The Ware Formation (Spanish: Formación Ware) is a fossiliferous geological formation of the Cocinetas Basin in the northernmost department of La Guajira. The formation consists of fine lithic to quartzitic sandstones, mudstones, pebbly conglomerates with sedimentary and metamorphic rock fragments, fossiliferous packstones and sandy to conglomeratic beds with high fossil content. The Ware Formation dates to the Neogene and Quaternary periods; Late Miocene to Early Pleistocene epochs, typically Pliocene (3.5 to 2.8 Ma), Uquian, Chapadmalalan and Montehermosan in the SALMA classification, and has a maximum thickness of 25 metres (82 ft).
