Archosauromorpha: Avemetatarsalia – Dinosaurs and Their Relatives

2021
The histological features of Dinosauria and its relatives (Pan-Aves, the stem-group for birds, comprising also pterosaurs and a variety of other basal avemetatarsalians) are surprisingly varied in tissue type and expression, notably with ontogenetic stage and with adult size of the taxon in question.

A New Rhynchosaur (Reptilia, Archosauromorpha) from the Upper Triassic of Eastern North America

Journal of Vertebrate Paleontology, 2020
This paper provides a description and analysis of cranial remains of a rhynchosaur from the Upper Triassic Evangeline Member of the Wolfville Formation of Nova Scotia, Canada. This material, primarily comprising jaw elements, represents the first definitive record of Late Triassic rhynchosaurs from eastern North America.

The phylogenetic position of the Pterosauria within the Archosauromorpha [PDF]

Zoological Journal of the Linnean Society, 1996
In recent years the hypothesis that pterosaurs were the major sister-group of dinosaurs and a closely-linked hypothesis that pterosaurs evolved flight from the ground up have gained general acceptance. A cladistic analysis of the Archosauromorpha using characters presented by previous workers results in a single most parsimonious tree with the ...

The first ctenosauriscid (Reptilia: Archosauromorpha) from the Lower Triassic Of Eastern Europe

Paleontological Journal, 2012
A new Early Triassic thecodont from the Donskaya Luka locality is described. A new species and genus of Rauisuchidae, Bystrowisuchus flerovi gen. et sp. nov., the first East European and earliest known member of the family Ctenosauriscidae is established. The taxonomy and phylogeny of Rauisuchidae and their stratigraphical and geographical distribution

The taxonomy of the South African proterosuchids (Reptilia, Archosauromorpha)

Journal of Vertebrate Paleontology, 1998
ABSTRACT Four different species belonging to three genera of South African proterosuchids have been described: Proterosuchus fergusi (Broom, 1903), Chasmatosaurus vanhoepeni (Haughton, 1924), Elaphrosuchus rubidgei (Broom, 1946), and Chasmatosaurus alexandri (Hoffman, 1965).

The phylogenetic position of the Pterosauria within the Archosauromorpha re-examined

Historical Biology, 2013
A previous analysis of the phylogenetic position of the Pterosauria argued that pterosaurs were not closely related to dinosaurs as is generally accepted, but rather were outside the crown group Archosauria. However, that study was dismissed for the use of inappropriate methods.

A new gliding tetrapod (Diapsida: ?Archosauromorpha) from the Upper Triassic (Carnian) of Virginia

Journal of Vertebrate Paleontology, 2007
A new tetrapod taxon from the Upper Triassic Cow Branch Formation of Virginia is described solely on the basis of computed tomography (CT) scans of 2 individuals. The new form is characterized by the presence of extremely elongate thoracolumbar ribs that presumably supported a gliding membrane in life.

The skull of Cteniogenys, a choristodere (Reptilia: Archosauromorpha) from the Middle Jurassic of Oxfordshire

Zoological Journal of the Linnean Society, 1990
The genus Ctemogenys was originally described as a lizard on the basis of isolated jaw fragments from the Upper Jurassic deposits of Como Bluff, Wyoming. The discovery of new material from a Middle Jurassic locality at Kirtlington, Oxfordshire, showed that Cteniogenys was not a lizard, but an early choristodere. The skull is represented by a collection
