The saurischian hip structure led Seeley to name them "lizard-hipped" dinosaurs, because they retained the ancestral hip anatomy also found in modern lizards and other reptiles. He named ornithischians "bird-hipped" dinosaurs because their hip arrangement was superficially similar to that of birds, though he did not propose any specific ...
' long ago ') is an extinct genus of probable basal sauropodomorph saurischian dinosaurs from the Late Triassic Popo Agie Formation of Wyoming, United States. The genus contains a single species, A. bahndooiveche, known from fragmentary hindlimb bones. Ahvaytum represents the oldest known named dinosaur of the ancient Laurasian landmass.
Sauropodomorpha is a clade of saurischian dinosaurs that includes the largest land animals to have ever existed on Earth, such as Argentinosaurus, Brachiosaurus, and Patagotitan. The clade "sauropodomorpha" was created based on the earlier-named and slightly more exclusive clade, Sauropoda.
Articles relating to the Saurischia ("reptile-hipped"), one of the two basic divisions of dinosaurs (the other being Ornithischia), classified by their hip structure. Wikispecies has information related to Saurischia .
Sauropodomorpha (/ ˌ s ɔːr ə ˌ p ɒ d ə ˈ m ɔːr f ə / [3] 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.
Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria." [1] In 1887 and 1888 Harry Seeley divided dinosaurs into the two orders Saurischia and Ornithischia, based on their hip structure. [2]
The first dinosaur hall in the museum opened in 1905. [90] [91] The 4th floor includes the following halls: [266] Hall of Vertebrate Origins; Hall of Saurischian Dinosaurs (recognized by their grasping hand, long mobile neck, and the downward/forward position of the pubis bone, they are forerunners of the modern bird) [267]
Sauropoda (/ s ɔː ˈ r ɒ p ə d ə /), whose members are known as sauropods (/ ˈ s ɔːr ə p ɒ d z /; [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.
