A 66-million-year-old dinosaur highway in Bolivia reveals more than 16,000 fossil footprints from the final days of the dinosaurs

Millions of years before roads connected modern cities, dinosaurs were already following well-worn routes across ancient landscapes. A remarkable fossil site in central Bolivia has preserved this prehistoric movement in extraordinary detail. Scientists have documented more than 16,000 dinosaur footprints at the Carreras Pampa tracksite in Torotoro National Park, making it the world's largest known concentration of dinosaur tracks from a single sedimentary layer. Dating back around 66 million years to the final chapter of the Cretaceous Period, the site offers a rare glimpse into how dinosaurs moved, hunted and interacted shortly before the mass extinction that brought the Age of Dinosaurs to an end.Where is the 66-million-year-old dinosaur highway?The fossil tracksite is located at Carreras Pampa inside Torotoro National Park in central Bolivia.
