Ian Malcolm‘s girlfriend, a paleontologist specializing in the parental behavior of dinosaurs, particularly Tyrannosaurus. Dr. Sarah Harding first met Ian when he’d heard rumors about the incident at Isla Nublar, and came down to the hospital in Costa Rica where he had been sent to recover from his injuries so that she could ask him if the rumors were true. After he fully recovered, they started dating. Sarah had theorized that tyrannosaurs were caring, attentive parents, as opposed to Robert Burke‘s theory that they would abandon their young at early ages. Sarah immediately volunteered when she heard that John Hammond needed a paleontologist for his research team to Isla Sorna, and even left before the rest of the team so that Ian couldn’t stop her from going. Knowing about his past experiences, she was surprised when Ian arrived on the island with Eddie Carr and Nick van Owen. While she was thankful that he had come to “rescue” her, she told him as politely as possible that she didn’t need rescuing and could handle herself. After an infant Tyrannosaurus was injured by Peter Ludlow, Sarah and Nick brought it back to the trailer, though it had been Nick’s idea to do so. They fixed its leg, but the infant’s parents showed up shortly thereafter looking for their offspring, confirming Sarah’s theory about their parenting behaviors. Later on, blood from the baby rex that had stained Sarah’s jacket attracted the parents once more, which ultimately resulted in the deaths of most of the hunters and nearly her own. When the bull tyrannosaur was brought back to San Diego by Ludlow, it was Sarah who finally tranquilized him so that he and the baby tyrannosaur could be safely returned to Isla Sorna.
