Gigantopithecus -- the closest Nature ever came to producing a real King Kong -- weighed five times as much as an adult man and probably stood three metres (nine feet) tall, according to sketchy estimates.
In its heyday a million years ago, it inhabited semi-tropical forests in southern China and mainland Southeast Asia.
