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

open access: yes, 2022
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.

New fossil unveils the dentary anatomy of the rare lepidosauromorph Cargninia enigmatica from the Upper Triassic of Southern Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Nowadays, Lepidosauria is a diverse group represented by squamates and the rhynchocephalian tuatara. However, their origins date back to the end of the Permian Period, when the stem lineages Lepidosauromorpha and Archosauromorpha diverged. Within the lepidosauromorph stem lineage, a few species have been described with unstable phylogenetic ...

The new archosauriform track Pachychirotherium and the stepwise acquisition of digitigrady, cursoriality and erect stance in the group between the Permian and Triassic

open access: yesPalaeontology, Volume 69, Issue 5, September/October 2026.
Abstract Archosauriforms were the most successful reptiles of the Mesozoic, becoming widespread and diverse during the Triassic. Yet, little is known of their origin, although it seems clear that it was before the end‐Permian mass extinction. An additional source of information comes from the early archosauriform footprint record.

The early evolution of rhynchosaurs

open access: yesFrontiers in Ecology and Evolution, 2016
The rhynchosaurian archosauromorphs are an important and diverse group of fossil tetrapods that first appeared during the Early Triassic and probably became extinct during the early Late Triassic (early Norian).

Micro‐CT informed cranial anatomy of the early rhynchosaur Howesia browni, with implications for rhynchosaur skull evolution

open access: yesPapers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Rhynchosaurs are unusual archosauromorph reptiles that lived between the Induan and early Norian (Early to early Late Triassic). They are characterized by their stocky build and broad skull with a beak‐like premaxilla. This rather charismatic configuration is most clearly expressed in Late Triassic hyperodapedontine rhynchosaurids.

Rhynchosaurus articeps (Archosauromorpha, Rhynchosauria) reanalisados através de tomografia computadorizada: Anatomia e Filogenia

open access: yes, 2023
Rhynchosauria compõe um grupo de Archosauromorpha restrito aos depósitos triássicos, sendo que a origem e irradiação do grupo ocorreu no contexto das mudanças faunísticas drásticas causadas pela extinção em massa do Permo-Triássico.

A re-assessment of the osteology and phylogenetic relationships of the enigmatic, large-headed reptile Sphodrosaurus pennsylvanicus (Late Triassic, Pennsylvania, USA) indicates archosauriform affinities

open access: yes, 2022
Most Triassic terrestrial diapsids belong to two clades, Lepidosauromorpha or (the more diverse) Archosauromorpha. Nevertheless, the phylogenetic relationships of some Triassic diapsids have remained uncertain for decades because of the lack of ...
