The origins of writing have long been anchored to Mesopotamia, where proto-cuneiform clay tablets dating to around 3500 to 3350 BC represent the earliest known proto-writing system. A new study challenges that timeline by more than 30,000 years.
Researchers examined sequences of symbols engraved on 260 artefacts recovered from caves in the Swabian Jura region of south-west Germany. The objects — flutes, animal figurines, animal-human hybrid carvings, and pendants — were produced between 43,000 and 34,000 years ago by some of the earliest Homo sapiens groups to reach Europe during a period known as the Aurignacian. Across these items, more than 3,000 engravings were made using 22 distinct symbols, the most common being V-shaped notches, followed by lines, crosses, and dots, with Y- and star-shaped signs appearing less frequently.
The study, conducted by archaeologist Ewa Dutkiewicz of the Museum of Prehistory and Early History in Berlin and linguist Christian Bentz of Saarland University, applied computer models to measure the complexity and information density of these symbol sequences. The researchers then compared the statistical properties of the Aurignacian sequences against both proto-cuneiform and modern writing systems. According to the announcement, the Stone Age sequences were clearly distinguishable from modern writing — but closely matched the earliest proto-cuneiform tablets. “The features are very, very similar,” says Bentz.
Sequences, Not Just Symbols
The analytical focus on sequences rather than individual signs is central to the study’s argument. As Bentz explains, “information is not only encoded in the number of different signs you have, but… in how you combine the signs.” The English alphabet illustrates this: 26 letters, combined in structured patterns, encode the full range of spoken language sounds. The same logic applies to the Aurignacian material — the systematic, repeating arrangement of marks suggests a form of intentional organisation, not random decoration.
Dutkiewicz draws a clear distinction between generic ancient mark-making and what appears on these artefacts. “Having this reoccurring, very systematic use of clearly applied marks distinct from each other, put into sequences — that’s completely something different,” she says. The researchers argue this fulfils one definition of writing: a system enabling human communication through a convention of visible marks.
What the Evidence Does and Does Not Show
Palaeoanthropologist Genevieve von Petzinger, commenting on the findings, describes the result as demonstrating “pattern repetition and organisation” in the Aurignacian pieces, with a configurational structure that “closely matches proto-cuneiform.” She stops short of equating the two systems in meaning.
That distinction matters. Proto-cuneiform is understood to have originated as an accounting system — tracking quantities of crops and goods. What the 40,000-year-old symbols recorded, if anything specific, remains unknown. Without an equivalent of the Rosetta Stone, direct interpretation is not possible. The study’s claim is structural, not semantic: that hunter-gatherers in Ice Age Europe were combining symbols in ways statistically consistent with the earliest documented proto-writing, suggesting the cognitive architecture for recorded communication predates previous estimates by a significant margin.
