Acer Browni
''Acer browni'' is an extinct maple species in the family Sapindaceae described from a series of isolated fossil leaves and samaras. The species is known from the early to middle Miocene sediments exposed in Western Oregon, Washington state, USA and Northern Graham Island, Haida Gwaii, Canada. It is one of several extinct species placed in the living section '' Parviflora''. History and classification The eleven leaf specimens used to describe ''Acer browni'' were recovered from five different sites. The largest group of specimens was recovered from the early Miocene, Aquitanian, Collawash site exposed near the Collawash River in Clackamas County Oregon. Two additional paratype leaves were recovered from outcrops of the Latah Formation at the Vera site near Veradale, Washington. Another Washington site, on Bunker Creek west of Centralia, Washington produced one paratype leaf of middle Miocene age. The last paratype leaf is from the species' northernmost location, having been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

University Of California Museum Of Paleontology
The University of California Museum of Paleontology (UCMP) is a paleontology museum located on the campus of the University of California, Berkeley. The museum is within the Valley Life Sciences Building (VLSB), designed by George W. Kelham and completed in 1930. Its collections are primarily intended for research and are, thus, not accessible to the public. A limited number of fossils from the collection is on display in the VLSB. Although located on the Berkeley campus, the museum is the primary locality for storing fossils collected statewide. The original fossils, around which the current collection has grown, were those gathered as part of the California Geological Survey from 1860-1867. Website UCMP was one of the first museums to have its own website in the early 1990s, due to its location within a technology-oriented university with a good Internet connection. The site has been applauded for its use of visually appealing graphics, was nominated for a Webby Award five ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleobotany
Paleobotany, which is also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general. A synonym is paleophytology. It is a component of paleontology and paleobiology. The prefix ''palaeo-'' means "ancient, old", and is derived from the Greek adjective , . Paleobotany includes the study of terrestrial plant fossils, as well as the study of prehistoric marine photoautotrophs, such as photosynthetic algae, seaweeds or kelp. A closely related field is palynology, which is the study of fossilized and extant spores and pollen. Paleobotany is important in the reconstruction of ancient ecological systems and climate, known as paleoecology and paleoclimatology respectively; and is fundamental to the study of green plant developm ...

Paratype
In zoology and botany, a paratype is a specimen of an organism that helps define what the scientific name of a species and other taxon actually represents, but it is not the holotype (and in botany is also neither an isotype nor a syntype). Often there is more than one paratype. Paratypes are usually held in museum research collections. The exact meaning of the term ''paratype'' when it is used in zoology is not the same as the meaning when it is used in botany. In both cases however, this term is used in conjunction with ''holotype''. Zoology In zoological nomenclature, a paratype is officially defined as "Each specimen of a type series other than the holotype.", ''International Code of Zoological Nomenclature'' In turn, this definition relies on the definition of a "type series". A type series is the material (specimens of organisms) that was cited in the original publication of the new species or subspecies, and was not excluded from being type material by the author (th ...

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] |

Little Butte Creek (Rogue River)
Little Butte Creek is a tributary of the Rogue River in the U.S. state of Oregon. Its drainage basin consists of approximately of Jackson County and another of Klamath County. Its two forks, the North Fork and the South Fork, both begin high in the Cascade Range near Mount McLoughlin and Brown Mountain. They both flow generally west until they meet near Lake Creek. The main stem continues west, flowing through the communities of Brownsboro, Eagle Point, and White City, before finally emptying into the Rogue River about southwest of Eagle Point. Little Butte Creek's watershed was originally settled by the Takelma, and possibly the Shasta tribes of Native Americans. In the Rogue River Wars of the 1850s, most of the Native Americans were either killed or forced onto Indian reservations. Early settlers named Little Butte Creek and nearby Big Butte Creek after their proximity to Mount McLoughlin, which was known as Snowy Butte. In the late 19th century, the watershe ...
