Ancient New Zealand 'Dawn Whale' (IMAGE) University of Otago Caption University of Otago researchers have described a new genus of ancient baleen whales that they have named Tohoraata (a Māori term which can be translated as Dawn Whale). The genus belongs to the toothless filter-feeding family Eomysticetidae, and it is the first time members of this family have been identified in the Southern Hemisphere. They named the younger of the two fossil whales, which may be a descendent of the elder, as Tohoraata raekohao (pictured). Raekohao means 'holes in the forehead.' Researcher Robert Boessenecker says this whale lived between 26-25 million years ago and vaguely resembles a minke whale but was more slender and serpent-like. Its skull, which contains a number of holes near its eye sockets for arteries, was probably about 2 meters in length and the whole animal would have been 8 meters long.
