Nestled on the outskirts of Sucre, Bolivia, the Cal Orck’o dinosaur track site stands as one of the most extraordinary paleontological discoveries in the world. This natural marvel, often referred to as the "dinosaur dance floor," is a testament to the incredible biodiversity and geological history of our planet. The site offers a rare glimpse into the prehistoric past, preserving thousands of footprints that date back approximately 68 million years.

The Geological Wonder of Cal Orck’o

Cal Orck’o is not just remarkable for its paleontological significance but also for its sheer geological grandeur. The site is a massive vertical limestone wall that stretches nearly a mile (1.5 kilometers) in length and towers over 100 meters high. The wall’s steep inclination of 72 degrees showcases the raw power of tectonic forces that have shaped the earth over millions of years. Originally, this surface would have been a flat, muddy plain, part of a sprawling coastal environment where dinosaurs roamed freely. Over time, the movement of tectonic plates and the uplifting of the Andes turned this once-horizontal surface into a vertical wall, preserving the footprints of these ancient creatures as a snapshot of life during the late Cretaceous period.

An Impressive Collection of Dinosaur Tracks

What makes Cal Orck’o truly unique is the sheer number and diversity of dinosaur footprints embedded within its limestone face. The site boasts more than 5,000 individual footprints, arranged in 462 distinct tracks, which were left by at least eight different species of dinosaurs. These tracks tell the story of a thriving ecosystem, offering evidence of interactions between different dinosaur species as they traversed the prehistoric landscape.

Among the species identified at Cal Orck’o are the fearsome theropods, which include large carnivorous dinosaurs like Tyrannosaurus rex. There are also the tracks of smaller, nimble predators, possibly raptors, as well as the distinctive, broad prints of herbivorous sauropods, the long-necked giants of the dinosaur world. One of the most remarkable tracks at the site extends over 300 meters in length, suggesting that the dinosaur which made it was not only enormous but also traveled a significant distance across the ancient plain.

The Legacy of the Dinosaur Footprints

The footprints at Cal Orck’o offer invaluable insights into the behavior, movement, and interaction of dinosaurs. For instance, some tracks suggest herding behavior among sauropods, while others show evidence of solitary hunting by theropods. The diversity of tracks also indicates a rich and varied ecosystem, with different species coexisting and possibly competing for resources.

One of the most fascinating aspects of these tracks is the way they have been preserved. The muddy plains that once existed here were periodically covered by layers of sediment, which protected the footprints from erosion and fossilized them over time. As the landscape continued to change, these layers were compressed into limestone, preserving the footprints in remarkable detail.

The Discovery and Study of Cal Orck’o

The existence of the dinosaur tracks at Cal Orck’o was first brought to global attention in the mid-1990s, during the operations of a local cement company. As workers quarried the limestone, they began to notice the unusual indentations on the rock face. Paleontologists quickly realized the significance of the find, and since then, the site has been the subject of extensive study.

Numerous experts have visited Cal Orck’o to analyze the tracks, and it has also become a popular destination for tourists and dinosaur enthusiasts. The site is now protected and managed as part of the Parque Cretácico (Cretaceous Park), a museum and visitor center that offers guided tours and educational exhibits. The park plays a crucial role in preserving the site and educating the public about the importance of paleontology.

Capturing Cal Orck’o: The Photographers

The breathtaking scale and beauty of Cal Orck’o have attracted photographers from around the world, who have sought to capture the essence of this prehistoric landscape. Among them are Jerry Daykin, Ramon Kristian Arellano, Pete Oxford, and Carsten Drossel, each of whom has contributed to documenting the site’s majesty.

These photographers have captured stunning images that showcase the sheer size of the wall and the intricate detail of the dinosaur tracks. Their work has been instrumental in raising awareness about Cal Orck’o and its significance, helping to bring the wonder of this site to a global audience.

A Window into the Past

Cal Orck’o is more than just a collection of dinosaur tracks—it is a window into a world that existed millions of years before humans walked the earth. This site offers a rare opportunity to see the footprints of creatures that once dominated the planet, preserved in stone for eternity. As one of the most spectacular locations of its kind in the world, Cal Orck’o continues to captivate scientists, photographers, and visitors alike, reminding us of the incredible history written in the rocks beneath our feet.
