Comparative bone microstructure of three archosauromorphs from the Carnian, Late Triassic Chañares Formation of Argentina [PDF]
Acta Palaeontologica Polonica, 2020 The Chañares Formation exhibits one of the most important archosauriform records of early Carnian ecosystems. Here we present new data on the palaeohistology of Chañares archosauriforms and provide new insights into their paleobiology, as well as ...

Early archosauromorph remains from the Permo-Triassic Buena Vista Formation of north-eastern Uruguay [PDF]
PeerJ, 2015 The Permo-Triassic archosauromorph record is crucial to understand the impact of the Permo-Triassic mass extinction on the early evolution of the group and its subsequent dominance in Mesozoic terrestrial ecosystems.

The anatomy and phylogenetic position of the erythrosuchid archosauriform Guchengosuchus shiguaiensis from the earliest Middle Triassic of China [PDF]
PeerJ, 2019 Erythrosuchidae is a clade of early archosauriform reptiles, which were apex predators in many late Early and Middle Triassic ecosystems, following the Permo-Triassic mass extinction.

Bone Histology of Phytosaur, Aetosaur, and Other Archosauriform Osteoderms (Eureptilia, Archosauromorpha) [PDF]
The Anatomical Record, 2013 ABSTRACTAs in other archosauriforms, phytosaurs and aetosaurs are characterized by the presence of well‐developed osteoderms. Here we provide a comparative study on the microstructure of phytosaur (five taxa) and aetosaur (thirteen taxa) osteoderms.

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

An early Late Triassic long-necked reptile with a bony pectoral shield and gracile appendages [PDF]
Acta Palaeontologica Polonica, 2016 Several partially articulated specimens and numerous isolated bones of Ozimek volans gen. et sp. nov., from the late Carnian lacustrine deposits exposed at Krasiejów in southern Poland, enable a reconstruction of most of the skeleton.

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 ...

Palaeontology, Volume 65, Issue 3, May/June 2022., 2022 Abstract Bite traces on fossil bones are key to deciphering feeding ecology and trophic interactions of vertebrate past ecosystems. However, similarities between traces produced by different carnivorous taxa with similar dentitions, and misidentifications due to equifinality, hinder confident identifications of the bite makers.
