Coloradisaurus
''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''. Autho ...

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 ...

Glacialisaurus
''Glacialisaurus'' is a genus of sauropodomorph dinosaur. It lived during the Pliensbachian stage of the Early Jurassic period around 186 to 182 million years ago in what is now the central region of the Transantarctic Mountains of Antarctica. It is known from two specimens; the holotype (name-bearing specimen), a partial tarsus (ankle) and metatarsus, and a partial left femur. The fossils were collected by a team led by paleontologist William R. Hammer during a 1990–91 field expedition to the Hanson Formation of Antarctica. They were described in 2007, and made the basis of the new genus and species ''Glacialisaurus hammeri''. The genus name translates as “icy” or "frozen lizard”, and the species name honors Hammer. This dinosaur has been classified as a massospondylid, a group of medium-sized, basal (early diverging or "primitive") sauropodomorphs that existed during the Late Triassic and Early Jurassic on every continent except Australia. Its length has been estim ...

Los Colorados Formation
The Los Colorados Formation is a sedimentary rock formation of the Ischigualasto-Villa Unión Basin, found in the provinces of San Juan and La Rioja in Argentina. The formation dates back to the Norian age of the Late Triassic. The up to thick formation comprises sandstones, siltstones, mudstones and conglomerates with gypsum layers deposited in a fluvial to lacustrine environment. The formation is the uppermost stratigraphic unit of the Agua de la Peña Group, overlying the Lagerstätte of the Ischigualasto Formation. Los Colorados Formation is partly covered by the Cretaceous Cerro Rajado Formation, separated by an unconformity. The formation is known for its fossils of early dinosaurs, including the coelophysoid ''Zupaysaurus'' and the "prosauropods" ''Coloradisaurus'', ''Lessemsaurus'', and '' Riojasaurus''.Weishampel et al., 2004, pp.527-528 Magnetostratigraphic analysis suggests that the Los Colorados Formation was deposited between 227 and 213 million years ago.Kent et ...

Coloradia
''Coloradia'' is a genus of moths of the family Saturniidae. There are nine described species found in Mexico and eastern North America. The genus was first described by C. A. Blake in 1863. These are generally large moths, predominantly grey in colour. The larvae usually feed on pines and members of the genus are commonly called pinemoths, although ''Coloradia pandora'' has been recorded on aspen Aspen is a common name for certain tree species; some, but not all, are classified by botanists in the section ''Populus'', of the '' Populus'' genus.

Sauropodomorpha
Sauropodomorpha ( ; from Greek, meaning "lizard-footed forms") is an extinct clade of long-necked, herbivorous, saurischian dinosaurs that includes the sauropods and their ancestral relatives. Sauropods generally grew to very large sizes, had long necks and tails, were quadrupedal, and became the largest animals to ever walk the Earth. The '' prosauropods,'' which preceded the sauropods, were smaller and were often able to walk on two legs. The sauropodomorphs were the dominant terrestrial herbivores throughout much of the Mesozoic Era, from their origins in the Late Triassic (approximately 230 Ma) until their decline and extinction at the end of the Cretaceous. Description Sauropodomorphs were adapted to browsing higher than any other contemporary herbivore, giving them access to high tree foliage. This feeding strategy is supported by many of their defining characteristics, such as: a light, tiny skull on the end of a long neck (with ten or more elongated cervical vertebrae) ...

Lufengosaurus
''Lufengosaurus'' (, meaning "Lufeng lizard") is a genus of Massospondylidae, massospondylid dinosaur which lived during the Early Jurassic period in what is now southwestern China. Discovery, taxonomy and research During the late 1930s geologist Bien Meinian began to uncover fossils at Shawan, Yunnan, Shawan near Lufeng County, Lufeng in Yunnan province. In 1938 he was joined by paleontologist Yang Zhongjian, at the time better known as "C.C. Young" in the West. In 1940, Yang named remains of a "prosauropod" ''Lufengosaurus huenei''. The generic name refers to Lufeng. The specific name (zoology), specific name honours Yang's old tutor, the German paleontologist Friedrich von Huene. The holotype, Institute of Vertebrate Paleontology and Paleoanthropology, IVPP V15, a partial skeleton, was found in the Lower Lufeng Formation. Originally considered Triassic, this formation is now seen as dating to the Lower Jurassic (Hettangian–Sinemurian). A second species was named by Yan ...

Prosauropoda
Plateosauria is a clade of sauropodomorph dinosaurs which lived during the Late Triassic to the Late Cretaceous. The name Plateosauria was first coined by Gustav Tornier in 1913. The name afterwards fell out of use until the 1980s. Classification Plateosauria is a node-based taxon. In 1998, Paul Sereno defined Plateosauria as the last common ancestor of ''Plateosaurus engelhardti'' and ''Massospondylus carinatus'', and its descendants. Peter Galton and Paul Upchurch in 2004 used a different definition: the last common ancestor of ''Plateosaurus engelhardti'' and ''Jingshanosaurus xinwaensis'', and its descendants. In their cladistic analysis the Plateosauria belonged to the Prosauropoda, and included the Plateosauridae subgroup. In Galton's and Upchurch's study also ''Coloradisaurus'', ''Euskelosaurus'', ''Jingshanosaurus'', ''Massospondylus'', ''Mussaurus'', ''Sellosaurus'', and ''Yunnanosaurus'' proved to be plateosaurians. However, recent cladistic analyses suggest that the ...

José Bonaparte
José Fernando Bonaparte (14 June 1928 – 18 February 2020) was an Argentine paleontologist who discovered a plethora of South American dinosaurs and mentored a new generation of Argentine paleontologists . One of the best-known Argentine paleontologists, he has been described by paleontologist Peter Dodson as "almost singlehandedly ... responsible for Argentina becoming the sixth country in the world in kinds of dinosaurs". Biography Bonaparte was the son of an Italian sailor, with no close connection to Napoleon's House of Bonaparte. He was born in Rosario, Santa Fe, Argentina, and grew up in Mercedes, Buenos Aires. Despite a lack of formal training in paleontology, he started collecting fossils with many friends at an early age, and created a museum in their home town. He later became the curator of the National University of Tucumán, where he was named ''Doctor Honoris causa'' in 1976, and then in the late 1970s became a senior scientist at the Museo Argentino de Cienci ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Sauropoda
Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include ''Brachiosaurus'', ''Diplodocus'', ''Apatosaurus'' and ''Brontosaurus''. The oldest known unequivocal sauropod dinosaurs are known from the Early Jurassic. ''Isanosaurus'' and ''Antetonitrus'' were originally described as Triassic sauropods, but their age, and in the case of ''Antetonitrus'' also its sauropod status, were subsequently questioned. Sauropod-like sauropodomorph tracks from the Fleming Fjord Formation (Greenland) might, however, indicate the occurrence of the group in the Late Triassic. By the Late Jurassic (150 million yea ...
