New research led by the University of Southampton shows Neanderthals kept coming back to a coastal cave site in Jersey from at least 180,000 years ago until around 40,000 years ago.

As part of a re-examination of La Cotte de St Brelade and its surrounding landscape, archaeologists from Southampton, together with experts from two other universities and the British Museum, have taken a fresh look at artefacts and mammoth bones originally excavated from within the site’s granite cliffs in the 1970s. Their findings are published in the journal Antiquity.



The researchers matched types of stone raw material used to make tools to detailed mapping of the geology of the sea bed, and studied in detail how they were made, carried and modified. This helped reconstruct a picture of what resources were available to Neanderthals over tens of thousands of years – and where they were travelling from.



Lead author Dr Andy Shaw of the Centre for the Archaeology of Human Origins (CAHO) at the University of Southampton said: “La Cotte seems to have been a special place for Neanderthals. They kept making deliberate journeys to reach the site over many, many generations. We can use the stone tools they left behind to map how they were moving through landscapes, which are now beneath the English Channel. 180,000 years ago, as ice caps expanded and temperatures plummeted, they would have been exploiting a huge offshore area, inaccessible to us today.”



Previous research focussed on particular levels in the site where mammoth bones are concentrated, but this new study took a longer-term perspective, looking at how Neanderthals used it and explored the surrounding landscape for over 100,000 years.



The team, including academics from the British Museum, University College London (UCL) and the University of Wales found that Neanderthals kept coming back to this particular place, despite globally significant changes in climate and landscape. During glacial phases (Ice Ages), they travelled to the site over cold, open landscapes, now submerged under the sea. They kept visiting as the climate warmed up and Jersey became a striking highpoint in a wide coastal plain connected to France.
