct, and relatively small, region of morphospace compared to the derived pterodactyloids (Late Jurassic–Late Cret Jurassic).
