For nearly two million years a species of giant ape called Gigantopithecus Blacki (Giganto) roamed the Earth.
They were thought to have stood at 3 metres tall and weighed up to 300 kilograms.
Then, suddenly, Giganto disappeared from the fossil record, leaving nothing behind but a couple of bits of jawbone and thousands of teeth, hidden in caves mostly in southern China.
Dr Kira Westaway has been on a ten-year mission to solve the mystery of how, why and when this real-life King Kong became extinct, and why nothing remains of the beasts but teeth.
Her team has just solved one of those mysteries.
