A hill in southeastern Bolivia is home to over 5,000 fossilised dinosaur tracks.
Cal Orcko, on the outskirts of Sucre in Bolivia, is one of the biggest sites for fossilised footprints ever found.
The location is a huge draw for tourists, welcoming some 1,20,000 visitors a year.
Some 65 million years ago, the land in the area was muddy and flat.
With the passing of time, "movements of tectonic plates, skid plates and marine continents" beneath the surface pushed the ground into its nearly upright position, while the mud also dried into limestone.
The footprints were first discovered in the mid-1990s, when rain and erosion uncovered them. Another part was discovered when the cement factory started exploiting the nearby quarry.
Rediff.com presents the terrifying T-Rex footprints and the massive titanosaurs that stun visitors from around the world.
