Parastylotermes Calico
''Parastylotermes'' is an extinct genus of termite in the Isoptera family Stylotermitidae known from North America, Europe, and India. The genus contains five described species, ''Parastylotermes calico'', ''Parastylotermes frazieri'', ''Parastylotermes krishnai'', ''Parastylotermes robustus'', and ''Parastylotermes washingtonensis''. History and classification ''Parastylotermes'' was first described by entomologists Thomas E. Snyder and Alfred E. Emerson in the 1949 paper ''Catalog of the termites (Isoptera) of the world''. Prior to 1949, both ''P. washingtonensis'' and ''P. robustus'' were placed in separate modern species. Snyder and Emerson placed ''Parastylotermes'' in Stylotermitidae, which at that time was considered a subfamily, Stylotermitinae, of the family Rhinotermitidae. Species ''P. robustus'' ''P. robustus'' was the first species to be described, having been published by Baron Kurt von Rosen as ''Leucotermes robustus'' in 1913. Fossils of the species were reco ...

Ypresian
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the lower Eocene. Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. Stratigraphic definition The Ypresian Stage was introduced in scientific literature by Belgium, Belgian geologist André Hubert Dumont in 1850. The Ypresian is named after the Flanders, Flemish city of Ypres in Belgium (spelled ''Ieper'' in Dutch). The definitions of the original stage were totally different from the modern ones.

Latah Formation
The Latah Formation is a series of late Miocene lacustrine sedimentary deposits which outcrop in eastern Washington and northwestern Idaho. The lake beds are interbedded with igneous rock of the Columbia River Basalt Group. The formation was originally detailed from a site in Spokane, Washington by Dr. Kirk Bryan in a 1923 talk, and then formally described in a 1926 journal article by Joseph Pardee and Bryan. When first described the formation was thought to have predated the deposition of the Columbia River Basalts, however further investigation showed them to be interbedded, being laid down in successive events. Potassium-argon dating of the formation returned an age range of 21.3 to 12.1 million years old, indicating an Early to Middle Miocene age range. Numerous fossil plants and insects have been recovered from the formation and described. The Latah Formation includes the Clarkia fossil beds The Clarkia fossil beds (also known locally as the Fossil Bowl) is a Miocene ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inclusion (mineral)
In mineralogy, an inclusion is any material that is trapped inside a mineral during its formation. In gemology, an inclusion is a characteristic enclosed within a gemstone, or reaching its surface from the interior. According to Hutton's law of inclusions, fragments included in a host rock are older than the host rock itself. Mineralogy Inclusions are usually other minerals or rocks, but may also be water, gas or petroleum. Liquid or vapor inclusions are known as fluid inclusions. In the case of amber it is possible to find insects and plants as inclusions. The analysis of atmospheric gas bubbles as inclusions in ice cores is an important tool in the study of climate change. A xenolith is a pre-existing rock which has been picked up by a lava flow. Melt inclusions form when bits of melt become trapped inside crystals as they form in the melt. Gemology Inclusions are one of the most important factors when it comes to gem valuation. In many gemstones, such as diamonds, i ...
