In 1993, four years after the disaster at Jurassic Park, chaos theorist and mathematician Ian Malcolm – who is revealed to have survived the events of the previous novel, despite being declared dead in the epilogue – teams up with paleontologist Richard Levine to search for a "lost world" of dinosaurs following rumors of strange animal corpses washing up on the shores of Costa Rica. In 1995, they learn of Site B on Isla Sorna, the "production facility" where the now-defunct company InGen hatched and grew the dinosaurs for their Jurassic Park theme park on nearby Isla Nublar.
