Located 5 km (3 miles) from downtown Sucre, Bolivia is Cal Orko, an imposing limestone slab 1.5 km (0.9 miles) long and over 100 meters high (328 ft). On this steep face (inclination of 72 degrees), visitors can peer through time to when dinosaurs roamed the Earth over 68 million years ago.
At Cal Orko you will find 462 distinct dinosaur tracks from at least 8 different species, totaling an incredible 5,055 individual dinosaur footprints. So how do thousands of dinosaur footprints come to be, on a seemingly vertical rock face hundreds of feet high? You’ll have to scroll down to find out.
Believe it or not, Cal Orko is situated entirely within a limestone quarry owned by FANCESA, Bolivia’s National Cement Factory. Located in the ‘El Molino’ formation, the sight of heavy mining machinery (one could argue they are today’s ‘land giants’) set against a backdrop of 68 million-year-old dinosaur footprints (Earth’s prehistoric ‘land giants’) creates an intriguing parallel.
Further up the hill is Parque Cretácico. Opened in 2006, the dinosaur museum features 24 life-sized dinosaur replicas, various exhibitions, and a viewing platform 150 meters (~500 ft) from the rock face. It’s from this vantage point that you truly grasp the sheer scale and magnitude of Cal Orko.
So Dinosaurs Can Climb Walls Now?
Not quite. We’re looking at something 68 million years in the making. The footprints at this site were formed during the Maastrichtian age of the Cretaceous Period in the Mesozoic Era. As Ian Belcher of The Guardian explains:
“It was unique climate fluctuations that made the region a palaeontological honey pot. The creatures’ feet sank into the soft shoreline in warm damp weather, leaving marks that were solidified by later periods of drought. Wet weather then returned, sealing the prints below mud and sediment. The wet-dry pattern was repeated seven times, preserving multiple layers of prints. The cherry on the cake was added when tectonic activity pushed the flat ground up to a brilliant viewing angle – as if nature was aware of its tourism potential.”
