Bistahieversor
''Bistahieversor'' (meaning "Bistahi destroyer"), also known as the "Bisti Beast", is a genus of basal Eutyrannosauria, eutyrannosaurian Theropoda, theropod dinosaur. The genus contains only a single known species, ''B. sealeyi'', described in 2010, from the Late Cretaceous of New Mexico. The holotype and a juvenile were found in the Hunter Wash Member of the Kirtland Formation, while other specimens came from the underlying Fossil Forest member of the Fruitland Formation. This dates ''Bistahieversor'' approximately 75.5 to 74.5 million years ago during the Campanian age, found in sediments spanning a million years. Discovery and naming The first remains now attributed to ''Bistahieversor'', a partial skull and skeleton, were described in 1990 as a specimen of ''Aublysodon''. Additional remains, consisting of the incomplete skull and skeleton of a juvenile, were described in 1992. Another complete skull and partial skeleton were found in the Bisti/De-Na-Zin Wilderness, Bisti/De- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kirtland Formation
The Kirtland Formation (originally the Kirtland Shale) is a Sedimentary rock, sedimentary geological formation. Description The Kirtland Formation is the product of alluvial muds and overbank sand deposits from the many channels draining the coastal plain that existed on the Cretaceous Interior Seaway, inland seashore of North America, in the late Cretaceous period. It overlies the Fruitland Formation. It is found in the San Juan Basin in the states of New Mexico and Colorado, in the United States of America. The base of the Kirtland Formation and its lowest sub-unit, the Hunter Wash member, has been dated to 75.02 ± 0.13 Ma. Together with the upper part of the underlying Fruitland Formation, this contains fossils representing the Hunter Wash local fauna. The border between the Hunter Wash member and overlying Farmington member dates to approximately 74 million years ago. The top of the Farmington member and bottom of the overlying De-na-zin member has been radiometrically da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eutyrannosauria
Tyrannosauroidea (meaning 'tyrant lizard forms') is a superfamily (or clade) of coelurosaurian theropod dinosaurs that includes the family Tyrannosauridae as well as more basal relatives. Tyrannosauroids lived on the Laurasian supercontinent beginning in the Jurassic Period. By the end of the Cretaceous Period, tyrannosauroids were the dominant large predators in the Northern Hemisphere, culminating in the gigantic ''Tyrannosaurus''. Fossils of tyrannosauroids have been recovered on what are now the continents of North America, Europe and Asia. If Megaraptora is part of Tyrannosauroidea, this would extend the distribution of the group to Australia and South America, and possible fragmentary remains of tyrannosauroids have also been reported from these continents. Tyrannosauroids were bipedal carnivores, as were most theropods, and were characterized by numerous skeletal features, especially of the skull and pelvis. Early in their existence, tyrannosauroids were small predators ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyrannosaurus
''Tyrannosaurus'' () is a genus of large theropod dinosaur. The type species ''Tyrannosaurus rex'' ( meaning 'king' in Latin), often shortened to ''T. rex'' or colloquially t-rex, is one of the best represented theropods. It lived throughout what is now western North America, on what was then an island continent known as Laramidia. ''Tyrannosaurus'' had a much wider range than other tyrannosaurids. Fossils are found in a variety of geological formations dating to the latest Campanian-Maastrichtian ages of the late Cretaceous period, 72.7 to 66 million years ago, with isolated specimens possibly indicating an earlier origin in the middle Campanian. It was the last known member of the tyrannosaurids and among the last non- avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. Like other tyrannosaurids, ''Tyrannosaurus'' was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, ...

Tyrannosaurinae
Tyrannosaurinae (or tyrannosaurines) is one of the two extinct subfamilies of Tyrannosauridae, a family of coelurosaurian theropods that consists of at least three tribes and several genera. All fossils of these genera have been found in the Late Cretaceous deposits of western North America and east Asia. Compared to the related subfamily Albertosaurinae, tyrannosaurines overall are more robust and larger though the alioramins were gracile by comparison. This subfamily also includes '' Lythronax'', one of the oldest known tyrannosaurid genera, as well as the youngest and most famous member of the group, ''Tyrannosaurus rex''. History of discovery The first remains of tyrannosaurids were uncovered during expeditions led by the Geological Survey of Canada, which located numerous scattered teeth. These distinctive dinosaur teeth were given the name '' Deinodon'' ("terrible tooth") by Joseph Leidy in 1856. In 1892 Edward Drinker Cope described more tyrannosaur material in the f ...

Aublysodon
''Aublysodon'' (“backwards-flowing tooth") is a dubious genus of carnivorous dinosaurs known only from the Judith River Formation in Montana, which has been dated to the late Campanian age of the late Cretaceous period (about 75 million years ago). The only currently recognized species, ''Aublysodon mirandus'', was named by paleontologist Joseph Leidy in 1868. It is sometimes considered dubious now, because the type specimen consists only of an isolated premaxillary (front) tooth. Although this specimen is now lost, similar teeth have been found in many US states, western Canada, and Asia. These teeth almost certainly belong to juvenile tyrannosaurine tyrannosaurids, but most have not been identified to species level. However, it is likely that the type tooth (and therefore the name ''Aublysodon mirandus'' itself) belongs to one of the species in the genus '' Daspletosaurus'', which was present in contemporary formations, and which matches specific details of the original t ...

Daspletosaurus
''Daspletosaurus'' ( ; meaning "frightful lizard") is a genus of tyrannosaurid dinosaur that lived in Laramidia between about 77 and 74.4 million years ago, during the Late Cretaceous Period. The genus ''Daspletosaurus'' contains three named species. Fossils of the earlier type species, ''D. torosus'', have been found in Alberta, while fossils of a later species, ''D. horneri'', have been found only in Montana. ''D. wilsoni'' has been suggested as an intermediate species between ''D. torosus'' and ''D. horneri'' that evolved through anagenesis, though further research may be required to definitively support the theory. There are also multiple specimens which may represent new species of ''Daspletosaurus'' from Alberta and Montana, but these have not been formally described. The taxon '' Thanatotheristes'' has been suggested to represent a species of ''Daspletosaurus'', ''D. degrootorum'', but this has not been widely supported. ''Daspletosaurus'' is closely related to the much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Mexico Museum Of Natural History And Science
The New Mexico Museum of Natural History and Science is a natural history and science museum in Albuquerque, New Mexico near Old Town Albuquerque. The Museum was founded in 1986. It operates as a public revenue facility of the New Mexico Department of Cultural Affairs. History The museum was created by an act of the New Mexico Legislature signed into law by Governor Bruce King in March, 1980. Part of the motivation for the project was to provide a home for some of the numerous dinosaur fossils discovered in New Mexico rather than sending them to out-of-state institutions. Ground was broken on a site near Old Town and the museum opened on January 11, 1986. It was one of the first new natural history museums in the U.S. in decades and represented an updated approach focusing on interactive multimedia exhibits rather than large collections of specimens displayed in glass cases. An astronomy center including an observatory and planetarium was added to the museum in 1999. This was o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
