A Paleontologist can tell from fossil footprints of a dinosaur what types of dinosaurs traveled in large groups or herds. Sets of tracks also show that some herds protected their young by keeping them in the centers of migrating groups. Other tracks show that dinosaurs did not drag their tails when they walked. Paleontologists can also estimate dinosaur gait and speed from some footprint track ways. If the footprints are close together, this might show they were running. If the footprints are spaced farther apart, the dinosaurs may have been walking.
