Gondolin Cave
Gondolin Cave is a fossiliferous dolomitic paleocave system in the Northwest Province, South Africa. The paleocave formed in the Eccles Formation dolomites ( Malmani Subgroup, Chuniespoort Group carbonate-banded iron formation marine platform). Gondolin is currently the only described hominin-bearing fossil site in the Northwest Province-portion of the designated Cradle of Humankind UNESCO World Heritage Site. The cave is located on privately owned land and is not accessible to the public. As is the case with other South African Paleo-cave systems with Pliocene and/or Pleistocene fossil deposits, the system was mined for lime during the early 20th century. As a result, the system has been heavily disturbed and consists of only a small active cave, a series of ''in situ'' remnant cave deposits, and extensive dumpsites of ''ex situ'' calcified sediments produced during mining activities. Site history and excavations No records of the date of lime mining activities at Gondolin, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North West Province, South Africa
North West ( ; ) is a province of South Africa. Its capital is Mahikeng. The province is located to the west of the major population centre and province of Gauteng and south of Botswana. History North West was incorporated after the end of apartheid in 1994, and includes parts of the former Transvaal Province and Cape Province, as well as most of the former bantustan of Bophuthatswana. It was the scene of political violence in Khutsong, Merafong City Local Municipality in 2006 and 2007, after cross-province municipalities were abolished and Merafong Municipality was transferred entirely to North West. Merafong has since been transferred to Gauteng province in 2009. This province is the birthplace of prominent political figures: Lucas Mangope, Moses Kotane, Ahmed Kathrada, Abram Onkgopotse Tiro, Ruth Mompati, J. B. Marks, Aziz Pahad, and Essop Pahad, among others. Law and government The Provincial Government consists of a premier, an executive council of ten minis ...

The Silmarillion
''The Silmarillion'' () is a book consisting of a collection of myths and stories in varying styles by the English writer J. R. R. Tolkien. It was edited, partly written, and published posthumously by his son Christopher in 1977, assisted by Guy Gavriel Kay, who became a fantasy author. It tells of Eä, a fictional universe that includes the Blessed Realm of Valinor, the ill-fated region of Beleriand, the island of Númenor, and the continent of Middle-earth, where Tolkien's most popular works—''The Hobbit'' and ''The Lord of the Rings''—are set. After the success of ''The Hobbit'', Tolkien's publisher, Stanley Unwin, requested a sequel, and Tolkien offered a draft of the writings that would later become ''The Silmarillion''. Unwin rejected this proposal, calling the draft obscure and "too Celtic", so Tolkien began working on a new story that eventually became ''The Lord of the Rings''. ''The Silmarillion'' has five parts. The first, '' Ainulindalë'', tells in mythic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeomagnetism
Paleomagnetism (occasionally palaeomagnetism) is the study of prehistoric Earth's magnetic fields recorded in rocks, sediment, or archeological materials. Geophysicists who specialize in paleomagnetism are called ''paleomagnetists.'' Certain magnetic minerals in rocks can record the direction and intensity of Earth's magnetic field at the time they formed. This record provides information on the past behavior of the geomagnetic field and the past location of tectonic plates. The record of geomagnetic reversals preserved in volcanic and sedimentary rock sequences ( magnetostratigraphy) provides a time-scale that is used as a geochronologic tool. Evidence from paleomagnetism led to the revival of the continental drift hypothesis and its transformation into the modern theory of plate tectonics. Apparent polar wander paths provided the first clear geophysical evidence for continental drift, while marine magnetic anomalies did the same for seafloor spreading. Paleomagnetic dat ...

Biostratigraphy
Biostratigraphy is the branch of stratigraphy which focuses on correlating and assigning relative ages of rock strata by using the fossil assemblages contained within them.Hine, Robert. "Biostratigraphy." ''Oxford Reference: Dictionary of Biology'', 8th ed., Oxford University Press, 2019. The primary objective of biostratigraphy is ''correlation'', demonstrating that a particular horizon in one geological section represents the same period of time as another horizon at a different section. Fossils within these strata are useful because sediments of the same age can look completely different, due to local variations in the sedimentary environment. For example, one section might have been made up of clays and marls, while another has more chalky limestones. However, if the fossil species recorded are similar, the two sediments are likely to have been laid down around the same time. Ideally these fossils are used to help identify biozones, as they make up the basic biostratigraphy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Redunca
Reedbuck is a common name for Africa Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surfac ...n antelopes from the genus ''Redunca''. Bohor reedbucks belong to the family Bovidae and subfamily Reduncinae. Bohor reedbucks are known to be savannah grazers that live near water sources. They have been found in areas like the Bale Mountains National Park in Ethiopia. Southern reedbucks are found near elevated land, including places in South Africa like Natal. The reedbuck is distinguished by a round glandular spot below each ear, with males having forward-curving horns that vary in size and shape among species. There are three recognised species of reedbuck: the southern reedbuck is the largest, while the mountain reedbuck is the smallest. Nhlangwini Natives of South Africa The name of ...

Oreotragus Oreotragus
The klipspringer (; ''Oreotragus oreotragus'') is a small antelope found in eastern and southern Africa. The sole member of its genus and subfamily/tribe, the klipspringer was first described by German zoologist Eberhard August Wilhelm von Zimmermann in 1783. The klipspringer is a small, sturdy antelope; it reaches at the shoulder and weighs from . The coat of the klipspringer, yellowish gray to reddish brown, acts as an efficient camouflage in its rocky habitat. Unlike most other antelopes, the klipspringer has a thick and coarse coat with hollow, brittle hairs. The horns, short and spiky, typically measure . Typically nocturnal, the klipspringer rests during the middle of the day and late at night. A gregarious animal, the klipspringer is monogamous to a much greater extent than other antelopes; individuals of opposite sexes exhibit long-term to lifelong pair bonding. The mates tend to stay as close as within of each other at most times. Males form territories, , in whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homo
''Homo'' () is a genus of great ape (family Hominidae) that emerged from the genus ''Australopithecus'' and encompasses only a single extant species, ''Homo sapiens'' (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include ''Homo erectus'' and ''Homo neanderthalensis''. The oldest member of the genus is ''Homo habilis'', with records of just over 2 million years ago. ''Homo'', together with the genus ''Paranthropus'', is probably most closely related to the species ''Australopithecus africanus'' within ''Australopithecus''.'''' The closest living relatives of ''Homo'' are of the genus ''Pan (genus), Pan'' (chimpanzees and bonobos), with the ancestors of ''Pan'' and ''Homo'' estimated to have diverged around 5.7–11 million years ago during the Late Miocene. ''H. erectus'' appeared about 2 million years ago and spread throughout Africa (deba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and '' funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the " Sonoran Desert fauna" or the " Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word fo ...

In Situ
is a Latin phrase meaning 'in place' or 'on site', derived from ' ('in') and ' ( ablative of ''situs'', ). The term typically refers to the examination or occurrence of a process within its original context, without relocation. The term is used across many disciplines to denote methods, observations, or interventions carried out in their natural or intended environment. By contrast, ' methods involve the removal or displacement of materials, specimens, or processes for study, preservation, or modification in a controlled setting, often at the cost of contextual integrity. The earliest known use of ''in situ'' in the English language dates back to the mid-17th century. In scientific literature, its usage increased from the late 19th century onward, initially in medicine and engineering. The natural sciences typically use methods to study phenomena in their original context. In geology, field analysis of soil composition and rock formations provides direct insights into Earth' ...
