Euskelosaurus
''Euskelosaurus'' ("good leg lizard") is a sauropodomorph dinosaur from the Late Triassic of South Africa and Lesotho. Fossils have only been recovered from the lower Elliot Formation in South Africa and Lesotho, and in one locality in Zimbabwe. History of discovery In 1863, Alfred Brown recovered fossil material consisting of limb bones and vertebrae, in the lower Elliot Formation in the southeastern Free State. In 1866, Thomas Henry Huxley first described ''Euskelosaurus'' from Brown's fossil material, and named the holotype specimen ''Euskelosaurus brownii'' after Brown. Harry Seeley later described ''Euskelosaurus'' in 1894, as did Friedrich von Huene in 1902. Since then, other researchers, including Robert Broom, have mentioned ''Euskelosaurus'' in their papers, although later papers refer to the material under the name ''Plateosauravus''.Yates, A.M.

Plateosauravus
''Plateosauravus'' ("grandfather of ''Plateosaurus''") is a basal plateosaurian of uncertain affinities from the Late Triassic Elliot Formation of South Africa.

Elliot Formation
The Elliot Formation is a geological formation and forms part of the Stormberg Group, the uppermost geological Stratigraphic unit, group that comprises the greater Karoo Supergroup. Outcrops of the Elliot Formation have been found in the northern Eastern Cape, southern Free State (province), Free State, and in the eastern KwaZulu-Natal provinces of South Africa. Outcrops and exposures are also found in several localities in Lesotho such as Qacha's Nek, Qacha's Neck, Hill Top, Quthing, and near the capital, Maseru. The Elliot Formation is further divided into the lower (LEF) and upper (UEF) Elliot formations to differentiate significant Sedimentology, sedimentological differences between these layers. The LEF is dominantly Late Triassic (Norian-Hettangian) in age while the UEF is mainly Early Jurassic (Sinemurian-Pliensbachian) and is tentatively regarded to preserve a continental record of the Triassic–Jurassic extinction event, Triassic-Jurassic boundary in southern Africa.

Plateosauridae
Plateosauridae is a family of plateosaurian sauropodomorphs from the Late Triassic of Europe, Greenland, Africa and Asia. Although several dinosaurs have been classified as plateosaurids over the years, the family Plateosauridae is now restricted to ''Plateosaurus'', ''Yimenosaurus'', ''Euskelosaurus'', and ''Issi''''.'' In another study, Yates (2003) sunk ''Sellosaurus'' into ''Plateosaurus'' (as ''P. gracilis''). Classification Plateosauridae, which was first named by Othniel Charles Marsh in 1895, is a stem-based taxon and it was defined by Sereno, 1998 as all animals more closely related to ''Plateosaurus engelhardti'' than to ''Massospondylus carinatus''. Galton and Upchurch, 2004 proposed the following definition: all animals more closely related to ''Plateosaurus engelhardti'' than to ''Massospondylus carinatus'' and ''Yunnanosaurus huangi''. Yates, 2007 defined it as all animals more closely related to ''Plateosaurus engelhardti'' than to ''Diplodocus longus''. Recent cla ...

Largest Prehistoric Animals
The largest prehistoric animals include both vertebrate and invertebrate species. Many of them are described below, along with their typical range of size (for the general dates of extinction, see the link to each). Many species mentioned might not actually be the largest representative of their clade due to the incompleteness of the fossil record and many of the sizes given are merely estimates since no complete specimen have been found. Their body mass, especially, is largely conjecture because soft tissue was rarely fossilized. Generally the size of extinct species was subject to energetic and biomechanical constraints. Non-mammalian synapsids (Synapsida) Caseasaurs (Caseasauria) The herbivorous ''Alierasaurus'' was the largest caseid and the largest amniote to have lived at the time, with an estimated length around . '' Cotylorhynchus hancocki'' is also large, with an estimated length and weight of at least and more than . Edaphosaurids (Edaphosauridae) The larges ...

Aliwalia Rex
''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''. ''Eucnemesaurus'' was named in 1920 by Egbert Cornelis Nicolaas van Hoepen. The type species is ''Eucnemesaurus fortis''. The specific name means "strong" in Latin. It is based on holotype TrM 119, a partial skeleton including vertebrae, part of a pubis, a femur, and two tibiae. The remains were found by Van Hoepen in the late Carnian- early Norian-age Upper Triassic Lower Elliot Formation of the Slabberts district, Orange Free State, South Africa. Yates assigned the genus to the new family Riojasauridae, with ''Riojasaurus'', usually regarded as a melanorosaurid. ''Aliwalia'' Fossil material now assigned to ''Eucnemesaurus'' was once placed in a separate genus and specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Brown (palaeontologist)
Alfred Brown aka Gogga Brown (26 April 1834 Cirencester - 29 June 1920 Aliwal North) was an English-born South African palaeontologist, archaeologist and naturalist whose contributions to science were considerable. Brown discovered 21 new species of fossil reptiles and dinosaurs, a large number of which were described by Robert Broom and Harry Seeley. The defunct genus '' Browniella'' and some ten fossil species were named in his honour. Brown's fossils included 7 new species of Triassic fishes, some found by other collectors, three of which were named after him. Brown published a solitary article on his finds - "The Dicynodon", appearing in the Cape Monthly Magazine (2nd series, 1874, Vol. 9, pp. 83–89). Despite having had no formal training in palaeontology, archaeology or natural history, Brown possessed an enquiring and orderly mind. Alfred Brown was born on 26 April 1834 in Cirencester, England. Very little is known of Brown's early years. Though he kept a detailed j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...
