Forbes' Quarry
Forbes' Quarry is located on the northern face of the Rock of Gibraltar within the Upper Rock Nature Reserve in the British Overseas Territory of Gibraltar. The area was quarried during the 19th century to supply stone for reinforcing the fortress' military installations. In the course of the quarrying, a limestone cave was found. The second ever Neanderthal discovery was made within this cave when Cpt. Edmund Flint found the skull of an adult female Neanderthal in 1848. Etymology Forbes' Quarry borrows its name from an 18th-century military installation located directly above the cave and known as Forbes' Battery. History Neanderthal discovery An ancient skull (specimen name Gibraltar 1) was found within Forbes' Quarry by Captain Edmund Flint of the Royal Navy in 1848. Being the secretary of the Gibraltar Museum Society (formerly the Gibraltar Scientific Society), he presented his find to the society on 3 March 1848. This was only the second Neanderthal fossil ever fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military History Of Gibraltar During World War II
The military history of Gibraltar during World War II exemplifies Gibraltar's position as a British Empire, British fortress since the early 18th century and as a vital factor in British military strategy, both as a foothold on the Europe, continent of Europe, and as a bastion of Royal Navy, British sea power. During World War II, Gibraltar served a vital role in both the Battle of the Atlantic, Atlantic Theatre and the Mediterranean Theatre of World War II, Mediterranean Theatre, controlling virtually all naval traffic into and out of the Mediterranean Sea from the Atlantic Ocean. In addition to its commanding position, Gibraltar provided a strongly defended harbour from which ships could operate in both the Atlantic and the Mediterranean. Force H, under the command of James Fownes Somerville, Vice-Admiral James Somerville was based in Gibraltar and had the task of maintaining naval superiority and providing a strong escort for convoys to and from the Siege of Malta (1940), ...

Neanderthal 1
Feldhofer 1 or Neanderthal 1 is the scientific name of the 40,000-year-old type specimen fossil of the species ''Homo neanderthalensis'', found in August 1856 in a German cave, the Kleine Feldhofer Grotte in the Neandertal valley, east of Düsseldorf. In 1864 the fossil's description was first published in a scientific magazine and officially named. William King: ''The Reputed Fossil Man of the Neanderthal''. In: ''Quarterly Journal of Science''. Band 1, 1864, S. 88–97Volltext (PDF; 356 kB)/ref> However, the find was not the first Neanderthal fossil discovery. Other Neanderthal fossils had been discovered earlier, but their true nature and significance had not been recognized, and therefore no separate species' name was assigned. The discovery was made by limestone quarry miners. Neanderthal 1 consists of a skullcap, two femora, the three right arm bones, two of the left arm bones, ilium, and fragments of a scapula and ribs. The fossils were given to Johann Carl Fuhlro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of Gibraltar
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganism ...

Limestone Caves
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limestone co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Fossil Sites
This list of fossil sites is a worldwide list of localities known well for the presence of fossils. Some entries in this list are notable for a single, unique find, while others are notable for the large number of fossils found there. Many of the entries in this list are considered Lagerstätten (sedimentary deposits that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues). Lagerstätten are indicated by a note () in the noteworthiness column. Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed. Such sites may have separate entries if they are considered to be more notable than the formation as a whole. In contrast, extensive formations associated with large areas m ...

Neanderthals Of Gibraltar
The Neanderthals in Gibraltar were among the first to be discovered by modern scientists and have been among the most well studied of their species according to a number of extinction studies which emphasize regional differences, usually claiming the Iberian Peninsula partially acted as a “refuge” for the shrinking Neanderthal populations and the Gibraltar population of Neanderthals as having been one of many dwindling populations of archaic human populations, existing just until around 42,000 years ago. Many other Neanderthal populations went extinct around the same time. The skull of a Neanderthal woman, discovered in a quarry in 1848, was only the second Neanderthal skull ever found and the first adult Neanderthal skull to be discovered, eight years before the discovery of the skull for which the species was named in Neandertal, Germany; had it been recognised as a separate species, it might have been called Calpican (or Gibraltarian) rather than Neanderthal Man.

