The Catavi Formation is a Pridoli to Emsian geologic formation of northern and central Bolivia. The formation comprises a {{convert|456|m|ft|abbr=on}} thick succession of fine-grained, olive to brown sandstones and siltstones, shales and black limestones deposited in a shallow to deep marine environment.[https://paleobiodb.org/classic/displayCollResults?collection_no=25587 Catavi Unit C3 near Cochabamba] at Fossilworks.org[https://paleobiodb.org/classic/displayCollResults?collection_no=25592 Catavi vertebrate and mollusc fauna at Seripona] at Fossilworks.org[https://paleobiodb.org/classic/displayCollResults?collection_no=37052 Catavi Beds, (Phacopina chojnacotensis bed) La Paz Province, Bolivia] at Fossilworks.org[https://paleobiodb.org/classic/displayCollResults?collection_no=25584 Catavi Unit C1 near Cochabamba] at Fossilworks.org[https://paleobiodb.org/classic/displayCollResults?collection_no=25579 Trilobite faunule in Catavi unit C2 near Cochabamba] at Fossilworks.org
