Elmer S. Riggs
Elmer Samuel Riggs (January 23, 1869 – March 25, 1963) was an American paleontologist known for his work with the Field Museum of Natural History in Chicago, Illinois. Biography He was born in Trafalgar, Indiana, and moved with his family to Kansas at a young age. He received bachelor's and master's degrees from the University of Kansas and then worked with the American Museum of Natural History. In May 1898 he joined the staff of the Field Museum (then the Field Columbian Museum) as that museum's first paleontologist. Though he was a specialist in fossil mammals, the Field Museum hired him in part to secure dinosaurs for exhibit. In the summer of 1898 he began with a field season in the Oligocene White River beds of South Dakota and Nebraska working under his department chairman, Oliver Farrington, a meteoriticist. Riggs demonstrated a clear facility for fieldwork and was given the opportunity to lead his own expeditions. He conducted his first Field Museum expeditio ...

Trafalgar, Indiana
Trafalgar is a town in Nineveh and Hensley townships, Johnson County, Indiana, United States. The population was 1,101 at the 2010 census. This town is south of Indianapolis. It is the home of the transmitters for WTTV, WTTS, WSOM and WHZN. History Col. Avery M. Buckner is credited for platting a town, in the early 1850s, along a short-lived flat bar railroad that ran between Franklin, and Martinsville. First named Liberty, the name was changed to Trafalgar. Soon Ezekiel W. Morgan came to town to open a store. Denied a site near the railroad, he bought land in a nearby village founded by George Bridges. In 1868, the railroad was rebuilt as the Fairland and Martinsville branch of the Big Four. The post office (and town name) was moved to Morgan's store. By 1870, the “old” and “new” Trafalgars had grown together and were briefly incorporated as one. The current town of Trafalgar was reincorporated in 1946. By the 90s, the town had grown 266%.

Gorgosaurus
''Gorgosaurus'' ( ; ) is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period (Campanian), between about 76.6 and 75.1 million years ago. Fossil remains have been found in the Canadian province of Alberta and the U.S. state of Montana. Paleontologists recognize only the type species, ''G. libratus'', although other species have been erroneously referred to the genus. Like most known tyrannosaurids, ''Gorgosaurus'' was a large bipedal predator, measuring in length and in body mass. Dozens of large, sharp teeth lined its jaws, while its two-fingered forelimbs were comparatively small. ''Gorgosaurus'' was most closely related to ''Albertosaurus'', and more distantly related to the larger ''Tyrannosaurus''. ''Gorgosaurus'' and ''Albertosaurus'' are extremely similar, distinguished mainly by subtle differences in the teeth and skull bones. Some experts consider ''G. libratus'' to be a species of ''Albertosaurus''; thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert T
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Brontosaurus
''Brontosaurus'' (; meaning "thunder lizard" from Greek , "thunder" and , "lizard") is a genus of gigantic quadruped sauropod dinosaurs. Although the type species, ''B. excelsus'', had long been considered a species of the closely related ''Apatosaurus'' and therefore invalid, researchers proposed in 2015 that ''Brontosaurus'' is a genus separate from ''Apatosaurus'' and that it contains three species: ''B. excelsus'', ''B. yahnahpin'', and ''B. parvus''. ''Brontosaurus'' had a long, thin neck and a small head adapted for a herbivorous lifestyle, a bulky, heavy torso, and a long, whip-like tail. The various species lived during the Late Jurassic epoch, in the Morrison Formation of what is now North America, and were extinct by the end of the Jurassic.Foster, J. (2007). ''Jurassic West: The Dinosaurs of the Morrison Formation and Their World''. Indiana University Press. 389pp. Adult individuals of ''Brontosaurus'' are estimated to have measured up to long and weighed up to . ...

Brachiosauridae
The Brachiosauridae ("arm lizards", from Greek ''brachion'' (βραχίων) = "arm" and ''sauros'' = "lizard") are a family or clade of herbivorous, quadrupedal sauropod dinosaurs. Brachiosaurids had long necks that enabled them to access the leaves of tall trees that other sauropods would have been unable to reach. In addition, they possessed thick spoon-shaped teeth which helped them to consume tough plants more efficiently than other sauropods. They have also been characterized by a few unique traits or synapomorphies; dorsal vertebrae with 'rod-like' transverse processes and an ischium with an abbreviated pubic peduncle. ''Brachiosaurus'' is one of the best-known members of the Brachiosauridae, and was once thought to be the largest land animal to ever live. Brachiosaurids thrived in the regions which are now North and South America, Africa, Europe, and Asia. They first appear in the fossil record in the Late Jurassic Period (possibly even earlier in the Middle Jurassic) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruita, Colorado
The City of Fruita is a home rule municipality located in western Mesa County, Colorado, United States. The city population was 13,395 at the 2020 United States Census. Fruita is a part of the Grand Junction, CO Metropolitan Statistical Area and lies within the Grand Valley. The geography is identified by the bordering Colorado River (historically known as the Grand River) on the southern edge of town, the Uncompahgre Plateau known for its pinyon-juniper landscape, and the Book Cliffs range on the northern edge of the Grand Valley. Originally home to the Ute people, white farmers settled the town after founder William Pabor in 1884. Ten years later, Fruita was incorporated.

Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, are among ...

Torvosaurus Tanneri
''Torvosaurus'' () is a genus of carnivorous megalosaurid theropod dinosaur that lived approximately 165 to 148 million years ago during the late Middle and Late Jurassic period (Callovian to Tithonian stages) in what is now Colorado, Portugal, Germany, and possibly England, Spain, Tanzania, and Uruguay. It contains two currently recognized species, ''Torvosaurus tanneri'' and ''Torvosaurus gurneyi'', plus a third species from Germany that is currently unnamed. In 1979 the type species ''Torvosaurus tanneri'' was named: it is a large, heavily built, bipedal carnivore, that could grow to a length of about . ''T. tanneri'' was among the largest carnivores of its time, together with ''Epanterias'' and ''Saurophaganax'' (which could both be synonyms for ''Allosaurus''). Specimens referred to ''Torvosaurus gurneyi'' were measured up to long. Based on bone morphology, ''Torvosaurus'' is thought to have had short but very powerful arms.

Colorado
Colorado (, other variants) is a state in the Mountain West subregion of the Western United States. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the eighth most extensive and 21st most populous U.S. state. The 2020 United States census enumerated the population of Colorado at 5,773,714, an increase of 14.80% since the 2010 United States census. The region has been inhabited by Native Americans and their ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. "''Colorado''" is the Spanish adjective meaning "ruddy", the color of the Fountain Formation outcroppings found up and down the Front Range of the Rocky Mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
