We present an update and a review of the Late Cretaceous dinosaur tracksites Bolivia. The Puca Group (Coniacian – Maastrichtian) records tracks trackways two different titanosaurid sauropods, ankylosaurs, hadrosaurs theropod groups from Central Andean lacustrine back arc basin. sites Maragua syncline (Chuquisaca) new data on famous Toro site (Potosi). Furthermore, first complete map world's largest tracksite, Cal Orck'o (El Molino Formation, Sucre) gives insight into behavior movement patterns. Parallel subadult ankylosaurs provide unequivocal evidence social amongst these dinosaurs worldwide. El Formation coeval deposits Southern Peru Northern Argentina form megatracksite with size around 100,000 km2. paleogeographic position main within basin suggests that they are part seasonal migration route along shoreline deltas ancient lake system.
