George Blasing
''Jurassic Fight Club'' (titled ''Dinosaur Secrets'' in Australia/the UK) is a paleontology-based television series on History channel which premiered in the US in July 2008. ''Jurassic Fight Club'' was hosted by George Blasing, a self-taught paleontologist, and also features well-known paleontologists such as Thomas R. Holtz Jr., Lawrence Witmer, Phillip J. Currie, and others. The show ran for one season of 12 episodes and was not renewed. Summary Scientists study the battles of prehistoric creatures, such as dinosaurs, before they became extinct. Each episode features a forensic-styled breakdown of a prehistoric battle. Based on fossil evidence and paleontologic analysis, a computer-generated imagery rendering of the battle, based on the evidence and the imagination of George Blasing (the show's host) is the final act of each episode. In most cases, the battles are based on actual fossil finds, although in several episodes, scientists simply put two contemporaneous prehi ...

Tenontosaurus
''Tenontosaurus'' ( ; ) is a genus of medium- to large-sized ornithopod dinosaur. It was a relatively medium sized ornithopod, reaching in length and in body mass. It had an unusually long, broad tail, which like its back was stiffened with a network of bony tendons. The genus is known from the late Aptian to Albian ages of the Early Cretaceous period sediments of western North America, dating between 115 and 108 million years ago. It contains two species, ''Tenontosaurus tilletti'' (described by John Ostrom in 1970) and ''Tenontosaurus dossi'' (described by Winkler, Murry, and Jacobs in 1997). Many specimens of ''T. tilletti'' have been collected from several geological formations throughout western North America. ''T. dossi'' is known from only a handful of specimens collected from the Twin Mountains Formation of Parker County, Texas. History of discovery The first ''Tenontosaurus'' fossil was found in Big Horn County, Montana by an American Museum of Natural Histo ...

Pachyrhinosaurus
''Pachyrhinosaurus'' (meaning in Greek "thick-nosed lizard", from ' (), thick; ' (), nose; and (), lizard) is an extinct genus of centrosaurine ceratopsid dinosaur from the Late Cretaceous period of North America. The first examples were discovered by Charles M. Sternberg in Alberta, Canada, in 1946, and named in 1950. Over a dozen partial skulls and a large assortment of other fossils from various species have been found in Alberta and Alaska. A great number were not available for study until the 1980s, resulting in a relatively recent increase of interest in ''Pachyrhinosaurus''. Three species have been identified. ''P. lakustai'', from the Wapiti Formation, the bonebed horizon of which is roughly equivalent age to the upper Bearpaw and lower Horseshoe Canyon Formations, is known to have existed from about 73.5–72.5 million years ago. ''P. canadensis'' is younger, known from the lower Horseshoe Canyon Formation, about 71.5–71 Ma ago and the St. Mary River Formation. ...

American Lion
''Panthera atrox'', better known as the American lion, also called the North American lion, or American cave lion, is an extinct pantherine cat that lived in North America during the Pleistocene epoch and the early Holocene epoch, about 340,000 to 11,000 years ago. Its fossils have been excavated from Alaska to Mexico. Genetic analysis has shown that the American lion and the Late Pleistocene Eurasian cave lion (''Panthera spelaea'') are sister lineages. It was about 25% larger than the modern lion, making it one of the largest known felids. History and taxonomy Initial discovery and North American fossils The first specimen now assigned to ''Panthera atrox'' was collected in the 1830s and placed in the collection of by William Henry Huntingtion Esquire, who announced their discovery to the American Philosophical Society on April 1, 1836 and placed with other fossils from Huntington's collection in the Academy of Natural Sciences in Philadelphia. The specimen had been c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctodus
''Arctodus'' is an extinct genus of short-faced bear that inhabited North America during the Pleistocene (~2.5 Mya until 12,000 years ago). There are two recognized species: the lesser short-faced bear (''Arctodus pristinus'') and the giant short-faced bear (''Arctodus simus''). Both species are relatively rare in the fossil record- ''A. pristinus'' was largely restricted to the Early Pleistocene of the eastern United States, whereas ''A. simus'' had a cosmopolitan range, with most finds being from the Late Pleistocene of the US, Mexico and Canada. ''A. simus'' evolved from ''A. pristinus'', but both species likely overlapped in the Middle Pleistocene. Of these species, ''A. simus'' was larger, is known from more complete remains, and is considered one of the most charismatic of North America's megafauna. Today considered to be an enormous omnivore, ''Arctodus simus'' is believed to be one of the largest known terrestrial mammalian carnivorans that has ever existed. However, ''Arct ...

