Balenoptera is a Cetacean belonging to the family of Balaenopteridae, a group of baleen whales, which also include the current humpback whale, blue whale, whale of Bryde, common whale and minke whale.
It is believed that the family of Balenopteridae has been separated from the other families of the suborder Mysticeta, also called baleen whales or great whales, in the middle Miocene. However, little is known of when the members of the various families of Mysticeta, including Balenopterida, separated from each other. The list of extinct cetaceans, from lower Eocene is very large and equally incomplete. The Cetacea order (whales, dolphins and porpoises) are descendants of extinct mammals ungulates artiodactyls, slowly adapted to aquatic life. At first they are specialized for swimming than for walking on land, and then eventually they evolved into fully marine cetaceans.
