Ngwevu
''Ngwevu'' is a genus of massospondylid sauropodomorph dinosaur from the Lower Jurassic of South Africa. The genus contains one species, ''Ngwevu intloko.'' Discovery and naming The genus ''Ngwevu'' is known from only one specimen, BP/1/4779, which is stored in the Environmental Studies Institute of the University of the Witwatersrand, in Johannesburg, South Africa. The holotype specimen was discovered in 1978 by James William Kitching in the Tevrede Farm, located in Fouriesburg district, South Africa. The strata which preserved the specimen was located in the Clarens Formation, which is Pliensbachian-early Toarcian in age. The specimen was initially considered a specimen of the genus ''Massospondylus'' but in 2019 was designated as a new genus and species ''Ngwevu ntloko'' (pronounced "'Ng-g'where-voo" ; directly from Xhosa 'ngwevu' and 'intloko' meaning "grey skull"). Description ''Ngwevu'' can be distinguished from other sauropodomorphs based on a unique combination of 1 ...

Massospondylidae
Massospondylidae is a family of early massopod dinosaurs that existed in Asia, Africa, North America, South America and AntarcticaHellert, Spencer M. "A New Basal Sauropodomorph from The Early Jurassic Hanson Formation of Antarctica." Geological Society of America Abstracts with Programs,. Vol. 44. No. 5. 2012. during the Late Triassic to the Early Jurassic periods. Several dinosaurs have been classified as massospondylids over the years. The largest cladistic analysis of early sauropodomorphs, which was presented by Apaldetti and colleagues in November 2011, found '' Adeopapposaurus'', '' Coloradisaurus'', '' Glacialisaurus'', ''Massospondylus'', '' Leyesaurus'' and ''Lufengosaurus'' to be massospondylids. This result supports many previous analyses that tested fewer taxa. However, this analysis found the two recently described North American massopods, ''Sarahsaurus'' and '' Seitaad'', and the South African '' Ignavusaurus'' to nest outside Massospondylidae, as opposed to som ...

Massospondylus
''Massospondylus'' ( ; from Greek, (massōn, "longer") and (spondylos, "vertebra")) is a genus of sauropodomorph dinosaur from the Early Jurassic. (Hettangian to Pliensbachian ages, ca. 200–183 million years ago). It was described by Sir Richard Owen in 1854 from remains discovered in South Africa, and is thus one of the first dinosaurs to have been named. Fossils have since been found at other locations in South Africa, Lesotho, and Zimbabwe. Material from Arizona's Kayenta Formation, India, and Argentina has been assigned to the genus at various times, but the Arizonan and Argentinian material are now assigned to other genera. The type species is ''M. carinatus''; seven other species have been named during the past 150 years, but only ''M. kaalae'' is still considered valid. Early sauropodomorph systematics have undergone numerous revisions during the last several years, and many scientists disagree where exactly ''Massospondylus'' lies on the dinosaur evolutiona ...

Ignavusaurus Rachelis
''Ignavusaurus'' is a genus of basal (phylogenetics), basal Sauropodomorpha, 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 Ma (unit), million years ago). It was described on the holotype, basis of a partial, well preserved articulated skeleton. The type species, ''I. rachelis'', was described in 2010 by Spanish palaeontologist F. Knoll. Discovery The holotype was discovered in southern Lesotho near Ha Ralekoala. The fossils were discovered in a mostly articulated state, although the skull was badly damaged, having broken into more than 120 fragments. An unpublished 2002 Ph.D. dissertation referred to the remains, but they were not formally described for several years, and the find remained unpublished. In 2010, the fossils were described by F. Knoll of the Museo Nacional de Ciencias Naturales-CSIC in Madrid as a new taxon, ''Ignavusaurus rach ...

Xhosa Language
Xhosa (, ) also isiXhosa as an endonym, is a Nguni language and one of the official languages of South Africa and Zimbabwe. Xhosa is spoken as a first language by approximately 8.2 million people and by another 11 million as a second language in South Africa, mostly in Eastern Cape, Western Cape, Northern Cape and Gauteng. It has perhaps the heaviest functional load of click consonants in a Bantu language (approximately tied with Yeyi), with one count finding that 10% of basic vocabulary items contained a click. Classification Xhosa is part of the branch of Nguni languages, which also include Zulu, Southern Ndebele and Northern Ndebele. Nguni languages effectively form a dialect continuum of variously mutually intelligible varieties. Xhosa is, to some extent, mutually intelligible with Zulu and with other Nguni languages to a lesser extent. Nguni languages are, in turn, classified under the much larger abstraction of Bantu languages. Geographical distribution ...

