Context: Saurolophus (meaning "lizard crest") is a genus of large saurolophine hadrosaurid dinosaurs that lived about 70.068.5 million years ago, in the Late Cretaceous of North America and Asia; it is one of the few genera of dinosaurs known from multiple continents. It is distinguished by a spike-like crest which projects up and back from the skull. "Saurolophus" was a herbivorous dinosaur which could move about either bipedally or quadrupedally., Alberta is a western province of Canada. With an estimated population of 4,196,457 as of July 1, 2015, it is Canada's fourth-most populous province and the most populous of Canada's three prairie provinces. Its area is about . Alberta and its neighbour Saskatchewan were districts of the Northwest Territories until they were established as provinces on September 1, 1905. The premier has been Rachel Notley since May 2015., Ornithopods or members of the clade Ornithopoda (or ) are a group of ornithischian dinosaurs that started out as small, bipedal running grazers, and grew in size and numbers until they became one of the most successful groups of herbivores in the Cretaceous world, and dominated the North American landscape. Their major evolutionary advantage was the progressive development of a chewing apparatus that became the most sophisticated ever developed by a non-avian dinosaur, rivaling that of modern mammals such as the domestic cow. They reached their apex in the duck-bills (hadrosaurs), before they were wiped out by the CretaceousPaleogene extinction event along with all other non-avian dinosaurs. Members are known from all seven continents, though they are generally rare in the Southern Hemisphere., Idaho is a state in the northwestern region of the United States. It borders the state of Montana to the east and northeast, Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. To the north, it shares a small portion of the Canadian border with the province of British Columbia. With a population of around 1.7 million people and an area of , Idaho is the 14th largest and 39th most populous of the 50 states. The state's capital and largest city is Boise., Saskatchewan (or ) is a prairie and boreal province in west-central Canada, the only province without natural borders. It has an area of , nearly 10 percent of which is fresh water, composed mostly of rivers, reservoirs, and the province's 100,000 lakes., The Jurassic (from Jura Mountains) is a geologic period and system that spans 56.3 million years from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period Mya. The Jurassic constitutes the middle period of the Mesozoic Era, also known as the Age of Reptiles. The start of the period is marked by the major TriassicJurassic extinction event. Two other extinction events occurred during the period: the Pliensbachian/Toarcian event in the Early Jurassic, and the Tithonian event at the end; however, neither event ranks among the "Big Five" mass extinctions., The skull is a bony structure that forms the head of the skeleton in most vertebrates. It supports the structures of the face and provides a protective cavity for the brain. The skull is composed of two parts: the cranium and the mandible. In the human these two parts are the neurocranium and the viscerocranium or facial skeleton that includes the mandible as its largest bone. The skull forms the anterior most portion of the skeleton and is a product of cephalisationhousing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In the human these sensory structures are part of the facial skeleton., Edmontosaurus is a genus of hadrosaurid (duck-billed) dinosaur. It contains two known species: "Edmontosaurus regalis" and "Edmontosaurus annectens". Fossils of "E. regalis" have been found in rocks of western North America that date from the late Campanian stage of the Cretaceous Period 73 million years ago, while those of "E. annectens" were found in the same geographic region but in rocks dated to the end of the Maastrichtian stage of the Cretaceous, 66 million years ago. "Edmontosaurus" was one of the last non-avian dinosaurs, and lived alongside dinosaurs like "Triceratops" and "Tyrannosaurus" shortly before the CretaceousPaleogene extinction event., Dinosaurs are a diverse group of animals of the clade Dinosauria that first appeared during the Triassic. Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, the current scientific consensus places their origin between 231 and 243 million years ago. They became the dominant terrestrial vertebrates after the TriassicJurassic extinction event 201 million years ago. Their dominance continued through the Jurassic and Cretaceous periods and ended when the CretaceousPaleogene extinction event led to the extinction of most dinosaur groups 66 million years ago., Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara., Iguanodontia is a clade of herbivorous dinosaurs that lived from the Middle Jurassic to Late Cretaceous. Some members include "Camptosaurus", "Callovosaurus", "Iguanodon", "Tenontosaurus", and the hadrosaurids or "duck-billed dinosaurs". Iguanodontians were one of the first groups of dinosaurs to be found. They are among the best known of the dinosaurs, and were among the most diverse and widespread herbivorous dinosaur groups of the Cretaceous period. Derived iguanodontians (such as "Muttaburrasaurus" and many ankylopollexians) were generally large animals, and some (such as "Shantungosaurus", which measured up to 50 ft (15 m) in length and weighed up to 8 tons) equaled the largest carnivorous dinosaurs in size., Canada (French: ) is a country in the northern half of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering , making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. The majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains. About four-fifths of the country's population of 36 million people is