Bringing dinosaurs back to life – with fossil footprints
Dinosaur tracks can teach us more about the day-to-day behavior of creatures like T. Rex or the Stegosaurus than their skeletons ever could, says paleontologist Martin Lockley. From a "dinosaur's lover's lane" in Colorado, where the ancestors of today's birds clawed out giant nests to attract mates, to the rocky shores of South Korea, where scientists have discovered footprints of tiny birds besides tracks of 100-ft-long brontosaurs, Lockley interprets the traces of some of the most impressive creatures ever to walk the earth.
