Knightia is an extinct genus of clupeid bony fish that lived in the freshwater lakes and rivers of North America and Asia during the Eocene epoch. The genus was erected by David Starr Jordan in 1907, in honor of the late University of Wyoming professor Wilbur Clinton Knight, "an indefatigable student of the paleontology of the Rocky Mountains." It is the official state fossil of Wyoming, and the most commonly excavated fossil fish in the world.
The Buthidae are the largest family of scorpions, containing about 100 genera and 1339 species as of 2022. A few very large genera are known, but a high number of species-poor or monotypic ones also exist. New taxa are being described at a rate of several new species per year. They have a cosmopolitan distribution throughout tropical and subtropical environments worldwide. Together with four other families, the Buthidae make up the superfamily Buthoidea. The family was established by Carl Ludwig Koch in 1837.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1995.
Euscorpius is a genus of scorpions, commonly called small wood-scorpions. It presently contains 65 species and is the type genus of the family Euscorpiidae – long included in the Chactidae – and the subfamily Euscorpiinae.
Archiinocellia is an extinct genus of snakefly in the family Raphidiidae known from Eocene fossils found in western North America. The genus contains two species, the older Archiinocellia oligoneura and the younger Archiinocellia protomaculata. The type species is of Ypresian age and from the Horsefly Shales of British Columbia, while the younger species from the Lutetian Green River Formation in Colorado. Archiinocellia protomaculata was first described as Agulla protomaculata, and later moved to Archiinocellia.
The taxonomy of scorpions deals with the classification of this predatory arthropod into 13 extant families and about 1,400 described species and subspecies. In addition, 111 described taxa of extinct scorpions are known.
Hottentotta is a genus of scorpions of the family Buthidae. It is distributed widely across Africa, except for most of the Sahara desert. Species in the genus also occur in the Middle East, the Arabian Peninsula, southeastern Turkey, Iraq, Iran, Afghanistan, Pakistan, India, Nepal, Cape Verde Islands, and Sri Lanka (introduced).
Pandinus is a genus of large scorpions belonging to the family Scorpionidae. It contains one of the most popular pet scorpions, the emperor scorpion . The genus is distributed across tropical Africa.
Azolla primaeva is an extinct species of "water fern" in the family Salviniaceae known from Eocene fossils from the Ypresian stage, found in southern British Columbia.
Hydriomena? protrita is an extinct species of moth in the family Geometridae, and possibly in the modern genus Hydriomena. The species is known from late Eocene, Priabonian stage, lake deposits of the Florissant Formation in Teller County, Colorado, United States. It was first described by Theodore Dru Alison Cockerell in 1922.
Denaeaspis is an extinct genus of tortoise beetle in the family Chrysomelidae and containing a single species Denaeaspis chelonopsis. The species is known only from the Middle Eocene Parachute Member, part of the Green River Formation, in the Piceance Creek Basin, Garfield County, northwestern Colorado, USA.
Eosacantha is an extinct genus of tortoise beetle in the family Chrysomelidae and containing a single species Eosacantha delocranioides. The species is known only from the Middle Eocene Parachute Member, part of the Green River Formation, in the Piceance Creek Basin, Garfield County, northwestern Colorado, USA.
Emiliana is an extinct genus of planthopper in the Tropiduchidae tribe Emilianini and containing the single species Emiliana alexandri. The species is known only from the Middle Eocene Parachute Member, part of the Green River Formation, in the Piceance Creek Basin, Garfield County, northwestern Colorado, USA.
Compsobuthus is a genus of buthid scorpions.
Priabona is an extinct genus of big-headed flies in the dipteran subfamily Nephrocerinae, within which it is one of only two genera. The genus contains a single described species, Priabona florissantius. Priabona is known from a single Late Eocene fossil from western North America.
Gyaclavator is an extinct genus of lace bug in the family Tingidae known from a fossil found in North America. The genus contains a single species, Gyaclavator kohlsi.
Neobuthus is a genus of scorpion of the family Buthidae. It is distributed across the Horn of Africa; in Eritrea, Ethiopia, Somaliland, Kenya and Djibouti.
Neobuthus factorio is a species of scorpion from the family Buthidae found in Somalia.
Orthochirus is a genus of scorpion in the family Buthidae, first described by Ferdinand Karsch in 1891.
The Green River Formation is a geological formation located in the Intermountain West of the United States, in the states of Colorado, Utah, and Wyoming. It comprises sediments deposited during the Early Eocene in a series of large freshwater lakes: Lake Gosiute, Lake Uinta, and Fossil Lake. It preserves a high diversity of freshwater fish, birds, reptiles, and mammals, with some sections of the formation qualifying as Konservat-Lagerstätten due to their extremely well-preserved fossils.
