"Dinosaur tracks are the nearest thing we have to dinosaur motion pictures," one expert has said. Tracks are dynamic evidence, the record in stone of a moment that passed into history as long as 200 million years ago. Perhaps more than any other kind of fossil, footprints evoke the walking, running, living and breathing animals of the past.
Dinosaur trackers, like detectives at an ancient crime scene, study these prints for clues to behavior. Did some dinosaurs move in herds, like elephants, with the biggest animals in the lead? Did they migrate long distances in search of food? Did some species hunt alone? The track record may hold the answer.
