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 member of a group of early herbivores known as "prosauropods". [29] The group is not a monophyletic group (thus given in quotation marks), and most researchers prefer the term basal sauropodomorph. [46] [47] Plateosaurus was the first "prosauropod" to be described, [29] and gives its name to the family Plateosauridae as the ...
The clade "sauropodomorpha" was created based on the earlier-named and slightly more exclusive clade, Sauropoda. This clade was named by Othniel Charles Marsh in 1878 and it translates to "lizard feet", in reference to the fact that sauropods were unique among the dinosaurs known at the time for having five toes, instead of three (such as in ...
Plateosauridae is a family of plateosaurian sauropodomorphs from the Late Triassic of Europe, Greenland, Africa and Asia. [1] [2] Although several dinosaurs have been classified as plateosaurids over the years, the family Plateosauridae is now restricted to Plateosaurus, Yimenosaurus, Euskelosaurus, and Issi [3].
There is one definite example of a small derived sauropodomorph: Anchisaurus, under 50 kg (110 lb), even though it is closer to the sauropods than Plateosaurus and Riojasaurus, which were upwards of 1 t (0.98 long tons; 1.1 short tons) in weight. [51] Evolving from sauropodomorphs, the sauropods were huge.

Pachysauriscus is a genus of plateosaurian sauropodomorpha from the Late Triassic of southern Germany. Although previously synonymized with Plateosaurus, a number of papers published since the early 2000s have cast doubt on this synonymy.
Plateosaurus plieningeri Huene, 1905 Gresslyosaurus (meaning " Amanz Gressly 's lizard") is a genus of plateosaurian sauropodomorph dinosaur that lived during the Late Triassic period , around 214 to 204 million years ago , in France, Germany, Norway , Greenland and Switzerland .
