Articles relating to the Balaenidae, a family of whales of the parvorder Mysticeti (baleen whales) that contains mostly fossil taxa and two living genera: the right whale (genus Eubalaena), and the closely related bowhead whale (genus Balaena
Balaenidae consists of two genera: Eubalaena (right whales) and Balaena (the bowhead whale, B. mysticetus). Balaenidae was thought to have consisted of only one genus until studies done through the early 2000s reported that bowhead whales and right whales are morphologically (different skull shape) and phylogenically different.
Argentavis is an extinct genus of teratornithid known from three sites in the Epecuén and Andalhualá Formations in central and northwestern Argentina dating to the Late Miocene (Huayquerian). The type species, A. magnificens , is sometimes called the giant teratorn .
For the next 180 years, the family Balaenidae was the subject of great taxonometric debate. Authorities have repeatedly recategorized the three populations of right whale plus the bowhead whale, as one, two, three or four species, either in a single genus or in two separate genera.

Through the 19th and 20th centuries, in fact, the family Balaenidae has been the subject of great taxonometric debate. Authorities have repeatedly recategorized the three populations of right whale plus the bowhead whale, as one, two, three or four species, either in a single genus or in two separate genera.
Scientists used to believe there was a very small remnant population of southern right whales inhabiting New Zealand's main islands (North and South Island), estimated to contain 11 reproductive females. [163] In winter, whales migrate north to New Zealand waters and large concentrations occasionally visit the southern coasts of South Island.
