When they all climb the latter near the end of the movie to get in the ceiling before the raptor gets them, the raptor pops up briefly before he gets a few swift kicks to the face. At the same time the little girl is on top of the same ceiling tile the raptor lifts up. So when he falls down and the girl almost goes with him, the girl looks up and if you pay very close attention you can tell that was the double of the little girl, and in a show called "The Making of Jurassic Park," the staff members even said so themselves.
