A quarry, located near the Bolivian capital of Sucre, is the most important archaeological site with evidence of dinosaurs in the world, the place is known by locals as the Cal Orko.
With more than 68 million years ago, thousands of dinosaurs gathered in Cal Orko region – the lake in those days – in search of food and water. This explains the huge influx of over 5,000 dinosaur footprints located in more than 350 cross paths on a crumbling wall. The most amazing thing is that Cal Orko traces the steps from 330 different species of dinosaurs in the Cretaceous, just before disappearing.
Unfortunately, the wall facing constant danger of damage, and the authorities in Bolivia spend 30 million dollars annually to keep whole. With every effort, however, part of the dinosaur wall crumbled earlier this month, about 300 are permanently losing marks.
