White Pog
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches ...

Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Kromdraai Formation
Kromdraai Conservancy is a protected conservation park located to the south-west of Gauteng province in north-east South Africa. It is in the Muldersdrift area not far from Krugersdorp. Etymology Its name is derived from Afrikaans meaning "Crooked Turn" after a kink in the meandering Crocodile River. History It was established to protect the caves, old gold mines, fossil sites, trout farm and a game reserve in the area. The caves in the area, known as the Sterkfontein caves have an extensive number of fossils and dolomite caverns. A well known fossil site is also named Kromdraai and it, along with such sites as Sterkfontein, Coopers, Swartkrans and Plovers Lake form part of the conservancy. Part of the Kromdraai conservancy also falls within the Cradle of Humankind World Heritage Site, proclaimed by UNESCO in 1998. Places of interest * Wonder Cave * Sterkfontein See also * Kromdraai, Limpopo * Rhino and Lion Nature Reserve, Kromdraai The white lion is a rare color m ...

Swartkrans Formation
Swartkrans is a fossil-bearing cave designated as a South African National Heritage Site, located about from Johannesburg. It is located in the Cradle of Humankind World Heritage Site and is notable for being extremely rich in archaeological material, particularly hominin remains. Fossils discovered in the limestone of Swartkrans include ''Homo ergaster'' (a variety of ''Homo erectus''), ''Paranthropus'' and ''Homo habilis''. The oldest deposits present at the site are believed to be between 1.9 and 2.1 million years old. Noted paleontologist Robert Broom was a frequent digger. He was followed by C. K. 'Bob' Brain, whose excavations at the site inspired his book '' The Hunters or the Hunted?'' in which he demonstrated that instead of being bloodthirsty killer apes, the hominin fossils found at the site were themselves victims of predation by big cats. Originally, it was believed that ''Dinofelis'' was responsible for such killings, though recent evidence suggests that hominids ...

Sterkfontein Formation
Sterkfontein (Afrikaans for ''Strong Spring'') is a set of limestone caves of special interest to paleo-anthropologists located in Gauteng province, about northwest of Johannesburg, South Africa in the Muldersdrift area close to the town of Krugersdorp. The archaeological sites of Swartkrans and Kromdraai are in the same area. Sterkfontein is a South African National Heritage Site and was also declared a World Heritage Site in 2000. The area in which it is situated is known as the Cradle of Humankind. The Sterkfontein Caves are also home to numerous wild African species including ''Belonogaster petiolata'', a wasp species of which there is a large nesting presence. Numerous early hominin remains have been found at the site over the last few decades. These have been attributed to ''Australopithecus'', early ''Homo'' and ''Paranthropus''. History of investigations Modern excavation of the caves began in the late 1890s by limestone miners who noticed the fossils and brought t ...

Calabrian (stage)
Calabrian is a subdivision of the Pleistocene Epoch of the geologic time scale, defined as 1.8 Ma—774,000 years ago ± 5,000 years, a period of ~. The end of the stage is defined by the last magnetic pole reversal (781 ± 5 Ka) and plunge into an ice age and global drying possibly colder and drier than the late Miocene ( Messinian) through early Pliocene (Zanclean) cold period. Originally the Calabrian was a European faunal stage primarily based on mollusk fossils. It has become the second geologic age in the Early Pleistocene. Many of the mammalian faunal assemblages of the Early Pleistocene start in the Gelasian. For example, the Platygonus and other Blancan fauna appear first in the Gelasian. History of the definition of the Calabrian Because sea shells are much more abundant as fossils, 19th- and early-20th-century geo-scientists used the plentiful and well-differentiatable Mollusca (mollusks) and Brachiopods to identify stratigraphic boundaries. Thus the Calabrian was ...

Late Pleistocene
The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The Late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (formerly known as Middle Pleistocene) and succeeded by the officially ratified Greenlandian. The estimated beginning of the Tarantian is the start of the Eemian interglacial period (Marine Isotope Stage 5). It is held to end with the termination of the Younger Dryas, some 10th millennium BC, 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a provisional or "quasi-formal" designation by the International Union of Geological ...

Stratigraphic Unit
A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it. Units must be ''mappable'' and ''distinct'' from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%". Lithostratigraphic units Sequences of sedimentary and volcanic rocks are subdivided the basis of their shared or associated lithology. Formally identified lithostratigraphic units are structured in a hierarchy of lithostratigraphic rank, higher rank units generally comprising two or more units of lower rank. Going from smaller to larger in rank, the main lithostratigraphic ranks are Bed, Member, Formation, Group and Supergroup. Formal names of lithostratigraphic units are assigned by geological surveys. Units of formation or hi ...
