In a study published Tuesday<\/a>, scientists say they discovered a “fast, sharp-toothed predator” that would have been about the size of a dolphin.<\/p>\n “It’s essentially a little whale with big eyes and a mouth full of sharp, slicing teeth,” said researcher Ruairidh Duncan. “Imagine the shark-like version of a baleen whale \u2014 small and deceptively cute, but definitely not harmless.”<\/p>\n Museums Victoria released a video<\/a> showing Duncan discuss the discovery and how researchers were able to identify the species.<\/p>\n Janjucetus dullardi\u00a0calf and mother swimming through the shallow seas off Victoria, 25 million years ago.\u00a0<\/p>\n Art by Ruairidh Duncan\/Museums Victoria<\/p>\n The skull belonged to a group of prehistoric whales known as the mammalodontids, distant smaller relatives of today’s filter-feeding whales.<\/p>\n It is the fourth mammalodontid species ever discovered, Museums Victoria said. And it is the third to be identified in Victoria following\u00a0discoveries in 2006 and 1939<\/a>, the Australian Broadcasting Corporation reported.<\/p>\n “This fossil opens a window into how ancient whales grew and changed, and how evolution shaped their bodies as they adapted to life in the sea,” said palaeontologist Erich Fitzgerald, who co-authored the study.<\/p>\n Victoria’s Surf Coast lies on the Jan Juc Formation \u2014 a geological feature dating to the Oligocene epoch between 23 and 30 million years ago.<\/p>\n A string of rare fossils have been unearthed along the scenic stretch of beach, a renowned site for the study of early whale evolution.<\/p>\n “This region was once a cradle for some of the most unusual whales in history, and we’re only just beginning to uncover their stories,” said Fitzgerald. “We’re entering a new phase of discovery.<\/p>\n “This region is rewriting the story of how whales came to rule the oceans, with some surprising plot twists.”<\/p>\n Fitzgerald told the ABC<\/a> the whale was unique to Australia.<\/p>\n “If they were alive today, they would be as iconically Australian as a kangaroo,” he said.<\/p>\n The species was named Janjucetus dullardi, a nod to local Ross Dullard who stumbled across the skull while strolling the beach in 2019.<\/p>\n It was described in the peer-reviewed Zoological Journal of the Linnean Society<\/a>.<\/p>\n![\"whale-screenshot-2025-08-13-072143.png](\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2025\/08\/whale-screenshot-2025-08-13-072143.png#.png\")
