Alaska is a U.S. state on the northwest extremity of North America. A semi-exclave of the U.S., it borders British Columbia and Yukon in Canada to the east, and it shares a western maritime border in the Bering Strait with the Russian Federation's Chukotka Autonomous Okrug. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, and the Pacific Ocean lies to the south and southwest.
Troodon is a former wastebasket taxon and a highly likely dubious genus of relatively small, bird-like theropod dinosaurs definitively known from the Campanian age of the Late Cretaceous period. It includes at least one species, Troodon formosus, known from Montana. Discovered in October 1855, T. formosus was among the first dinosaurs found in North America, although it was thought to be a lizard until 1877. Several well-known troodontid specimens from the Dinosaur Park Formation in Alberta were once believed to be members of this genus. However, recent analyses in 2017 have found this genus to be undiagnostic and referred some of these specimens to the genus Stenonychosaurus some to the genus Latenivenatrix, and some to the genus Pectinodon. The genus name is Ancient Greek for "wounding tooth", referring to the teeth, which were different from those of most other theropods known at the time of their discovery. The teeth bear prominent, apically oriented serrations. These "wounding" serrations, however, are morphometrically more similar to those of herbivorous reptiles, and suggest a possibly omnivorous diet.
The Territory of Alaska or Alaska Territory was an organized incorporated territory of the United States from August 24, 1912, until Alaska was granted statehood on January 3, 1959. The territory was previously Russian America, 1784–1867; the Department of Alaska, 1867–1884; and the District of Alaska, 1884–1912.
Pachyrhinosaurus is an extinct genus of centrosaurine ceratopsid dinosaur from the Late Cretaceous period of North America. The first examples were discovered by Charles M. Sternberg in Alberta, Canada, in 1946, and named in 1950. Over a dozen partial skulls and a large assortment of other fossils from various species have been found in Alberta and Alaska. A great number were not available for study until the 1980s, resulting in a relatively recent increase of interest in Pachyrhinosaurus.
Little Sitkin Island is a volcanic island in the Rat Islands archipelago of the Western Aleutian Islands, Alaska, about 3 miles (4.8 km) east of Davidof Island. Great Sitkin Island lies 185 miles (298 km) further east in the Andreanof Islands.
Muncho Lake Provincial Park is a provincial park in British Columbia, Canada, located on the Alaska Highway as it transits the northernmost Canadian Rockies west of Fort Nelson. The park is part of the larger Muskwa-Kechika Management Area. It is named after Muncho Lake, which is in the park and is both the name of the lake and of the community located there.
Hazy Islands Wilderness, at 32 acres, is Alaska's smallest wilderness area. It was officially designated as Wilderness in 1970 by the United States Congress. The islands are located west of Coronation Island in the Alaska Panhandle area. Hazy Islands Wilderness comprises five small islands and is home to 10 species of birds, including Brandt's cormorant (Phalacrocorax auritus). It has no anchorages or campsites, and human visitation is discouraged to protect the birds.
Bear Lake is near the town of Seward and Resurrection Bay, in the Kenai Peninsula Borough on the Kenai Peninsula in the U.S. state of Alaska. It is accessible from Bear Creek Road, which connects it to the Seward Highway. It is the site of salmon enhancement activities since 1962. This program is now managed by the Cook Inlet Aquaculture Association. Current projects at Bear Lake focus on increasing sockeye and coho salmon by controlling species that are predators and competitors.
The Prince Creek Formation is a geological formation in Alaska with strata dating to the Early Maastrichtian stage of the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
Pachyrhinosaurini is a tribe of centrosaurine dinosaurs. The clade existed during the Late Cretaceous, about 83.6 to 68.5 million years ago, evolving during the early Campanian, and becoming extinct in the Maastrichtian. The tribe contains five genera: Styracosaurus, Stellasaurus, Einiosaurus, Achelousaurus, and Pachyrhinosaurus. Pachyrhinosaurus and Achelousaurus form the clade of pachyrhinosaurins called the Pachyrostra ("thick-snouts"), characterized primarily by their nasal bosses.
Paleontology in Alaska refers to paleontological research occurring within or conducted by people from the U.S. state of Alaska. During the Late Precambrian, Alaska was covered by a shallow sea that was home to stromatolite-forming bacteria. Alaska remained submerged into the Paleozoic era and the sea came to be home to creatures including ammonites, brachiopods, and reef-forming corals. An island chain formed in the eastern part of the state. Alaska remained covered in seawater during the Triassic and Jurassic. Local wildlife included ammonites, belemnites, bony fish and ichthyosaurs. Alaska was a more terrestrial environment during the Cretaceous, with a rich flora and dinosaur fauna.
Nanuqsaurus is a genus of carnivorous tyrannosaurid theropod known from the Late Cretaceous period Prince Creek Formation of the North Slope of Alaska, United States, having lived roughly 70-68 million years ago. It contains a single species, Nanuqsaurus hoglundi, known only from a partial skull and multiple undescribed postcranial and teeth elements.
The 1974 Alaska gubernatorial election took place on November 5, 1974, for the post of Governor of Alaska. Republican challenger and mayor of Bristol Bay Borough Jay Hammond narrowly beat Democratic incumbent Bill Egan in a close race that was forced into a recount to verify the results. The formation of the new Alaskan Independence Party was considered to have a large impact on the race. Hammond had defeated former governors Wally Hickel and Keith Harvey Miller for the Republican nomination, while Egan defeated Eben Hopson and Don Wright for the Democratic nomination.
Named after Atoka County, Oklahoma, the Atoka Formation is a geologic formation in central and western Arkansas, eastern Oklahoma, central and western Texas, and eastern New Mexico. It is the surface rock of the Boston Mountains and dominates exposures in the Frontal Ouachita Mountains of the Arkansas River Valley.
The Cantwell Formation is a geologic formation in Alaska. It preserves fossils dating back to the Cretaceous period, it has also yielded numerous dinosaur tracks at Denali National Park. Contemporary therizinosaurid and hadrosaurid trackways in the formation indicate that the area was once a major point of immigration between Asia and North America during the Late Cretaceous for many families of dinosaur. Fossil plants similar to water lilies found in the same area suggest the area was a wetland or marsh, with ponds and other large standing bodies of water.
Cordylodus is an extinct genus of conodonts in the family of Cordylodontidae.
Syngenetic permafrost growth is a mode of the growth of permafrost whereby additional material is deposited to a permafrost site during freezing conditions, causing the permafrost layer to build upwards. It is cited as an efficient mode of permafrost growth, compared with heterogenetic permafrost growth, which occurs when freezing temperatures penetrate into previously unfrozen ground of uniform composition. Lunardini gives the basic formulas for permafrost generation under both modes.
Unnuakomys is an extinct metatherian mammal from the Maastrichtian age of the Late Cretaceous. It was discovered in the Prince Creek Formation of Alaska, and is the northernmost metatherian known.
The 2022 Alaska Senate elections took place on November 8, 2022, with the primary elections being held on August 16, 2022. State senators serve four-year terms in the Alaska Senate, with half of the seats normally up for election every two years. However, because most districts were greatly changed in redistricting, elections were held for 19 of the 20 seats; the only exception is District T, represented by Democrat Donny Olson, which was mostly unchanged in redistricting and thus did not have an election. Some senators were elected to serve four-year terms, while others would serve shortened two-year terms.
