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.
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.
[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.
Size compared to a human. Ahvaytum is a small sauropodomorph, estimated to be 3 feet (0.91 m) long and 1 foot (0.30 m) tall. [1] Eoraptor, a close relative from Argentina, is known from a larger and more complete skeleton with a total body length of around 1.3 metres (4.3 ft). [5]
Sauropodomorpha" then roughly translates to "in the likeness of the lizard feet". The first sauropodomorph to be described was Cardiodon, named by Sir Richard Owen, although he did not recognize at the time that it was a dinosaur. [2] Sauropodomorphs were one of the first groups of dinosaurs to appear, originating in the late Triassic period. [3]
Guaibasaurus has since been recovered as a sauropodomorph, possibly allied with Unaysauridae, with Saturnaliidae representing a group of more basal sauropodomorphs. [9] Among taxa at one point considered guaibasaurids, Agnosphitys has been reassigned to Silesauridae , and Eoraptor , Panphagia , Saturnalia and Chromogisaurus are considered ...
Eucnemesaurus (/ j uː k ˌ n iː m ɪ ˈ s ɔːr ə s /; meaning "good tibia lizard", for its robust tibiae) is a basal sauropodomorph dinosaur genus usually considered to be a synonym of Euskelosaurus. Recent study by Yates (2006), however, indicates that it is valid and the same animal as putative "giant herrerasaurid" Aliwalia.
Some analyses have found it to be a basal theropod, [3] [12] while others consider it a basal sauropodomorph. [5] [6] Other members of "Guaibasauridae" (such as Saturnalia) are generally considered to be very basal sauropodomorphs, and may or may not form a clade with Guaibasaurus.
