Concavotectum
''Concavotectum'' is an extinct genus of tselfatiiformes, tselfatiiforme bony fish that lived during the Cenomanian in Morocco and possibly Egypt. It was discovered and named in 2008 and is known from a single well preserved hand-sized skull and a few isolated vertebrae discovered in the Kem Kem Group (Gara Sbaa Formation). The type species, ''C. moroccensis'', was named in 2008''Mesozoic Fishes 4'' (2008) - Homology and Phylogeny, Chapter: A new tselfatiiform teleost from the Upper Cretaceous (Cenomanian) of the Kem Kem beds, Southern Morocco, Publisher: Verlag Dr. F.

Kem Kem Group
The Kem Kem Group (commonly known as the Kem Kem beds) is a geological group in the Kem Kem region of eastern Morocco, whose strata date back to the Cenomanian stage of the Late Cretaceous. Its strata are subdivided into two geological formations, the lower Gara Sbaa Formation and the upper Douira Formation. It is exposed on an escarpment along the Algeria–Morocco border. The unit unconformably overlies Paleozoic marine units of Cambrian, Silurian and Devonian age, and is itself capped by limestone platform rock of Cenomanian-Turonian age. It primarily consists of deltaic deposits. The lower Gara Sbaa Formation primarily consists of fine and medium grained sandstone, while the Douira Formation consists of fining-upwards, coarse-to-fine grained sandstones intercalated with siltstones, variegated mudstones, and occasional thin gypsiferous evaporites. Dinosaur remains are among the fossils that have been recovered from the group.Weishampel, David B; ''et al.'' (2004). "Dinosau ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombing Of Munich In World War II
The bombing of Munich (''Luftangriffe auf München'') took place mainly in the later stages of World War II. Munich was, and is, a significant German city, as much culturally as industrially. Augsburg, thirty-seven miles to the west, was a main centre of diesel engine production (and still is today), and was also heavily bombed during the war. Although some considerable distance from the United Kingdom, Munich is not a difficult city to find from the air, mainly due to its size, and possibly its proximity to the Austrian Alps to the south-east as a visual reference point. Munich was protected (initially) by its distance from the United Kingdom. There were seventy-four air raids on Munich, with 6,632 people killed and 15,800 wounded. Around 90% of the ''Altstadt'' (old city) was severely damaged due to the policy of carpet bombing (''Flächenbombardement''). Munich was considered a special target of allies bombings also for propaganda purposes, in that it was the " movement's cap ...

Vertebra
The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the backbone), and on the other with phylogenetic differences among the vertebrate taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gara Sbaa Formation
''Gara'' (Basque: ''We Are'') is a bilingual (Basque/Spanish) newspaper published in the city of Donostia-San Sebastián in the Basque Autonomous Community. The newspaper's target market comprises the area of the Basque Country, but its circulation is largely constrained to the Southern Basque territory (Spain), since Spanish is mainly used. Gara, the third most-read newspaper in the Basque Autonomous Community and Navarre, was first published on 30 January 1999 as successor to the leftist and Basque nationalist newspaper ''Egin'', which had been shut down by the noted prosecuting judge Baltasar Garzón in a highly controversial move on 15 July 1998. The case was dismissed and defendants acquitted, with the final verdict stating that no illicit activity was engaged by Egin (2009). On 12 March 2004, ETA denied in a communique to Gara and the Basque public broadcaster EITB its involvement in the March 11, 2004 Madrid attacks. In July 2008, the newspaper denounced that its ...

Skull
The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, these two parts are the neurocranium and the viscerocranium ( facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localisation of the direction and distance of sounds. In some animals, such as horned ungulates (mammals with hooves), the skull also has a defensive function by providing the mount (on the front ...
