Early Humans Sheltered in This Lava Tube 10,000 Several years Ago—And It’s Nevertheless in Use Today
Fossils and stone tools demonstrate that a cave in Saudi Arabia has been employed as shelter by humans for millennia, up to the existing working day
Scientists exploring the Umm Jirsan Lava Tube method.
A initially-of-its-type research in northwestern Saudi Arabia implies that human beings and their livestock have been utilizing a cave for shelter sporadically for up to 10,000 yrs. The locating gives insight into the region’s history and ecology.
In the earlier ten years, satellite knowledge and fossil finds have advised that the Arabian Peninsula was not usually an arid desert. Durations when the location contained lakes and lush greenery may well have drawn persons and animals there from Africa, according to the study’s authors.
“Today, it is a relatively harsh surroundings,” suggests study co-writer Mathew Stewart, a zooarchaeologist at Griffith University in Brisbane, Australia. Throughout the area of Saudi Arabia, “the fossil file is just horrendous”, he states. Wind and scorching heat decrease bones and artefacts to dust, generating them hard to research.

But in 2018, Stewart and his colleagues explained an 88,000-12 months-aged finger bone from the Saudi Arabian desert — one particular of the oldest human fossils found outside of Africa. And in 2020, they explained footprints on a lake shore courting back about 120,000 many years. These suggested that the region experienced tales to give up.
The researchers turned to caves under Harrat Khaybar, a huge basalt simple pocked with volcanic craters in northwestern Saudi Arabia. The caves ended up created by lava as it flowed from nearby volcanoes, forming rocky tunnels as it cooled.
An excavation in the vicinity of the entrance of one cave created far more than 600 animal and human bones and 44 stone-device fragments. The oldest stone applications dated back again to as lots of as 10,000 several years back, and the oldest human bone fragments were just about 7,000 many years aged. The review was revealed on 17 April in PLoS 1.

From “First Evidence for Human Occupation of a Lava Tube in Arabia: The Archaeology of Umm Jirsan Cave and Its Surroundings, Northern Saudi Arabia,” by Matthew Stewart et al., in PLOS A single, Vol.19, No.4, Posting No. e0299292. Published on line April 17, 2024
The distribution of samples indicates that men and women did not live in the cave for extensive durations, but stayed there once in a while. Nearby rock artwork depicts persons with goats and sheep. The drawings are hard to date, but they aid the fossil evidence that persons utilised the cave as a put to relaxation and shelter their herds. Even currently, farmers seek out shade and water in underground lava tubes for themselves and their animals, states Stewart.
In accordance to Melissa Kennedy, an archaeologist at the College of Sydney in Australia, the obtaining implies that herders have travelled throughout Harrat Khaybar from oasis to oasis on the exact same paths for countless numbers of many years.
Throughout Harrat Khaybar are paths spanning hundreds of kilometres, some flanked with stone tombs relationship back again close to 4,500 a long time. Kennedy says the routes were being probably made use of even earlier than the relationship of the tombs would recommend. “People are incredibly lazy,” states Kennedy. “You locate the simplest route and you stick to it.”
Ahmed Nassr, an archaeologist at the College of Ha’il in Saudi Arabia, suggests the discovery is sizeable. “This discovery opens new windows into Arabian analysis in prehistory,” he states. He hopes that even more geographical surveys will be performed in Saudi Arabia, mainly because they could reveal much more these cave web pages. “There are quite a few locations that are unexplored.”
