Gazella Atlantica
''Gazella atlantica'', the Atlantic gazelle, is an extinct species of gazelle that lived in Northwest Africa during the Late Pleistocene. Taxonomy The Atlantic gazelle was described in 1870 from late Quaternary cave deposits at Jebel Thaya in Algeria. Fossils are relatively common across Algeria and Morocco. The Atlantic gazelle is closely related to '' Gazella tingitana'', another extinct gazelle from the Late Pleistocene of North Africa. Description The Atlantic gazelle was a small species of antelope, estimated at around . It would have been roughly comparable in size to the Speke's gazelle, which is generally considered the smallest living gazelle. Paleoecology Fossils of the Atlantic gazelle have been found alongside those of wildebeest ''(Connochaetes taurinus)'' and hartebeest ''(Alcelaphus buselaphus)'' suggesting a habitat preference for open grasslands. In a published paper, anthropologist Richard G. Klein suggested that the Atlantic gazelle may have persisted into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Hartebeest
The hartebeest (; ''Alcelaphus buselaphus''), also known as kongoni or kaama, is an African antelope. It is the only member of the genus ''Alcelaphus''. Eight subspecies have been described, including two sometimes considered to be independent species. A large antelope, the hartebeest stands just over at the shoulder, and has a typical head-and-body length of . The weight ranges from . It has a particularly elongated forehead and oddly-shaped horns, a short neck, and pointed ears. Its legs, which often have black markings, are unusually long. The coat is generally short and shiny. Coat colour varies by the subspecies, from the sandy brown of the western hartebeest to the chocolate brown of the Swayne's hartebeest. Both sexes of all subspecies have horns, with those of females being more slender. Horns can reach lengths of . Apart from its long face, the large chest and the sharply sloping back differentiate the hartebeest from other antelopes. A conspicuous hump over the ...

Prehistoric Bovids
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megaceroides
''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] |
Camelus Thomasi
''Camelus thomasi'' (also known as Thomas' Camel) is an extinct species of camel from the Early-Mid Pleistocene of North Africa. It is known primarily from Tighennif (Ternifine) in Algeria, as well as Sudan. Fossils from Israel dated to the Late Pleistocene have been included under ''C. thomasi'', but they are now considered to belong to a different species, making ''C. thomasi'' a strictly African species. Description ''Camelus thomasi'' was larger than any living species of camel. Other defining characteristics include pachyostosis especially marked in the mandible, broad molars with strong styles, and several unique cranial features. Some studies have linked it as a possible ancestor to the dromedary, while others suggest it may be more closely related to the Bactrian camel of central Asia. However, a 2018 study revealed such assertions to be lacking any scientific basis, and ''C. thomasi'' appears to not be closely related to any living camel. References {{Taxonbar, ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wildebeest
Wildebeest ( , , ), also called gnu ( or ), are antelopes of the genus ''Connochaetes'' and native to Eastern and Southern Africa. They belong to the family Bovidae, which includes true antelopes, cattle, goats, sheep, and other even-toed horned ungulates. There are two species of wildebeest: the black wildebeest or white-tailed gnu (''C. gnou''), and the blue wildebeest or brindled gnu (''C. taurinus''). Fossil records suggest these two species diverged about one million years ago, resulting in a northern and a southern species. The blue wildebeest remained in its original range and changed very little from the ancestral species, while the black wildebeest changed more as adaptation to its open grassland habitat in the south. The most obvious ways of telling the two species apart are the differences in their colouring and in the way their horns are oriented. In East Africa, the blue wildebeest is the most abundant big-game species; some populations perform an annual mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jules René Bourguignat
Jules René Bourguignat (19 August 1829, Brienne-le-Château, Brienne-Napoléon, Aube – 7 April 1892) was a French malacologist, a scientist who studied mollusks. He served as secretary-general of the ''Société malacologique de France''. He traveled widely, visiting, for example, Lake Tanganyika and North Africa. He reportedly defined 112 new genera and around 2540 new species of mollusks. Taxa Bourguignat named and described many genera and species of mollusks, including: * ''Aspatharia'' Bourguignat, 1885, a genus of freshwater mussel. * ''Bridouxia'' Bourguignat, 1885, a genus of freshwater snail. * ''Lanistes alexandri'' Bourguignat, 1850, a species of freshwater snail. * ''Reymondia'' Bourguignat, 1885, a genus of freshwater snail. * ''Spekia'' Bourguignat, 1879, a genus of freshwater snail.

Speke's Gazelle
Speke's gazelle (''Gazella spekei'') is the smallest of the gazelle species. It is confined to the Horn of Africa, where it inhabits stony brush, grass steppes, and semi deserts. This species has been sometimes regarded as a subspecies of the Dorcas gazelle, though this is now widely disregarded. Severe habitat fragmentation means it is now impossible to assess the natural migratory or nomadic patterns of ''G. spekei''.East 1996 Its numbers are under threat, and despite an increase in population, the IUCN in 2007 announced its status had changed from vulnerable to endangered. A captive population is maintained, and the wild population exists in the lower tens of thousands. As of 2008, this gazelle is classified as endangered under the IUCN Red List. Speke's gazelle is named after John Hanning Speke, a British explorer of Central Africa.
