Langebaanweg
Langebaanweg is a town on the southwest coast of South Africa, in Western Cape Province. It is the location of the air force base AFB Langebaanweg. Langebaanweg has been an important mining center, with its mai minerals consisting of phosphorites, primarily calcium phosphate. The mining uncovered fossils dating from the late Miocene and early Pliocene, approximately 5 million years ago. Fossil species found there include invertebrates and also a type of rhinoceros, as well as a mousebird and a diving petrel. The West Coast Fossil Park includes displays of fossils found in a former phosphate mine. Brett Hendey, formally of the Iziko South African Museum, documented the significance of the Langebaanweg fossil sites. Langebaanweg is also notable as the birthplace of former England cricketer Allan Lamb, who played 79 Tests for his adopted country as well as in the 1987 and 1992 File:1992 Events Collage V1.png, From left, clockwise: 1992 Los Angeles riots, Riots break out across ...

West Coast Fossil Park
The West Coast Fossil Park is a fossil park near Langebaanweg, Western Cape, South Africa, approximately north of Cape Town. The fossil sites of Langebaanweg have exceptionally well-preserved remains of fossil fauna that date to circa 5.2 million years ago. In this period sea levels were higher and many now extinct animals lived in the riverine forests, wooded savanna and along the sea coast near the present day Langebaanweg site. Phosphate mining operations at Langebaanweg uncovered these rich fossil deposits. The fossils include bones of over 200 different animal species. This represents possibly the greatest diversity of five-million-year-old fossils found anywhere in the world. The fossil park was formed after mining operations ceased in 1993. The park is partnered with the Iziko South African Museum. In 1996 the former National Monuments Council declared the site a national monument. With the introduction of the National Heritage Resources Act in 2000 it became a provin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diving Petrel
The diving petrels form a genus, ''Pelecanoides'', of seabirds in the family Procellariidae. There are four very similar species of diving petrels, distinguished only by small differences in the coloration of their plumage, habitat, and bill construction. They are only found in the southern hemisphere. The diving petrels were formerly placed in their own family, the Pelecanoididae. Diving petrels are auk-like small petrels of the southern oceans. The resemblances with the auks are due to convergent evolution, since both families feed by pursuit diving, although some researchers have in the past suggested that the similarities are due to relatedness. Among the Procellariiformes the diving petrels are the family most adapted to life in the sea rather than flying over it, and are generally found closer inshore than other families in the order. Taxonomy The genus ''Pelecanoides'' was introduced in 1799 by the French naturalist Bernard Germain de Lacépède for the common diving pe ...

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Numbers In South Africa
South Africa switched to a closed numbering system effective 16 January 2007. At that time, it became mandatory to dial the full 10-digit telephone number, including the zero in the three-digit area code, for local calls (e.g., 011 must be dialed from within Johannesburg). Area codes within the system are generally organized geographically. All telephone numbers are 9 digits long (but always prefixed by 0 for calls within South Africa), except for certain Telkom special services. When dialed from another country, the "0" is omitted and replaced with the appropriate international access code and the country code +27. Background History Numbers were allocated when South Africa had only four provinces, meaning that ranges are now split across the current nine provinces. South-West Africa (including Walvis Bay) was integrated into the South African numbering plan. However, the territory had already been allocated its own country code by the International Telecommunication U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mousebird
The mousebirds are birds in the order Coliiformes. They are the sister group to the clade Eucavitaves, which includes the Leptosomiformes (the cuckoo roller), Trogoniformes (trogons), Bucerotiformes (hornbills and hoopoes), Piciformes (woodpeckers, toucans, and barbets) and Coraciformes (kingfishers, bee-eaters, rollers, motmots, and todies). This group is now confined to sub-Saharan Africa, and it is the only bird order confined entirely to that continent, with the possible exception of turacos which are considered by some as the distinct order Musophagiformes, and the cuckoo roller, which is the only member of the order Leptosomiformes, and which is found in Madagascar but not mainland Africa. Mousebirds had a wider range in the Paleogene, with a widespread distribution in Europe and North America during the Paleocene. Description Mousebirds are slender greyish or brown birds with soft, hairlike body feathers. They are typically about in body length, with a long, thi ...

Rhinoceros
A rhinoceros (; ; ), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae. (It can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea.) Two of the extant species are native to Africa, and three to South and Southeast Asia. Rhinoceroses are some of the largest remaining megafauna: all weigh at least one tonne in adulthood. They have a herbivorous diet, small brains (400–600 g) for mammals of their size, one or two horns, and a thick (1.5–5 cm), protective skin formed from layers of collagen positioned in a lattice structure. They generally eat leafy material, although their ability to ferment food in their hindgut allows them to subsist on more fibrous plant matter when necessary. Unlike other perissodactyls, the two African species of rhinoceros lack teeth at the front of their mouths; they rely instead on their lips to pl ...

Invertebrates
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Fossils
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Calcium Phosphate
The term calcium phosphate refers to a family of materials and minerals containing calcium ions (Ca2+) together with inorganic phosphate anions. Some so-called calcium phosphates contain oxide and hydroxide as well. Calcium phosphates are white solids of nutritious value and are found in many living organisms, e.g., bone mineral and tooth enamel. In milk, it exists in a colloidal form in micelles bound to casein protein with magnesium, zinc, and citrate–collectively referred to as colloidal calcium phosphate (CCP). Various calcium phosphate minerals are used in the production of phosphoric acid and fertilizers. Overuse of certain forms of calcium phosphate can lead to nutrient-containing surface runoff and subsequent adverse effects upon receiving waters such as algal blooms and eutrophication (over-enrichment with nutrients and minerals). Orthophosphates, di- and monohydrogen phosphates These materials contain Ca2+ combined with , , or : * Monocalcium phosphate, E341 (CAS# 775 ...

Phosphorites
Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P2O5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P2O5. This occurs through washing, screening, de-liming, magnetic separation or flotation. By comparison, the average phosphorus content of sedimentary rocks is less than 0.2%.Blatt, Harvey and Robert J. Tracy, ''Petrology'', Freeman, 1996, 2nd ed. pp. 345–349 The phosphate is present as fluorapatite Ca5(PO4)3F typically in cryptocrystalline masses (grain sizes < 1 μm) referred to as -sedimentary apatite deposits of uncertain origin. It is also present as |
