Mauicetus is a genus of extinct baleen whale from the Late Oligocene of New Zealand.

Taxonomy

Mauicetus was originally named Lophocephalus by William Benham, but that name was already used for a beetle, and Benham provided the replacement name Mauicetus. [1] [2] Three more species were named in 1956: M. brevicollis, M. lophocephalus, and M. waitakiensis. [3] Nowadays, Mauicetus parki is considered a stem-balaenopteroid, while M. lophocephalus and M. waitakiensis have been reclassified in Eomysticetidae, with M. lophocephalus and M. waitakiensis being assigned to Tokarahia and Tohoraata .

Neobalaenidae is a family of baleen whales including the extant pygmy right whale. Although traditionally considered related to balaenids, a recent phylogenetic study by Fordyce and Marx (2013) recovered the living pygmy right whale as a member of Cetotheriidae, making it the only extant cetotheriid, but not all authors agree with this argument.

Cetotheriidae is a family of baleen whales. The family is known to have existed from the Late Oligocene to the Early Pleistocene before going extinct. Although some phylogenetic studies conducted by Fordyce & Marx 2013 recovered the living pygmy right whale as a member of Cetotheriidae, making the pygmy right whale the only living cetotheriid, other authors either dispute this placement or recover Neobalaenidae as a sister group to Cetotheriidae.

The Kokoamu Greensand is a geological formation found in New Zealand. It is a fossil-bearing, late Oligocene, greensand rock unit of the eastern South Island, especially the Waitaki District of North Otago and the southern Canterbury region. The formation was named by geologist Maxwell Gage in the 1950s. In North Otago it underlies the thicker and harder Otekaike Limestone. The formation gets its green colour from the mineral glauconite which forms slowly on the ocean floor.
