Osmunda Wehrii
''Osmunda wehrii'' is an extinction, extinct species of fern in the modern genus ''Osmunda'' of the family Osmundaceae. ''Osmunda wehrii'' is known from Langhian age Miocene fossils found in Central Washington (state), Washington. History and classification The species was described from specimens of Petrifaction, silicified rhizomes and frond bases in blocks of chert. The cherts were recovered from sediments outcropping near the contact of the Columbia River Basalt Group#Wanapum Basalt, Roza Basalts and the overlying Columbia River Basalt Group#Wanapum Basalt, Priest Rapids Basalts, designated the Type locality (geology), type locality, near the town of Beverly, Washington by Fred Brinkman of Sunnyside, Washington. Further specimens of ''O. wehrii'' have been found at the "Ho ho" site, one of the "county line hole" fossil localities north of Interstate 82 in Yakima County, Washington. The "Ho ho" site works strata which is part of the Museum Flow Package within the interbeds of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnolia Longiradiata
''Magnolia'' is a large genus of about 210 to 340The number of species in the genus ''Magnolia'' depends on the taxonomic view that one takes up. Recent molecular and morphological research shows that former genera ''Talauma'', ''Dugandiodendron'', ''Manglietia'', ''Michelia'', ''Elmerrillia'', ''Kmeria'', ''Parakmeria'', ''Pachylarnax'' (and a small number of monospecific genera) all belong within the same genus, ''Magnolia'' s.l. (s.l. = ''sensu lato'': 'in a broad sense', as opposed to s.s. = ''sensu stricto'': 'in a narrow sense'). The genus ''Magnolia'' s.s. contains about 120 species. See the section Nomenclature and classification in this article. flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. ''Magnolia'' is an ancient genus. Appearing before bees evolved, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arstanosaurus
''Arstanosaurus'' (meaning "Arstan lizard" after the Arstan well) is a genus of hadrosauroid dinosaur from the Santonian-Campanian-age Upper Cretaceous Bostobe Formation, Kazakhstan. It has had a confusing history, being considered both a hadrosaurid and a ceratopsid, or both at the same time ( chimeric). History The genus was based on a partial left maxilla (holotype AAIZ 1/1 or IZ AN KSSR 1/1), with the lower end of a left femur (AAIZ 1/2) possibly referable. Both were found at Akkurgan-Boltyk near Qyzylorda.Shilin, F.V., and Suslov, Y.V. (1982). A hadrosaur from the northeastern Aral Region. ''Paleontological Journal'' 1982(1):132-136 ranslated version This is not much material for naming a new genus, and it was largely ignored until the mid-1990s, when the hypothesis that it was really a ceratopsid appeared.Nesov, L.A.

Bowfin
The bowfin (''Amia calva'') is a bony fish, native to North America. Common names include mudfish, mud pike, dogfish, grindle, grinnel, swamp trout, and choupique. It is regarded as a relict, being the sole surviving species of the Halecomorphi, a group of fish that first appeared during the Early Triassic, around 250 million years ago. The bowfin is often considered a "primitive fish" because they have retained some morphological characteristics of their early ancestors. The closest living relatives of bowfins are gars, with the two groups being united in the clade Holostei. Bowfins are demersal freshwater piscivores, commonly found throughout much of the eastern United States, and in southern Ontario and Quebec. Fossil deposits indicate Amiiformes were once widespread in both freshwater and marine environments across North and South America, Europe, Asia, and Africa. Now, their range is limited to much of the eastern United States and adjacent southern Canada, including th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allenby Formation
The Allenby formation is a sedimentary rock formation in British Columbia which was deposited during the Ypresian stage of the Early Eocene. It consists of conglomerates, sandstones with interbedded shales and coal. The shales contain an abundance of insect, fish and plant fossils known from 1877 and onward, while the Princeton Chert was first indented in the 1950's and is known from anatomically preserved plants. There are several notable fossil producing localities in the Princeton & Tulameen basins. Historical collection sites included Nine Mile Creek, Vermilian Bluffs, and Whipsaw Creek, while modern sites include One Mile Creek, Pleasant Valley, Thomas Ranch, and the Princeton Chert. Extent and correlation The Allenby is estimated to have an overall extent of approximately , though actual outcroppings of the formation make up less than 1% of the formation, while other exploratory contact is via boreholes and mines. The half-graben which contains the formation is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amia Hesperia
''Amia''? ''hesperia'' is an extinct species of bony fish in the bowfin family, Amiidae. The species is known from fossils found in the early Eocene deposits of northern Washington state in the United States and southeastern British Columbia. The species is one of eight fish species identified in the Eocene Okanagan Highlands paleofauna. The species has been suggested to possibly belong to either ''Amia'' or the extinct genus '' Cyclurus''. Distribution and paleoenvironment ''Amia''? ''hesperia'' fossils have been recovered from two locations in the Eocene Okanagan Highlands, the Allenby Formation of the Princeton, British Columbia region and as isolated scales from the Klondike Mountain Formation in northern Ferry County, Washington. Both sites represent upland lake systems that were surrounded by a warm temperate ecosystem with nearby volcanism. The highlands likely had a mesic upper microthermal to lower mesothermal climate, in which winter temperatures rarely drop ...
