A Preliminary Analysis of Archosauromorph Baraminology [PDF]
, 2023 Archosauromorpha is a large grouping of reptiles including the Archosauria and other related taxa, such as phytosaurs, rhynchosaurs, and tanystropheids. Phylogenetically, Archosauria contains both crocodilians and birds, as well as several extinct groups

Rapid Initial Morphospace Expansion and Delayed Morphological Disparity Peak in the First 100 Million Years of the Archosauromorph Evolutionary Radiation [PDF]
, 2021 Adaptive radiations have played a major role in generating modern and deep-time biodiversity. The Triassic radiation of the Archosauromorpha was one of the most spectacular vertebrate radiations, giving rise to many highly ecomorphologically varied ...

Papers in Palaeontology, Volume 9, Issue 6, November/December 2023., 2023 Abstract Non‐crocodyliform crocodylomorphs, formerly referred to the informal group ‘Sphenosuchia’, are the earliest known crocodylomorph precursors of extant crocodylians. They are therefore crucial for our understanding of early crocodylian evolution and the origin of typical crocodylian characteristics, such as the formation of a secondary palate ...

Walking—and Running and Jumping—with Dinosaurs and their Cousins, Viewed Through the Lens of Evolutionary Biomechanics [PDF]
, 2022 Archosauria diversified throughout the Triassic Period before experiencing two mass extinctions near its end∼201 Mya, leaving only the crocodile-lineage (Crocodylomorpha) and bird-lineage (Dinosauria) as survivors; along with thepterosaurian flying ...

Palaeontology, Volume 65, Issue 3, May/June 2022., 2022 Abstract Little is known about the large‐scale evolutionary patterns of skull size relative to body size, and the possible drivers behind these patterns, in Archosauromorpha. For example, the large skulls of erythrosuchids, a group of non‐archosaurian archosauromorphs from the Early and Middle Triassic, and of theropod dinosaurs are regarded as ...

An enigmatic new archosauriform from the Carnian-Norian, Upper Triassic, Ischigualasto Formation of northwestern Argentina [PDF]
, 2021 In this contribution we introduce a new Late Triassic archosaur, Incertovenator longicollum gen. et sp. nov., with an unusual combination of character states that are present in certain early avemetatarsalian and pseudosuchian archosaur clades.

Reconstruction of the pelvic girdle and hindlimb musculature of the early tetanurans Piatnitzkysauridae (Theropoda, Megalosauroidea). [PDF]
J AnatPiatnitzkysauridae were Jurassic theropods that represented one of the earliest lineages to have evolved moderate body size. Here, we reconstructed the hindlimb musculature of this clade, allowing a more complete understanding of myological evolution in theropod pelvic appendages. Abstract Piatnitzkysauridae were Jurassic theropods that represented the