Coloradisaurus Brevis
''Coloradisaurus'' (meaning "Los Colorados lizard") is a genus of massospondylid sauropodomorph dinosaur. It lived during the Late Triassic period (Norian stage) in what is now La Rioja Province, Argentina. It is known from two specimens collected from the Los Colorados Formation of the Ischigualasto-Villa Unión Basin. Taxonomy ''Coloradisaurus brevis'' was originally named ''Coloradia brevis'' by José Bonaparte in 1978, but that genus name was preoccupied by the pine moth ''Coloradia'', so it needed a replacement name. In 1983, David Lambert used the name ''Coloradisaurus'' for the genus, but did not indicate it was a replacement or diagnose it. Lambert had gotten the name from Bonaparte in a personal communication and mistakenly thought that Bonaparte had already published it. Peter Galton was the next to use the name ''Coloradisaurus'' in 1990, which he credited to Lambert, when he gave the taxon a diagnosis in his review of prosauropods in '' The Dinosauria''. Aut ...

Sarahsaurus Aurifontanalis
''Sarahsaurus'' is a genus of basal sauropodomorph dinosaur which lived during the Early Jurassic period in what is now northeastern Arizona, United States. Discovery and naming All specimens of ''Sarahsaurus'' were collected from the Lower Jurassic Kayenta Formation near Gold Spring, Arizona. The genus is based on a nearly complete and articulated (with bones still connected to each other) skeleton with a fragmentary and disarticulated skull (holotype, specimen number TMM 43646-2). In addition, a partial skeleton (specimen number TMM 43646-3) as well as a nearly complete skull (specimen number MCZ 8893) was assigned to the genus. The latter specimen was originally referred to as ''Massospondylus'' sp. The complete skull is crushed and split horizontally, separating the skull roof from the palate; this split was caused by periodic swelling and shrinkage of the surrounding clay after burial. While the holotype individual was mature, the second skull indicates a less mature i ...

Leyesaurus Marayensis
''Leyesaurus'' is an extinct genus of massospondylid sauropodomorph dinosaur known from the San Juan Province, northwestern Argentina. Description ''Leyesaurus'' is known from the holotype PVSJ 706, a nearly complete skull with articulated mandible and some postcranial remains ( vertebral column, scapular and pelvic girdles and hindlimb). The skull has a length of 18 centimeters, and ''Leyesaurus'' has been estimated to have been about in length. It was collected from the uppermost part of the Quebrada del Barro Formation of the Marayes-El Carrizal Basin, dating to the Lower Jurassic (based on the similarities between ''Leyesaurus'' and Lower Jurassic sauropodomorphs, like '' Massospondylus'' and ''Adeopapposaurus''). ''Leyesaurus'' was found near the locality Balde de Leyes, in the Caucete Department of San Juan Province. Within Massospondylidae, ''Leyesaurus'' was found to be most closely related to ''Adeopapposaurus''. Etymology ''Leyesaurus'' was f ...

Adeopapposaurus Mognai
''Adeopapposaurus'' (meaning "far eating lizard", in reference to its long neck) is a genus of prosauropod dinosaur from the Early Jurassic Cañón del Colorado Formation of San Juan, Argentina. It was similar to ''Massospondylus''. Four partial skeletons with two partial skulls are known. The type specimen, PVSJ568, includes a skull and most of a skeleton to just past the hips. The form of the bones at the tips of the upper and lower jaws suggests it had keratinous beaks. The fossils now named ''Adeopapposaurus'' were first thought to represent South American examples of ''Massospondylus''; while this is no longer the case, ''Adeopapposaurus'' is classified as a massospondylid. ''Adeopapposaurus'' was described in 2009 by Ricardo N. Martínez. The type species is ''A. mognai'', referring to the Mogna locality where it was found. Phylogeny The following cladogram shows the position of ''Adeopapposaurus'' within Massopoda, according to Oliver W. M. Rauhut and colleagues, 2 ...

Seitaad
''Seitaad'' is a genus of sauropodomorph dinosaur which lived during the Early Jurassic period in what is now southern Utah, United States. ''Seitaad'' is known from an articulated partial postcranial holotype skeleton referred to as UMNH VP 18040. The skeleton is missing its head, neck and tail. It was collected from the Lower Jurassic Navajo Sandstone, the uppermost unit of the Glen Canyon Group, dating to the Pliensbachian stage, near Comb Ridge, San Juan County. A phylogenetic study of ''Seitaad'' found it to be a plateosaur sauropodomorph, placing it in Massospondylidae or alternatively (a less probable position) in Plateosauridae, but its placement within the Plateosauria is not well understood. In a cladistic analysis, presented by Apaldetti and colleagues in November 2011, ''Seitaad'' was found to be within Massopoda, just outside Anchisauria. ''Seitaad'' was first described by Joseph J. W. Sertich and Mark A. Loewen in 2010 and the type species is ''Seitaad ruessi' ...