Gastonia (dinosaur)
''Gastonia'' is a genus of herbivorous ankylosaurian dinosaur from the Early Cretaceous of North America, around 139 to 125 million years ago. It is often considered a nodosaurid closely related to ''Polacanthus''. ''Gastonia'' has a sacral shield and large shoulder spikes. Discovery and species The type specimen of ''Gastonia burgei'' ( CEUM 1307) was discovered in a bonebed from the limestone strata of the lower Cedar Mountain Formation in Yellow Cat Quarry, Grand County, eastern Utah, the type specimen consisting of a single skull. The type specimen was found alongside 4 partial skeletons of ''Gastonia that'' were placed as paratypes, along with the type specimen of ''Utahraptor'' and an Iguanodontid. ''Gastonia'' is among the most common dinosaur fossils in the Cedar Mountain Formation, with many individuals being found across several quarries in the southwest.Kirkland, J.I. (1998). A polacanthine ankylosaur (Ornithischia: Dinosauria) from the Early Cretaceous (Barremian) o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albertosaurus
''Albertosaurus'' (; meaning "Alberta lizard") is a genus of tyrannosaurid theropod dinosaurs that lived in western North America during the Late Cretaceous Period, about 71 million years ago. The type species, ''A. sarcophagus'', was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named, although an indeterminate species ("cf. ''Albertosaurus'' sp.") has been discovered in the Corral de Enmedio and Packard Formations in Mexico. Scientists disagree on the content of the genus, with some recognizing ''Gorgosaurus libratus'' as a second species. As a tyrannosaurid, ''Albertosaurus'' was a bipedal predator with tiny, two-fingered hands and a massive head that had dozens of large, sharp teeth. It may have been an apex predator in its local ecosystem. While ''Albertosaurus'' was large for a theropod, it was much smaller than its larger and more famous relative ''Tyrannosaurus rex'', growing up to in length and weighing . ...

Utahraptor
''Utahraptor'' (meaning "Utah's thief") is a genus of large dromaeosaurid dinosaur that lived in North America during the Early Cretaceous period. It was a heavy-built, ground-dwelling, bipedal carnivore. It contains a single species, ''Utahraptor ostrommaysi'', which is one of the largest-known members of the family Dromaeosauridae, measuring long and weighing . Discovery and naming The first specimens of ''Utahraptor'' were found in 1975 by Jim Jensen in the Dalton Wells Quarry in east-central Utah, near the town of Moab, but did not receive much attention. After a find of a large foot-claw by Carl Limone in October 1991, James Kirkland, Robert Gaston, and Donald Burge uncovered further remains of ''Utahraptor'' in 1991 in the Gaston Quarry in Grand County, Utah, within the Yellow Cat and Poison Strip members of the Cedar Mountain Formation. The holotype of ''Utahraptor'', CEUM 184v.86 consists of a second pedal ungual, with potentially assigned elements from other specim ...

Brygmophyseter
''Brygmophyseter'', known as the biting sperm whale, is an extinct genus of toothed whale in the sperm whale family with one species, ''B. shigensis''. When it was first described in 1994, the species was placed in the genus ''Scaldicetus'' based on tooth morphology, but this was later revised in 1995. In 2006, it was classified into the genus ''Naganocetus'', which is considered to be a junior synonym. The only known specimen, a nearly complete skeleton, was dated to be around 14–15 million years old. ''Brygmophyseter'' is thought to have been long, and it probably had 11 or 12 teeth in the upper and lower jaws. ''Brygmophyseter'' is part of a group of macroraptorial sperm whales (often shortened to "raptorial") which tended to be apex predators using their large teeth to catch struggling prey such as whales. It had a spermaceti organ which was probably used for biosonar like in the modern sperm whale. The whale has made an appearance on The History Channel's TV series ' ...

Megalodon
Megalodon (''Otodus megalodon''), meaning "big tooth", is an extinct species of mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Pliocene epochs. It was formerly thought to be a member of the family Lamnidae and a close relative of the great white shark (''Carcharodon carcharias''). However, it is now classified into the extinct family Otodontidae, which diverged from the great white shark during the Early Cretaceous. While regarded as one of the largest and most powerful predators to have ever lived, the megalodon is only known from fragmentary remains, and its appearance and maximum size are uncertain. Scientists differ on whether it would have more closely resembled a stockier version of the great white shark, the whale shark (''Rhincodon typus''), the basking shark (''Cetorhinus maximus'') or the sand tiger shark (''Carcharias taurus''). The most recent estimate with the least error range suggests a maximum length e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Brea Tar Pits
La Brea Tar Pits is an active paleontological research site in urban Los Angeles. Hancock Park was formed around a group of tar pits where natural asphalt (also called asphaltum, bitumen, or pitch; ''brea'' in Spanish) has seeped up from the ground for tens of thousands of years. Over many centuries, the bones of trapped animals have been preserved. The George C. Page Museum is dedicated to researching the tar pits and displaying specimens from the animals that died there. La Brea Tar Pits is a registered National Natural Landmark. Formation Tar pits are composed of heavy oil fractions called gilsonite, which seeps from the Earth as oil. Crude oil seeps up along the 6th Street Fault from the Salt Lake Oil Field, which underlies much of the Fairfax District north of Hancock Park. The oil reaches the surface and forms pools, becoming asphalt as the lighter fractions of the petroleum biodegrade or evaporate. The asphalt then normally hardens into stubby mounds. The pools and mou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camarasaurus
''Camarasaurus'' ( ) was a genus of quadrupedal, herbivorous dinosaurs and is the most common North American sauropod fossil. Its fossil remains have been found in the Morrison Formation, dating to the Late Jurassic epoch (Kimmeridgian to Tithonian stages), between 155 and 145 million years ago. ''Camarasaurus'' presented a distinctive cranial profile of a blunt snout and an arched skull that was remarkably square, typical of basal Macronarians. The name means "chambered lizard", referring to the hollow chambers, known as pleurocoels, in its cervical vertebrae (Greek (') meaning "vaulted chamber", or anything with an arched cover, and (') meaning "lizard". ''Camarasaurus'' contains four species that are commonly recognized as valid: ''Camarasaurus grandis'', '' Camarasaurus lentus'', '' Camarasaurus lewisi'', and ''Camarasaurus supremus''. ''C. supremus'', the type species, is the largest and geologically youngest of the four. ''Camarasaurus'' is the type genus of Camarasau ...
