The Dinosaurs!
''The Dinosaurs!'' is an American television miniseries produced by WHYY-TV for PBS in 1992, featuring some of the then-modern theories about dinosaurs and how they lived. It aired four episodes from November 22 to November 25, 1992. The program The program features the age of dinosaurs, from the appearing of the early forms like ''Herrerasaurus'', to the ''Tyrannosaurus'' and Ceratopsians of the late Cretaceous. The possibilities whether dinosaurs were active, warm-blooded animals, had parental care, and the theory that they are the ancestors to birds are featured. What caused their extinction is also discussed.

Documentary Film
A documentary film (often described simply as a documentary) is a nonfiction Film, motion picture intended to "document reality, primarily for instruction, education or maintaining a Recorded history, historical record". The American author and Media studies, media analyst Bill Nichols (film critic), Bill Nichols has characterized the documentary in terms of "a filmmaking practice, a cinematic tradition, and mode of audience reception [that remains] a practice without clear boundaries". Research into information gathering, as a behavior, and the sharing of knowledge, as a concept, has noted how documentary movies were preceded by the notable practice of documentary photography. This has involved the use of singular Photograph, photographs to detail the complex attributes of History, historical events and continues to a certain degree to this day, with an example being the War photography, conflict-related photography achieved by popular figures such as Mathew Brady during the Am ...

Archelon
''Archelon'' is an extinct marine turtle from the Late Cretaceous, and is the largest turtle ever to have been documented, with the biggest specimen measuring from head to tail and in body mass. It is known only from the Pierre Shale and has one species, ''A. ischyros''. In the past, the genus also contained ''A. marshii'' and ''A. copei'', though these have been reassigned to ''Protostega'' and ''Kansastega'', respectively. The genus was named in 1896 by American paleontologist George Reber Wieland based on a skeleton from South Dakota, who placed it into the extinct family (biology), family Protostegidae. The leatherback sea turtle (''Dermochelys coriacea'') was once thought to be its closest living relative, but now, Protostegidae is thought to be a completely separate lineage from any living sea turtle. ''Archelon'' had a leathery carapace instead of the hard shell seen in most sea turtles. The carapace may have featured a row of small ridges, each peaking at in heigh ...

Coelophysis
''Coelophysis'' ( Traditional English pronunciation of Latin, traditionally; or , as heard more commonly in recent decades) is a genus of coelophysid Theropoda, theropod dinosaur that lived Approximation, approximately 215 to 201.4 million years ago during the Late Triassic Period (geology), period from the middle Norian to Rhaetian age in what is now the southwestern United States. ''Megapnosaurus'' was once considered to be a species within this genus, but this interpretation has been challenged and the genus ''Megapnosaurus'' is now considered valid. ''Coelophysis'' was a small, slenderly built, ground-dwelling, bipedal carnivore that could grow up to long. It is one of the earliest known dinosaur genera. Scattered material representing similar animals has been found worldwide in some Late Triassic and Early Jurassic formations. The type species ''C. bauri'', originally given to the genus ''Coelurus'' by Edward Drinker Cope in 1887, was described by the latter in 1889. T ...

Coelacanth
Coelacanths ( ) are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. As sarcopterygians, they are more closely related to lungfish and tetrapods (the terrestrial vertebrates including living amphibians, reptiles, birds and mammals) than to ray-finned fish. The name coelacanth originates from the Permian genus '' Coelacanthus'', which was the first scientifically named genus of coelacanths (in 1839), becoming the type genus of Coelacanthiformes as other species were discovered and named. Well-represented in freshwater and marine deposits from as early as the Devonian period (more than 410million years ago), they were thought to have become extinct in the Late Cretaceous, around 66million years ago. The first living species, ''Latimeria chalumnae'', the West Indian Ocean coelacanth, was described from specimens fished off the coast of South Africa from 1938 onward; they are now also known to inhabit the seas around the Comoro Islands off the eas ...

Chirostenotes
''Chirostenotes'' ( ; named from Ancient Greek, Greek 'narrow-handed') is a genus of oviraptorosaurian dinosaur from the late Cretaceous (about 76.5–75 million years ago) of Alberta, Canada. The type species is ''Chirostenotes pergracilis''. History of discovery ''Chirostenotes'' has a confusing history of discovery and naming. The first fossils of ''Chirostenotes'', a pair of hands, were in 1914 found by George Fryer Sternberg near Little Sandhill Creek in the Campanian Dinosaur Park Formation of Canada, which has yielded the most dinosaurs of any Canadian formation. The specimens were studied by Lawrence Morris Lambe who, however, died before being able to formally name them. In 1924, Charles Whitney Gilmore adopted the name he found in Lambe's notes and described and named the type species ''Chirostenotes pergracilis''. The generic name is derived from Greek ''cheir'', "hand", and ''stenotes'', "narrowness". The specific name (zoology), specific name means "throughout", ''p ...

