Paleoworld
''Paleoworld'' (''Jurassica'' in Europe) is an American documentary television series that aired on The Learning Channel from 1994 to 1999. The series focused on paleontology and comprised 50 half-hour episodes spread over four seasons. It was the first multi-season television series dedicated to paleontology. Clips from the series were frequently used within other paleontology programs aired by the Discovery Channel and other channels owned by the Discovery Network. Reception Season 1 (1994) featured a smooth style and was narrated by Ben Gazzara. This series had many musical scenes, and some considered the show calm and relaxing; it also used much more paleoart than later series. Season 2 (1995) and Season 3 (1996) lost the musical element (as well as changing the narrator to Nick Schatzki), which resulted in a more conventional-style nature documentary. Even so, Seasons 2 and 3 were still perceived as maintaining the quality standard. For Season 4 ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deinonychus
''Deinonychus'' ( ; ) is a genus of Dromaeosauridae, dromaeosaurid Theropoda, theropod dinosaur with one described species, ''Deinonychus antirrhopus''. This species, which could grow up to long, lived during the early Cretaceous Period (geology), Period, about 115–108 million years ago (from the mid-Aptian to early Albian Stage (stratigraphy), stages). Fossils have been recovered from the U.S. states of Montana, Utah, Wyoming, and Oklahoma, in rocks of the Cloverly Formation and Antlers Formation, though teeth that may belong to ''Deinonychus'' have been found much farther east in Maryland. Paleontology, Paleontologist John Ostrom's study of ''Deinonychus'' in the late 1960s revolutionized the way scientists thought about dinosaurs, leading to the "dinosaur renaissance" and igniting the debate on whether dinosaurs were endotherm, warm-blooded or ectotherm, cold-blooded. Before this, the popular conception of dinosaurs had been one of plodding, reptile, reptilian gian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryolophosaurus
''Cryolophosaurus'' ( or ; ) is a genus of large theropod dinosaur known from only a single species, ''Cryolophosaurus ellioti'', from the Early Jurassic of Antarctica. It was one of the largest theropods of the Early Jurassic, with the subadult, being estimated to have reached long and weighed . ''Cryolophosaurus'' was first excavated from Antarctica's Early Jurassic, Pliensbachian aged Hanson Formation, formerly the upper Falla Formation, by paleontologist Dr. William Hammer in 1991. It was the first carnivorous dinosaur to be discovered in Antarctica, and the first non-avian dinosaur from the continent to be officially named. The sediments in which its fossils were found have been dated at ~196 to 188 million years ago, representing the Early Jurassic Period. ''Cryolophosaurus'' is known from a skull, a femur and other material, all of which have caused its classification to vary greatly. The femur possesses many primitive characteristics that have classified ''Cryolophos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnotaurus
''Carnotaurus'' (; ) is a genus of Theropoda, theropod dinosaur that lived in South America during the Late Cretaceous period, probably sometime between 72 and 69 million years ago. The only species is ''Carnotaurus sastrei''. Known from a single well-preserved skeleton, it is one of the best-understood theropods from the Southern Hemisphere. The skeleton, found in 1984, was uncovered in the Chubut Province of Argentina from rocks of the La Colonia Formation. ''Carnotaurus'' is a derived member of the Abelisauridae, a group of large theropods that occupied the large predation, predatorial ecological niche, niche in the southern landmasses of Gondwana during the late Cretaceous. Within the Abelisauridae, the genus is often considered a member of the Brachyrostra, a clade of short-snouted forms restricted to South America. ''Carnotaurus'' was a lightly built, bipedal predator, measuring in length and weighing . As a theropod, ''Carnotaurus'' was highly specialized and distincti ...

Seismosaurus
''Diplodocus'' (, , or ) is an extinct genus of diplodocid sauropod dinosaurs known from the Late Jurassic of North America. The first fossils of ''Diplodocus'' were discovered in 1877 by S. W. Williston. The generic name, coined by Othniel Charles Marsh in 1878, is a Neo-Latin term derived from Greek διπλός (''diplos'') "double" and δοκός (''dokos'') "beam", in reference to the double-beamed chevron bones located in the underside of the tail, which were then considered unique. The genus of dinosaurs lived in what is now mid-western North America, at the end of the Jurassic period. It is one of the more common dinosaur fossils found in the middle to upper Morrison Formation, with most specimens being found in rocks between about 151.88 and 149.1 million years ago , during the latest Kimmeridgian Age, although it may have made it into the Tithonian., with at least one specimen (AMNH FR 223) being potentially from among the youngest deposits of the formation.

