Praemegaceros
''Praemegaceros'' is an extinct genus of deer, known from the Pleistocene and Holocene of Western Eurasia. ''Praemegaceros'' is considered to be a genus of "giant deer", with many species having an estimated body mass of around , considerably larger than most living deer. The genus contains the subgenera ''Praemegaceros,'' ''Orthogonoceros'' and ''Nesoleipoceros''. It has sometimes been synonymised with '' Megaloceros'' and '' Megaceroides'', but is regarded as a distinct genus by most studies. Some authors have considered the genus closely related to ''Megaloceros'', but this has been disputed by others. The earliest species like ''P. obscurus'' and ''P. verticornis'' appeared in Europe between 2 and 1.5 million years ago. The genus was widely distributed across Europe, West and Central Asia during the Early-Middle Pleistocene, with fossils having been discovered in France, Georgia, Germany, England, Greece, Israel, Italy, Romania, Russia Spain, Syria, and Tajikistan.

Insular Dwarfism
Insular dwarfism, a form of phyletic dwarfism, is the process and condition of large animals evolving or having a reduced body size when their population's range is limited to a small environment, primarily islands. This natural process is distinct from the intentional creation of dwarf breeds, called dwarfing. This process has occurred many times throughout evolutionary history, with examples including various species of Dwarf elephant, dwarf elephants that evolved during the Pleistocene epoch, as well as more ancient examples, such as the dinosaurs ''Europasaurus'' and ''Magyarosaurus''. This process, and other "island genetics" artifacts, can occur not only on islands, but also in other situations where an ecosystem is isolated from external resources and breeding. This can include caves, desert oases, isolated valleys and isolated mountains ("sky islands"). Insular dwarfism is one aspect of the more general Foster's rule, "island effect" or "Foster's rule", which posits that w ...

Megaloceros
''Megaloceros'' (from Greek: + , literally "Great Horn"; see also Lister (1987)) is an extinct genus of deer whose members lived throughout Eurasia from the Pleistocene to the early Holocene. The type and only undisputed member of the genus, '' Megaloceros giganteus'', vernacularly known as the "Irish elk" or "giant deer", is also the best known. Fallow deer are thought to be their closest living relatives. ''Megaloceros'' has been suggested to be closely related to other genera of "giant deer", like the East Asian genus '' Sinomegaceros,'' and the European '' Praemegaceros''. Nomenclatural history '' Megaloceros giganteus'' was originally described in 1799 as ''Alce gigantea'' by Johann Friedrich Blumenbach based on specimens found in Ireland. With ''Alce'' being a variant of the genus '' Alces'' used for elk/moose.''Blumenbach J. 1799. Handbuch der Naturgeschichte' (6th Ed.) 16: 697'' In 1827 Joshua Brookes, in a listing of his zoological collection, named the ''Mega ...

Sinomegaceros
''Sinomegaceros'' is an extinct genus of deer known from the Late Pliocene/Early Pleistocene to Late Pleistocene of Central and East Asia. It is considered to be part of the group of "giant deer" (often referred to collectively as members of the tribe Megacerini), with a close relationship to ''Megaloceros''. Many members of the genus are noted for their distinctive palmate antler brow tines. Taxonomy The first species of the genus ''S. ordosianus'' and ''S. pachyosteus'' were named by pioneering Chinese paleontologist Yang Zhongjian, C. C. Young as species of ''Cervus'' in 1932 for material from Zhoukoudian. In a review of the paper the subsequent year Dietrich created the name ''Sinomegaceros'' as a subgenus of ''Cervus'' to house the species, with ''S. pachyosteus'' as the type species. Due to the fact that the name was not published in a formal research paper, it was not widely used for several decades after publication. The species ''S. yabei'' was named in 1938. In the fo ...

Megaceroides Algericus
''Megaceroides algericus'' is an extinct species of deer known from the Late Pleistocene to the Holocene of North Africa. It is one of only two species of deer known to have been native to the African continent, alongside the Barbary stag, a subspecies of red deer. It is considered to be closely related to the giant deer species of Eurasia. Taxonomy The species was first described by Richard Lydekker as ''Cervus algericus'' in 1890 from a maxilla with teeth found near Hammam Maskhoutine in Algeria. The species ''Cervus pachygenys'' was erected for a pachyostotic mandible and an isolated molar found in Algeria by Auguste Pomel in 1892. Léonce Joleaud in two publications in 1914 and 1916 synonymised the two species, and suggested affinities with the giant deer of Europe, and placed it in the newly erected subgenus ''Megaceroides'' within the genus ''Megaceros'' (junior synonym of ''Megaloceros'') as the type species. Camille Arambourg in publications in 1932 and 1938 raised ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corsica
Corsica ( , , ; ; ) is an island in the Mediterranean Sea and one of the Regions of France, 18 regions of France. It is the List of islands in the Mediterranean#By area, fourth-largest island in the Mediterranean and lies southeast of the Metropolitan France#Hexagon, French mainland, west of the Italian Peninsula and immediately north of the Italian island of Sardinia, the nearest land mass. A single chain of mountains makes up two-thirds of the island. , it had a population of 355,528. The island is a Single territorial collectivity, territorial collectivity of France, and is expected to achieve "a form of autonomy" in the near future. The regional capital is Ajaccio. Although the region is divided into two administrative Departments of France, departments, Haute-Corse and Corse-du-Sud, their respective regional and departmental Territorial collectivity, territorial collectivities were merged on 1 January 2018 to form the single territorial collectivity of Corsica.

Cervinae
The Cervinae or the Old World deer, are a subfamily of deer. Alternatively, they are known as the plesiometacarpal deer, due to having lost the parts of the second and fifth metacarpal bones closest to the foot (though retaining the parts away from the foot), distinct from the telemetacarpal deer of the Capreolinae (which have instead retained these parts of those metacarpals, while losing the parts away from the foot instead). Classification and species The following species are recognised in extant genera:Alvarez D. (2007) * Tribe Muntiacini ** Genus '' Elaphodus'' *** Tufted deer (''E. cephalophus'') ** Genus '' Muntiacus'' *** Bornean yellow muntjac (''M. atherodes'') *** Hairy-fronted muntjac (''M. crinifrons'') *** Fea's muntjac (''M. feae'') *** Gongshan muntjac (''M. gongshanensis'') *** Indian muntjac (''M. muntjak'') *** Sumatran muntjac (''M. montanum'') *** Pu Hoat muntjac (''M. puhoatensis'') *** Leaf muntjac (''M. putaoensis'') *** Reeves's muntjac (''M. re ...

Cromer Forest Bed
The Cromer Forest-bed Formation, sometimes known as the Cromer Forest Bed, is a geological formation in Norfolk, England. It consists of river gravels, estuary and floodplain sediments predominantly silt, sand, and muds as well as peat along the coast of northern Norfolk. The Cromer Forest Bed itself varies in age from about 2 to 0.5 million years ago, from the Early Pleistocene to early Middle Pleistocene, though the most fossiliferous strata, such as the West Runton Freshwater Bed date to towards the end of deposition during the early Middle Pleistocene. The fossiliferous West Runton Freshwater Bed is the type locality for the Cromerian Stage of the early Middle Pleistocene between 0.8 and 0.5 million years ago. Some fossils from the Cromer Forest Bed likely come from Early Pleistocene layers, though many finds are found out of stratigraphic context. It is about thick and is exposed in cliff section near the village of West Runton. Paleontology and paleobotany For over a ...
