Grus (genus)
''Grus'' is a genus of large birds in the crane family. The genus ''Grus'' was erected by the French zoologist Mathurin Jacques Brisson in 1760. The name ''Grus'' is the Latin word for "crane". The German ornithologist Peter Simon Pallas was sometimes credited with erecting the genus in 1766 but the International Commission on Zoological Nomenclature ruled in 1956 that Brisson should have priority. The genus formerly included additional species. A molecular phylogenetic study published in 2010 found that the genus ''Grus'', as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera, the sandhill crane, the white-naped crane, the sarus crane and the brolga were moved to the resurrected genus ''Antigone'' that had been erected by the German naturalist Ludwig Reichenbach in 1853. The Siberian crane was moved to the resurrected monotypic genus ''Leucogeranus''. Species The genus contains eight species: The HBW/BirdLife and Clements ch ...

Grus Grus
The common crane (''Grus grus''), also known as the Eurasian crane, is a bird of the family Gruidae, the cranes. A medium-sized species, it is the only crane commonly found in Europe besides the demoiselle crane (''Grus virgo'') and the Siberian crane (''Leucogeranus leucogeranus''). Along with the sandhill (''Antigone canadensis'') and demoiselle cranes and the brolga (''Antigone rubicunda''), it is one of only four crane species not currently classified as threatened with extinction or conservation dependent on the species level. Despite the species' large numbers, local extinctions and extirpations have taken place in part of its range, and an ongoing reintroduction project is underway in the United Kingdom. Taxonomy The first formal description of the common crane was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Ardea grus''. The current genus ''Grus'' was erected by the French zoologist Mathurin ...

Grus (constellation)
Grus (, or colloquially ) is a constellation in the southern sky. Its name is Latin for the crane, a type of bird. It is one of twelve constellations conceived by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman. Grus first appeared on a celestial globe published in 1598 in Amsterdam by Plancius and Jodocus Hondius and was depicted in Johann Bayer's star atlas ''Uranometria'' of 1603. French explorer and astronomer Nicolas-Louis de Lacaille gave Bayer designations to its stars in 1756, some of which had been previously considered part of the neighbouring constellation Piscis Austrinus. The constellations Grus, Pavo, Phoenix and Tucana are collectively known as the "Southern Birds". The constellation's brightest star, Alpha Gruis, is also known as Alnair and appears as a 1.7-magnitude blue-white star. Beta Gruis is a red giant variable star with a minimum magnitude of 2.3 and a maximum magnitude of 2.0. Six star systems have been foun ...

Grus (geology)
Grus is an accumulation of angular, coarse-grained fragments (particles of sand and gravel) resulting from the granular disintegration by the processes of chemical and mechanical weathering of crystalline rocks (most notably granitoids) generally in an arid or semiarid region. Grus sand, when cemented into a sandstone, will form an arkose. Within a European context most of the saprolite mantles of Late Cenozoic age are made up grus, contrasting with Mesozoic and Early Cenozoic saprolites made up of kaolinitic and ferrallitic Ferrallitisation is the process in which rock is changed into a soil consisting of clay ( kaolinite) and sesquioxides, in the form of hydrated oxides of iron and aluminium.