urbanized and live near the southern border. Its capital is Ottawa, its largest city is Toronto; other major urban areas include Montreal, Vancouver, Calgary, Edmonton, Quebec City, Winnipeg and Hamilton., Saurolophini is a tribe of saurolophine hadrosaurid native to North America and Asia . It includes Saurolophus ( from Canada and Mongolia ) , Augustynolophus ( from U.S. ) , and Prosaurolophus ( from Alberta , Canada , and Montana , U.S. ) . Kerberosaurus and Kundurosaurus may also be members . Fossils of saurolophins have been found in Canada , USA , and Asia , with the North American fossils being older than the Asian , suggesting saurolophins migrated intra-continentally ., Wyoming is a state in the mountain region of the western United States. The state is the tenth largest by area, the least populous and the second least densely populated state in the country. Wyoming is bordered on the north by Montana, on the east by South Dakota and Nebraska, on the south by Colorado, on the southwest by Utah, and on the west by Idaho. Cheyenne is the capital and the most populous city in Wyoming, with a population estimate of 63,335 in 2015. The state population was estimated at 586,107 in 2015, which is less than the population of 31 of the largest U.S. cities., Parasaurolophus (or ; meaning "near crested lizard" in reference to "Saurolophus") is a genus of ornithopod dinosaur that lived in what is now North America during the Late Cretaceous Period, about 76.574.5 million years ago. It was a herbivore that walked both as a biped and a quadruped. Three species are recognized: "P. walkeri" (the type species), "P. tubicen", and the short-crested "P. cyrtocristatus". Remains are known from Alberta (Canada), and New Mexico and Utah (United States). The genus was first described in 1922 by William Parks from a skull and partial skeleton found in Alberta., Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, southern Brazil and Uruguay as well as the steppes of Eurasia.
Lands typically referred to as "prairie" tend to be in North America. The term encompasses the area referred to as the Interior Lowlands of Canada, the United States, and Mexico, which includes all of the Great Plains as well as the wetter, somewhat hillier land to the east. In the U.S., the area is constituted by most or all of the states of North Dakota, South Dakota, Nebraska, Kansas, and Oklahoma, and sizable parts of the states of Montana, Wyoming, Colorado, New Mexico, Texas, Missouri, Iowa, Illinois, Ohio, Indiana, Wisconsin, and western and southern Minnesota. The Central Valley of California is also a prairie. The Canadian Prairies occupy vast areas of Manitoba, Saskatchewan, and Alberta., The Dinosaur Park Formation is the uppermost member of the Belly River Group (also known as the Judith River Group), a major geologic unit in southern Alberta. It was laid down during the Campanian stage of the Late Cretaceous epoch between 76.6 and 74.8 million years ago. It was deposited in alluvial and coastal plain environments, and it is bounded by the nonmarine Oldman Formation below it and the marine Bearpaw Formation above it., Lambeosaurinae is a group of crested hadrosaurid dinosaurs. Classification. Lambeosaurines have been traditionally split into the tribes or clades Parasaurolophini ("Parasaurolophus", "Charonosaurus", others (?).) and Lambeosaurini ("Corythosaurus", "Hypacrosaurus", "Lambeosaurus", others.). Corythosaurini (sinonym of Lambeosaurini, see below) and Parasaurolophini as terms entered the formal literature in Evans and Reisz's 2007 redescription of "Lambeosaurus magnicristatus". Corythosaurini was defined as all taxa more closely related to "Corythosaurus casuarius" than to "Parasaurolophus walkeri", and Parasaurolophini as all those taxa closer to "P. walkeri" than to "C. casuarius". In this study, "Charonosaurus" and "Parasaurolophus" are parasaurolophins, and "Corythosaurus", "Hypacrosaurus", "Lambeosaurus", "Nipponosaurus", and "Olorotitan" are corythosaurins. However, later researchers pointed out that due to the rules of priority set forth by the ICZN, Any tribe containing "Lambeosaurus" is properly named Lambeosaurini, and that therefore the name "Corythosaurini" is a junior synonym, and the definition had "Corythosaurus casuarius" changed to "Lambeosaurus lambei", and the same for Parasaurolophini. In more recent years Tsintaosaurini ("Tsintaosaurus" + "Pararhabdodon") and Aralosaurini ("Aralosaurus" + "Canardia") have also emerged., The Northwest Territories (also known as NWT; French: "les Territoires du Nord-Ouest", "TNO"; Athabaskan languages: "Denendeh"; Inuinnaqtun: "Nunatsiaq"; Inuktitut: ) is a territory of Canada. At a land area of approximately and a 2011 population of 41,462, it is the second largest and most populous of the three territories in Northern Canada. Its estimated population as of 2016 is 44,291. Yellowknife became the territorial capital in 1967, following recommendations by the Carrothers Commission., The Cretaceous is a geologic period and system that spans 79 million years from the end of the Jurassic Period million years ago (Mya) to the beginning of the Paleogene Period Mya. It is the last period of the Mesozoic Era. The Cretaceous Period is usually abbreviated K, for its German translation "Kreide" (chalk)., Hadrosaurids ("hadrós", "stout, thick"), or duck-billed dinosaurs, are members of the ornithischian family Hadrosauridae. This group is also known as the duck-billed dinosaurs, for the flat, duck-bill appearance of their mouths. The family, which includes ornithopods such as "Edmontosaurus" and "Parasaurolophus", was a common herbivore in the Upper Cretaceous Period of what is now Asia, Europe, Antarctica, South America and North America. Hadrosaurids are descendants of the Upper Jurassic/Lower Cretaceous iguanodontian dinosaurs and had a similar body layout.
