The Catavi Formation is a Pridoli to Emsian geologic formation of northern and central Bolivia. The formation comprises a thick succession of fine-grained, olive to brown sandstones and siltstones, shales and black limestones deposited in a shallow to deep marine environment.Catavi Unit C3 near Cochabamba at Fossilworks.orgCatavi vertebrate and mollusc fauna at Seripona at Fossilworks.orgCatavi Beds, (Phacopina chojnacotensis bed) La Paz Province, Bolivia at Fossilworks.orgCatavi Unit C1 near Cochabamba at Fossilworks.orgTrilobite faunule in Catavi unit C2 near Cochabamba at Fossilworks.org
