Bouetel and C. Muizon. 2006. The anatomy and relationships of Piscobalaena nana (Cetacea, Mysticeti), a Cetotheriidae s.s. from the early Pliocene of Peru〕 == Description == This animal looked much like whales today, particularly small whales. The length was less than 5 meters, and the skull of an adult was about one meter. ''Piscobalaena'' is known for some well-preserved specimens, including three young individuals and an adult. Some characteristics of the skull distinguish ''Piscobalaena'' from modern whales (such as the shape of the supraorbital process).
