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 The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic system which spans 47 million years, from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya.

Glossopteridales
Glossopteridales is an extinct order of seed plants, known from the Permian of Gondwana. They arose at the beginning of the Permian, and the majority or all members of the group became extinct at the end of the Permian (251.9 mya), during the Permian-Triassic extinction event. Possible Triassic records of the group have been recorded. The best known genus is '' Glossopteris,'' a leaf form genus. Other examples are '' Gangamopteris,'' '' Glossotheca,'' and '' Vertebraria''. Permian permineralised glossopterid reproduction organs found in the central Transantarctic Mountains suggest seeds had an adaxial attachment to the leaf-like 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 Late Permian Late or LATE may refer to: Everyday usage * T ...

Glossopteris
''Glossopteris'' (etymology: from Ancient Greek γλῶσσα (glôssa, " tongue ") + πτερίς (pterís, " fern ")) is the largest and best-known genus of the extinct Permian order of seed plants known as Glossopteridales (also known as Arberiales, Ottokariales, or Dictyopteridiales). The name ''Glossopteris'' refers only to leaves, within the framework of form genera used in paleobotany, used for leaves of plants belonging to the glossopterid family Dictyopteridiaceae. Species of ''Glossopteris'' were the dominant trees of the middle to high-latitude lowland vegetation, often in swampy environments, across Gondwana (which at this time formed the southern part of Pangaea) 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. The ''Glossopteris'' forest ecosystems became extinct as part of the end-Permian mass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous
The Carboniferous ( ) is a Geologic time scale, geologic period and System (stratigraphy), system of the Paleozoic era (geology), era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon (geology), eon. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian (geology), Mississippian and the later Pennsylvanian (geology), Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("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 (geologist), William Conybeare and William Phillips (geologist), William Phillips in 1822, based on a study of the British rock succession.

Prehistoric Plant Genera
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins 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 years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Rio Bonito Formation is a geological formation of the Paraná and Pelotas Basins of Permian age.

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] |
