Were Notosuchia (Pseudosuchia: Crocodylomorpha) warm-blooded? A palaeohistological analysis suggests ectothermy [PDF]
Biological Journal of the Linnean Society, 2020 AbstractMost Notosuchia were active terrestrial predators. A few were semi-aquatic, or were insectivorous, omnivorous or herbivorous. A question relative to their thermometabolism remains to be answered: were Notosuchia warm-blooded? Here we use quantitative bone palaeohistology to answer this question.

Anatomical notes and discussion of the first described aetosaur Stagonolepis robertsoni (Archosauria: Suchia) from the Upper Triassic of Europe, and the use of plesiomorphies in aetosaur biochronology [PDF]
PeerJ, 2018 Stagonolepis robertsoni, from the Late Triassic of Scotland, was the first named aetosaurian. Known mostly from a series of natural molds from two localities, the osteology of this taxon has been difficult to interpret.

Climate constrains the evolutionary history and biodiversity of crocodylians. [PDF]
Nat Commun, 2015 The fossil record of crocodylians and their relatives (pseudosuchians) reveals a rich evolutionary history, prompting questions about causes of long-term decline to their present-day low biodiversity.

Rise of dinosaurs reveals major body-size transitions are driven by passive processes of trait evolution. [PDF]
Proc Biol Sci, 2012 A major macroevolutionary question concerns how long-term patterns of body-size evolution are underpinned by smaller scale processes along lineages.

A LATERAL OSTEODERM FROM KRYPHIOPARMA CAERULA (PSEUDOSUCHIA: AETOSAURIA) FROM THE UPPER TRIASSIC (NORIAN) CHINLE FORMATION OF ARIZONA [PDF]
Lithodendron: The Science and History Journal of Petrified Forest National ParkRecent collecting of fossil vertebrates in the Chinle Formation at Petrified Forest National Park (PEFO) and reinvestigation of historic collections resulted in the recognition of a new aetosaurian taxon, Kryphioparma caerula. Although distinctive, K.

Rediscovered Cranial Material ofVenaticosuchus rusconiiEnables the First Jaw Biomechanics in Ornithosuchidae (Archosauria: Pseudosuchia) [PDF]
Ameghiniana, 2018 During the Triassic period, pseudosuchians presented a broader variety of feeding habits than those seen nowadays, including herbivorous and omnivorous as well as carnivorous diets. Based on their general anatomy, ornithosuchids have been historically proposed to be either hunters or scavengers.

Palaeohistology of Macrospondylus bollensis (Crocodylomorpha: Thalattosuchia: Teleosauroidea) from the Posidonienschiefer Formation (Toarcian) of Germany, with insights into life history and ecology. [PDF]
Anat Rec (Hoboken)Abstract The Posidonienschiefer Formation of southern Germany has yielded an array of incredible fossil vertebrates. One of the best represented clades therein is Teleosauroidea, a successful thalattosuchian crocodylomorph group that dominated the coastlines.

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 ...