Triceratops
''Triceratops'' ( ; ) is a genus of Chasmosaurinae, chasmosaurine Ceratopsia, ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous Period (geology), period, about 68 to 66 million years ago on the island continent of Laramidia, now forming western North America. It was one of the last-known non-avian dinosaurs and lived until the Cretaceous-Paleogene extinction event, Cretaceous–Paleogene extinction event 66 million years ago. The name ''Triceratops'', which means 'three-horned face', is derived from the Ancient Greek, Greek words () meaning 'three', () meaning 'horn', and () meaning 'face'. Bearing a large bony neck frill, frill, three horns on the skull, and a large, four-legged body, exhibiting convergent evolution with bovines and rhinoceroses, ''Triceratops'' is one of the most recognizable of all dinosaurs and the best-known ceratopsian. It was also one of the largest, measuring around long and weighing up to . It shared the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ankylosaurs
Ankylosauria is a group of herbivorous dinosaurs of the clade Ornithischia. It includes the great majority of dinosaurs with Armour (zoology), armor in the form of bony osteoderms, similar to turtles. Ankylosaurs were bulky quadrupeds, with short, powerful limbs. They are known to have first appeared in North Africa during the Middle Jurassic, and persisted until the end of the Late Cretaceous. The two main families of ankylosaurians, Nodosauridae and Ankylosauridae primarily originated from the Northern Hemisphere (North America, Europe and Asia), but the more basal Parankylosauria originated from southern Gondwana (South America, Australia and Antarctica) during the Cretaceous. Ankylosauria was first named by Henry Fairfield Osborn in 1923.Osborn, H. F. (1923). "Two Lower Cretaceous dinosaurs of Mongolia." ''American Museum Novitates'', 95: 1–1/ref> In the Linnaean classification system, the group is usually considered either a suborder or an infraorder. It is contained within ...

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] |
Carnosaurs
Carnosauria is an extinct group of carnivorous theropod dinosaurs that lived during the Jurassic and Cretaceous periods. While Carnosauria was historically considered largely synonymous with Allosauroidea, some recent studies have revived Carnosauria as clade including both Allosauroidea and Megalosauroidea (which is sometimes recovered as paraphyletic with respect to Allosauroidea), and thus including the majority of non-coelurosaurian members of theropod clade Tetanurae. Other researchers have found Allosauroidea and Megalosauroidea to be unrelated groups.Cau A. (2024)A Unified Framework for Predatory Dinosaur Macroevolution Bollettino della Società Paleontologica Italiana, 63(1): 1-19. Distinctive characteristics of carnosaurs include large eye sockets, a long narrow skull and modifications of the legs and pelvis such as the thigh (femur) being longer than the shin (tibia). Carnosaurs first appeared in the Middle Jurassic around , and the last definitive carnosaur family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ghost Ranch
Ghost Ranch is a retreat and education center in Rio Arriba County in north central New Mexico, United States. It is about 65 miles northwest of Santa Fe and 14 miles from Abiquiu, the nearest community. In the later 20th century, it was the summer home and studio of artist Georgia O'Keeffe, as well as the subject of many of her paintings. It often serves as a location for movie production. Ghost Ranch is owned by the Presbyterian Church (USA) and leased to and managed by The National Ghost Ranch Foundation, Inc. Ghost Ranch is known for a remarkable concentration of fossils, most notably that of the theropod dinosaur ''Coelophysis'', of which it has been estimated that nearly a thousand individuals have been preserved in a quarry at Ghost Ranch. History Ghost Ranch is part of Piedra Lumbre (Spanish, "Shining Rock"), a 1766 land grant to Pedro Martin Serrano from King Charles III of Spain. The Rito del Yeso is a stream that meanders through the canyons and gorge, providi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valle De La Luna (Argentina)
Ischigualasto Provincial Park (), also called ''Valle de la Luna'' ("Valley of the Moon" or "Moon Valley"), due to its moon-like appearance, is a provincial protected area in the north-east of San Juan Province, north-western Argentina, limiting to the north with the Talampaya National Park, in La Rioja Province. Both areas belong to the same geological formation, the Ischigualasto Formation (sometimes called the Ischigualasto-Talampaya Formation). Established on 3 November 1971, the park has an area of . In 2000, UNESCO included Ischigualasto and Talampaya National Park among its World Heritage Sites. History The name Ischigualasto is derived from the extinct Cacán language, spoken by an indigenous group referred to as the Diaguita by the Spanish conquistadors and means "place where the moon alights". Another hypothesis gives the name "Ischigualasto" a Quechua origin, meaning "dead land", although some scholars have proposed Huarpe roots. The first paleontological descri ...

Cerritosauridae
Proterochampsia is a clade of early archosauriform reptiles from the Triassic period. It includes the Proterochampsidae (e.g. ''Proterochampsa'', '' Chanaresuchus'' and '' Tropidosuchus'') and probably also the Doswelliidae. Nesbitt (2011) defines Proterochampsia as a stem-based taxon that includes '' Proterochampsa barrionuevoi'' and all forms more closely related to it than ''Euparkeria capensis'', ''Erythrosuchus africanus'', ''Passer domesticus'' (the House Sparrow), or ''Crocodylus niloticus'' (the Nile crocodile). Therefore, the inclusion of Doswelliidae in it is dependent upon whether '' Doswellia'' and ''Proterochampsa'' form a monophyletic group to the exclusion of Archosauria and other related groups. Description Nesbitt (2011) found that Proterochampsians share several distinguishing characteristics, or synapomorphies. A prominent ridge runs along the length of the jugal, a bone below the eye. Another ridge is present on the quadratojugal, a bone positioned toward th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
