Waipatia

Waipatia is an extinct genus of whale from the late Oligocene (Chattian) of New Zealand.
Taxonomy.
The type species, "Waipatia maerewhenua" is known from a single skull found near 45° South in Otago . The second species, "W. hectori", was originally named "Microcetus hectori" in 1935, but later recognized as distinct from "Microcetus". "Uncamentodon" was informally coined for "M. hectori" in a table by Rothausen in a 1970 paper, but the lack of a diagnosis or description made it a nomen nudum. Finally in 2015, "M. hectori" was recognized as a second species of "Waipatia" based on preparation of additional material included in the holotype.
