New tanystropheids (Reptilia: Archosauromorpha) from the Triassic of Europe

Paleontological Journal, 2011
A new prolacertilian species and genus, Augustaburiania vatagini gen. et sp. nov. (Reptilia: Archosauromorpha), from the Lower Triassic of the Don River Basin is described. It is the first representative of the Tanystropheidae in the Eastern Europe and the world oldest member of this family. Another new genus (Protanystropheus gen.

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.

Archosauromorpha: The Crocodylomorpha

2021
The Crocodylomorpha, one of the three main archosaurian clades, form a large and diversified group spanning from the early Late Triassic (Carnian) to the present. During its long evolutionary history, Crocodylomorphs developed three broad adaptations: terrestrial and cursorial in the earliest taxa (the Sphenosuchia) and the Cenozoic Notosuchia ...

Archosauromorpha: From Early Diapsids to Archosaurs

2021
This chapter reviews and summarizes the histological data currently available on the bone histology of early (mainly Permo-Triassic) archosauromorphs, including archosauriforms and pseudosuchian (crurotarsal) archosaurs. Recent research worldwide has considerably expanded our knowledge of this subject.

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 ...

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.
