Modern crocodilians' hearts are 4-chambered, but are smaller relative to body size and run at lower pressure than those of modern birds and mammals. They also have a pulmonary bypass, which makes them functionally 3-chambered when under water, conserving oxygen. a secondary palate, which allows the animal to eat and breathe at the same time.

Archosaurus (meaning "ruling lizard") is an extinct genus of carnivorous proterosuchid archosauriform reptile. [1] Its fossils are dated to the latest Permian of Russia and Poland, it is one of the earliest known archosauriforms.

"Rauisuchia" is a paraphyletic group of mostly large and carnivorous Triassic archosaurs. [2] Rauisuchians are a category of archosaurs within a larger group called Pseudosuchia, which encompasses all archosaurs more closely related to crocodilians than to birds and other dinosaurs. First named in the 1940s, Rauisuchia was a name exclusive to ...
A study on the nature of the observed variation in morphology and size of skulls of Bagaceratops rozhdestvenskyi is published online by Czepiński (2019), who considers the species Gobiceratops minutus, Lamaceratops tereschenkoi, Platyceratops tatarinovi and Magnirostris dodsoni to be junior synonyms of B. rozhdestvenskyi.
Aetosaurs belong to Pseudosuchia, a clade of archosaurs that includes living crocodilians and is characterized by the distinctive structure of the ankle bones. [dubious – discuss] Aetosaurs were traditionally referred to a (now obsolete) group called the thecodonts, which included all "primitive" crocodilian relatives that lived in the Triassic.
Gregory S. Paul inferred that Lagosuchus was one of the smallest Triassic archosaurs, with a weight of about 167 g, similar in size and ecology to a weasel or ferret. [9] Thomas Holtz estimated that Lagosuchus could have obtained a total length of 1.7 ft (51 cm) and a weight similar to that of a pigeon (50-500 g). [ 10 ]
