Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Plateosaurus Panorama
''Plateosaurus'' (probably meaning "broad lizard", often mistranslated as "flat lizard") is a genus of plateosaurid dinosaur that lived during the Late Triassic period, around 214 to 204 million years ago, in what is now Central and Northern Europe. ''Plateosaurus'' is a basal (early) sauropodomorph dinosaur, a so-called "prosauropod". The type species is ''Plateosaurus trossingensis''; before 2019, that honor was given to ''Plateosaurus engelhardti'', but it was ruled as undiagnostic (i.e. indistinguishable from other dinosaurs) by the ICZN. Currently, there are three valid species; in addition to ''P. trossingensis'', ''P. longiceps'' and ''P. gracilis'' are also known. However, others have been assigned in the past, and there is no broad consensus on the species taxonomy of plateosaurid dinosaurs. Similarly, there are a plethora of synonyms (invalid duplicate names) at the genus level. Discovered in 1834 by Johann Friedrich Engelhardt and described three years later by Her ...

Halticosaurus
''Halticosaurus'' (pron.:"HAL-tick-oh-SORE-us") is a dubious genus of theropod dinosaur from the late Triassic period (middle Norian stage, around 215.6–208 million years ago). It is known from a single fragmentary fossil specimen of the species ''H. longotarsus'', found in the Middle Stubensandstein formation of what is present-day Germany The only known specimen was poorly preserved and may have been put together from bones of unrelated animals. Further research would be required to determine which of the bones belonged together, and what kind of theropod ''Halticosaurus'' was. However, most of the bones have been lost. For these reasons, ''Halticosaurus'' is considered to be a '' nomen dubium''. Etymology The name ''Halticosaurus'' comes from the Greek words ' () meaning "good at jumping"/"nimble" and ' () meaning "lizard"; thus "nimble lizard". ''Halticosaurus'' was described and named by Friedrich von HueneHuene, 1908. Die Dinosaurier der Europäischen Triasformati ...

Kanton Baselland
Basel-Landschaft or Basel-Country informally known as Baselland or Baselbiet (; german: Kanton Basel-Landschaft ; rm, Chantun Basilea-Champagna; french: Canton de Bâle-Campagne; it, Canton Basilea Campagna), is one of the 26 cantons forming the Swiss Confederation. It is composed of five districts and its capital city is Liestal. It is traditionally considered a "half-canton", the other half being Basel-Stadt, its urban counterpart. Basel-Landschaft is one of the northernmost cantons of Switzerland. It lies essentially south of the Rhine and north of the Jura Mountains. The canton shares borders with the canton of Basel-Stadt to the north, the canton of Aargau to the east, the canton of Solothurn to the south and the canton of Jura to the west. It shares international borders as well with France and Germany to the north. Together with Basel-Stadt, Basel-Landschaft was part of the canton of Basel, who joined the Old Swiss Confederacy in 1501. Political quarrels and armed c ...

Gresslyosaurus
''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 Switzerland. Taxonomy ''Gresslyosaurus'' was originally dubbed "Dinosaurus gresslyi" by Rütimeyer (1856) on the basis of postcranial remains discovered in the Late Triassic (late Norian-Rhaetian) Knollenmergel of northern Switzerland around 1840 by Amanz Gressly, but that name is a ''nomen nudum'' as it was described in an abstract. ''Dinosaurus'' anyway was already in use for a therapsid, so Rütimeyer (1857) formally described the material as ''Gresslyosaurus ingens''. Lydekker (1888) synonymized ''Gresslyosaurus'' with ''Zanclodon'', but von Huene (1908) removed sauropodomorph material assigned to ''Zanclodon'' (which he assigned to Theropoda) and ''Gresslyosaurus'' along with ''Plateosaurus'' as sauropodomorphs. A number of authors (e.g. Steel 1970) listed ''Gresslyosaurus'' as valid, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterospondylus Restoration
''Pterospondylus'' (meaning "winged vertebra") is a dubious genus of theropod dinosaur from the Late Triassic. It was a coelophysid theropod which lived in what is now Germany (Trossingen Formation). The type species, ''Pterospondylus trielbae'', (derived from "Tri", in reference to the Triassic period, and "Elba", for the Elbe River area), was described by Jaekel in 1913-14 for a single back vertebra found inside the shell of the ''Proganochelys'' turtle.

Massopoda
Massopoda is a clade of sauropodomorph dinosaurs which lived during the Late Triassic to Late Cretaceous epochs. It was named by paleontologist Adam M. Yates of the University of the Witwatersrand in 2007. Massopoda is a stem-based taxon, defined as all animals more closely related to ''Saltasaurus loricatus'' than to ''Plateosaurus engelhardti''. The name Massopoda, ; , is also contraction of Massospondylidae and Sauropoda, two disparate taxa in the clade. Classification Yates assigned the Massopoda to Plateosauria. Within the clade, he assigned the families Massospondylidae (which includes the relatively well-known dinosaur ''Massospondylus'') and Riojasauridae (which includes ''Riojasaurus'') as well as the Sauropoda. The following is a cladogram A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms.

Tuebingosaurus
''Tuebingosaurus'' (meaning " Tübingen lizard") is a genus of massopodan sauropodomorph dinosaur from the Late Triassic Trossingen Formation of Germany. The type and only species is ''T. maierfritzorum'', originally identified as a specimen of '' Plateosaurus''. Discovery and naming The holotype, GPIT-PV-30787, also known as "GPIT IV", is a partial postcranial skeleton. It was discovered in 1922 and stored in the paleontological collection of the university of Tübingen. It was originally assigned to the species ''Gresslyosaurus plieningeri''.von Huene F (1932) Die fossile Reptil-Ordnung Saurischia, ihre Entwicklung und Geschichte. ''Monographien zur Geologie und Palaeontologie'' (Serie 1) 4: 1–361. Later, it was considered an exemplar of ''Plateosaurus'', sometimes being used as reference materials for phylogenetic analyses using its name. However, it actually contains several features with more derived sauropodomorphs, which allowed it to be named as the distinct taxo ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
