Russell in 1968, and contains one species, C. sookensis.
Like Aetiocetus, Chonecetus possessed both multicusped teeth and the nutrient foramina required for baleen.Marine Mammals: Evolutionary Biology; page 62. By Annalisa Berta, James L. Sumich, and Kit M. Kovacs, published 2005; Academic Press. Retrieved on July 1, 2008. Chonecetus closely resembled a modern Mysticeti, with an elongate, streamlined body supporting a pair of paddle-shaped forelimbs, and a horizontal tail fluke strengthened by fibrous cartilage.
