540000-year-old shell carvings may be human ancestor’s oldest art, The human ancestor Homo erectus used freshwater mussel shells tools as far back as half a million years ago and even carved decorative engravings, new findings revealed.

An international team of researchers, led by Leiden archaeologist José Joordens, published this discovery on 3 December in Nature. The discovery provides new insights into the evolution of human behaviour.

Not only Homo sapiens made engravings
‘Until this discovery, it was assumed that comparable engravings were only made by modern humans – Homo sapiens – in Africa, starting about 100,000 years ago,’ says lead author José Joordens, researcher at the Faculty of Archaeology at Leiden University.

The shell collection of Eugène Dubois
A team of 21 researchers studied hundreds of fossil shells from the Homo erectus site Trinil, on the Indonesian island of Java. The shells are part of the Dubois Collection held at the Naturalis Biodiversity Center in Leiden. The shells were excavated at the end of the 19th century by the Dutch physician and researcher Eugène Dubois, the discoverer of Pithecanthropus erectus – now known as Homo erectus.

Engravings older than weathering
The discovery of an engraved geometrical pattern on one of the shells came as a total surprise. The zigzag pattern, that can only be seen with oblique lighting, clearly pre-dates the weathering processes on the shell arising from fossilisation. The study has excluded the possibility that the pattern could have been caused by animals or by natural weathering processes and shows that the zigzag pattern is the work of Homo erectus.

Pre-dates African finds
By applying two dating methods, researchers at the VU University Amsterdam and Wageningen University have determined that the shell with the engraving is minimally 430,000 and maximally 540,000 years old.This means that the engraving is at least four times older than the previously oldest known engravings, found in Africa.

Purpose or meaning of the engraving?
‘It’s fantastic that this engraved shell has been discovered in a museum collection where it has been held for more than a hundred years. I can imagine people may be wondering whether this can be seen as a form of early art,’ says Wil Roebroeks, Professor of Palaeolithic Archaeology at Leiden University. He was able to finance this long-term research with his NWO Spinoza Prize. ‘At the moment we have no clue about the meaning or purpose of this engraving.’

Early human-like mussel gatherers
This research has shown that these early human-like people were very clever about how they opened these large freshwater mussels; they drilled a hole through the shell using a sharp object, possibly a shark’s tooth, exactly at the point where the muscle is attached that keeps the shell closed. ‘The precision with which these early humans worked indicates great dexterity and detailed knowledge of mollusc anatomy,’ says Frank Wesselingh, a researcher and expert on fossil shells at Naturalis. The molluscs were eaten and the empty shells were used to manufacture tools, such as knives.
