Source: Wikipédia
The Chacarilla Formation (Spanish: Formación Chacarilla) is an Oxfordian to Early Cretaceous geologic formation of the Tarapacá Basin in northern Chile, close to the border with Bolivia. The marine and fluvial formation preserves several dinosaur trackways and has been declared a Natural Sanctuary (Spanish: Santuario de la Naturaleza) in 2004.
