Dinosaur

Dinosaurs are a diverse group of warmblooded reptiles of the clade Dinosauria. They existed through most of the Mesozoic era, first appearing early in the Triassic period. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya and their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds.

Dinosaur (2000 film)

Dinosaur is a 2000 American adventure film directed by Ralph Zondag and Eric Leighton and written by John Harrison, Robert Nelson Jacobs, and Walon Green. Produced by Walt Disney Feature Animation and The Secret Lab, the live-action animated film stars the voices of D. B. Sweeney, Alfre Woodard, Ossie Davis, Max Casella, Hayden Panettiere, Samuel E. Wright, Julianna Margulies, Peter Siragusa, Joan Plowright, and Della Reese. The film follows a young Iguanodon named Aladar (Sweeney) who was adopted and raised by a family of lemurs on a tropical island. They are forced to the mainland by a catastrophic meteorite impact; setting out to find a new home, they join a herd of dinosaurs heading for the "Nesting Grounds", but must contend with the group's harsh leader, as well as external dangers such as predatory Carnotaurus.
