The Anzaldo Formation is a Katian geologic formation of central Bolivia. The formation belongs to the Cochabamba Group, overlies the Capinota Formation and is overlain by the San Benito Formation. The formation is famous for being where the Sacabambaspis, a jawless fish that has become a popular internet meme in recent years was discovered.[https://paleobiodb.org/classic/displayStrata?geological_group=&formation=Anzaldo&group_formation_member=Anzaldo Anzaldo Formation] at Fossilworks.org
