Since we can't watch the extinct animals walking or running, scientists use living animals as models to measure how long it takes them to step. In 2006, Kent Stevens from the University of Oregon did an experiment inspired by that very scene to figure out what sort of binocular range (the field of view both eyes can see simultaneously) T. rex might have had. He said he thinks T. rex's puny arms were vestigial a body part or organ that no longer serves a function but is nevertheless retained (kind of like a human's appendix or wisdom teeth).
