Uhlia
''Uhlia'' is an extinct genus of coryphoid palm containing a single species ''Uhlia allenbyensis''. The species is known from permineralized remains recovered from the Princeton Chert in British Columbia, Canada. Leaves of ''Uhlia'' have "tar spot"-like fungal infections of the extinct ascomycete '' Paleoserenomyces'', which in turn are hyperparasitized by the ascomycete '' Cryptodidymosphaerites''. Distribution ''Uhlia allenbyensis'' is known exclusively from the Princeton Chert, a fossil locality in British Columbia, Canada, which comprises an anatomically preserved flora of Eocene Epoch age, with rich species abundance and diversity. The chert is located in exposures of the Allenby Formation on the east bank of the Similkameen River, south of the town of Princeton, British Columbia. Notable in conjunction with the coal seams of the Allenby Formation are sections of chert which formed during silica-rich periods. The rapid cyclical changes from coal to chert and back ...

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] |
Cryptodidymosphaerites
''Cryptodidymosphaerites'' is an extinct monotypic genus of pleosporale fungus of uncertain family placement. When described it contained the single species ''Cryptodidymosphaerites princetonensis''. The genus is solely known from the Early Eocene, Ypresian aged, Princeton Chert deposit of the Allenby Formation. ''Cryptodidymosphaerites'' is one of only three described fossil fungus species found in the Princeton Chert, and is a hyperparasite of '' Palaeoserenomyces allenbyensis'', itself a tar spot-like parasite of the fossil palm ''Uhlia''. Distribution ''Cryptodidymosphaerites princetonensis'' is known exclusively from the Princeton Chert, a fossil locality in British Columbia, Canada, which comprises an anatomically preserved flora of Eocene Epoch age, with rich species abundance and diversity. The chert is located in exposures of the Allenby Formation on the east bank of the Similkameen River, south of the town of Princeton, British Columbia. Notable in conju ...

Paleoserenomyces
''Paleoserenomyces'' is an extinct monotypic genus of pleosporale fungus of uncertain family placement. When described it contained the single species ''Paleoserenomyces allenbyensis''. The genus is solely known from the Early Eocene, Ypresian aged, Princeton Chert deposit of the Allenby Formation. ''Palaeoserenomyces'' is one of only three described fossil fungus species found in the Princeton Chert, being a tar spot like parasite of the fossil palm '' Uhlia allenbyensis'', and is host for the hyperparasite ''Cryptodidymosphaerites princetonensis''. History and classification The type series of fossils were first identified in serial thin section cellulose acetate peels of '' Uhlia allenbyensis'' fossils. The peels were made with hydrofluoric acid and mounted in Eukitt mounting material, than affixed to microscope slides using double sided tape. The holotype and paratype microscope slides were accessioned into the University of Alberta palaeobotanical collections and the form ...

Coryphoideae
The Coryphoideae is one of five subfamilies in the palm family, Arecaceae. It contains all of the genera with palmate leaves, excepting ''Mauritia'', ''Mauritiella'' and ''Lepidocaryum,'' all of subfamily Calamoideae, tribe Lepidocaryeae, subtribe Mauritiinae. However, all Coryphoid palm leaves have induplicate (V-shaped) leaf folds (excepting ''Guihaia''), while Calamoid palms have reduplicate (inverted V-shaped) leaf folds. Pinnate leaves do occur in Coryphoideae, in ''Phoenix'', '' Arenga'', ''Wallichia'' and bipinnate in ''Caryota''. Classification Subfamily Coryphoideae is divided into 8 tribes: * Sabaleae ** ''Sabal'' * Cryosophileae ** ''Schippia'' ** '' Trithrinax'' ** ''Zombia'' ** ''Coccothrinax'' ** ''Hemithrinax'' ** ''Thrinax'' ** ''Chelyocarpus'' ** ''Cryosophila'' ** ''Itaya'' ** ''Sabinaria'' * Phoeniceae ** ''Phoenix'' * Trachycarpeae ** ''Chamaerops'' ** ''Guihaia'' ** ''Trachycarpus'' ** ''Rhapidophyllum'' ** ''Maxburretia'' ** ''Rhapis'' ** ''Livistona'' ...

