Part of a giant platypus fossil has been unearthed in Queensland, Australia.
Scientists have dubbed the beast "platypus-zilla" and believe it would have measured more than 1m long (3ft).
Writing in the Journal of Vertebrate Paleontology, the researchers say the creature lived between five and 15 million years ago.
The discovery suggests the evolutionary back-story of today's platypus is more complicated than was thought.
Prof Mike Archer, from the University of New South Wales, said: "Suddenly up pops 'playtpus-zilla' - this gigantic monstrosity that you would have been afraid to swim with.
"It indicates there are branches in the platypus family tree that we hadn't suspected before."
There's got to be an alternate-history story about "Platypus" Dundee here somewhere...
