Gangamopteris
''Gangamopteris'' is a genus of Carboniferous-Permian plants, very similar to ''Glossopteris''. Previously, it was classified as fern with reproduction by seed. The genus is usually only applied to leaves, making it a form taxon. ''Gangamopteris'' dominates some coal deposits, such as those of the Beacon Supergroup. In Paleorrota geopark in Rio Grande do Sul, Brazil, were found ''Gangamopteris obovata''. Were located on the Mina ''Morro do Papaléo'' in Mariana Pimentel and ''Quitéria'' in Pantano Grande. Dating from the Permian and were in the Rio Bonito Formation. In the town of Cachoeira do Sul Cachoeira do Sul () is a municipality in the state of Rio Grande do Sul, southernmost Brazil.

Glossopteridales
Glossopteridales is an extinct order (biology), order of plants belonging to Pteridospermatophyta, or seed ferns, also known as Arberiales and Ottokariales. They arose at the beginning of the Permian () on the southern continent of Gondwana, but became extinct at the end of the Permian period (), during the Permian-Triassic extinction event. The best known genus is ''Glossopteris,'' a leaf form genus. Other examples are ''Gangamopteris'' ''Glossotheca'' and ''Vertebraria''. Permian Permineralization, permineralised glossopterid reproduction organs found in the central Transantarctic Mountains suggest seeds had an wikt:adaxial, adaxial attachment to the leaf-like sporophyll, mega-sporophyll. This indicate Glossopteridales can be classified as seed ferns and is important in determining the status of the group as either close relatives or ancestors of the angiosperms. Midrib-less forms were common in the Early Permian whereas midrib forms were more common in the Lopingian, Late Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glossopteris
''Glossopteris'' tymology: from Ancient Greek γλῶσσα (glôssa, " tongue ") + πτερίς (pterís, " fern ")is the largest and best-known genus of the extinct Permian order of seed ferns known as Glossopteridales (also known as Arberiales, Ottokariales, or Dictyopteridiales). The genus ''Glossopteris'' refers only to leaves, within a framework of form genera used in paleobotany. (For likely reproductive organs see Glossopteridaceae.) Species of ''Glossopteris'' were the dominant trees of the middle- to high-latitude lowland vegetation across the supercontinent Gondwana during the Permian Period. ''Glossopteris'' fossils were critical in recognizing former connections between the various fragments of Gondwana: South America, Africa, India, Australia, New Zealand, and Antarctica. History The Glossopteridales arose in the Southern Hemisphere around the beginning of the Permian Period (), but became extinct during the end-Permian (Changhsingian) mass extinction. The putat ...

Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

Prehistoric Plant Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beacon Supergroup
The Beacon Supergroup is a geological formation exposed in Antarctica and deposited from the Devonian to the Triassic (). The unit was originally described as either a formation or sandstone, and upgraded to group and supergroup as time passed. It contains a sandy member known as the Beacon Heights Orthoquartzite. Overview The base of the Beacon Supergroup is marked by an unconformity and is composed of the Devonian Taylor Group, a quartzose sandstone sequence; and the Late Carboniferous to Early Jurassic Victoria Group, consisting of glacial beds, sandstone, shale, conglomerate, and coal. The Beacon Sandstone was named by Hartley T. Ferrar during Scott's Discovery Expedition (1901–1904), using the Beacon Heights survey points as reference. ''Glossopteris'' fossils dated the sandstone to the Permian and linked the lithology to similar sequences on neighboring continents. Generally flat lying, the supergroup is up to 3.2 km thick and is fairly continuous from south Victor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geopark
A geopark is a protected area with internationally significant geology within which sustainable development is sought and which includes tourism, conservation, education and research concerning not just geology but other relevant sciences. In 2005, a European Geopark was defined as being: "a territory with a particular geological heritage and with a sustainable territorial development....the ultimate aim of a European Geopark is to bring enhanced employment opportunities for the people who live there." Today the geopark is virtually synonymous with the UNESCO geopark, which is defined and managed under the voluntary authority of UNESCO's International Geoscience and Geoparks Programme (IGGP). UNESCO provides a standard for geoparks and a certification service to parks that apply for it. The service is available to member states of UNESCO. This list is not the same as the member states of the United Nations. Membership in the UN does not automatically imply membership in UNESCO ...