Ceratosaurus
''Ceratosaurus'' (from Greek 'horn' and 'lizard') is a genus of carnivorous theropod dinosaur that lived in the Late Jurassic period (Kimmeridgian to Tithonian ages). The genus was first described in 1884 by American paleontologist Othniel Charles Marsh based on a nearly complete skeleton discovered in Garden Park, Colorado, in rocks belonging to the Morrison Formation. The type species is ''Ceratosaurus nasicornis''. The Garden Park specimen remains the most complete skeleton known from the genus and only a handful of additional specimens have been described since. Two additional species, ''Ceratosaurus dentisulcatus'' and ''Ceratosaurus magnicornis'', were described in 2000 from two fragmentary skeletons from the Cleveland-Lloyd Quarry of Utah and from the vicinity of Fruita, Colorado. The validity of these additional species has been questioned, however, and all three skeletons possibly represent different growth stages of the same species. In 1999, the discovery o ...

Centrosaurus
''Centrosaurus'' ( ; ) is a genus of centrosaurine ceratopsian dinosaur from Campanian age of Late Cretaceous Canada. Their remains have been found in the Dinosaur Park Formation, dating from 76.5 to 75.5 million years ago. Discovery and naming The first ''Centrosaurus'' remains were discovered and named by paleontologist Lawrence Lambe in strata along the Red Deer River in Alberta. The name ''Centrosaurus'' means "pointed lizard" (from Greek ', , "point" and ', , "lizard") and refers to, the series of small hornlets placed along the margin of their frills, not the nasal horns (which were unknown when the dinosaur was named). The genus is not to be confused with the stegosaur ''Kentrosaurus'', the name of which is derived from the same Greek word. Later, vast bonebeds of ''Centrosaurus'' were found in Dinosaur Provincial Park, also in Alberta. Some of these beds extend for hundreds of meters and contain thousands of individuals of all ages and all levels of completion. Sc ...

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 ...

Camptosaurus
''Camptosaurus'' ( ) is a genus of plant-eating, beaked ornithischian dinosaurs of the Late Jurassic Period (geology), period of western North America and possibly also Europe. The name means 'flexible lizard' (Ancient Greek, Greek (') meaning 'bent' and (') meaning 'lizard'). History of discovery On September 4, 1879 William Harlow Reed in Albany County, Wyoming found the remains of a small Euornithopoda, euornithopod. That same year Professor Othniel Charles Marsh described and named the find as ''Camptonotus'', or "flexible back", from Greek κάμπτω, "to bend" and νῶτον, "back", in reference to the presumed flexibility of the sacral vertebrae. The holotype was YPM 1877, a partial skeleton. The genus was renamed ''Camptosaurus'' by him in 1885 because the original name was already in use for a cricket (insect), cricket. In 1879, Marsh named ''C. dispar'' (type species of the genus) for material he received from his collectors at ''Quarry 13'' near Como Bluff, Wyom ...

Camarasaurus
''Camarasaurus'' ( ) is a genus of sauropod dinosaur that lived in North America during the Late Jurassic period. Its fossil remains have been found in the Morrison Formation, dating to the Kimmeridgian and Tithonian ages of the Jurassic, between 155 and 145 million years ago (mya). ''Camarasaurus'' presented a distinctive cranial profile of a blunt snout and an arched skull that was remarkably square, typical of basal macronarians. The generic 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 Camaras ...

Caenagnathus
''Caenagnathus'' ('recent jaw') is a genus of caenagnathid oviraptorosaurian dinosaur from the late Cretaceous period (Campanian stage; ~75 million years ago). It is known from partial remains including lower jaws, a tail vertebra, hand bones, hind limbs, and pelvis, all found in the Dinosaur Park Formation of Alberta, Canada. Description ''Caenagnathus'' measured about long and weighed about . It was a large oviraptorosaurian, with some specimens suggesting it achieved sizes comparable to its relative '' Anzu''. Like ''Anzu'', it had a toothless lower beak that was shallower in depth than those of elmisaurines. It also shared with ''Anzu'' less gracile proportions than those of elmisaurines. Like all oviraptorosaurs, it would most likely have possessed a coat of feathers. Classification This dinosaur has a confusing history. In 1936, a set of jaws (CMN 8776) were found, and later given the name ''Caenagnathus'', meaning 'recent jaw'; they were first thought to be those of ...

Brontosaurus
''Brontosaurus'' (; meaning "thunder lizard" from the Ancient Greek, Greek words , "thunder" and , "lizard") is a genus of herbivorous sauropod dinosaur that lived in present-day United States during the Late Jurassic period. It was described by American paleontologist Othniel Charles Marsh in 1879, the type species being dubbed ''B. excelsus'', based on a partial skeleton lacking a skull found in Como Bluff, Wyoming. In subsequent years, two more species of ''Brontosaurus'' were named: ''B. parvus'' in 1902 and ''B. yahnahpin'' in 1994. ''Brontosaurus'' lived about 156 to 146 million years ago (mya) during the Kimmeridgian and Tithonian ages in the Morrison Formation of what is now Utah and Wyoming. For decades, the animal was thought to have been a Synonym (taxonomy), taxonomic synonym of its close relative ''Apatosaurus'', but a 2015 study by Emmanuel Tschopp and colleagues found it to be distinct. It has seen widespread representation in popular culture, being the archetyp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
