Although the first "Jurassic Park" film was released in 1993, the book which inspired it was written by Michael Crichton in 1990, according to the author's website. It is also noted that Crichton started writing the early stages of the story in 1983 and worked on it for several years before its completion.
In a Variety interview with paleontologist Jim Kirkland, the scientist explained some basic inaccuracies regarding Velociraptors in the film. Kirkland said, "There had been a book that lumped Deinonychus into Velociraptor, which is stupid." The book that caused these problems is Gregory S. Paul's "Predatory Dinosaurs of the World." According to Kirkland, Michael Crichton used this 1988 book while researching the novel.
Considering these comments, it seems as if Crichton based the information in his book on incorrect facts, which then extended into the film series. This means that the name Velociraptor is used while depicting an entirely different species.
