SA fossil could change evolution theories
The oldest fossil ever discovered was in China and it proved that animals with backbones - thought to be our forebears - probably lived in that region 530 million years ago.
Now scientists may have to re-set their evolutionary clock back a further 25 million years because of a fossil discovered in South Australia's Flinders Ranges.
The six centimetre long tadpole-shaped fossil is estimated to be 550 million years old. Most fossils of this era are similar to jellyfish or seaweed, but this appears to be a chordate, meaning it has a primitive backbone and therefore might be the earliest link in the evolutionary chain.
