Cranial morphology of the tanystropheid Macrocnemus bassanii unveiled using synchrotron microtomography. [PDF]

open access: yesSci Rep, 2020
The genus Macrocnemus is a member of the Tanystropheidae, a clade of non-archosauriform archosauromorphs well known for their very characteristic, elongated cervical vertebrae. Articulated specimens are known from the Middle Triassic of Alpine Europe and

Empirical and Bayesian approaches to fossil-only divergence times: A study across three reptile clades. [PDF]

open access: yesPLoS One, 2017
Estimating divergence times on phylogenies is critical in paleontological and neontological studies. Chronostratigraphically-constrained fossils are the only direct evidence of absolute timing of species divergence.

The phylogenetic relationships of basal archosauromorphs, with an emphasis on the systematics of proterosuchian archosauriforms. [PDF]

open access: yesPeerJ, 2016
The early evolution of archosauromorphs during the Permo-Triassic constitutes an excellent empirical case study to shed light on evolutionary radiations in deep time and the timing and processes of recovery of terrestrial faunas after a mass extinction ...

Colobops: a juvenile rhynchocephalian reptile (Lepidosauromorpha), not a diminutive archosauromorph with an unusually strong bite. [PDF]

open access: yesR Soc Open Sci, 2020
Correctly identifying taxa at the root of major clades or the oldest clade-representatives is critical for meaningful interpretations of evolution. A small, partially crushed skull from the Late Triassic (Norian) of Connecticut, USA, originally described

A Preliminary Analysis of Archosauromorph Baraminology [PDF]

open access: yes, 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

The locomotor ecomorphology of Mesozoic marine reptiles

open access: yesPalaeontology, Volume 66, Issue 2, March/April 2023., 2023
Abstract The aftermath of the end‐Permian mass extinction provided ecological opportunities for many groups of reptiles, marking the beginning of reptile dominance of the Mesozoic oceans. Clades such as ichthyosaurs, thalattosuchians, sauropterygians, mosasaurs and turtles evolved a remarkable diversity of ecological niches and became important ...

Relative skull size evolution in Mesozoic archosauromorphs: potential drivers and morphological uniqueness of erythrosuchid archosauriforms

open access: yesPalaeontology, 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 ...

A large osteoderm-bearing rib from the Upper Triassic Kössen Formation (Norian/Rhaetian) of eastern Switzerland [PDF]

open access: yes, 2022
An important component of the Alpine vertebrate record of Late Triassic age derives from the Kössen Formation, which crops out extensively in the eastern Alps.
