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. 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%. The name of the town commemorates the Battle of Trafalgar. Geography According to the 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gorgosaurus
''Gorgosaurus'' ( ; ) is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period (Campanian), between about 76.5 and 75 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''; th ... [...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'' () "fame, glory, honour, praise, renown, godlike" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin.Reaney & Wilson, 1997. ''Dictionary of English Surnames''. Oxford University Press. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe, the name 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 En ...

Brontosaurus
''Brontosaurus'' (; meaning "thunder lizard" from the Ancient Greek, Greek words , "thunder" and , "lizard") is a genus of herbivorous sauropod dinosaur that lived in present-day United States during the Late Jurassic period. It was described by American paleontologist Othniel Charles Marsh in 1879, the type species being dubbed ''B. excelsus'', based on a partial skeleton lacking a skull found in Como Bluff, Wyoming. In subsequent years, two more species of ''Brontosaurus'' were named: ''B. parvus'' in 1902 and ''B. yahnahpin'' in 1994. ''Brontosaurus'' lived about 156 to 146 million years ago (mya) during the Kimmeridgian and Tithonian ages in the Morrison Formation of what is now Utah and Wyoming. For decades, the animal was thought to have been a Synonym (taxonomy), taxonomic synonym of its close relative ''Apatosaurus'', but a 2015 study by Emmanuel Tschopp and colleagues found it to be distinct. It has seen widespread representation in popular culture, being the archetyp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic Geological period, period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the #Evolutionary history, evolution of dinosaurs is a subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya and their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, Evolution of birds, having evolved from earlier Theropoda, 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 taxonomy (biology), taxonomic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torvosaurus Tanneri
''Torvosaurus'' () is a genus of large megalosaurine theropod dinosaur that lived approximately 165 to 148 million years ago during the Callovian to Tithonian ages of the late Middle and Late Jurassic period 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 unnamed species from Germany. In 1979, the type species ''Torvosaurus tanneri'' was named. Measuring around long and weighing approximately , ''T. tanneri'' was among the largest terrestrial carnivores in North America during the Late Jurassic. Specimens of ''Torvosaurus gurneyi'' were measured up to in length and in body mass, suggesting that it was much larger than ''T. tanneri'' and was the largest terrestrial carnivore in Europe during the Late Jurassic. Based on bone morphology, ''Torvosaurus'' is thought to have had very powerful short arms. Discovery ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