Like the rest of the ornithischians, these animals had a predentary bone and a pubic bone which was positioned backwards in the pelvis. Hadrosaurids are divided into two principal subfamilies: the lambeosaurines ("Lambeosaurinae"), which had hollow cranial crests or tubes, and the saurolophines, identified as hadrosaurines in most pre-2010 works ("Saurolophinae" or" Hadrosaurinae"), which lacked hollow cranial crests (solid crests were present in some forms). Saurolophines tended to be bulkier than lambeosaurines. Lambeosaurines are divided into Aralosaurines, Lambeosaurines, Parasaurolophines and Tsintaosaurines, while Saurolophines include Saurolophus, Brachylophosaurines and Kritosaurines., Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people., A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material., Saurolophinae is a subfamily of hadrosaurid dinosaurs. It has since the mid-20th century generally been called the Hadrosaurinae, a group of largely non-crested hadrosaurs related to the crested sub-family Lambeosaurinae. However, the name Hadrosaurinae is based on the genus "Hadrosaurus" which was found in more recent studies to be more primitive than either lambeosaurines or other traditional "hadrosaurines", like "Edmontosaurus" and "Saurolophus". As a result of this, the name Hadrosaurinae was dropped or restricted to "Hadrosaurus" alone, and the subfamily comprising the traditional "hadrosaurines" was renamed the Saurolophinae. Recent phylogenetic work by Hai Xing indicates that "Hadrosaurus" is placed within the monophyletic group containing all non-lambeosaurine hadrosaurids. Therefore, the traditional Hadrosaurinae should be treated as before: Hadrosauridae is divided into two clades: Hadrosaurinae and Lambeosaurinae., Lizards are a widespread group of squamate reptiles, with over 6,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group, traditionally recognized as the suborder Lacertilia, is defined as all extant members of the Lepidosauria (reptiles with overlapping scales) that are neither sphenodonts (i.e., tuatara) nor snakes  they form an evolutionary grade. While the snakes are recognized as falling phylogenetically within the Toxicofera clade from which they evolved, the sphenodonts are the sister group to the squamates, the larger monophyletic group, which includes both the lizards and the snakes., Kerberosaurus (meaning "Kerberos lizard") was a genus of saurolophine duckbill dinosaur from the late Maastrichtian-age Upper Cretaceous Tsagayan Formation of Blagoveshchensk, Amur Region, Russia (dated to 66 million years ago). It is based on bonebed material including skull remains indicating that it was related to "Saurolophus" and "Prosaurolophus"., Prosaurolophus (meaning "before "Saurolophus"", in comparison to the later dinosaur with a similar head crest) is a genus of hadrosaurid (or duck-billed) dinosaur from the Late Cretaceous of North America. It is known from the remains of at least 25 individuals belonging to two species, including skulls and skeletons, but it remains obscure. Around , its fossils have been found in the late Campanian-age Upper Cretaceous Dinosaur Park Formation in Alberta, and the roughly contemporaneous Two Medicine Formation in Montana, dating to around 75.5-74.0 million years ago. Its most recognizable feature is a small solid crest formed by the nasal bones, sticking up in front of the eyes., Montana is a state in the Western region of the United States. The state's name is derived from the Spanish word (mountain). Montana has several nicknames, although none official, including "Big Sky Country" and "The Treasure State", and slogans that include "Land of the Shining Mountains" and more recently "The Last Best Place". Montana has a border with three Canadian provinces: British Columbia, Alberta, and Saskatchewan, the only state to do so. It also borders North Dakota and South Dakota to the east, Wyoming to the south, and Idaho to the west and southwest. Montana is ranked 4th in size, but 44th in population and 48th in population density of the 50 United States. The western third of Montana contains numerous mountain ranges. Smaller island ranges are found throughout the state. In total, 77 named ranges are part of the Rocky Mountains. The eastern half of Montana is characterized by western prairie terrain and badlands., Ornithischia is an extinct clade of mainly herbivorous dinosaurs characterized by a pelvic structure similar to that of birds. The name "Ornithischia", or "bird-hipped", reflects this similarity and is derived from the Greek ' meaning "of a bird" and ' meaning "hip joint". Birds are members of the saurischian, or "lizard-hipped", dinosaurs., Subject: saurolophini, Relation: parent_taxon, Options: (A) animal (B) area (C) argentina (D) bird (E) california (F) dinosaur (G) edmontosaurus (H) hadrosaurinae (I) human (J) iguanodontia (K) lambeosaurinae (L) lambeosaurini (M) lepidosauria (N) lizard (O) mya (P) ornithischia (Q) ornithopod (R) saurolophinae (S) toxicofera
