It is speculated that this incorrect portrayal came about because of mislabelling of Deinonychus as a subspecies of Velociraptor in the 1988 American book, Predatory Dinosaurs of the World, whose author, Gregory Paul, is credited as an inspiration by Crichton at the end of his first novel. Size-wise, and in terms of its large sickle-shaped talons on each foot, the dinosaur in the film is more like Velociraptor's larger dromaeosaurid cousin, Deinonychus (although it too was a feathered theropod). A star was born (Velociraptor, not Neill) - but the portrayal was inaccurate, both in terms of size (in reality, Velociraptor stood barely half a metre high), and its lack of feathers ('quill knobs' proving that Velociraptor was feathered were overlooked until 2007 when they were discovered on the forelimb). Known simply as 'raptors' in the film, Velociraptor was portrayed as a person-sized, terrifyingly fast and vicious predator that tormented the unfortunate Sam Neill and his Hollywood co-stars. However, the fearsome impression people have of it now does not tally with reality. rex, Stegosaurus and Triceratops, plus less well known species including Maiasaura and Dilophosaurus (the majority of these dinosaurs lived in the Cretaceous period, despite the story's title).īut the dinosaur which gained the biggest publicity boost from Spielberg's film was Velociraptor, a Late Cretaceous theropod first discovered in the Gobi desert in 1922. Fifteen different species appeared in the first novel (Crichton published a sequel in 1995), including old favourites such as T. In the process, stars were made of a host of dinosaurs. Based on the 1990 novel by the late Michael Crichton, Steven Spielberg's Oscar-winning epic three years later envisaged an amusement park stocked with dinosaurs brought back to life by the wonders of genetic cloning. N o film has influenced popular understanding of dinosaurs more than Jurassic Park.
