Noeggerathia
''Noeggerathia'' is an extinct genus of noeggerathialean plant that lived during the Late Carboniferous and Early Permian periods. Description ''Noeggerathia'' could grow to be 3 ft, 3 in tall. It is known for its compound leaves, each possessing two rows of leaflets which composed a 12-inch frond. ''Noeggerathia'' may also have possessed a short trunk. The genus may have possessed strobili at the ends of its branches for reproductive purposes. Biseriate sporophylls existed on either side of the cones. It has been previously suggested that ''Noeggerathiostrobus'' may have been borne at the end of ''Noeggerathias stems, although it is more likely that ''Noeggerathiostrobus'' was borne closer to the base of ''Noeggerathia''. Taxonomy ''Noeggerathia'' was named after Johann Jakob Nöggerath, a geologist from Germany. The genus was described in 1820 by Kaspar Maria von Sternberg. ''Noeggerathia'' and noeggerathialeans in general have been described as difficult to classi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Noeggerathiales
Noeggerathiales is a now-extinct order of vascular plants. The fossil range of the order extends from the Upper Carboniferous to the upper Permian (Lopingian). Due to gaps in the fossil record, the group is incompletely known and poorly defined, and their taxonomic status and position in the plant kingdom are uncertain. The Noeggerathiales have been proposed in the evolutionary scheme in two remotely related groups of vascular plants, the Pteropsida and the Sphenopsida. Noeggerathiales have been previously linked to horsetails and ferns, but are currently believed to be progymnosperms. Noeggerathiales had a tree fern The tree ferns are arborescent (tree-like) ferns that grow with a trunk elevating the fronds above ground level, making them trees. Many extant tree ferns are members of the order Cyatheales, to which belong the families Cyatheaceae (scaly tree ... like appearance, with leaves sprouting from the top of an unbranched trunk.

Progymnospermopsida
The progymnosperms are an extinct group of woody, spore-bearing plants that is presumed to have evolved from the trimerophytes, and eventually gave rise to the gymnosperms, ancestral to acrogymnosperms and angiosperms (flowering plants). They have been treated formally at the rank of division Progymnospermophyta or class Progymnospermopsida (as opposite). The stratigraphically oldest known examples belong to the Middle Devonian order the Aneurophytales, with forms such as '' Protopteridium'', in which the vegetative organs consisted of relatively loose clusters of axes. ''Tetraxylopteris'' is another example of a genus lacking leaves. In more advanced aneurophytaleans such as ''Aneurophyton'' these vegetative organs started to look rather more like fronds, and eventually during Late Devonian times the aneurophytaleans are presumed to have given rise to the pteridosperm order, the Lyginopteridales. In Late Devonian times, another group of progymnosperms gave rise to the first re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permian
The Permian ( ) is a geologic period and 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 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Jakob Nöggerath
Johann Jakob Nöggerath (also as Johann Jacob Noeggerath) (10 October 1788 – 13 September 1877), German mineralogist and geologist, was born at Bonn. In 1814-1815 he became a commissioner of mines for some of the Rhine provinces, and in 1818 became an associate professor at the newly established University of Bonn. In 1821 he was named a full professor of mineralogy and mining sciences at Bonn, where he also served as director of the university's natural history museum. He obtained a very fine collection of minerals for the museum, was eminently successful as a teacher, and achieved a wide reputation among mining engineers. The following are his more important publications: * ''Über aufrecht im Gebirgsgestein eingeschlossene fossile Baumstämme und andere Vegetabilien'' (1819-1821). * ''Das Gebirge in Rheinland-Westphalen, nach mineralogischem und chemischem Bezuge'' (4 volumes, 1822-1826). * ''Die Entstehung und Ausbildung der Erde, vorzüglich durch Beispiele aus Rheinl ...

William Carruthers (botanist)
William C Carruthers (29 May 1830 – 2 June 1922) was a Scottish botanist and paleobotanist. Life Carruthers was the keeper of the Botanical Department at the Natural History Museum, London, Natural History Museum from 1871 to 1895. He was a consulting botanist to the Royal Agricultural Society of England, Royal Agricultural Society (1871–1909). He was born in Moffat, Dumfriesshire, the son of merchant Samuel Carruthers. Educated at Moffat Academy, he graduated from the University of Edinburgh. As a student he supported himself by working as a tutor. In 1854 he began to study for the Presbyterian Ministry at New College, Edinburgh, but then decided to specialise in natural sciences. He became a lecturer in Botany at the New Veterinary College in Edinburgh, and served as assistant secretary to the Royal Society of Edinburgh. He became assistant in the botany department of the British Museum in 1859, becoming Keeper of Botany in 1871 and retiring in 1895. He oversaw the transfe ...

Ottokar Feistmantel
Otokar Eduard Franz Karel Feistmantel (other spellings include Otakar Feistmantl) (20 November 1848 in Stará Huť – 10 February 1891 in Prague) was a Czech-Austrian (born in Bohemia) geologist and paleontologist who studied in Prague and Berlin and worked with the Geological Survey of India in India where he replaced Ferdinand Stoliczka who died of altitude sickness on an expedition in 1874. Feistmantel described several genera and species of fossil plants from peninsular India and his work on the "Gondwana Series" contributed to the development of the idea of the ancient supercontinent of Gondwanaland. Early life Otokar was the second son of Karl (or Karel) Feistmantel (1819–1885), an expert on mines who later took an interest in geology and palaeontology and Františka, née Nechvátalová. Although most records note that he was born on 20 November 1848 in Stará Huť (today a part of Hýskov) near Beroun, he recorded it as 21 November in an unpublished autobiographical note ...

Strobilus
A strobilus (plural: strobili) is a structure present on many land plant species consisting of sporangia-bearing structures densely aggregated along a stem. Strobili are often called cones, but some botanists restrict the use of the term cone to the woody seed strobili of conifers. Strobili are characterized by a central axis (anatomically a stem) surrounded by spirally arranged or decussate structures that may be modified leaves or modified stems. Leaves that bear sporangia are called ''sporophylls'', while sporangia-bearing stems are called '' sporangiophores''. Lycophytes Some members of both of the two modern classes of Lycopodiophyta (Lycopodiopsida and Isoetopsida) produce strobili. In all cases, the lateral organs of the strobilus are microphylls, bearing sporangia. In other lycophytes, ordinary foliage leaves can act as sporophylls, and there are no organized strobili.
