What is believed to be the oldest vertebrate fossil on Earth has been discovered in South Australia's Flinders Ranges.
ABC’s PM reports that palaeontologists from the South Australian Museum were last night en route to the remote site deep in the north of the state to further authenticate the discovery, which could pre-date the previously oldest fossil found in China by 30 million years.
Our very most distant relative looks like a long tadpole, about 65 centimetres long, with muscles, a head, a fin on its back, but most importantly, a backbone, says PM’s Nance Haxton.
Dated to be at least 560 million years old, the fossil could be the elusive Holy Grail that shows the first ancestors of the human race.
South Australian Museum Director, Dr Tim Flannery, says the discovery is of enormous significance.
”Well, it's not so much humans, it's really the origin of all other things, humans, dogs, birds, fish, everything with a backbone and what it's suggesting is that perhaps this lineage goes back a lot further in time than any of us imagined,” he told PM.
