Scientists from the US and Russia have pieced together 80% of the species' genome, using DNA samples of
hair preserved from two mammoths mummified from the ice age.
They hope the ground-breaking development will be a step closer in bringing back the vast beasts from extinction, by inserting their genes into a modern-day elephant.
Professor Stephan Schuster, a leading member of the research team from Pennsylvania State University, said the find would allow scientists to retrieve the genetic information that was believed to have been lost when the mammoth died out.
He added it may "bring an extinct species that modern humans have missed meeting by only a few thousand years."
But there may be setbacks, as thousands of years of frozen ice has caused the genetic material to be degraded.
The team also faces the challenge of telling apart intact DNA samples from damaged ones.
It is possible to be fooled into thinking samples contaminated with DNA from fungi and micro-organisms originate from a mammoth.
It's hoped the research can help explain why woolly mammoths became extinct, unlike elephants, their closest living relative.
Dr Jeremy Austin from the Australian Centre for Ancient DNA, at the University Of Adelaide added: "Currently we only have a partial mammoth genome, with a sizeable number of errors in the genetic code.
"It's a bit like trying to build a car with only 80% of the parts and knowing that some parts were already broken."
Those hoping to visit a woolly mammoth theme park any time soon may be in for quite a wait...
