Unlike the gentle giants that cruise today's oceans, Janjucetus dullardi was a compact, sharp-toothed predator, more reminiscent of a dolphin than a whale.

Aug. 13 (UPI) -- Prehistoric fossils have led to the discovery of an ancient whale species off the coast of Australia. Scientists said the species, Janjucetus dullardi, is one of the earliest cousins of modern whales but was not an ocean giant, researchers from Museums Victoria Research Institute said.

The ancient 'baby whale' was the size of a dolphin with eyes the size of tennis balls and lived around 30million years ago.
