Tiny new North Pacific fossil whale from 30 million years ago

A new species of fossil baleen whale that lived in the North Pacific Ocean 30 to 33 million years ago has been described. The whale, named Fucaia buelli by the researchers, is transitional between ancient toothed whales and the baleen whales of modern seas. It is one of the oldest baleen whales ever found and, at a length of about 2-2.5m, also one of the smallest.
