A new occurrence of the Late Triassic archosaur Smok in southern Poland [PDF]

Acta Palaeontologica Polonica, 2018
Two isolated teeth, a dorsal vertebra, fragments of a humerus and femur, a fragmentary pubic “boot” and part of an ischium shaft, identified here as belonging to a large predatory archosaur were discovered in the Upper Triassic site at Marciszów near ...

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

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 ...

Whole‐body endothermy: ancient, homologous and widespread among the ancestors of mammals, birds and crocodylians

Biological Reviews, Volume 97, Issue 2, Page 766-801, April 2022., 2022
ABSTRACT The whole‐body (tachymetabolic) endothermy seen in modern birds and mammals is long held to have evolved independently in each group, a reasonable assumption when it was believed that its earliest appearances in birds and mammals arose many millions of years apart.

A new proterochampsid archosauriform from the Middle–Upper Triassic of Southern Brazil [PDF]

Acta Palaeontologica Polonica
Proterochampsidae is a clade of carnivorous archosauriforms that lived during the Triassic and is characterized by an elongated rostrum with dorsally oriented external nares, and a unique pes configuration.

Widespread azendohsaurids (Archosauromorpha, Allokotosauria) from the Late Triassic of western USA and India [PDF]

Papers in Palaeontology, 2021
AbstractArchosauromorph reptiles underwent rapid lineage diversification, increases in morphological and body size disparity, and expansion into new adaptive landscapes. Several of the primary early archosauromorph clades (e.g. rhynchosaurs) are easy to differentiate from others because of their characteristic body types, whereas the more lizard‐like ...

How to date a crocodile: estimation of neosuchian clade ages and a comparison of four time‐scaling methods

Palaeontology, Volume 65, Issue 2, March/April 2022., 2022
Abstract Clade ages within the crocodylomorph clade Neosuchia have long been debated. Molecular and morphological studies have yielded remarkably divergent results. Despite recent advances, there has been no comprehensive relative comparison of the major time calibration methods available to estimate clade ages based on morphological data. We used four

On the origin of BAG(3) and its consequences for an expansion of BAG3's role in protein homeostasis

Journal of Cellular Biochemistry, Volume 123, Issue 1, Page 102-114, January 2022., 2022
In our here presented research, we were able to identify possible and highly conserved LC3 interacting region (LIR) motifs within the protein structure of BAG3. These revelations may cast a new light on BAG3's role in proteostasis and autophagy, independent of other receptor and adaptor proteins.

Biology, not environment, drives major patterns in maximum tetrapod body size through time [PDF]

, 2012
Abiotic and biological factors have been hypothesized as controlling maximum body size of tetrapods and other animals through geological time. We analyse the effects of three abiotic factors—oxygen, temperature and land area—on maximum size of Permian ...

Morphology of the temporal skull region in tetrapods: research history, functional explanations, and a new comprehensive classification scheme

Biological Reviews, Volume 96, Issue 5, Page 2229-2257, October 2021., 2021
ABSTRACT The morphology of the temporal region in the tetrapod skull traditionally has been a widely discussed feature of vertebrate anatomy. The evolution of different temporal openings in Amniota (mammals, birds, and reptiles), Lissamphibia (frogs, salamanders, and caecilians), and several extinct tetrapod groups has sparked debates on the ...

Rise of Dinosaurs Reveals Major Body-Size Transitions Are Driven by Passive Processes of Trait Evolution [PDF]

, 2012
A major macroevolutionary question concerns how long-term patterns of body-size evolution are underpinned by smaller scale processes along lineages.
