Round 12,000 years in the past, a person was shot by an arrow with an unique stone tip in what’s now Vietnam. He survived the preliminary damage however doubtless succumbed to an infection, a brand new evaluation of his stays suggests.
The person’s well-preserved skeleton will be the earliest proof of violence in Southeast Asia, the research authors declare, though some researchers say extra proof is required to make that conclusion.
In a research printed Wednesday (Aug. 27) within the journal Proceedings of the Royal Society B: Organic Sciences, the researchers detailed their evaluation of the person’s skeleton, dubbed TBH1. The person was about 35 years previous when he died not less than 12,000 years in the past, in the course of the late Pleistocene epoch (126,000 to 11,700 years in the past).
The skeleton was initially excavated in 2018 from Thung Binh 1, a cave within the Tràng An Panorama Advanced in north Vietnam. He had been buried within the fetal place, along with his face resting on his palms.
Though the cranium of TBH1 had been crushed, researchers had been in a position to reconstruct his skull and jaws. A primary look advised that, aside from having a minor ankle damage, the person was in good well being when he died.
However a extra thorough evaluation of the person’s skeleton revealed an anatomical anomaly: an extra rib. Whereas most individuals have 24 ribs, between 0.2% and 1% of individuals have an additional one, referred to as a supernumerary rib, the researchers wrote within the research. This man’s further rib was close to his neck. Notably, TBH1’s “bonus” rib was fractured, and it confirmed indicators of an infection; particularly, a spot within the bone the place pus would have drained.
“TBH1 lived for a number of months after the damage occurred,” the researchers wrote within the research. “With out efficient remedy” of the fracture, although, “that is prone to have led to bacterial and different types of an infection,” they wrote, resulting in loss of life from an infection inside weeks or months after his damage.

Close to the contaminated further rib, the researchers found a small, triangular quartz flake they described as a “micropoint.” The purpose, which measured round 0.72 inches (18 millimeters) lengthy, had proof of notching. This implies the purpose was used as a barb on a projectile, comparable to a dart or an arrow, research co-author Christopher Stimpson, a zooarchaeologist on the Pure Historical past Museum in London, instructed Dwell Science in an electronic mail.
“The purpose is very intriguing,” research co-author Benjamin Utting, an archaeologist on the Smithsonian Nationwide Museum of Pure Historical past, mentioned within the assertion. “It does not match another stone instruments from Thung Bunh 1 or close by websites, elevating questions on who made it and the place it got here from.”
The mixture of the micropoint close to TBH1’s neck, the person’s contaminated rib, and the unique nature of the quartz suggests the person might have been a sufferer of interpersonal violence, the researchers wrote. This could lengthen the proof of violence between hunter-gatherer teams in east Asia again a number of millennia.
“That is an thrilling new report from a time and place through which we now have only a few well-preserved skeletons to check,” Michael Rivera, a bioarchaeologist on the College of Hong Kong who was not concerned within the research, instructed Dwell Science in an electronic mail. “This quartz projectile may have been the perpetrator resulting in an contaminated rib, however whether or not or not this was an act of violence or an unintended damage is tough to evaluate, in my view.”
TBH1 was doubtless cared for by his group, Rivera mentioned, because the man survived his preliminary damage and was buried rigorously within the cave.
Though TBH1 is a novel burial, Stimpson mentioned, “the hill and its caves do appear to have had a longstanding position as a spot of burial, as evidenced by the later archaeology” on the web site.
