Early People Sheltered in This Lava Tube 10,000 Years In the past—And It’s Nonetheless in Use Immediately
Fossils and stone instruments present {that a} collapse Saudi Arabia has been used as shelter by people for millennia, as much as the current day
Researchers exploring the Umm Jirsan Lava Tube system.
A primary-of-its-kind examine in northwestern Saudi Arabia means that people and their livestock have been utilizing a cave for shelter sporadically for as much as 10,000 years. The discovering presents perception into the area’s historical past and ecology.
Prior to now decade, satellite tv for pc information and fossil finds have recommended that the Arabian Peninsula was not at all times an arid desert. Durations when the area contained lakes and luxurious greenery may need drawn folks and animals there from Africa, in line with the examine’s authors.
“Immediately, it’s a reasonably harsh atmosphere,” says examine co-author Mathew Stewart, a zooarchaeologist at Griffith College in Brisbane, Australia. Throughout the floor of Saudi Arabia, “the fossil document is simply horrendous”, he says. Wind and scorching warmth cut back bones and artefacts to mud, making them troublesome to check.

However in 2018, Stewart and his colleagues described an 88,000-year-old finger bone from the Saudi Arabian desert — one of many oldest human fossils discovered outdoors of Africa. And in 2020, they described footprints on a lake shore relationship again round 120,000 years. These recommended that the area had tales to surrender.
The researchers turned to caves beneath Harrat Khaybar, an unlimited basalt plain pocked with volcanic craters in northwestern Saudi Arabia. The caves had been made by lava because it flowed from close by volcanoes, forming rocky tunnels because it cooled.
An excavation close to the doorway of 1 cave produced greater than 600 animal and human bones and 44 stone-tool fragments. The oldest stone instruments dated again to as many as 10,000 years in the past, and the oldest human bone fragments had been virtually 7,000 years previous. The examine was revealed on 17 April in PLoS ONE.
Species identifiable within the rock artwork of Umm Jirsan. (A) sheep (Panel 8); (B) goat and two stick figures with instruments on their belts (Panel 8); (C) long-horned cattle (Panel 6), photograph enhanced utilizing the ybk setting on DStretch; (D) ibex with ribbed horns and coat markings (Panel 4).

From “First Proof for Human Occupation of a Lava Tube in Arabia: The Archaeology of Umm Jirsan Cave and Its Environment, Northern Saudi Arabia,” by Matthew Stewart et al., in PLOS ONE, Vol.19, No.4, Article No. e0299292. Printed on-line April 17, 2024
The distribution of samples suggests that folks didn’t stay within the cave for lengthy durations, however stayed there sometimes. Close by rock artwork depicts folks with goats and sheep. The drawings are troublesome so far, however they help the fossil proof that folks used the cave as a spot to relaxation and shelter their herds. Even right this moment, farmers search shade and water in underground lava tubes for themselves and their animals, says Stewart.
In response to Melissa Kennedy, an archaeologist on the College of Sydney in Australia, the discovering means that herders have travelled throughout Harrat Khaybar from oasis to oasis on the identical paths for hundreds of years.
Throughout Harrat Khaybar are paths spanning a whole lot of kilometres, some flanked with stone tombs relationship again round 4,500 years. Kennedy says the routes had been most likely used even sooner than the relationship of the tombs would recommend. “Individuals are very lazy,” says Kennedy. “You discover the simplest route and also you follow it.”
Ahmed Nassr, an archaeologist on the College of Ha’il in Saudi Arabia, says the invention is critical. “This discovery opens new home windows into Arabian analysis in prehistory,” he says. He hopes that additional geographical surveys can be carried out in Saudi Arabia, as a result of they may reveal extra such cave websites. “There are a lot of areas which are unexplored.”
