The affinities of the Late Triassic Cryptovaranoides and the age of crown squamates [PDF]
Royal Society Open Science, 2023 Most living reptile diversity is concentrated in Squamata (lizards, including snakes), which have poorly known origins in space and time. Recently, †Cryptovaranoides microlanius from the Late Triassic of the United Kingdom was described as the oldest ...

A new phylogenetic hypothesis of Tanystropheidae (Diapsida, Archosauromorpha) and other “protorosaurs”, and its implications for the early evolution of stem archosaurs [PDF]
PeerJ, 2021 The historical clade “Protorosauria” represents an important group of archosauromorph reptiles that had a wide geographic distribution between the Late Permian and Late Triassic.

The cranial morphology of Tanystropheus hydroides (Tanystropheidae, Archosauromorpha) as revealed by synchrotron microtomography [PDF]
PeerJ, 2020 The postcranial morphology of the extremely long-necked Tanystropheus hydroides is well-known, but observations of skull morphology were previously limited due to compression of the known specimens.

Locomotion and the early Mesozoic success of Archosauromorpha [PDF]
Royal Society Open ScienceThe Triassic was a time of ecological upheaval as life recovered from the Permian-Triassic mass extinction. Archosauromorphs were a key component of the recovery, diversifying substantially during the Triassic and encompassing the origins of dinosaurs ...

The holotype of the basal archosauromorph Prolacerta broomi revisited [PDF]
Acta Palaeontologica Polonica, 2023 Prolacerta broomi is one of the most important of fossil reptiles. First considered as one of the earliest members of squamates, this basal archosauromorph has been used as a model for diapsid morphological evolution ever since its discovery, playing ...

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.
