The Dinosaurs or Dinosauria, is the name of a group of archosaurian reptiles that lived from the Mid Triassic Period (230 mya) to today. Dinosaurs are arguably the most famous creatures ever to live on earth, first described as a group by anatomist Sir Richard Owen during a lecture in 1841, based on three genera, Megalosaurus, Iguanodon, and Hylaeosaurus. Dinosaurs now includes over a thousand species, hundreds of taxon, and around thirty families (excluding birds). Dinosaurs gained a huge popularity boost in 1993, with the release of the original Jurassic Park, and subsequent sequels every four years, with the exception of the fourth movie. The only dinosaurs left alive today are the sole theropod family to survive the Cretaceous extinction, the birds. Crocodilians are the only sister group alive of the dinosaurs. The closest extinct group were the pterosaurs. The word dinosaur itself derives from the Greek and means "terrible lizard". Despite this name, dinosaurs are not nor are closely related to lizards; and in fact many of them had some degree of feathers.
In the 1980s InGen managed to successfully clone dinosaurs from preserved DNA in fossilized amber. There is some debate regarding whether or not dinosaurs were warm or cold blooded, however the Jurassic World website lists carnivores as being warm blooded and herbivores and being cold blooded.
The term "dinosaur" is also popularly applied to many prehistoric animals that are not taxonomically classified as such, including prehistoric crocodiles, mosasaurs, ichthyosaurs, plesiosaurs and pliosaurs, pterosaurs, and synapsids such as Dimetrodon. This is frowned upon in scientific writing, but persists in the media and in everyday speech.
