Pseudosuchia: Masters of survival and diversification.

In the context of an increasing interest for Pseudosuchia, we have compiled a Special Issue, comprising 14 collaborative studies that deepen our understanding of pseudosuchian evolution. These contributions range from the description of a new taxon to exhaustive reviews of thermometabolism, morphological adaptation, systematics, and detailed investigations into ontogeny, paleoneurology, paleohistology, and paleobiology. Through these papers, we explore the evolutionary history of pseudosuchian archosaurs, spotlighting their rise and diversification following the end-Permian mass extinction.

Delivery of evidence-based critical care practices across the United Kingdom: A UK-wide multi-site service evaluation in adult units.

Background: The ICU Liberation Bundle was developed to improve outcomes for patients admitted to critical care. Despite a lack of Bundle adoption in the UK, the individual evidence-based practices (EBPs) within the bundle are defined as standards of care by the UK Intensive Care Society. There are limited data on the delivery of these EBPs.

The consequences of calcium: investigating intracortical reproductive signals in the American alligator for sex determination.

Identifying sex in extinct archosaurs has proven difficult due, in part, to low sample sizes, preservation biases, and methodology. While previous studies have largely focused on morphological traits, here we investigate intracortical signals of egg-shelling in extant alligators. Egg-shelling requires large mobilizations of calcium reserves.

Evaluating extinct pseudosuchian body mass estimates using a femur volume-based model.

The clade Pseudosuchia appeared 250 million years ago. The exclusively semi-aquatic Crocodylia, which includes crocodiles, alligators, caimans, and gharials is the only surviving subgroup. Investigating Crocodylia biology is pivotal for inferring traits of extinct pseudosuchians.
