 TONY EASTLEY: Scientists have found an ancient species they're calling platypus Godzilla. 
  
  
  
 It existed five to 15 million years ago and was twice the size of the species swimming in Australian rivers at the moment. 
  
  
  
 And unlike its modern descendent the ancient version had teeth to possibly chew crayfish, frogs and small turtles. 
  
  
  
 Palaeontologists say the fossil is forcing a re-think about the evolution of the species. 
  
  
  
 Tom Nightingale reports. 
  
  
  
 TOM NIGHTINGALE: In the arid lands of northern Australia, Professor Mike Archer has been studying an ancient rainforest waterhole, and he's found something he didn't expect. 
  
  
  
 MIKE ARCHER: Well it pretty well blew our minds. We thought we were beginning to get a hold on an understanding about the evolutionary history of platypuses. Even though we haven't got a lot of material it was making a consistently simple story. 
  
  
  
 TOM NIGHTINGALE: Until now, palaeontologists thought the platypus became smaller and lost teeth as time went on. 
  
  
  
 MIKE ARCHER: And it seemed like a simple story, a worrying, but a simple story. And then bang, out of the blue drops this monster - platypus Godzilla. We didn't expect this. It's a huge platypus at the wrong time. I mean I expected it to be a long time ago but here it was. 
  
  
  
 TOM NIGHTINGALE: Professor Archer is most surprised by the size and the jaw of the species he's just found. 
  
  
  
 He believes it was about a metre long - twice the size of the modern species. 
  
  
  
 And the ancient platypus had teeth as an adult unlike the modern species which only has teeth when young. 
  
  
  
 The University of New South Wales palaeontologists only found a tooth, but Professor Archer says that's enough. 
  
  
  
 MIKE ARCHER: We know it's a platypus. We also know it's very different than any other tooth platypus we've seen before. 
  
  
  
 TOM NIGHTINGALE: Are you certain that it's a metre long though? I mean, are you able to tell that with just a tooth? 
  
  
  
 MIKE ARCHER: It's been demonstrated for a long time that there's a tight correlation between the size of the molar teeth in a mammal and the body size, total body size, of the animal. So at the very least you can say this tooth is twice as big as the appropriate position would be in a modern platypus but we might even be being conservative saying that it was about a metre long. It could well have been a bit longer. 
  
  
  
 You would have put a sign up by the pool here - no swimming with this kind of platypus. It's probably dangerous. 
  
  
  
 TOM NIGHTINGALE: Every year the team visit the site near Camooweal. 
  
  
  
 They take a few tonnes of limestone back to a lab in Sydney, where they dissolve it in acid to reveal the fossils. 
  
  
  
 Riversleigh is a World Heritage area and it's regarded as one of the world's top fossil sites. 
  
  
  
 Professor Archer says the latest find is also a warning. 
  
  
  
 MIKE ARCHER: So the long term message here of platypuses in general is that it's a message of a group that has been creeping out on the edge of its evolutionary branch. 
  
  
  
 And experience teaches us in studying other groups in the fossil record, like the thylacines, that when that happens, that branch is increasingly likely to break off. So as palaeontologists we're very concerned about the long term viability of the platypus. 
  
  
  
 Now to find this new platypus only adds to our worry, 'cause it only says that there were more kinds of platypus than we even realise that have now gone. 
  
  
  
 TOM NIGHTINGALE: The study is being published today in the Journal of Vertebrate Palaeontology.

Output:
As if platypuses weren't weird enough already, scientists in Australia have come upon a fossilized tooth of what they're calling "platypus-zilla"—a creature some three feet long, or at least twice the size of your everyday platypus. "It probably would have looked like a platypus on steroids," says researcher Mike Archer, citing a "gigantic monstrosity that you would have been afraid to swim with." But the find, which lived between 5 million and 15 million years ago, won't just haunt researchers' dreams; it reveals a lot about the evolutionary history of the platypus, the BBC reports. Scientists had thought "maybe it was just one lineage of strange animals bumbling its way through time and space at least for the last 60 million years," Archer says. Instead, platypus-zilla "indicates there are branches in the platypus family tree that we hadn't suspected before." The tooth's bumps and other local fossils suggest it ate crustaceans, fish, turtles, and frogs, the BBC notes; modern platypuses have teeth only while young, Australia's ABC News notes.
