Brachylophosaurus
''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, the Wahweap Formation of Utah and the Oldman Formation of Alberta, living about 81-76.7 million years ago. Discovery and later finds ''Brachylophosaurus'' was first named and described by Charles Mortram Sternberg in 1953 for a skull and partial skeleton, holotype NMC 8893, which he had found in 1936 near Steveville in Alberta, and which was at first thought to belong to ''Gryposaurus'' (or ''Kritosaurus'' as it was known at the time). The type species is ''Brachylophosaurus canadensis''. The generic name is derived from Greek βραχύς, ''brachys'', "short", and λόφος, ''lophos'', "crest of a helmet". The specific name refers to the provenanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Judith River Formation
The Judith River Formation is a fossil-bearing geologic formation in Montana, and is part of the Judith River Group. It dates to the Late Cretaceous, between 79 and 75.3 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 MontanaSullivan, R.M. and Lucas, S. G. (2006).

Hadrosaurid
Hadrosaurids (), or duck-billed dinosaurs, are members of the ornithischian family Hadrosauridae. This group is known as the duck-billed dinosaurs for the flat duck-bill appearance of the bones in their snouts. The ornithopod family, which includes genera such as ''Edmontosaurus'' and '' Parasaurolophus'', was a common group of herbivores during the Late Cretaceous Period. Hadrosaurids are descendants of the Upper Jurassic/Lower Cretaceous iguanodontian dinosaurs and had a similar body layout. Hadrosaurs were among the most dominant herbivores during the Late Cretaceous in Asia and North America, and during the close of the Cretaceous several lineages dispersed into Europe, Africa, South America and Antarctica. Like other ornithischians, hadrosaurids had a predentary bone and a pubic bone which was positioned backwards in the pelvis. Unlike more primitive iguanodonts, the teeth of hadrosaurids are stacked into complex structures known as dental batteries, which acted as effectiv ...

Malta, Montana
Malta ( ) is a city in, and the county seat of, Phillips County, Montana, United States, located at the intersection of U.S. Routes 2 and 191. The population was 1,860 at the 2020 census. History After James Hill and his partners built the St. Paul, Minneapolis, and Manitoba railway (which in 1890 became the Great Northern Railway) across Montana's "High Line" in 1887, Malta evolved from rail siding number 54. What came to be Saco, Montana, to the east and Dodson, Montana, to the west grew from other nearby sidings. A post office was established in Malta in 1890. Its name is said to have been determined by a spin of the globe by a Great Northern official whose finger came to rest on the island of Malta in the Mediterranean Sea. On July 3, 1901, Kid Curry (Harvey Logan), as part of Butch Cassidy's Wild Bunch, robbed a train just west of Malta, near Wagner, Montana, making off with about $40,000. One of the best preserved dinosaurs ever discovered and one of only four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wahweap Formation
The Wahweap Formation of the Grand Staircase–Escalante National Monument is a geological formation in southern Utah and northern Arizona, around the Lake Powell region, whose strata date back to the Late Cretaceous (Campanian stage). Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, North America)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 574–588. . Age The Wahweap formation is divided into four members, which are listed below with their respective ages: * Last Chance Creek Member: 82.17-81.55 Ma * Reynolds Point Member: 81.55-80.61 Ma * Coyote Point Member: 80.61-79 Ma * Pardner Canyon Member: 79-77.29 Ma Paleobiota Invertebrates The Wahweap Formation shows a substantial amount of invertebrate activity ranging from fossilized insect burrows in petrified logs to var ...

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 ...

Oldman Formation
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.Eberth, D.A. and Hamblin A.P. 1993. Tectonic, stratigraphic, and sedimentologic significance of a regional discontinuity in the upper Judith River Group (Belly River wedge) of southern Alberta, Saskatchewan, and northern Montana. Canadian Journal of Earth Sciences 30: 174-200. Lithology The Oldman Formation is composed primarily of light-colored, fine-grained sandstones. They are upward-fining, lenticular to sheet-like bodies that are yellowish, steep-faced and blocky in outcrop. The formation also includes lesser amounts of siltstone and mudstone.Ebe ...

Charles Mortram Sternberg
Charles Mortram Sternberg (1885–1981) was an American-Canadian fossil collector and paleontologist, son of Charles Hazelius Sternberg. Late in his career, he collected and described ''Pachyrhinosaurus'', ''Brachylophosaurus'', ''Parksosaurus'' and ''Edmontonia''. A contemporary author wrote, "No published study of Canadian dinosaurs is possible today without citing one or another of Sternberg's papers." Early life Charles Mortram Sternberg was born in Lawrence, Kansas, from a family of famous American fossil collectors. Sternberg's highest level of education was a Kansas high school degree. Career Sternberg moved with his father and two brothers, Levi and George, to Ottawa, Ontario, Canada in 1912. The four began working in Alberta collecting dinosaurs on behalf of the Geological Survey of Canada. This work was in competition with the American Museum of Natural History (New York) who were collecting many fossil skeletons and shipping them out of Canada. Following Lawrence ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jack Horner (paleontologist)
John Robert (‘Jack’) Horner (born June 15, 1946) is an American paleontologist most famous for describing ''Maiasaura'', providing the first clear evidence that some dinosaurs cared for their young. In addition to his paleontological discoveries, Horner served as the technical advisor for the first five '' Jurassic Park'' films, had a cameo appearance in '' Jurassic World'', and served as a partial inspiration for one of the lead characters of the franchise, Dr. Alan Grant. Horner studied at the University of Montana, although he did not complete his degree due to undiagnosed dyslexia, and was awarded a Doctorate in Science ''honoris causa''. He retired from Montana State University on July 1, 2016, although he claims to have been pushed out of the Museum of the Rockies after having married an undergraduate student and now teaches as a Presidential Fellow at Chapman University. Biography Horner was born and raised near Shelby, Montana. He was eight years old when he fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
