A team of researchers from across the UK have uncovered prehistoric designs on 10 stone fragments, thought to be somewhere between 14,000 and 23,000 years old.
The fragments which are thought to be parts of ornamental tablets, or plaquettes, were found at the Les Varines archaeological site in the south east of Jersey.
The experts believe the abstract engravings were made by the Magdalenians, early hunter gatherers who lived across Europe towards the end of the most recent Ice Age.
The findings are published in the journal Plos One.
Dr Chantal Conneller, a senior lecturer at Newcastle University and one of the authors on the study, said: “These engraved stone fragments provide exciting and rare evidence of artistic expression at what was the farthest edge of the Magdalenian world.
“The people at Les Varines are likely to have been pioneer colonisers of the region and creating engraved objects at new settlements may have been a way of creating symbolic relationships with new places.”
The Magdalenian era is thought to represent the culmination of cultural development in Europe around 18,000 years ago.
From cave art and tools and weapons decorations to engravings on animal bones and teeth, examples of Magdalenian art have been found in various parts of western Europe.
Plaquettes made by Magdalenians have also previously been uncovered at sites in France, Spain and Portugal.
While Magdalenian settlements are known to have existed as far as north-west Britain, it is the first time artistic stone engravings from this era have been discovered in the British Isles.
The researchers analysed the Les Varines plaquettes, which revealed groups of fine lines that, they believe, were purposefully made using tools made of stones.
The ornamental work also features curved markings, possibly made through repeated incisions.
According to the researchers, the two types of marks may have been created using the same tools, possibly by the same engraver and in short succession.
Lead author Dr Silvia Bello, a researcher at the Natural History Museum in London, said: “Microscopic analysis indicates that many of the lines, including the curved, concentric designs, appear to have been made through layered or repeated incisions, suggesting that it is unlikely that they resulted from the stones being used for a functional purpose.
“The majority of the designs are purely abstract, but others could depict basic forms such as animals, landscapes or people.
“This strongly suggests that the plaquettes at Les Varines were engraved for purposeful artistic decoration.”
The plaquette fragments were found in an area thought to have been used as a hearth, while three of the pieces were recovered from an area of granite slabs which may have served as paving.
Dr Ed Blinkhorn, senior geoarchaeologist at University College London and director of excavations at the site, who is also one of the study authors, said: “The plaquettes were tricky to pick apart from the natural geology at the site – every stone needed turning.
“Their discovery amongst hearths, pits, paving, specialist tools, and thousands of flints shows that creating art was an important part of the Magdalenian pioneer toolkit, as much at camp as within caves.”
