Cal Orck'o is a rock wall bearing thousands of dinosaur footprints, in a quarry about 4.4 km north-west of Sucre. The Parque Cretácico overlooks it, the most visited museum in the city. The site is on UNESCO's tentative list, and legislators are working on a law to declare it heritage. The rocks date from the late Cretaceous and were the bed of an old lake in the El Molino Formation. Workers found the site by chance in 1994 during quarrying, and movements of the earth have tilted the layer to almost vertical, at about 70 degrees. Mapping from 1998 to 2015 revealed 12,092 tracks in 465 trackways, from nine different types of dinosaur. From the platform you see a huge grey wall of about 65,000 square metres, with long lines of round hollows as if dinosaurs had walked up a wall. The park has life-size models that delight children, and panels on the geology. A guided tour helps you make sense of the types, and the light is best before noon. A quarry and cement plant stand beside it. The site is 4.7 km in a straight line north-west of central Sucre, an easy taxi ride. The wall is suffering erosion, so go closer only with park permission and a guide. The sun is strong and shade scarce, so bring a hat and water. British advice mentions a state of emergency and road blockades, so check your government's advice before visiting.

They were on a flat lake bed, later tilted by earth movements to almost vertical.
Yes, they enjoy the giant models, but watch them near the edges.
