Sauropsida (Greek for "lizard faces") is a clade of amniotes, broadly equivalent to the class Reptilia, though typically used in a broader sense to also include extinct stem-group relatives of modern reptiles and birds (which, as theropod dinosaurs, are nested within reptiles as more closely related to crocodilians than to lizards or turtles).

Feb 22, 2024 · Sauropsida is a taxonomic clade that includes all reptiles, birds, and their extinct relatives like dinosaurs, pterosaurs, and plesiosaurs. The key unifying feature of sauropsids is their skull morphology – specifically the presence of two openings behind the eye socket known as temporal fenestrae.

Sauropsids are a group of land vertebrates which includes all existing reptiles and birds and their fossil ancestors. They are one of the two groups which evolved from egg-laying amniotes in the first part of the Carboniferous period.

Sauropsids and mammals are amniotes, and, unlike amphibians, their full reproductive cycle occurs outside standing water. Birds, among other physiological properties, are homeothermous animals, resembling to mammals and differing from presently living reptiles with …

The Sauropsids. Sauropsida includes most of what was clasically known as "Reptilia" along with birds which are in effect glorified reptiles) and of course dinosaurs. Sauropsids therefore are the bulk of the reptiles plus birds, while Synapsids are the "mammal-like reptiles" plus mammals.

Identify amniotes called synapsids and sauropsids. Give a brief overview of reptile evolution. Explain why reptiles were able to replace amphibians as the dominant land vertebrates.

Diapsid diversity: Diapsids, as generally conceived, are an apomorphy-based group - the sauropsids that ancestrally possess the diapsid pattern of temporal fenestration, They were among the first groups to be studied with the methods of cladistics (See Gauthier, 1984 and …

Sauropsids are a clade of amniotes that include reptiles, birds, and their extinct relatives, characterized by specific features in their skull and other anatomical structures.

Sauropsida ("lizard faces") is a group of amniotes that includes all existing birds and reptiles as well as their fossil ancestors and other extinct relatives. Large land animals are either in this group or in its sister group, Synapsida, which includes mammals and their fossil relatives. This clade includes Parareptilia and other extinct clades.

Sauropsids are a diverse group of mostly egg-laying vertebrate animals. The Sauropsida includes all modern and most extinct "reptiles", but excludes synapsids. Living sauropsids include lizards, snakes, turtles, crocodiles, and birds.
