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). [2]
Sauropoda (/ sɔːˈrɒpədə /), whose members are known as sauropods (/ ˈsɔːrəpɒdz /; [1][2] from sauro- + -pod, ' lizard -footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs.
Sauropoda is a clade of dinosaurs that consists of roughly 300 species of large, long-necked herbivores and includes the largest terrestrial animals ever to exist. The first sauropod species were named in 1842 by Richard Owen, though at the time, he regarded them as unusual crocodilians.
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. [1][2][3] The synapsids are the other group which evolved from amniotes.
Sauropterygia (" lizard flippers ") is an extinct taxon of diverse, aquatic reptiles that developed from terrestrial ancestors soon after the end-Permian extinction and flourished during the Triassic before all except for the Plesiosauria became extinct at the end of that period.
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.
Sauropodomorpha (/ ˌsɔːrəˌpɒdəˈmɔːrfə / [2] SOR-ə-POD-ə-MOR-fə; from Greek, meaning "lizard-footed forms") is an extinct clade of long-necked, herbivorous, saurischian dinosaurs that includes the sauropods and their ancestral relatives.
