First evidence of ancient human occupation found in giant lava tube cave in Saudi Arabia

If you look from above, you can see thousands of stone structures dotting the landscape of the Arabian peninsula. On the ground, you can find a bounty of stone tools and ancient fireplaces scattered along the edges of ancient lakes, as well as rock art depicting hunting and herding scenes in the surrounding mountains.

Despite the visibility of these sites, only in the past decade or so have archaeologists taken a dedicated interest in them. Some of the structures have now been dated at up to 10,000 years old.

However, the arid climate, baking days and freezing nights, and intense wind erosion are not kind to some of the other relics archaeologists prize. To date, there has been little found in the way of fossils or the kind of deeply buried, layered deposits that can open a window onto the history of a place.

Until recently, no archaeologists had surveyed any of the hundreds of caves and lava tubes recorded across northern Arabia. In 2019, our team began to look in these subterranean locations – and in a new study published today in PLoS ONE, we report on the first documented occupation of a lava tube in the Arabian Peninsula.

The Umm Jirsan lava tube

The Umm Jirsan lava tube lies some 125 kilometres north of the city of Madinah, in the Harrat Khaybar lava field. The tube formed long ago by cooling lava. It winds an impressive 1.5 kilometres, and reaches 12 metres in height and 45 metres in width in some sections.

The first thing you notice when venturing into the tube’s dark and meandering tunnels is the sheer number of animal remains. The floor is strewn with piles of bones containing thousands – if not hundreds of thousands – of exceptionally preserved fossils.
