Jurassic Park Conflicts

When I first heard that we were going to be watching Jurassic Park, I was ecstatic since I never expected to watch movies in a college class, and I enjoyed watching the movies when I was younger and actually had the time to watch tv and movies!  I think it is an interesting movie, but just because of the suspense.  I knew that a lot of the so-called "facts" in the movie aren't real, but there were just some things that I never knew until I read the Jurassic Park article from Past Imperfect.  For instance, I didn't know that the word raptor originated from a Latin term (rapere) meaning to take by force, not bird of prey, as stated in the movie.  Also, if most of the dinosaurs were from the Cretaceous period, which came after the Jurassic period, why didn't he just call it Cretaceous Park?  But the only reason Crichton used a T-Rex (also a Cretaceous period dinosaur) on the cover of his book was simply because he thought it looked good when viewing different graphics options.  As an author, he should know better since you shouldn't judge a book by its cover.  So now I have relearned once again that my mom was always right in telling me not to believe everything I hear (even if it does seen scientific and factual).  Note to self - always do my research!  Thanks, Mom!