Klondike Mountain Formation
The Klondike Mountain Formation is an Early Eocene (Ypresian) geological formation located in the northeast central area of Washington state. The formation, named for the type location designated in 1962, Klondike Mountain north of Republic, Washington, is composed of volcanic rocks in the upper unit and volcanics plus lacustrine (lakebed) sedimentation in which a lagerstätte with exceptionally well-preserved plant and insect fossils has been found, along with fossil epithermal hot springs. The formation is the youngest in a group of formations which belong to the Challis Sequence rocks. The formation unconformably overlies rocks of the Eocene Sanpoil Volcanics and much older Triassic and Permian formations. The formation is bounded on its edges by a series of high-angle strike slip faults, which have contained the Klondike Mountain Formation in a series of graben structures, such as the Republic Graben. Public access to a fossiliferous outcrop at the north end of Republic is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Princeton Chert
The Princeton Chert is a fossil locality in British Columbia, Canada, which comprises an anatomically preserved flora of Eocene Epoch age, with rich species abundance and diversity. It is located in exposures of the Allenby Formation on the east bank of the Similkameen River, south of the town of Princeton, British Columbia. History The Princeton Chert (Ashnola shale in older sources) and its fossils have been known since the 1950s, but have attracted increased attention in the late 1970 and on. This may be due to the rare type of silica permineralized fossil Lagerstätten found, which has preserved plants and animals in minute 3D detail, with exceptional internal cellular detail. This has meant anatomical descriptions and reconstruction of whole plants from isolated parts has been possible in many species. Few plant fossils elsewhere in the world exhibit such excellence in both preservation and diversity. Similar aged fossil beds in Eocene lake sediments are found elsewhere in ...

Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a precipitation (chemistry), chemical precipitate or a diagenesis, diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color (from white to black), but most often manifests as gray, brown, grayish brown and light green to rusty redW.L.

Eocene Okanagan Highlands
The Eocene Okanagan Highlands or Eocene Okanogan Highlands are a series of Early Eocene geological formations which span a transect of British Columbia, Canada, and Washington state, United States. Known for a highly diverse and detailed Paleoflora of the Eocene Okanagan Highlands, plant and Paleofauna of the Eocene Okanagan Highlands, animal Biome, paleobiota the paleolake beds as a whole are considered one of the great Canadian ''Lagerstätten''. The paleobiota represented are of an upland subtropical to temperate ecosystem series immediately after the Paleocene–Eocene thermal maximum, and before the increased cooling of the middle and late Eocene to Oligocene. The fossiliferous deposits of the region were noted as early as 1873, with small amounts of systematic work happening in the 1870–1920s on British Columbian sites, and 1920–1930s for Washington sites. Focus and more detailed descriptive work on the Okanagan Highland sites started in the late 1960s. Extent The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ferry County, Washington
Ferry County is a county located on the northern border of the U.S. state of Washington. As of the 2020 census, the population was 7,178, making it the fourth-least populous county in Washington. The county seat and largest city is Republic. The county was created out of Stevens County in February 1899 and is named for Elisha P. Ferry, the state's first governor. History During the time of Washington Territory, the Territorial Legislature created Stevens County in 1863, containing all the land from the Columbia River to the Cascades north of the Wenatchee River from Walla Walla County. On January 20, 1864, the original Spokane County was dissolved and merged with the unorganized Stevens County. The western section of Stevens County was separated on February 18, 1899, and named Ferry County, in recognition of the Territory's last governor and the State's first governor, Elisha P. Ferry. The town of Republic is the county's seat of government, as well as the largest town. It wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
