Tohoraata
''Tohoraata'' is a genus of eomysticetid baleen whale from the Late Oligocene (Chattian) of New Zealand. There are two recognized species, ''T. raekohao'' and ''T. waitakiensis''.〔Robert W. Boessenecker and R. Ewan Fordyce (2014). "A new Eomysticetid (Mammalia: Cetacea) from the Late Oligocene of New Zealand and a re-evaluation of ‘Mauicetus’ waitakiensis".

==Classification==
''Tohoraata'' is a member of the family Eomysticetidae, a family of primitive baleen-bearing mysticetes (chaeomysticetes). The type species, ''T. raekohao'', is based on OU 22178, a partial skull associated with a thoracic vertebra and five ribs, collected from the Maerewhenua Member of the Otekaike Limestone. On the other hand, ''T. waitakiensis'', is known from OMC GL 402, a partial skull and five neck vertebrae collected in the Kokoamu Greensand. It was originally described as a species of ''Mauicetus'',〔B. J. Marples. 1956. Cetotheres (Cetacea) from the Oligocene of New Zealand. Proceedings of the Zoological Society of London 126(4):565-580〕 but was eventually recognized as more primitive than the type species of ''Mauicetus'', being closely related to ''Eomysticetus'' and ''Yamatocetus''.〔Steeman, M. E. 2007. Cladistic analysis and a revised classification of fossil and recent mysticetes. Zoological Journal of the Linnean Society, 150, 875–894.〕
