Wyseotrypa is an extinct Permian genus of bryozoans of the family Hyphasmoporidae. It was discovered in northeastern Nevada. [1]
The Permian is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period 298.9 million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia.
Approximately 251.9 million years ago, the Permian–Triassicextinction event forms the boundary between the Permian and Triassic geologic periods, and with them the Paleozoic and Mesozoic eras. It is the Earth's most severe known extinction event, with the extinction of 57% of biological families, 83% of genera, 81% of marine species and 70% of terrestrial vertebrate species. It is also the largest known mass extinction of insects. It is the largest of the "Big Five" mass extinctions of the Phanerozoic. There is evidence for one to three distinct pulses, or phases, of extinction.
Battle Mountain is an unincorporated town in and the county seat of Lander County, Nevada, United States. The population was 3,705 at the 2020 census. Its primary economic base is gold mining and, to a lesser extent, legalized gambling.
The Black Rock Desert is a semi-arid region of lava beds and playa, or alkali flats, situated in the Black Rock Desert–High Rock Canyon Emigrant Trails National Conservation Area, a silt playa 100 miles (160 km) north of Reno, Nevada that encompasses more than 300,000 acres (120,000 ha) of land and contains more than 120 miles (200 km) of historic trails. It is in the northern Nevada section of the Great Basin with a lakebed that is a dry remnant of Pleistocene Lake Lahontan.
El Paso Natural Gas (EPNG) is an American company with a system of natural gas pipelines that brings gas from the Permian Basin in Texas and the San Juan Basin in New Mexico and Colorado to West Texas, New Mexico, Nevada, California, and Arizona. It also exports some natural gas to Mexico.
The Kaibab Limestone is a resistant cliff-forming, Permian geologic formation that crops out across the U.S. states of northern Arizona, southern Utah, east central Nevada and southeast California. It is also known as the Kaibab Formation in Arizona, Nevada, and Utah. The Kaibab Limestone forms the rim of the Grand Canyon. In the Big Maria Mountains, California, the Kaibab Limestone is highly metamorphosed and known as the Kaibab Marble.
The Eureka & Palisade Railroad was a 3 ft narrow gauge railroad constructed in 1873-1875 between Palisade and Eureka, Nevada, a distance of approximately 85 miles (137 km). The railroad was constructed to connect Eureka, the center of a rich silver mining area, with the national railway network at Palisade.
Prionosuchus is an extinct genus of large temnospondyl. A single species P. plummeri, is recognized from the Early Permian. Its fossils have been found in what is now northeastern Brazil.
Kamacops is a genus of dissorophid temnospondyls known from the Middle to Late Permian of Russia that was described by Yuri Gubin in 1980. It is known from a single species, Kamacops acervalis, material of which is currently reposited in the Paleontological Institute of the Russian Academy of Sciences. Kamacops is one of the youngest dissorophids, along with Iratusaurus and Zygosaurus from Russia and Anakamacops from China and was one of the largest known dissorophids, with an estimated skull length of 24–30 cm. It is typically recovered as being most closely related to Zygosaurus and to the North American Cacops. A detailed study of the braincase region was performed by Schoch (1999), one of the first to examine this region in dissorophids. This study revealed extensive co-ossification of the braincase.
The Sonoma orogeny was a period of mountain building in western North America. The exact age and structure of the Sonoma orogeny is controversial. The orogeny is generally thought to have occurred during the Permian / Triassic transition, around 250 million years ago, following the Late Devonian Antler orogeny. The Sonoma orogeny was one of a sequence of accretionary events along the Cordilleran margin, possibly caused by the closure of the basin between the island arc of Sonomia and the North American continent. Evidence of this event has been reported throughout western North America, but most distinctly in northwest Nevada.
Apateon is an extinct genus of temnospondyl amphibian within the family Branchiosauridae.
Broiliellus is an extinct genus of dissorophoid temnospondyl within the family Dissorophidae. Broiliellus is most closely related to the genus Dissorophus, and both have been placed in the subfamily Dissorophinae. Broiliellus is known from five species from the Early Permian: the type species is Broiliellus texensis, and the other species are Broiliellus brevis,Broiliellus olsoni, Broiliellus arroyoensis, and Broiliellus reiszi. An additional species, Broiliellus novomexicanus, which was originally named Aspidosaurus novomexicanus, is now thought to fall outside the genus as a member of the subfamily Eucacopinae.
Olsoniformes is a clade of dissorophoid temnospondyls, including the families Dissorophidae and Trematopidae. Most members of the clade were highly adapted to a terrestrial lifestyle. The clade was named in 2008 and is defined as the least inclusive clade containing Dissorophus multicinctus and Acheloma cumminsi but not Amphibamus grandiceps, Micromelerpeton credneri, or Apateon pedestris. Olsoniforms share various features such as a stout and low ilium and a thin cultriform process. The earliest-branching olsoniform is Palodromeus bairdi, from the Late Carboniferous of Ohio.
Synechodontiformes is an extinct order of prehistoric shark-like cartilaginous fish, known from the Permian to the Paleogene. They are considered to be members of Neoselachii, the group that contains modern sharks and rays.
Amphibamiformes is an unranked clade with Dissorophoidea created by Schoch (2018). It encompasses all of the taxa traditionally considered to be "amphibamids", branchiosaurids, and hypothetically lissamphibians under the traditional temnospondyl hypothesis of lissamphibian origins. These taxa are typically small-bodied dissorophoids and form the sister group to Olsoniformes, which comprises dissorophids and trematopids.
The 1999 Nevada Wolf Pack football team represented the University of Nevada, Reno during the 1999 NCAA Division I-A football season. Nevada competed as a member of the Big West Conference (BWC). The Wolf Pack were led by fourth–year head coach Jeff Tisdel, who resigned after the end of the season. They played their home games at Mackay Stadium.
Crurithyris is an extinct genus of brachiopod belonging to the order Spiriferida and family Ambocoeliidae.
Utgaardostylus is an extinct Permian bryozoan genus of the family Dyscritellidae. It was discovered in northeastern Nevada.
Neoeridotrypella is an extinct genus of bryozoan of the family Eridotrypellidae, known from the Permian period. Its colonies were typically branching or tree-shaped though sometimes encrusting or massive, and the walls of its zooecial chambers were thicker within the exozone and full of tiny tubules.
Stenodiscus is an extinct genus of bryozoan of the family Stenoporidae, known from the Carboniferous to the Upper Permian periods. Its colonies were large and could be encrusting, massive, or branching, sometimes made of multiple layers of growth over themselves, and usually possessed monticules with abundant large acanthostyles.
