Go to the part in the movie where they are about to be rescued and taken back to San Diego. Go to the part when the raptors chased Sarah and Ian's daughter into the room. The raptors are trying to dig in the room they are in, and they are trying to dig out the other side. The raptors are getting so close they can fit their head under the door. Later, Ian enters the room, and there is no hole under the door at all. The hole has disappeared!
