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 ...

Palaeoserenomyces Allenbyensis
''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 ...

Paleoflora Of The Eocene Okanagan Highlands
The paleoflora of the Eocene Okanagan Highlands includes all plant and fungi fossils preserved in the Eocene Okanagan Highlands ''Lagerstätten''. The highlands are a series of Early Eocene geological formations which span an transect of British Columbia, Canada and Washington state, United States and are known for the diverse and detailed plant fossils which represent an upland temperate ecosystem 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 1880-90s on British Columbian sites, and 1920-30s for Washington sites. A returned focus and more detailed descriptive work on the Okanagan Highlands sites revived in the 1970's. The noted richness of agricultural plant families in Republic and Princeton floras resulted in the term "Eocene orchards" being used for the paleofloras. ...

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 ...

Pleosporales
The Pleosporales is the largest order in the fungal class Dothideomycetes. By a 2008 estimate it contains 23 families, 332 genera and more than 4700 species. The majority of species are saprobes on decaying plant material in fresh water, marine, or terrestrial environments, but several species are also associated with living plants as parasites, epiphytes or endophytes. The best studied species cause plant diseases on important agricultural crops e.g. ''Cochliobolus heterostrophus'', causing southern corn leaf blight on maize, ''Phaeosphaeria nodorum'' (''Stagonospora nodorum'') causing glume blotch on wheat and ''Leptosphaeria maculans'' causing a stem canker (called blackleg) on cabbage crops (''Brassica''). Some species of Pleosporales occur on animal dung and a small number occur as lichens and rock-inhabiting fungi. Taxonomy The order was proposed in 1955 as Dothideomycetes with perithecioid ascomata with pseudoparaphyses amongst the asci, at which time there were sev ...

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 ...

Paleofauna Of The Eocene Okanagan Highlands
The paleofauna of the Eocene Okanagan Highlands is comprised of Early Eocene arthropods, vertebrates, plus rare nematodes and molluscs found in geological formations of the northwestern North American Eocene Okanagan Highlands. The highlands lake bed series' as a whole are considered one of the great Canadian ''Lagerstätten''. The paleofauna represents that of a late Ypresian upland temperate ecosystem 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 1880-90s on British Columbian sites, and 1920-30s for Washington sites. Focus and more detailed descriptive work on the Okanagan Highlands site started in the last 1970's. Most of the highlands sites are preserved as compression-impression fossils in "shales", but also includes a rare permineralized biota and an amber biota. ...

Similkameen River
The Similkameen River runs through southern British Columbia, Canada, eventually discharging into the Okanagan River near Oroville, Washington, in the United States. Through the Okanagan River, it drains to the Columbia River. The river is said to be named for an indigenous people called ''Similkameigh'', meaning "treacherous waters". The river is controversially dammed (the now-defunct Enloe Dam), blocking fish passage to the upper (Canadian) reaches of the river. History The first mention of the Similkameen by a European was by Alexander Ross. While on a trading expedition, he travelled by way of the "Similkameigh River." Sir George Simpson used the name "Similkameigh" for one of the groups part of the Okanagan Nation. The transition from ''Similkameigh'' to ''Similkameen'' may have been inspired by the name of the Tulameen River despite being etymologically incorrect. The name ''Similkameigh'' comes from a now-extinct language of Nicola-Similkameen, of the Athapascan lang ...

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 ...
