Pseudosuchian thermometabolism: A review of the past two decades. [PDF]
Anat Rec (Hoboken)Abstract Pseudosuchia, one of the two main clades of Archosauria, is today only represented by some 20 extant species, the crocodilians, representing only a fraction of its extinct diversity. Extant crocodilians are ectotherms but present morphological and anatomical features usually associated with endothermy.

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 PolonicaProterochampsidae 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.

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.

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 ...

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 ...

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 ...

Bone histology of Azendohsaurus laaroussii: Implications for the evolution of thermometabolism in Archosauromorpha [PDF]
Paleobiology, 2019 AbstractThis paper is aimed at constraining the phylogenetic frame of the acquisition of endothermy by Archosauromorpha. We analyzed the bone histology of Azendohsaurus laaroussii. Stylopodial and zeugopodial bones show three tissue types: (1) avascular lamellar zonal bone formed at low growth rates; (2) a scaffold of parallel-fibered bone containing ...
