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 whale has been described as a fast, sharp-toothed predator about the size of a dolphin with a short snout, large forward-facing eyes and slicing teeth, according to a study.

"It's essentially a little whale with big eyes and a mouth full of sharp, slicing teeth. Imagine the shark-like version of a baleen whale, small and deceptively cute, but definitely not harmless," said Ruairidh Duncan, lead author of the study.

The ancient whale was named after a Victoria resident Ross Dullard found the fossil, a partial skull with ear bones and teeth, found in 2019 as he walked along the beach.
