Scientists discover astonishing razortooth whale which lived 25 million years ago

The 26-million-year-old Janjucetus dullardi was a dolphin-sized predator with sharp teeth and large eyes, providing new insights into early whale evolution and climate adaptation.

  • On August 12, Museums Victoria Research Institute scientists described Janjucetus dullardi, a juvenile whale just over two metres long, from a 26-million-year-old fossil near Jan Juc on Wadawurrung Country, Victoria's Surf Coast.
  • Amid the Oligocene epoch, Victoria's Surf Coast sits atop the Jan Juc Formation, which dates to between 23 and 30 million years ago, and this is the third mammalodontid species from Victoria and only the fourth worldwide.
  • Ruairidh Duncan said the species resembled a small whale, 'with big eyes and a mouth full of sharp, slicing teeth,' highlighting its predator features.
  • Researchers say studying the fossil will improve understanding of early whale behaviours and may help predict how modern marine ecosystems adapt to climate change in coming years.
