Bolivian farmer Primo Rivera stands in an area called Tunasniyoj, which means "the place of the prickly pear cactus," where he made a new discovery of dinosaur footprints near Icla, 155 km (96 miles) southeast of Sucre, November 16, 2008. This new discovery, which complements two other world famous dinosaur footprint sites in the same province, is twice as old as the others, dated by Argentine paleontologists at 144 million years old, and contains some 300 footprints from two types of dinosaurs, carnivorous theropod and ankylosaurus.
