Ancient New Zealand ‘dawn whale’ identified

18 noviembre 2014

Palaeontologists are rewriting the history of New Zealand’s ancient whales by describing a previously unknown genus of fossil baleen whales and two species within it. The two whales, which lived between 27-25 million years ago, were preserved in a rock formation near Duntroon in North Otago. At that time the continent of Zealandia was largely or completely under water and the whales were deposited on a continental shelf that was perhaps between 50 to 100 meters deep.
