Toro Toro Formation (Bolivia)

The Toro Toro Formation is a Late Campanian geologic formation pertaining to the Puca Group of central Bolivia. The porous yellowish medium-to-coarse grained ferruginous (iron-containing) sandstones and mudstones with gypsum intercalations, deposited in a beach environment, preserve many ichnofossils of Ligabueichnium bolivianum, Dromaeopodus sp.,[1] Ornithopoda indet., Theropoda indet. and Titanosauridae indet.[2] The formation has provided the earliest known tracksite of dinosaurs in Bolivia.[3] The Toro Toro Formation represents part of the postrift stage in an alluvial to deltaic environment within the Potosí Basin. The formation is a local equivalent of the Chaunaca Formation.[4] The most famous of the dinosaur tracksites is Cal Orcko, however these are in the El Molino Formation
