Pafuri
The Makuleke Contractual Park or Pafuri Triangle constitutes the northernmost section of the Kruger National Park, South Africa, and comprises approximately 240 square kilometres of land. The "triangle" is a wedge of land created by the confluence of the Limpopo and Luvuvhu Rivers at the tripoint Crook's Corner, which forms a border with Zimbabwe along the Limpopo River. It is a natural choke point for wildlife crossing from North to South and back, and forms a distinct ecological region. Pafuri ( Tsonga) is derived from Mphaphuli, the dynastic name of Venda chieftains who ruled locally, while the Luvuvhu River is named after a ''Combretum'' tree (Venda: ''muvuvhu'', Tsonga Rivubye) growing on its banks. Geological history The Makuleke region carries a remarkable geological and natural heritage that makes this region of interest to geographers and historians. Some rocks in the area have been dated to over 250 million years old. In the bottom of Lanner Gorge are rocks that appear ...

Kruger National Park
Kruger National Park is a South African National Park and one of the largest game reserves in Africa. It covers an area of in the provinces of Limpopo and Mpumalanga in northeastern South Africa, and extends from north to south and from east to west. The administrative headquarters are in Skukuza. Areas of the park were first protected by the government of the South African Republic in 1898, and it became South Africa's first national park in 1926. To the west and south of the Kruger National Park are the two South African provinces of Limpopo and Mpumalanga, respectively. To the north is Zimbabwe, and to the east is Mozambique. It is now part of the Great Limpopo Transfrontier Park, a peace park that links Kruger National Park with the Gonarezhou National Park in Zimbabwe, and with the Limpopo National Park in Mozambique. The park is part of the Kruger to Canyons Biosphere, an area designated by the United Nations Educational, Scientific and Cultural Organization (U ...

Levubu River
The Levubu River or Levuvhu ( ts, Rivubye; ve, Luvuvhu) is located in the northern Limpopo province of South Africa. Some of its tributaries, such as the Mutshindudi River and Mutale River rise in the Soutpansberg Mountains. The Luvuvhu River flows for about 200 km through a diverse range of landscapes before it joins the Limpopo River in the Fever Tree Forest area, near Pafuri in the Kruger National Park. A Zambezi shark (''Carcharhinus leucas'') was caught at the confluence of the Limpopo and Luvuvhu Rivers in July 1950. Zambezi sharks tolerate fresh water and can travel far up rivers like the Limpopo. The river's crocodile population extends to its upper reaches at Thohoyandou.

Lanner Gorge
The Lanner Gorge is located in the far North of the Kruger National Park. It forms the boundary between the Kruger National Park to the South and the Makuleke Concession to the North. It was carved by the Luvuvhu River and is at some points more than 150 m deep. Description Lanner Gorge is approximately 11 km long and is carved into sandstones and shales. Geology The uppermost rocks are gravels which are thought to be Cretaceous in age while the basal shales are thought to be Permian in age. The majority of the walls appear to be composed of Triassic and Jurassic aged sandstones formed under arid conditions. The Luvuvhu river has eroded through the sandstones and shales and formation is still active as is evidenced by the many collapsed boulders in the river bed. Dinosaur fossils have been discovered in the walls of Lanner Gorge and rocks in the surrounding region. Desert roses are also common in the Triassic and Jurassic-aged rocks.

Limpopo
Limpopo is the northernmost province of South Africa. It is named after the Limpopo River, which forms the province's western and northern borders. The capital and largest city in the province is Polokwane, while the provincial legislature is situated in Lebowakgomo. The province is made up of 3 former homelands of Lebowa, Gazankulu and Venda and the former parts of the Transvaal province. The Limpopo province was established as one of the new nine provinces after South Africa's first democratic election on the 27th of April 1994. The province's name was first "Northern Transvaal", later changed to "Northern Province" on the 28th of June 1995, together with two other provinces. The name was later changed again in 2002 to the Limpopo province. Limpopo is made up of 3 main ethnic groups namely; Pedi people, Tsonga and Venda people. Traditional leaders and chiefs still form a strong backbone of the province's political landscape. Established in terms of the Limpopo House o ...

Euskelosaurus
''Euskelosaurus'' ("good leg lizard") is a sauropodomorph dinosaur from the Late Triassic of South Africa and Lesotho. Fossils have only been recovered from the lower Elliot Formation in South Africa and Lesotho, and in one locality in Zimbabwe. History of discovery In 1863, Alfred Brown recovered fossil material consisting of limb bones and vertebrae, in the lower Elliot Formation in the southeastern Free State. In 1866, Thomas Henry Huxley first described ''Euskelosaurus'' from Brown's fossil material, and named the holotype specimen ''Euskelosaurus brownii'' after Brown. Harry Seeley later described ''Euskelosaurus'' in 1894, as did Friedrich von Huene in 1902. Since then, other researchers, including Robert Broom, have mentioned ''Euskelosaurus'' in their papers, although later papers refer to the material under the name '' Plateosauravus''.Yates, A.M.

Mesozoic
The Mesozoic Era ( ), also called the Age of Reptiles, the Age of Conifers, and colloquially as the Age of the Dinosaurs is the second-to-last era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods. It is characterized by the dominance of archosaurian reptiles, like the dinosaurs; an abundance of conifers and ferns; a hot greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest well-documented mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, pterosaurs, mosasaurs, and plesiosaurs. The Mesozoic was a time of significant tectonic, climatic, and evolutionary activity. The era witnessed the gradual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conifers
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adaptat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycads
Cycads are seed plants that typically have a stout and woody ( ligneous) trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long. Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group. Cycads are gymnosperms (naked-seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones (strobili), somewhat similar to conifer cones. Cycads have been reported to fix nitrogen in associ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassi ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permian–Triassic Extinction Event
The Permian–Triassic (P–T, P–Tr) extinction event, also known as the Latest Permian extinction event, the End-Permian Extinction and colloquially as the Great Dying, formed the boundary between the Permian and Triassic geologic periods, as well as between the Paleozoic and Mesozoic eras, approximately 251.9 million years ago. It is the Earth's most severe known extinction event, with the extinction of 57% of biological families, 83% of genera, 81% of marine species and 70% of terrestrial vertebrate species. It was the largest known mass extinction of insects. There is evidence for one to three distinct pulses, or phases, of extinction. The scientific consensus is that the main cause of extinction was the large amount of carbon dioxide emitted by the volcanic eruptions that created the Siberian Traps, which elevated global temperatures, and in the oceans led to widespread anoxia and acidification. Proposed contributing factors include: the emission of much additi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
