Is it a bird? Is it a plane? Or might it be something else?
THE life-sized reconstruction of the Archaeopteryx fossil in Melbourne Museum’s walk-through gallery has visitors in thrall. Most museums and school textbooks describe the small, crow-sized creature as the world’s ‘‘earliest known bird’’.
But not for much longer. New and compelling evidence from China suggests that museum exhibits and the textbooks may need to be rewritten. That’s because Archaeopteryx, which has the wings of a bird but the teeth and tail of a dinosaur, may not have been a bird after all: it was, palaeontologists now believe, a type of feathered dinosaur that roamed the Earth, and sometimes flew, 150 million years ago.
The controversial revelation, which has rocked the global science community, means that another creature must now be found to explain how birds evolved.
‘‘It seems that the flight of Archaeopteryx as a bird has come crashing to an end,’’ says Melbourne Museum vertebrate palaeontologist Tim Holland. ‘‘The recent fossil find from China has led us to rethink its role in avian evolution.’’