Gibraltar 2
Gibraltar 2, also known as Devil's Tower Child, represented five skull fragments of a male Neanderthal child discovered in the British Overseas Territory of Gibraltar. The discovery of the fossils at the Devil's Tower (Gibraltar), Devil's Tower Mousterian rock shelter was made by archaeologist Dorothy Garrod in 1926. It represented the second Excavation (archaeology), excavation of a Neanderthal skull in Gibraltar, after Gibraltar 1, the second Neanderthal skull ever found (after Engis 2). In the early twenty-first century, Gibraltar 2 underwent reconstruction. History of Gibraltar 1 Prehistoric man resided in Gibraltar, the British Overseas Territory at the southern end of the Iberian Peninsula. The evidence was first found in the Devil's Tower Road area, at Forbes' Quarry, in the north face of the Rock of Gibraltar. This was the site of the 1848 discovery of the first Neanderthal skull by Lieutenant Edmund Flint (d. 12 January 1857) of the Royal Artillery. The fossil, an adult ...

Menopause
Menopause, also known as the climacteric, is the time in women's lives when menstrual periods stop permanently, and they are no longer able to bear children. Menopause usually occurs between the age of 47 and 54. Medical professionals often define menopause as having occurred when a woman has not had any menstrual bleeding for a year. It may also be defined by a decrease in hormone production by the ovaries. In those who have had surgery to remove their uterus but still have functioning ovaries, menopause is not considered to have yet occurred. Following the removal of the uterus, symptoms typically occur earlier. In the years before menopause, a woman's periods typically become irregular, which means that periods may be longer or shorter in duration or be lighter or heavier in the amount of flow. During this time, women often experience hot flashes; these typically last from 30 seconds to ten minutes and may be associated with shivering, sweating, and reddening of the skin. ...

Hyperostosis Frontalis Interna
Hyperostosis frontalis interna is a common, benign thickening of the inner side of the frontal bone of the skull. It is found predominantly in women after menopause and is usually asymptomatic. Mostly frequently it is found as an incidental finding discovered during an X-ray An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation.

Hugh Falconer
Hugh Falconer MD FRS (29 February 1808 – 31 January 1865) was a Scottish geologist, botanist, palaeontologist, and paleoanthropologist. He studied the flora, fauna, and geology of India, Assam,Burma,and most of the Mediterranean islands and was the first to suggest the modern evolutionary theory of punctuated equilibrium. He studied the Siwalik fossil beds, and may also have been the first person to discover a fossil ape. Early life Falconer was the youngest son of David Falconer of Forres, Elginshire. In 1826 Hugh Falconer graduated at the University of Aberdeen, where he studied natural history. Afterward, he studied medicine in the University of Edinburgh, taking the degree of MD in 1829.Arnold, David (2006) ''The Tropics and the Traveling Gaze: India, Landscape, and Science, 1800–1856'' University of Washington Press, Seattlepp. 156–157 During this period he zealously attended the botanical classes of Prof. R.

Charles Lyell
Sir Charles Lyell, 1st Baronet, (14 November 1797 – 22 February 1875) was a Scottish geologist who demonstrated the power of known natural causes in explaining the earth's history. He is best known as the author of ''Principles of Geology'' (1830–33), which presented to a wide public audience the idea that the earth was shaped by the same natural processes still in operation today, operating at similar intensities. The philosopher William Whewell termed this gradualistic view "uniformitarianism" and contrasted it with catastrophism, which had been championed by Georges Cuvier and was better accepted in Europe. The combination of evidence and eloquence in ''Principles'' convinced a wide range of readers of the significance of " deep time" for understanding the earth and environment. Lyell's scientific contributions included a pioneering explanation of climate change, in which shifting boundaries between oceans and continents could be used to explain long-term variati ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
