The holotype of †Whakakai waipata is a partial skull, periotics, tympanic bulla, vertebrae and scapula. The earbone morphology of †Whakakai waipata shows a unique combination of diagnostic features including: massive periotic; flange of posterior process and caudal tympanic process flooring stapedial muscle fossa; and an elongated stylomastoid fossa that invades the robust posterior process of the periotic. The tympanoperiotic features in †Whakakai waipata suggest a different acoustic niche from other Oligocene mysticetes, and by inference different feeding habits and habitat. |
