sauropodomorpha การใช้

• The Sauropodomorpha is split into Prosauropoda and Sauropoda.
• Sauropodomorpha, of which Neosauropoda is a subclade, first arose in the late Triassic.
• The ornithischia and sauropodomorpha are both.
• Setting aside the basal Saurischia, the rest of the Saurischia are split into the Sauropodomorpha and Theropoda.
• Basal members of Sauropodomorpha are often collectively termed paraphyletic group, the exact phylogeny of which has not been conclusively determined.
• The evolution of a quadrupedal posture occurred four times, among the ancestors of Euornithopoda, Thyreophora, Ceratopsia and Sauropodomorpha.
• In Linnaean taxonomy, Sauropodomorpha ( which means " lizard feet forms " ) is either a suborder or is left unranked.
• Bonaparte placed the two in the same basal sauropodomorph, possibly guaibasaurid, as the family was found to nest in a basal position within Sauropodomorpha.
• Within the Sauropodomorpha, they were present in prosauropods and most sauropods, but became independently lost in two cretaceous sauropod lineages, the Titanosauria and the Rebbachisauridae.
• In 1996, Novas went further by supporting a theropod position for " Herrerasaurus " with a phylogenetic analysis, which placed it closer to Neotheropoda than " Eoraptor " or Sauropodomorpha.
• In Franconia's middle Keuper ( the Feuerletten ) is one of the best known and most common species of dinosaurs of Central Europe : " Plateosaurus engelhardti ", an early representative of the sauropodomorpha.
• "' Sauropodomorpha "'( } }; from Greek, meaning " lizard-footed forms " ) is an extinct clade of long-necked, herbivorous, saurischian dinosaurs that includes the sauropods and their ancestral relatives.
• Langer ( 2004 ) mentioned that this hypothesis was widely accepted, but that more later authors instead preferred to place " Herrerasaurus " as well as " Eoraptor " basal to Theropoda and Sauropodomorpha, a clade called Eusaurischia.
• Because " Chinshakiangosaurus " is a more derived sauropodomorph, this suggests that a wide, cheekless gape may have evolved twice in Sauropodomorpha : once with " Aardonyx " and again with sauropods more advanced than " Chinshakiangosaurus ".
• The hindlimb of " Chilesaurus " had become less adapted to running as shown by a small cnemial crest on the front top of the shinbone, and a broad foot with a weight-bearing first toe . " Chilesaurus " could defend itself with a strong arm, bearing a large first claw which could be extended outwards, just as with basal Sauropodomorpha.
• Although " Buriolestes " superficially resembles the predatory theropod dinosaurs, with jaws lined by finely serrated and slightly curved teeth well-adapted to a carnivorous diet, it in fact is an early member of the otherwise-herbivorous Sauropodomorpha, the group that gave rise to the giant medial condyle on the end of its tibia projects backwards, a distinctive feature ( autapomorphy ) unique to this animal.
