prosauropoda การใช้

• Until recently it was classed as a member of Prosauropoda.
• The Sauropodomorpha is split into Prosauropoda and Sauropoda.
• In their cladistic analysis the Plateosauria belonged to the Prosauropoda, and included the Plateosauridae subgroup.
• However, recent cladistic analyses suggest that the Prosauropoda as traditionally defined is paraphyletic to sauropods.
• Prosauropoda, as currently defined, is a synonym of Plateosauridae as both contain the same taxa by definition.
• Recent phylogenetic analyses by Adam Yates ( 2004, 2006 ) and others firmly places Sauropoda within a paraphyletic " Prosauropoda ".
• Evidence against sauropod ancestry within Prosauropoda comes from the fact that prosauropods had a smaller outer toe on their hind feet than the sauropods.
• Sauropods first appeared in the late Triassic Period, where they somewhat resembled the closely related ( and possibly ancestral ) group " Prosauropoda ".
• This basic division has survived into modern paleontology, with the exception of, again, the Prosauropoda, which Romer included as an infraorder of theropods.
• It was earlier included under the Prosauropoda, but more recently it has been suggested that " Thecodontosaurus " and its relatives preceded the prosauropod-sauropod split.
• It was originally established by Friedrich von Huene in 1932, who broke it into two groups : the basal forms within Prosauropoda, and their descendants, the giant Sauropoda.
• The name Melanorosauridae was first coined by Friedrich von Huene in 1929 . Huene assigned several families of dinosaurs to the infraorder " Prosauropoda " : the Anchisauridae, the Plateosauridae, the Thecodontosauridae, and the Melanorosauridae.
• There is, however, no, which is perhaps surprising-it's two main subtypes, sauropoda and prosauropoda both have their own categories, so it would make sense if there were ( a stub type for it would also be in line with the existing one for theropods ).
• Recent cladistic analyses suggest that the clade Prosauropoda, which was named by Huene in 1920 and was defined by Sereno, in 1998, as all animals more closely related to " Plateosaurus engelhardti " than to " Saltasaurus loricatus ", is a junior synonym of Plateosauridae as both contain the same taxa.
• Later authors, such as Kapff himself, Osborn, and Edwin H . Colbert, incorrectly attributed postcrania of the sauropodomorph dinosaur " Efraasia " to this species or genus and, as a result, it was thought to be a representative of a presumed group of carnivorous Prosauropoda or, alternatively, a very primitive theropod.
• In 1973 Galton assigned " Efraasia " to the Anchisauridae, but he used this name as a paraphyletic group encompassing all " prosauropods " that were not phylogenetic analysis has indicated that " Efraasia " is a basal sauropodomorph, somewhat more derived than " Thecodontosaurus ", but less than either the Prosauropoda ( including " Plateosaurus " ) or the Sauropoda.
