Allosaurus
''Allosaurus'' ( ) is an extinct genus of theropod dinosaur that lived 155 to 145 million years ago during the Late Jurassic period ( Kimmeridgian to late Tithonian ages). The first fossil remains that could definitively be ascribed to this genus were described in 1877 by Othniel C. Marsh. The name "''Allosaurus''" means "different lizard", alluding to its lightweight , which Marsh believed were unique. The genus has a very complicated taxonomy and includes at least three valid species, the best known of which is ''A. fragilis''. The bulk of ''Allosaurus'' remains come from North America's Morrison Formation, with material also known from the Alcobaça Formation and Lourinhã Formation in Portugal. It was known for over half of the 20th century as '' Antrodemus'', but a study of the abundant remains from the Cleveland-Lloyd Dinosaur Quarry returned the name "''Allosaurus''" to prominence. As one of the first well-known theropod dinosaurs, it has long attracted attention ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edmontosaurus
''Edmontosaurus'' ( ) (meaning "lizard from Edmonton"), with the second species often colloquially and historically known as ''Anatosaurus'' or ''Anatotitan'' (meaning "duck lizard" and "giant duck"), is a genus of hadrosaurid (duck-billed) dinosaur. It contains two known species: ''Edmontosaurus regalis'' and ''Edmontosaurus annectens''. Fossils of ''E. regalis'' have been found in rocks of western North America that date from the late Campanian Stage (stratigraphy), age of the Cretaceous Period (geology), period 73 million years ago, while those of ''E. annectens'' were found in the same geographic region from rocks dated to the end of the Maastrichtian age, 66 million years ago. ''Edmontosaurus'' was one of the last non-bird, avian dinosaurs ever to exist, and lived alongside dinosaurs like ''Triceratops'', ''Tyrannosaurus'', ''Ankylosaurus'', and ''Pachycephalosaurus'' shortly before the Cretaceous–Paleogene extinction event. ''Edmontosaurus'' included two of the lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pachyrhinosaurus
''Pachyrhinosaurus'' (from Ancient Greek ' (), thick; ' (), nose; and (), lizard) is a 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 in 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. Fossils of the youngest s ...

American Lion
The American lion (''Panthera atrox'' (), with the species name meaning "savage" or "cruel", also called the North American lion) is an extinct pantherine cat native to North America during the Late Pleistocene from around 129,000 to 12,800 years ago. Genetic evidence suggests that its closest living relative is the lion (''Panthera leo''), with the American lion representing an offshoot from the lineage of the largely Eurasian cave lion (''Panthera spelaea''), from which it is suggested to have split around 165,000 years ago. Its fossils have been found across North America, from Canada to Mexico. It was about 25% larger than the modern lion, making it one of the largest known felids to ever exist, and a dominant apex predator in North American ecosystems, alongside the sabertooth cats '' Smilodon'' and ''Homotherium''. It has been suggested, like modern lions, they were social animals, although this is not known for sure. The American lion became extinct as part of the end ...

Arctodus
''Arctodus'' is an extinct genus of short-faced bear that inhabited North America during the Pleistocene (~2.6 Year#mya, Mya until 12,800 years ago). There are two recognized species: the lesser short-faced bear (''Arctodus pristinus'') and the giant short-faced bear (''Arctodus simus''). Of these species, ''A. simus'' was larger, is known from more complete remains, and is considered one of the best known members of North America's extinct Ice Age megafauna. ''A. pristinus'' was largely restricted to the Early Pleistocene of the eastern United States, whereas ''A. simus'' had a broader range, with most finds being from the Late Pleistocene of the United States, Mexico and Canada. ''A. simus'' evolved from ''A. pristinus'', but both species likely overlapped in the Middle Pleistocene. Both species are relatively rare in the fossil record. Today considered to be an enormous omnivore, ''Arctodus simus'' is believed to be one of the largest known terrestrial carnivorans that has ever e ...

Gastonia (dinosaur)
''Gastonia'' is a genus of herbivorous ankylosaurian dinosaur from the Early Cretaceous of North America, around 139 to 125.77 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).

Albertosaurus
''Albertosaurus'' (; meaning "Alberta lizard") is a genus of large tyrannosaurid theropod dinosaur that lived in northwestern North America during the early to middle Maastrichtian age of 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 of Mexico. Scientists disagree on the content of the genus and some recognize '' Gorgosaurus libratus'' as a second species. As a tyrannosaurid, ''Albertosaurus'' was a bipedal predator with short arms, two-fingered hands, and a massive head with dozens of large, sharp teeth, a strong sense of smell, powerful binocular vision, and a bone crushing bite force. It may have even been the apex predator in its local ecosystem. While ''Albertosaurus'' was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utahraptor
''Utahraptor'' (meaning "Utah's predator") is a genus of large dromaeosaurid (a group of feathered carnivorous theropods) dinosaur that lived during the Early Cretaceous period from around 139 to 135 million years ago in what is now the United States. The genus was described in 1993 by American paleontologist James Kirkland and colleagues with the type species ''Utahraptor ostrommaysi'', based on fossils that had been unearthed earlier from the Cedar Mountain Formation of Utah. Later, many additional specimens were described including those from the skull and postcranium in addition to those of younger individuals. The genus contains a single species, ''Utahraptor ostrommaysi''. It is the largest-known member of the family Dromaeosauridae, measuring about long and typically weighing around . As a heavily built, ground-dwelling, bipedal carnivore, its large size and variety of unique features have earned it attention in both pop culture and the scientific community. The jaws ...

Brygmophyseter
''Brygmophyseter'', known as the biting sperm whale, is an extinct genus of toothed whale in the Physeteroidea, 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 (biology), morphology, but this was later revised in 2006. A month later since the naming of ''Brygmophyseter'', another study classified this species 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 16–15 million years old (middle Miocene). ''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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megalodon
''Otodus megalodon'' ( ; meaning "big tooth"), Common name, commonly known as megalodon, is an extinction, extinct species of giant mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Early Pliocene epochs. ''O. megalodon'' was formerly thought to be a member of the family (biology), family Lamnidae and a close relative of the great white shark (''Carcharodon carcharias''), but has been reclassified into the extinct family Otodontidae, which Speciation, 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, megalodon is only known from fragmentary remains, and its appearance and maximum size are uncertain. Scientists have argued whether its body form was more stocky or elongated than the modern lamniform sharks. Maximum body length estimates between based on various analyses have been proposed, though the Mode (statistics), modal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Brea Tar Pits
La Brea Tar Pits comprise an active Paleontological site, paleontological research site in urban Los Angeles. Hancock Park was formed around a group of tar pits where natural Bitumen, 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 crude oil, heavy oil fractions, called gilsonite, which seep 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 the ...
