Matapanui

Matapanui is a genus of eomysticetid baleen whale from the Late Oligocene (early Chattian) Kokoamu Greensand of New Zealand.
Taxonomy.
"Matapanui" was originally named "Matapa", but that name was already in use for a genus of butterfly, necessitating the name change.
Paleobiology.
Based on the enlarged temporal fossae and enlarged mandibular canal, "Matapanui" was probably incapable of lunge-feeding, although it remains unclear whether it could skim-feed or filter prey in the benthic zone. "Waharoa" shared its habitat with the odontocetes "Awamokoa", "Austrosqualodon", "Otekaikea", and "Waipatia", and the mysticetes "Horopeta", "Mauicetus", "Tohoraata", "Tokarahia", "Waharoa", and "Whakakai".
