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? Youll have to scroll down to find out.
Cal Orko: A Paleontologists Dream Inside a Quarry
Believe it or not, Cal Orko is situated entirely within a limestone quarry owned by FANCESA, Bolivias National Cement Factory. Located in the El Molino formation, the sight of heavy mining machinery (one could argue they are todays land giants) set against a backdrop of 68 million-year-old dinosaur footprints (Earths 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. Its from this vantage point that you truly grasp the sheer scale and magnitude of Cal Orko.

Ahh, those were the days.

(51,004 posts)No matter how many times you tell the dinosaurs to wipe their feet, do they do it??? No! And they track footprints all over the wall. I mean, the triceratops at least tries to remember, but he's so stupid, he just can't get it right. But the stegosaurus? NO excuse!
But otherwise, this is very, very cool.

(39,909 posts)We had footprints on OUR wall after the Millennium New Years Party.
We'll have to clean those off one of these days.
At least we clean up our mess.....eventually.
