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.
Plateosaurus is a basal (early) sauropodomorph dinosaur, a so-called "prosauropod". The type species is Plateosaurus trossingensis ; before 2019, that honor was given to Plateosaurus engelhardti , but it was ruled as undiagnostic (i.e. indistinguishable from other dinosaurs) by the ICZN .
Panphagia was described in 2009 by Ricardo N. Martínez and Oscar A. Alcober, both of the Museo de Ciencias Naturales, in San Juan, Argentina. They performed a phylogenetic analysis and found it to be the most basal known sauropodomorph dinosaur: the fossils shared similar features to those of Saturnalia, an early sauropodomorph, including similarities in the ischium, astragalus, and the ...
Antetonitrus is a genus of sauropodiform dinosaur found in the Early Jurassic Elliot Formation of South Africa.The only species is Antetonitrus ingenipes.Sometimes considered a basal sauropod, it is crucial for the understanding of the origin and early evolution of this group.
Name Age Location Description Aganane Formation [1]. Pliensbachian Morocco [1] Up to 1350 tracks, most of them currently undescribed. Includes several new Sauropod morphotypes.
Eoraptor (/ ˈ iː oʊ ˌ r æ p t ər /) is a genus of small, lightly built, basal sauropodomorph dinosaur.One of the earliest-known dinosaurs and one of the earliest sauropodomorphs, it lived approximately 231 to 228 million years ago, [1] during the Late Triassic in Western Gondwana, in the region that is now northwestern Argentina.
Arcusaurus is an extinct genus of sauropodomorph dinosaur from the Early Jurassic (Pliensbachian stage) of South Africa. Arcusaurus was first named by Adam Yates, Matthew Bonnan and Johann Neveling in 2011 and the type species is Arcusaurus pereirabdalorum. The generic name is derived from Latin arcus, "rainbow", a reference to the Rainbow Nation.
[10] [11] Earlier in 2011, Pradhania, a sauropodomorph from India, was tested for the first time in a large cladistic analysis and was found to be a relatively basal massospondylid. [12] Mussaurus and Xixiposaurus may also be included within Massospondylidae.
