Draa River
:''Dra is also the abbreviation for the constellation Draco.'' The Draa (, ; also spelled Dra or Drâa, in older sources mostly Darha or Dara, ) is Morocco's longest river, at . It is formed by the confluence of the Dadès River and Imini River. It flows from the High Atlas mountains, initially south-eastward to Tagounite, and from Tagounite mostly westwards to its mouth in the Atlantic Ocean somewhat north of Tan-Tan. In 1971, the (El) Mansour Eddahabi dam was constructed to service the regional capital of Ouarzazate and to regulate the flow of the Draa. Most of the year the part of the Draa after Tagounite falls dry. In the first half of the 20th century, the lowest course of the Draa marked the boundary between the French protectorate of Morocco and the area under Spanish rule. The valley contains the Fezouata formations, which are Burgess shale-type deposits dating to the Lower Ordovician, filling an important preservational window between the common Cambrian ...

French Language
French ( or ) is a Romance languages, Romance language of the Indo-European languages, Indo-European family. Like all other Romance languages, it descended from the Vulgar Latin of the Roman Empire. French evolved from Northern Old Gallo-Romance, a descendant of the Latin spoken in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien language, Francien) largely supplanted. It was also substratum (linguistics), influenced by native Celtic languages of Northern Roman Gaul and by the Germanic languages, Germanic Frankish language of the post-Roman Franks, Frankish invaders. As a result of French and Belgian colonialism from the 16th century onward, it was introduced to new territories in the Americas, Africa, and Asia, and numerous French-based creole languages, most notably Haitian Creole, were established. A French-speaking person or nation may be referred to as Fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burgess Shale-type Preservation
The Burgess Shale of British Columbia is famous for its exceptional preservation of mid-Cambrian organisms. Around 69 other sites have been discovered of a similar age, with soft tissues preserved in a similar, though not identical, fashion. Additional sites with a similar form of preservation are known from the Ediacaran and Ordovician periods. These various shales are of great importance in the reconstruction of the ecosystems immediately after the Cambrian explosion. The taphonomic regime results in soft tissue being preserved, meaning that organisms without conventionally fossilized hard parts can be seen. This provides further insight into the organs of more familiar organisms such as the trilobites. The most famous localities preserving organisms in this fashion are the Canadian Burgess Shale, the Chinese Chengjiang fauna, and the more remote Sirius Passet in north Greenland. However, a number of other localities also exist. Distribution Burgess Shale-type biotas are found p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Askia Ishaq I
Askia Ishaq I, also known as Ishaq Ber (Ishaq the Great), was the ruler of the Songhai Empire from 1539 to 1549, elected Askia following the death of Askia Isma'il. He was the fifth ruler of the Askiya dynasty. Rise to Power Ishaq was born the son of Askia Mohammad I and a Tuareg concubine from Dirma Kulthūm Barda. When Askia Isma'il died on campaign, the leading men in the empire peacefully agreed that Ishaq would be the next ruler. Reign Askia Ishaq was a ruthless and paranoid ruler, inspiring fear and anxiety among the Songhai people. Despite being a devout Muslim, he sent agents to Timbuktu on a regular basis to demand enormous sums of money from the merchants, which is against Islamic law. This damaged the economy of the empire and made him unpopular, thus gaining him many enemies. Askiya Ishaq I was completely ruthless as a ruler and executed any official whom he considered as a threat. The '' Tarikh al-Sudan'' gives this description: "If he imagined anyone was maki ...

Wattasid Dynasty
The Wattasid dynasty (, ''al-waṭṭāsīyūn'') was a ruling dynasty of Morocco. Like the Marinid dynasty, its rulers were of Zenata Berber descent. The two families were related, and the Marinids recruited many viziers from the Wattasids. These viziers eventually assumed the powers of the Sultans, seizing control of the Marinid dynasty's realm when the last Marinid, Abu Muhammad Abd al-Haqq, who had massacred many of the Wattasids in 1459, was murdered during a popular revolt in Fez in 1465. Abu Abd Allah al-Sheikh Muhammad ibn Yahya was the first Sultan of the Wattasid Dynasty. He controlled only the northern part of Morocco, the south being divided into several principalities. The Wattasids were finally supplanted in 1554, after the Battle of Tadla, by the Saadi dynasty princes of Tagmadert who had ruled all of southern Morocco since 1511. Overview Morocco endured a prolonged multifaceted crisis in the 15th and early 16th centuries brought about by economic, political ...

