Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago (mya). It is the first epoch of the Paleogene Period in the modern Cenozoic Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. In the Paleocene, the continents of the Northern Hemisphere were still connected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridger Formation
The Bridger Formation is a geologic formation in southwestern Wyoming. It preserves fossils dating back to the Ypresian Epoch of the Paleogene Period. The formation was named by American geologist Ferdinand Vandeveer Hayden for Fort Bridger, which had itself been named for mountain man Jim Bridger. The Bridger Wilderness covers much of the Bridger Formation's area. History Before colonization, the lands making up the Bridger Formation had been inhabited by the Apsáalooke, Bannock, Eastern Shoshone, Hinono'eino, Očhéthi Šakówiŋ, Só'taeo'o, Tsétsêhéstâhese, and Ute nations. European settlers began to settle the area around the Bridger Formation in the 19th century, beginning with the establishment of the Oregon Trail in 1830. Fort Bridger – for which the formation would later be named – was established in 1843 by Jim Bridger and Louis Vasquez. In 1868, the remaining Indigenous communities in the area were displaced by the Treaty of Fort Bridger, removing t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinopa Insectivorus
''Sinopa'' ("swift fox") is a genus of hyaenodontid mammal from family Sinopidae, that lived in North America and Asia during the early to middle Eocene. Description ''Sinopa'' was a small genus of hyaenodontid mammals. Its carnassial teeth were the second upper molar and the lower third. ''Sinopa'' species had an estimated weight of 1.33 to 13.97 kilograms. The type specimen was found in the Bridger formation in Uinta County, Wyoming, and existed 50.3 to 46.2 million years ago. Taxonomy The putative African species ''"Sinopa" ethiopica'' from Egypt was considered a species of '' Metasinopa'' by Savage (1965), although Holroyd (1994) considered it a potential new genus related to '' Quasiapterodon''.Lewis, M.

Carnivoraformes
Carnivoraformes ("carnivoran-like forms") is a clade of Placentalia, placental mammals that includes the modern order Carnivora and its extinct stem-relatives. Classification and phylogeny Classification In 2010 Flynn, Finarelli & Spaulding named a new clade Carnivoraformes within Carnivoramorpha, containing carnivorans and "Miacidae, miacids" but not Viverravidae, viverravids. The authors defined Carnivoraformes as the clade containing Carnivora and all taxa that are more closely related to Carnivora (represented by ''Wolf, Canis lupus'') than to viverravids (represented by ''Viverravus, Viverravus gracilis''). * ''Clade'': Carnivoraformes ** Order: Carnivora (carnivorans) *** Suborder: Caniformia ("dog-like" carnivorans) *** Suborder: Feliformia ("cat-like" carnivorans) ** Family: †Quercygale, Quercygalidae ** (unranked): †''Gracilocyon''/''Oodectes'' clade *** Genus: †''Eogale'' *** Genus: †''Gracilocyon''(Paraphyly, paraphyletic genus) *** Genus: †''Oodectes'' ...

Inner Mongolia
Inner Mongolia, officially the Inner Mongolia Autonomous Region, is an autonomous region of the People's Republic of China. Its border includes most of the length of China's border with the country of Mongolia. Inner Mongolia also accounts for a small section of China's border with Russia ( Zabaykalsky Krai). Its capital is Hohhot; other major cities include Baotou, Chifeng, Tongliao, and Ordos. The autonomous region was established in 1947, incorporating the areas of the former Republic of China provinces of Suiyuan, Chahar, Rehe, Liaobei, and Xing'an, along with the northern parts of Gansu and Ningxia. Its area makes it the third largest Chinese administrative subdivision, constituting approximately and 12% of China's total land area. Due to its long span from east to west, Inner Mongolia is geographically divided into eastern and western divisions. The eastern division is often included in Northeastern China (Dongbei) with major cities including Tongliao, Chifeng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevada
Nevada ( ; ) is a state in the Western region of the United States. It is bordered by Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the 7th-most extensive, the 32nd-most populous, and the 9th-least densely populated of the U.S. states.

Nevada's capital is Carson City. Las Vegas is the largest city in the state. Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State" because it achieved statehood during the Civil War (the words "Battle Born" also appear on its state flag); as the " Sagebrush State", for the native plant of the same name; and as the " Sage-hen State".

Knight Formation
A knight is a person granted an honorary title of knighthood by a head of state (including the Pope) or representative for service to the monarch, the Christian denomination, church or the country, especially in a military capacity. Knighthood finds origins in the Ancient Greece, Greek ''hippeis'' and ''hoplite'' (ἱππεῖς) and Ancient Rome, Roman ''Equites, eques'' and ''centurion'' of classical antiquity. In the Early Middle Ages in Europe, knighthood was conferred upon Equestrianism, mounted warriors. During the High Middle Ages, knighthood was considered a class of lower nobility. By the Late Middle Ages, the rank had become associated with the ideals of chivalry, a code of conduct for the perfect Court (royal), courtly Christian warrior. Often, a knight was a vassal who served as an elite fighter or a bodyguard for a lord, with payment in the form of land holdings. The lords trusted the knights, who were skilled in Horses in warfare, battle on horseback. Knighthood ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
