What is the difference between Pseudosuchia and archosaurs?

Pseudosuchia is one of two major divisions of Archosauria, including living crocodilians and all archosaurs more closely related to crocodilians than to birds. Pseudosuchians are also informally known as “crocodilian-line archosaurs”.

Are alligators and lizards the same?

Alligators and lizards have similar shapes, but they’re not exactly the same, so they don’t look alike at all! Not every alligator is a worker, and not every lizard is an adult. Remember, these are reptiles.

What is the difference between Pseudosuchia and crocodilians?

Despite Pseudosuchia meaning “false crocodiles”, the name is a misnomer as true crocodilians are a subset of the group. Contrary to popular belief, crocodilians differ significantly from their ancestors and distant relatives, as Pseudosuchia contains a staggering diversity of reptiles with many different lifestyles.

Are crocodiles and Pseudosuchia related?

The Pseudosuchia branch includes crocodiles and all other archosaurs more closely related to crocodiles than to birds. Pseudosuchians comprise mostly extinct Triassic groups such as phytosaurs, aetosaurs, prestosuchids, rauisuchids, and poposaurs. All were carnivorous except the armoured, herbivorous aetosaurs.

What is the difference between the two groups of archosaurs?

The two major groups of archosaurs are distinguished by differences in the joint of their ankle. The crocodiles and their relatives (Pseudosuchia) have a crurotarsal ankle joint (left), while dinosaurs and pterosaurs (Ornithosuchia) have a mesotarsal ankle joint (right).

Are archosaurs and dinosaurs the same?

Archosaurs (“ruling reptiles”) are members of a subclass that also includes the dinosaurs, the pterosaurs (flying reptiles), and several groups of extinct forms, mostly from the Triassic Period (251 million to 200 million years ago). The true archosaurs are divided into two branches.
