Information:  - 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.  - 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.  - 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.  - 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.  - 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.  - The Judith River Formation is a fossil-bearing geologic formation in Montana, and is part of the Judith River Group. It dates to the upper Cretaceous, between 80 and 75 million years ago, corresponding to the "Judithian" land vertebrate age. It was laid down during the same time period as portions of the Two Medicine Formation of Montana and the Oldman Formation of Alberta. It is an historically important formation, explored by early American paleontologists such as Edward Drinker Cope, who named several dinosaurs from scrappy remains found here on his 1876 expedition (such as "Monoclonius"). Modern work has found nearly complete skeletons of the hadrosaurid "Brachylophosaurus".  - In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs.  - Trachodon ( meaning `` rough tooth '' ) is a dubious genus of hadrosaurid dinosaur based on teeth from the Campanian - age Upper Cretaceous Judith River Formation of Montana , U.S. It is a historically important genus with a convoluted taxonomy that has been all but abandoned by modern dinosaur paleontologists . Despite being used for decades as the iconic duckbill dinosaur per antonomasia the material it is based on is composed of teeth from both duckbills and ceratopsids ( their teeth have a distinctive double root ) , and its describer , Joseph Leidy , came to recognize the difference and suggested limiting the genus to what would now be seen as ceratopsid teeth . Restricted to the duckbill teeth , it may have been a lambeosaurine .  - A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.  - 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.  - 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.  - The Judith River Group is a group of geologic formations in western North America dating from the late Cretaceous and noted as a site for the extensive excavation of dinosaur fossils. The formation is named after the Judith River in Montana. The group is also called the Judith River Wedge. It is stratigraphically equivalent with the Belly River Group in Alberta.  - Monoclonius (meaning "single sprout") is a dubious genus of herbivorous ceratopsian dinosaurs found in the Late Cretaceous layers of the Judith River Formation in Montana, northern US, and the uppermost rock layers of the Dinosaur Park Formation in Alberta, Canada dated to between 75 and 74.6 million years ago.  - 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).  - The Oldman Formation is a stratigraphic unit of Late Cretaceous (Campanian stage) age that underlies much of southern Alberta, Canada. It consists primarily of sandstones that were deposited in fluvial channel and floodplain environments. It was named for exposures along the Oldman River between its confluence with the St. Mary River and the city of Lethbridge, and it is known primarily for its dinosaur remains and other fossils.  - 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.  - 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.  - 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.  - The Campanian is, in the ICS' geologic timescale, the fifth of six ages of the Late Cretaceous epoch (or, in chronostratigraphy: the fifth of six stages in the Upper Cretaceous series). The Campanian spans the time from 83.6 ± 0.7 Ma to 72.1 ± 0.6 Ma (million years ago). It is preceded by the Santonian and it is followed by the Maastrichtian.  - 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.  - 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.  - 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.  - Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus.  - The Santonian is an age in the geologic timescale or a chronostratigraphic stage. It is a subdivision of the Late Cretaceous epoch or Upper Cretaceous series. It spans the time between 86.3 ± 0.7 mya (million years ago) and 83.6 ± 0.7 mya. The Santonian is preceded by the Coniacian and is followed by the Campanian.  - 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.  - Brachylophosaurus (or ; meaning "short-crested lizard", Greek "brachys" = short + "lophos" = crest + "sauros" = lizard, referring to its small crest) was a mid-sized member of the hadrosaurid family of dinosaurs. It is known from several skeletons and bonebed material from the Judith River Formation of Montana and the Oldman Formation of Alberta, living about 78 million years ago.  - The Triassic is a geologic period and system which spans 50.9 million years from the end of the Permian Period million years ago (Mya), to the beginning of the Jurassic Period Mya. The Triassic is the first period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic was named in 1834 by Friedrich von Alberti, after the three distinct rock layers ("tri" meaning "three") that are found throughout Germany and northwestern Europered beds, capped by marine limestone, followed by a series of terrestrial mud- and sandstonescalled the "Trias".  - The TriassicJurassic extinction event marks the boundary between the Triassic and Jurassic periods, , and is one of the major extinction events of the Phanerozoic eon, profoundly affecting life on land and in the oceans. In the seas, a whole class (conodonts) and 34% of marine genera disappeared. On land, all pseudosuchians (non-ornithodiran archosaurs) other than crocodylomorphs (Sphenosuchia and Crocodyliformes), some remaining therapsids, and many of the large amphibians became extinct.  - 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.  - 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.  - The Paleogene (or ; also spelled Palaeogene or Palæogene; informally Lower Tertiary) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago (Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The Paleogene is most notable for being the time during which mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of the CretaceousPaleogene extinction event that ended the preceding Cretaceous Period.   - 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.  - 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.
