Dinosaur is a 2000 American live-action/ CGI adventure film produced by Walt Disney Feature Animation and The Secret Lab and released by Walt Disney Pictures. It is the 39th Disney animated feature film and Disney's first non- Pixar computer animated feature, though it is not officially labeled as one of the animated classics in the United Kingdom, where The Wild (2006) is included in the canon instead. Originally a stand-alone film, it was not included in the canon until 2008.

The film follows an orphaned iguanodon who, as a friend of the lemurs, after surviving a devastating meteor, are moving out for their new home. Along the way, they befriend and reunite the remaining herd of dinosaurs who are being pursued by predators, such as the Carnotaurus, while on a journey to the "Nesting Grounds".

While the characters in Dinosaur are computer-animated, most of the film's backgrounds are live-action and were filmed on location. A number of backgrounds were found in Canaima National Park in Venezuela; various tepuis and Angel Falls also appear in the film. It is the second film (after Fantasia 2000) produced by Disney Animation Studios to feature computer-generated three-dimensional animation. At officially $127.5 million, it was the most expensive theatrical film release of the year. The film was a financial success, grossing over $349 million worldwide in total box office revenue, becoming the fifth highest-grossing film of 2000.

A dinosaur is a member of a largely extinct group of vertebrates (Dinosauria) which is ancestral to birds.

Dinosaur is the debut studio album by the alternative rock band Dinosaur Jr. It was released in 1985 on Homestead Records. The album exhibits a folkier side of the band than on future releases, but some of the tracks on the album showed off a much heavier, more hardcore punk-based side to the band in songs such as "Does it Float", "Mountain Man", and "Bulbs of Passion".

The album was originally released when the band was still known simply as Dinosaur, before a lawsuit forced the name change to Dinosaur Jr. Therefore, it was originally a self-titled album, but subsequent issues kept the Dinosaur title.

"Dinosaur" is a song by Australian rock band Kisschasy, it is the third single released from their third studio album Seizures.

Dinosaurs are a diverse group of animals of the clade Dinosauria that first appeared during the Triassic period. Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, the current scientific consensus places their origin between 231 and 243 million years ago. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago. Their dominance continued through the Jurassic and Cretaceous periods and ended when the Cretaceous-Paleogene extinction event led to the extinction of most dinosaur groups 66 million years ago.

Until the late 20th century, all groups of dinosaurs were believed to be extinct; however, the fossil record indicates that birds are the modern descendants of feathered dinosaurs, having evolved from theropod ancestors during the Jurassic Period, and are now termed "avian dinosaurs". As such, birds were the only dinosaur lineage to survive the mass extinction event. Throughout the remainder of this article, the term "dinosaur" is sometimes used generically to refer to both the avian and non-avian dinosaurs combined, while at other times it is used to refer to the non-avian dinosaurs specifically, and the avian dinosaurs are sometimes simply referred to as "birds". This article deals primarily with non-avian dinosaurs.

Dinosaurs are a varied group of animals from taxonomic, morphological and ecological standpoints. Birds, at over living species, are the most diverse group of vertebrates besides perciform fish. Using fossil evidence, paleontologists have identified over 500 distinct genera and more than different species of non-avian dinosaurs.

Dinosaurs are represented on every continent by both extant species and fossil remains. Some are herbivorous, others carnivorous. While dinosaurs were ancestrally bipedal, many extinct groups included quadrupedal species, and some were able to shift between these stances. Elaborate display structures such as horns or crests are common to all dinosaur groups, and some extinct groups developed skeletal modifications such as bony armor and spines. Evidence suggests that egg laying and nest building are additional traits shared by all dinosaurs.

While the modern-day surviving lineage of dinosaurs (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs were large-bodied—the largest sauropod dinosaurs are estimated to have reached lengths of and heights of and were the largest land animals of all time. Still, the idea that non-avian dinosaurs were uniformly gigantic is a misconception based in part on preservation bias, as large, sturdy bones are more likely to last until they are fossilized. Many dinosaurs were quite small: Xixianykus, for example, was only about long.

Although the word dinosaur literally means "terrible lizard", the name is something of an etymological misnomer; even though dinosaurs are reptiles, they are not lizards, nor are they descended from them. Instead, dinosaurs, like many extinct forms of reptile sub-groups, did not exhibit characteristics which were traditionally regarded as reptilian, such as a sprawling limb posture or ectothermy (colloquially referred to as "cold-bloodedness"). Additionally, many other prehistoric animals, including mosasaurs, ichthyosaurs, pterosaurs, plesiosaurs, and Dimetrodon, while often popularly conceived of as dinosaurs, are not taxonomically classified as dinosaurs.

Through the first half of the 20th century, before birds were recognized to be dinosaurs, most of the scientific community believed dinosaurs to have been sluggish and cold-blooded. Most research conducted since the 1970s, however, has indicated that all dinosaurs were active animals with elevated metabolisms and numerous adaptations for social interaction.

Since the first dinosaur fossils were recognized in the early 19th century, mounted fossil dinosaur skeletons have been major attractions at museums around the world, and dinosaurs have become an enduring part of world culture. The large sizes of some dinosaur groups, as well as their seemingly monstrous and fantastic nature, have ensured dinosaurs' regular appearance in best-selling books and films, such as Jurassic Park. Persistent public enthusiasm for the animals has resulted in significant funding for dinosaur science, and new discoveries are regularly covered by the media.

Dinosaur (originally named Countdown to Extinction) is a dark ride EMV attraction at Disney's Animal Kingdom in Walt Disney World, Lake Buena Vista, Florida.

In the attraction, guests board vehicles called Time Rovers and are taken on a turbulent journey through the Cretaceous period, featuring prehistoric scenes populated with audio-animatronic dinosaurs. Originally named Countdown to Extinction, the ride's name was later changed to Dinosaur to promote the Disney animated film of the same name, even though the attraction has never contained any explicit references to the film. However, the two dinosaurs most prominently featured in the ride have always been an Iguanodon and Carnotaurus, which were both featured prominently in the film. Scenes from the movie also appear in the pre-show, to help the guests identify the Iguanodon as the film's protagonist, Aladar.

In numerous campaign settings of the Dungeons & Dragons (D&D) fantasy role-playing game, dinosaurs, based upon the actual-life extinct reptiles of prehistoric ages, are present. Some of the dinosaurs used in D&D, such as Triceratops, Tyrannosaurus rex, and Ankylosaurus, are real ones which used to exist on earth. Others, such as the Bloodstriker, Fleshraker and Swindlespitter from the Monster Manual III, though labeled as dinosaurs, are made up, and as such are likely better regarded as monsters. Most D&D settings have a location where dinosaurs are known to dwell, and seeing as they coexist with intelligent races, they are sometimes depicted as tamed, with armored tyrannosaurs being used in battle and raptors used as mounts.

"Dinosaur" (stylized as D.I.N.O.$.A.U.R.) is a song by American recording artist and songwriter Kesha, taken from her debut studio album Animal (2010). The song was written by Kesha in collaboration with Max Martin and Shellback; the latter two also produced the song, while all three are responsible for the instrumentation. The song's conception stems from an encounter Kesha had with an older man that had been hitting on her, which she compared to a prehistoric dinosaur. "Dinosaur" is a dance-pop song that lyrically discusses an older man that is attempting to hit on a younger female, which is ultimately rejected. The song received generally negative reviews from music critics. Upon the release of Animal, "Dinosaur" charted on the South Korea Gaon International Chart, peaking 107 respectively.
