Dating back one million years, the remarkably intact skull has been hailed as an important find by palaeoanthropologists.
One of our ancient ancestors held on for so long that it was still around when modern humans arrived on the scene.
An engraving found on a fossilized shell is believed to have been made over 430,000 years ago.
Homo erectus may have travelled across the world's oceans as early as 130,000 years ago.
Scientists now believe homo erectus and modern humans never co-existed in the distant past.
New evidence suggests homo erectus may have originated in Asia and not Africa as previously thought.
