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 cladeof 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.
Sauria is the clade of diapsids containing the most recent common ancestor of Archosauria (which includes crocodilians and birds) and Lepidosauria (which includes squamates and the tuatara), and all its descendants. [1]
Apr 14, 2021 · It was always going to be a big lift, piecing together the story of how sauropods — the long-necked, lumbering giants of the dinosaur world — developed their remarkable, box-like heads. But Yale paleontologists have done just that.
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.
Sauropoda are an infraorder of saurischian ("lizard-hipped") dinosaurs. They had very long necks, long tails, small heads (in comparison to the rest of their body), and thick, pillar-like legs and peg-like teeth. They are notable for the enormous size of some species. The group includes the largest animals ever to have lived on land.
Oct 5, 2024 · Sauropod, any member of the dinosaur subgroup Sauropoda, marked by large size, a long neck and tail, a four-legged stance, and a herbivorous diet. These reptiles were the largest of all dinosaurs and the largest land animals that ever lived.
