 According to Michael Crichton (qv)s Jurassic Park novels, Sarah  Harding is the daughter of Gerry Harding, the vet who treated the  sick triceratops in the first film. In the book, Sarah was a  zoologist, not a paleontologist; the paleontologist who Malcolm went  to Isla Sorna to save was a man named Richard Levine, a character  who only made it to the film as certain aspects of the Sarah  character.
