A Preliminary Analysis of Archosauromorph Baraminology [PDF]
, 2023 Archosauromorpha is a large grouping of reptiles including the Archosauria and other related taxa, such as phytosaurs, rhynchosaurs, and tanystropheids. Phylogenetically, Archosauria contains both crocodilians and birds, as well as several extinct groups

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 ...

The palatal dentition of tetrapods and its functional significance [PDF]
, 2017 The presence of a palatal dentition is generally considered to be the primitive condition in amniotes, with each major lineage showing a tendency toward reduction. This study highlights the variation in palatal tooth arrangements and reveals clear trends

The phylogenetic position of the Pterosauria within the Archosauromorpha [PDF]
Zoological Journal of the Linnean Society, 1996 In recent years the hypothesis that pterosaurs were the major sister-group of dinosaurs and a closely-linked hypothesis that pterosaurs evolved flight from the ground up have gained general acceptance. A cladistic analysis of the Archosauromorpha using characters presented by previous workers results in a single most parsimonious tree with the ...

Post-natal parental care in a Cretaceous diapsid from northeastern China [PDF]
, 2015 Post-natal parental care seems to have evolved numerous times in vertebrates. Among extant amniotes, it is present in crocodilians, birds, and mammals. However, evidence of this behavior is extremely rare in the fossil record and is only reported for two

Morphology and function of the palatal dentition in Choristodera [PDF]
, 2016 Choristoderes are a group of extinct freshwater reptiles that were distributed throughout Laurasia from the Middle Jurassic to the Miocene. They are inferred to have had a lifestyle similar to that of extant gavialid crocodiles, but they differed from ...

Sea surface temperature contributes to marine crocodylomorph evolution [PDF]
, 2014 During the Mesozoic and Cenozoic, four distinct crocodylomorph lineages colonized the marine environment. They were conspicuously absent from high latitudes, which in the Mesozoic were occupied by warm-blooded ichthyosaurs and plesiosaurs.
