Riojasaurus (meaning "lizard from La Rioja") was a herbivorous sauropodomorph dinosaur named after La Rioja Province in Argentina where it was found in the Los Colorados Formation in the Ischigualasto-Villa Unión Basin by José Bonaparte. It lived during the Late Triassic (Norian stage) and grew to about long. Riojasaurus is the only known riojasaurid to live in South America.

Melanorosaurus (meaning "Black Mountain Lizard", from the Greek melas/, "black", oros/, "mountain" + /, "lizard") is a genus of basal sauropodomorph dinosaur that lived during the Late Triassic period. An omnivore from South Africa, it had a large body and sturdy limbs, suggesting it moved quadrupedally. Its limb bones were massive and heavy like the limb bones of true sauropods.

Yunnanosaurus ( ) is an extinct genus of sauropodomorph dinosaur that lived approximately 199 to 183 million years ago in what is now the Yunnan Province, in China, for which it was named. Yunnanosaurus was a large sized, moderately-built, ground-dwelling, quadrupedal herbivore, that could also walk bipedally, and ranged in size from 7 meters (23 feet) long and 2 m (6.5 ft) high to 4 m (13 ft) high in the largest species.

Eucnemesaurus (; 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.

Jingshanosaurus (meaning "Jingshan lizard") is a genus of sauropodomorph dinosaurs from the early Jurassic period (201.4 to 196.5 million years ago, Hettangian age) of China. The type and only species is Jingshanosaurus xinwaensis. Its maximum weight was around with an adult femur length of . The genus grew up to long.

Blikanasaurus is a genus of sauropodomorph dinosaur from the late Triassic of South Africa. The generic name Blikanasaurus is derived from Greek, meaning "lizard from Blikana". The species name cromptoni is taken from the surname of A.W. "Fuzz" Crompton, an American paleontologist who led numerous field expeditions in Elliot Formation outcrop localities in South Africa. Blikanasaurus is only known from partial hindlimb bones that were recovered from the lower Elliot Formation (LEF) in the Eastern Cape.

Camelotia (meaning "from Camelot") is a large-bodied sauropodomorph from the latest Triassic (Rhaetian) of southwest England. It is best known from a partial postcranial skeleton found in the Westbury Formation and named by Peter M. Galton in 1985. Subsequent work has generally placed Camelotia as a relatively derived sauropodomorph close to the origin of Sauropoda, although its exact position among early non-sauropod sauropodomorphs remains debated. It is sometimes placed in Melanorosauridae as a close relative of Melanorosaurus. With a body length and mass estimated at and , respectively, it

The Melanorosauridae were a family of sauropodomorph dinosaurs which lived during the Late Triassic and Early Jurassic. 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. Since then, these families have undergone numerous revisions. Galton and Upchurch (2004) considered Camelotia, Lessemsaurus, and Melanorosaurus members of the family Melanorosauridae. A more recent study by Yates (2007) indicates that th

Riojasauridae is an extinct family of sauropodomorph dinosaurs from the Late Triassic Period (late Carnian to Norian Ages). It contains the genera Riojasaurus and Eucnemesaurus. The Riojasauridae is considered a stem taxon, and is defined as "the most inclusive clade containing Riojasaurus incertus but not Plateosaurus engelhardti, Massospondylus carinatus, or Anchisaurus polyzelus". Geologic formations containing riojasaurid fossils include the Lower Elliot Formation of Orange Free State, South Africa (where fossils of Eucnemesaurus have been found), and the Los Colorados Formation, in La Rio

Ignavusaurus is a genus of basal sauropodomorph dinosaur that lived during the Early Jurassic in what is now Lesotho. Its fossils were found in the Upper Elliot Formation which is probably Hettangian in age (around 200 million years ago). It was described on the basis of a partial, well preserved articulated skeleton. The type species, I. rachelis, was described in 2010 by Spanish palaeontologist F. Knoll.

