The Jurassic Park Logo is a collective term used for the various logos seen in the novels and films. The logo was designed by Sandy Collora after the skeleton that appeared on every cover of the book and first appeared in Jurassic Park, where they were seen all over the park's merchandise. The logo soon became so distinctive and well-known that the sequels (which focused on a different island, Isla Sorna, which was not the site of the theme park and therefore had no logos) had new logos designed that were used on posters and official film-related merchandise. There have also been video games that unique logos have been specifically designed for.