The River Draa
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee'' ...

Geography (Ptolemy)
The ''Geography'' (, , "Geographical Guidance"), also known by its Latin names as the ' and the ', is a gazetteer, an atlas (book), atlas, and a treatise on cartography, compiling the geographical knowledge of the 2nd-century Roman Empire. Originally written by Claudius Ptolemy in Ancient Greek, Greek at Alexandria around 150 AD, the work was a revision of a now-lost atlas by Marinus of Tyre using additional Roman and Parthian Empire, Persian gazetteers and new principles. Its translation – Al-Khwarizmi#Geography, Kitab Surat al-Ard – into Classical Arabic, Arabic by Al-Khwarizmi, Al-Khwarismi in the 9th century was highly influential on the geographical knowledge and cartographic traditions of the Geography and cartography in medieval Islam, Islamic world. Alongside the works of Islamic scholars – and the commentary containing revised and more accurate data by Alfraganus – Ptolemy's work was subsequently highly influential on Middle Ages, Medieval and Renaissanc ...

Acheulean
Acheulean (; also Acheulian and Mode II), from the French after the type site of Saint-Acheul, is an archaeological industry of stone tool manufacture characterized by the distinctive oval and pear-shaped "hand axes" associated with ''Homo erectus'' and derived species such as ''Homo heidelbergensis''. Acheulean tools were produced during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, East Asia and Europe, and are typically found with ''Homo erectus'' remains. It is thought that Acheulean technologies first developed about 2 million years ago, derived from the more primitive Oldowan technology associated with ''Homo habilis''. The Acheulean includes at least the early part of the Middle Paleolithic. Its end is not well defined; if Sangoan (also known as Epi-Acheulean) is included, it may be taken to last until as late as 130,000 years ago. In Europe and Western Asia, early Neanderthals adopted Acheulean technology, transitioning to Mouste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldowan
The Oldowan (or Mode I) was a widespread stone tool archaeological industry during the early Lower Paleolithic spanning the late Pliocene and the first half of the Early Pleistocene. These early tools were simple, usually made by chipping one, or a few, flakes off a stone using another stone. Oldowan tools were used during over a period spanning from 2.9 million years ago up until at least 1.7 million years ago (Ma), by ancient hominins (early humans) across much of Africa. This technological industry was followed by the more sophisticated Acheulean industry (two sites associated with ''Homo erectus'' at Gona in the Afar Region of Ethiopia dating from 1.5 and 1.26 million years ago have both Oldowan and Acheulean tools). The term ''Oldowan'' is taken from the site of Olduvai Gorge in Tanzania, where the first Oldowan stone tools were discovered by the archaeologist Louis Leakey in the 1930s. However, some contemporary archaeologists and palaeoanthropologists prefer to use th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cambrian
The Cambrian ( ) is the first geological period of the Paleozoic Era, and the Phanerozoic Eon. The Cambrian lasted 51.95 million years from the end of the preceding Ediacaran period 538.8 Ma (million years ago) to the beginning of the Ordovician Period 486.85 Ma. Most of the continents lay in the southern hemisphere surrounded by the vast Panthalassa Ocean. The assembly of Gondwana during the Ediacaran and early Cambrian led to the development of new convergent plate boundaries and continental-margin arc magmatism along its margins that helped drive up global temperatures. Laurentia lay across the equator, separated from Gondwana by the opening Iapetus Ocean. The Cambrian marked a profound change in life on Earth; prior to the Period, the majority of living organisms were small, unicellular and poorly preserved. Complex, multicellular organisms gradually became more common during the Ediacaran, but it was not until the Cambrian that fossil diversity seems to rapidly ...
