Gazella Praegaudryi
''Gazella praegaudryi'' was a small species of prehistoric gazelle described from late Miocene sediments near Bou Hanifia, Algeria. It had lightly compressed horn cores and no forward turning metaconid of its P4 premolars, differentiating it from the earlier Miocene ''Gazella'' dentition recovered at Fort Ternan.George A.

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gazelle
A gazelle is one of many antelope species in the genus ''Gazella'' . There are also seven species included in two further genera; '' Eudorcas'' and '' Nanger'', which were formerly considered subgenera of ''Gazella''. A third former subgenus, '' Procapra'', includes three living species of Asian gazelles. Gazelles are known as swift animals. Some can run at bursts as high as or run at a sustained speed of . Gazelles are found mostly in the deserts, grasslands, and savannas of Africa, but they are also found in southwest and central Asia and the Indian subcontinent. They tend to live in herds, and eat fine, easily digestible plants and leaves. Gazelles are relatively small antelopes, most standing high at the shoulder, and are generally fawn-colored. The gazelle genera are ''Gazella'', ''Eudorcas'', and ''Nanger''. The taxonomy of these genera is confused, and the classification of species and subspecies has been an unsettled issue. Currently, the genus ''Gazella'' is widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Algeria
Algeria, officially the People's Democratic Republic of Algeria, is a country in the Maghreb region of North Africa. It is bordered to Algeria–Tunisia border, the northeast by Tunisia; to Algeria–Libya border, the east by Libya; to Algeria–Niger border, the southeast by Niger; to Algeria–Western Sahara border, the southwest by Mali, Mauritania, and Western Sahara; to Algeria–Morocco border, the west by Morocco; and to the north by the Mediterranean Sea. The capital and List of cities in Algeria, largest city is Algiers, located in the far north on the Mediterranean coast. Inhabited since prehistory, Algeria has been at the crossroads of numerous cultures and civilisations, including the Phoenicians, Numidians, Ancient Rome, Romans, Vandals, and Byzantine Greeks. Its modern identity is rooted in centuries of Arab migrations to the Maghreb, Arab Muslim migration waves since Muslim conquest of the Maghreb, the seventh century and the subsequent Arabization, Arabisation ...

Metaconid
Many different terms have been proposed for features of the tooth crown in mammals. The structures within the molars receive different names according to their position and morphology. This nomenclature was developed by Henry Fairfield Osborn in 1907 and is, although with many variations, the one that continues today. Suffixes Tooth structures bear suffixes in order to note the type of structure they are and whether they are present in the upper or lower molars. * The suffix "-cones /-conids" (upper molar/lower molar) is added to the main cusps: Paracone, Metacone, Protocone and Hypocone on the upper molar, and Paraconid, Metaconid, Protoconid, Hypoconid and Entoconid on the lower molar. This name is used for both bunodont and selenodont molars, that is, as many for "buno" pillar-like cusps as for "selenes" crescent-like cusps. * The suffix "-conule /-conulid" (upper molar/lower molar) is added to the secondary cusps. For example, Metaconule, Hypoconulid. * The suffix "-style/-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lothagam
Lothagam is a geological formation located in Kenya, near the southwestern shores of Lake Turkana, from Kanapoi. It is located between the Kerio River, Kerio and Lomunyenkuparet Rivers on an uplifted fault block. Archaeology Bryan Patterson from Harvard University was, in 1967, the first to carry out paleontological research at Lothagam. Meave Leakey has also carried out extensive paleontological research at Lothagam. Miocene and Pliocene Miocene-Pliocene deposits and numerous paleontology, palaeontological finds have been found at Lothagam. Holocene Archaeological sites dating to the Holocene have been found at Lothagam, including the Lothagam Lokam harpoon site and the Lothagam North Pillar Site.

Prehistoric Bovids
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins 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 years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene Mammals Of Africa
The Pleistocene ( ; referred to colloquially as the ''Ice Age'') is the geological epoch that lasted from 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 () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold glacial periods and warmer interglacials, with the sea levels being up to lower than ...
