Aussie dinosaur bone takes bite out of theory of continental drift
The 19-centimetre (eight-inch) bone was found in southeastern Australia but it comes from a very close cousin to Megaraptor, a flesh-ripping monster that lorded over swathes of South American some 90 million years ago.
The extraordinary similarity between the two giant theropods adds weight to a dissident view about the breakup of a super-continent, known as Gondwana, that formed the continents of the southern hemisphere, the authors say.

I think the move to cancel out the idea of continental drift is too precipitous with little research behind it. And just one fossil to do it? How about the climate and ecology of the two areas 90 million years ago? How does finding two similar fossils disprove continental drift considering they were found on two separate continents? I think the writer didn't do a good enough job at proving there is a dilemma at all.
The super continent was Pangea, when it broke into two it was Gonwonaland and Lurasia before the next separation.
