Chonecetus is an extinct genus of primitive baleen whale of the family Aetiocetidae[1] that lived in the Oligocene period.[2] Its fossils have been found in Canada,[3] in the northeast Pacific.[4] It was first named by L.S. Russell in 1968, and contains one species, C. sookensis.
Like Aetiocetus, Chonecetus possessed both multicusped teeth and the nutrient foramina required for baleen.[5] 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.[1]
