supports: 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. 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 Cerro del Pueblo Formation is a geological formation in Coahuila, Mexico whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. The formation has been dated to between 72.5 Ma and 71.4 million years old. Coahuila, formally Coahuila de Zaragoza, officially the Free and Sovereign State of Coahuila de Zaragoza, is one of the 31 states which, along with Mexico City, compose the 32 Federal Entities of Mexico. The state is located in Northeastern Mexico on the US border. Guatemala (, or ), officially the Republic of Guatemala, is a country in Central America bordered by Mexico to the north and west, the Pacific Ocean to the southwest, Belize to the northeast, the Caribbean to the east, Honduras to the east and El Salvador to the southeast. With an estimated population of around 15.8 million, it is the most populated state in Central America. A representative democracy, Guatemala's capital and largest city is Nueva Guatemala de la Asunción, also known as Guatemala City. Bean is a common name for large seeds of several genera of the flowering plant family Fabaceae (also known as Leguminosae) which are used for human or animal food. Velafrons ( meaning `` sailed forehead '' ) is a genus of lambeosaurine hadrosaurid dinosaur from the Late Cretaceous of Mexico . It is known from a mostly complete skull and partial skeleton of a juvenile individual , with a bony crest on the forehead . Its fossils were found in the late Campanian - age Upper Cretaceous Cerro del Pueblo Formation ( about 72 million years old ) , near Rincon Colorado , Coahuila , Mexico . The type specimen is CPC - 59 , and the type species is V. coahuilensis . Velafrons was most similar to young specimens of Corythosaurus and Hypacrosaurus , and was found to be a corythosaurin in the phylogenetic analysis performed by Gates and colleagues in their description of the genus . The skull was large in comparison to skulls from other genera at a similar growth stage , so the crest may have been small in adults or followed a different growth pattern , or it may be that adult Velafrons were also larger than adults of other lambeosaurine genera . Unusually large size is also seen in the Mexican hadrosaurids Kritosaurus sp. and Magnapaulia laticaudus . As a hadrosaurid , Velafrons would have been an herbivore . 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. 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 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. 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. 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. 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. Monterrey, is the capital and largest city of the northeastern state of Nuevo León, in Mexico. The city is anchor to the third-largest metropolitan area in Mexico and is ranked as the ninth-largest city in the nation. Monterrey serves as a commercial center in the north of the country and is the base of many significant international corporations. Guadalajara is the capital and largest city of the Mexican state of Jalisco, and the seat of the municipality of Guadalajara. The city is in the central region of Jalisco in the Western-Pacific area of Mexico. With a population of 1,495,189 it is Mexico's fourth most populous municipality. The Guadalajara Metropolitan Area includes seven adjacent municipalities with a reported population of 4,328,584 in 2009, making it the second most populous metropolitan area in Mexico, behind Mexico City. The municipality is the second most densely populated in Mexico, the first being Ciudad Nezahualcóyotl in the State of Mexico. It is a strong business and economic center in the Bajio region.  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. 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 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. 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. 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.  Mexico (, modern Nahuatl ), officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost two million square kilometers (over 760,000 sq mi), Mexico is the sixth largest country in the Americas by total area and the 13th largest independent nation in the world. With an estimated population of over 120 million, it is the eleventh most populous country and the most populous Spanish-speaking country in the world while being the second most populous country in Latin America. Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León. 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. The Gulf of Mexico is an ocean basin largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Alabama, Florida, Louisiana, Mississippi and Texas border the Gulf on the north, which are often referred to as the "Third Coast" in comparison with the U.S. Atlantic and Pacific coasts, or sometimes the "south coast", in juxtaposition to the Great Lakes region being the "north coast." One of the gulf's seven main areas is the Gulf of Mexico basin. 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". 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. 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. 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. 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. 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. 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. The Late Cretaceous (100.566 Ma) is the younger of two epochs into which the Cretaceous period is divided in the geologic timescale. Rock strata from this epoch form the Upper Cretaceous series. The Cretaceous is named after the white limestone known as chalk which occurs widely in northern France and is seen in the white cliffs of south-eastern England, and which dates from this time. Toluca , officially called Toluca de Lerdo , is the state capital of State of Mexico as well as the seat of the Municipality of Toluca. It is the center of a rapidly growing urban area, now the fifth largest in Mexico. It is located west-southwest of Mexico City, about 40 minutes by car to the western edge of the city. According to the 2010 census, the city of Toluca has a population of 819,561. The city is the fifth largest in Mexico in population. The municipality of Toluca, along with thirteen other municipalities, make up the metropolitan population of 1,775,337 in Greater Toluca , making it the fifth most populous metropolitan area in Mexico.
