The higher-level phylogeny of Archosauria (Tetrapoda: Diapsida) [PDF]

open access: yesJournal of Systematic Palaeontology, 2010

A Mutual Information Based Sequence Distance For Vertebrate Phylogeny Using Complete Mitochondrial Genomes [PDF]

open access: yes, 2007
Traditional sequence distances require alignment. A new mutual information based sequence distance without alignment is defined in this paper. This distance is based on compositional vectors of DNA sequences or protein sequences from complete genomes ...

Avian cerebellar floccular fossa size is not a proxy for flying ability in birds [PDF]

open access: yes, 2013
Extinct animal behavior has often been inferred from qualitative assessments of relative brain region size in fossil endocranial casts. For instance, flight capability in pterosaurs and early birds has been inferred from the relative size of the ...

The first definitive Middle Jurassic atoposaurid (Crocodylomorpha, Neosuchia), and a discussion on the genus Theriosuchus [PDF]

open access: yes, 2015
Atoposaurids were a clade of semiaquatic crocodyliforms known from the Late Jurassic to the latest Cretaceous. Tentative remains from Europe, Morocco, and Madagascar may extend their range into the Middle Jurassic.

open access: yes, 2016
Riojasuchus tenuisceps Bonaparte 1967 is currently known from four specimens, includingtwo complete skulls, collected in the late 1960s from the upper levels of the Los ColoradosFormation (Late Triassic), La Rioja, Argentina.

Do cladistic and morphometric data capture common patterns of morphological disparity? [PDF]

open access: yes, 2015
The distinctly non-random diversity of organismal form manifests itself in discrete clusters of taxa that share a common body plan. As a result, analyses of disparity require a scalable comparative framework.

The taxonomy and anatomy of rauisuchian archosaurs from the Late Triassic of Germany and Poland [PDF]

open access: yes, 2009
The German Late Triassic archosaur Teratosaurus suevicus is a historically important taxon, being the first described rauisuchian. Unfortunately the holotype is a single element, a maxilla, which is poorly preserved and incomplete.

Discrete and continuous character-based disparity analyses converge to the same macroevolutionary signa. A case study from captorhinids [PDF]

open access: yes, 2017
The relationship between diversity and disparity during the evolutionary history of a clade provides unique insights into evolutionary radiations and the biological response to bottlenecks and to extinctions.

Evolutionary relationships and systematics of Atoposauridae (Crocodylomorpha: Neosuchia): implications for the rise of Eusuchia [PDF]

open access: yes, 2016
Atoposaurids are a group of small-bodied, extinct crocodyliforms, regarded as an important component of Jurassic and Cretaceous Laurasian semi-aquatic ecosystems.