Chuxiongosaurus (meaning "Chuxiong lizard") is a genus of basal sauropodomorph dinosaur which lived during the Early Jurassic Period. Fossils of this genus have been found in the Lower Lufeng Formation, Yunnan Province, southern China. Identified from the holotype CMY LT9401 a nearly complete skull (including a lower jaw) with some similarities to Thecodontosaurus, it was described as the "first basal sauropod dinosaur from the Early Jurassic of China," more basal than Anchisaurus. It was named by Lü Junchang, Yoshitsugu Kobayashi, Li Tianguang and Zhong Shimin in 2010, and the type species is

Sauropodiformes (meaning "in the form of a sauropod") is an extinct clade of sauropodomorph dinosaurs. It includes the true sauropods as well as their closest non-sauropod relatives. This clade was named in 2007 by the researcher Paul Sereno.

Kholumolumo (referring to a type of dragon the local Basuto associate with dinosaurs), formerly "Kholumolumosaurus" or "Thotobolosaurus", is an extinct genus of massopodan sauropodomorph dinosaur, which was closely related to Sarahsaurus, from the lower Elliot Formation of Maphutseng, Lesotho. The type species, Kholumolumo ellenbergerorum was formally described in 2020.

Sarahsaurus is a genus of basal sauropodomorph dinosaur which lived during the Early Jurassic period in what is now northeastern Arizona, United States.

Yizhousaurus (meaning "Yizhou lizard", after the Chuxiong Yi Autonomous Region) is a genus of basal sauropodiform dinosaurs which existed in what is now Lufeng Formation, Yunnan Province of southern China during the lower Jurassic period. Identified from a nearly complete and exquisitely preserved skeleton, it is the most complete basal sauropod currently known with intact skull. Although its name was revealed in a 2010 Geological Society of America abstract by Sankar Chatterjee, T. Wang, S.G. Pan, Z. Dong, X.C. Wu, and Paul Upchurch, it wasn't validly named and described until 2018. The type

Lishulong (Traditional Chinese: 栗樹龍 Simplified Chinese : 栗树龙 Pinyin : Lìshùlóng meaning "chestnut tree dragon") is a genus of sauropodiform dinosaur from the Early Jurassic (Sinemurian–Toarcian) Lufeng Formation of China. The type and only species is Lishulong wangi.

Meroktenos is a genus of basal sauropodomorph dinosaur that lived during the Late Triassic period of what is now Lesotho.

Tuebingosaurus (meaning "Tübingen lizard") is an extinct genus of massopodan sauropodomorph dinosaur from the Late Triassic Trossingen Formation of Germany. The genus contains a single species, Tuebingosaurus maierfritzorum, originally identified as a specimen of Plateosaurus.

Gryponyx (meaning "hooked-claw") is an extinct genus of massopod sauropodomorph known from southern Free State, central South Africa.

Sefapanosaurus was an early, herbivorous sauropodomorph dinosaur occurring in the southern regions of Gondwana some 200 million years ago in the Late Triassic or Early Jurassic. The sauropodomorphs were the dominant terrestrial herbivores throughout much of the Mesozoic Era, from their origins in the mid-Triassic (approximately 230 Ma) until their decline and fall at the end of the Cretaceous (approximately 66 Ma). A distinctive feature of this dinosaur is the cross-shaped astragalus or talus bone in its ankle. The generic name is derived from the Sesotho word sefapano, meaning ‘cross’ and the

Schleitheimia (named after the type locality of Schleitheim), is an extinct genus of sauropodiform sauropodomorph dinosaur, from the Gruhalde Member of Klettgau Formation of Switzerland. The type species, Schleitheimia schutzi was formally described in 2020.

Xingxiulong (meaning "Xingxiu Bridge dragon") is a genus of bipedal massopodan sauropodomorph from the Early Jurassic of China. It contains two species; the type species is X. chengi, described by Wang et al. in 2017 from three specimens, two adults and an immature individual, that collectively constitute a mostly complete skeleton. Adults of this species measured long and tall. A second species, X. yueorum, was described by Chen et al. in 2025 based on a partial articulated postcranial skeleton of an adult individual larger than X. chengi.

Musankwa is an extinct genus of massopodan sauropodomorph dinosaurs from the Late Triassic (Norian) Pebbly Arkose Formation of Zimbabwe. The genus contains a single species, Musankwa sanyatiensis, known from an incomplete hindlimb. Musankwa represents the fourth dinosaur genus to be named from Zimbabwe.
