Paleontologist Sebastian Apesteguia measures the footprint made by a meat-eating predator some 80 million years ago and one of the largest of its kind ever found, at the Maragua Syncline, Bolivia, July 21, 2016. The print, which measures 1.2 meters (1.3 yards) across, probably belonged to the abelisaurus, a biped dinosaur that once roamed South America, said Argentine paleontologist Sebastian Apesteguia, who is studying the find.
