Archaeologists Just Discovered the Oldest Known Evidence of Poison Arrows, Which Hunters Used to Slow Down Their Prey 60,000 Years Ago

Archaeonews Summary

Five of ten quartz-backed microliths from Umhlatuzana Rock Shelter, near Hillcrest in KwaZulu-Natal, South Africa, yielded residues containing the toxic plant alkaloid buphanidrine; one also contained epibuphanisine. The pieces came from a Howiesons Poort context excavated during Jonathan Kaplan’s 1985 rescue work, undertaken after the shelter was threatened by construction of the N3 highway.

Sven Isaksson, Anders Högberg and Marlize Lombard re-analysed the old finds using gas chromatography–mass spectrometry, comparing the residues with historic poisoned arrows and modern Boophone disticha bulb exudate. The relevant deposits are assigned an age of 60 ± 3.5 thousand years by optically stimulated luminescence dating of associated sediments. Use-wear, impact damage and earlier experiments support interpretation of the microliths as arrow tips, although the objects themselves are not preserved complete arrows.

Why It Matters

The result matters because it converts a long-standing hypothesis into direct chemical evidence. Southern African archaeologists had already argued, from microlith form, hafting residues, fractures and experimental work, that bow-and-arrow technology existed more than 60,000 years ago. Until now, however, Pleistocene poison use rested on much less direct evidence, while chemically demonstrated poisoned arrows were thousands rather than tens of thousands of years old. The new analysis therefore strengthens the case that Middle Stone Age hunters combined projectile technology, plant knowledge and delayed-action hunting strategies.

The claim is unusually well supported for an “oldest” story: it appears in the peer-reviewed journal Science Advances, the poison biomarkers were found on five separate artefacts, and the team used archaeological, historic and modern comparison samples. The main caveat is narrower than the headlines suggest. Boophone disticha is the most likely source, not the only plant capable of producing every detected alkaloid, and the exact way these 60,000-year-old weapons were used cannot be reconstructed. The study establishes poison on probable arrow tips; it does not demonstrate that Pleistocene hunters followed prey exactly as historically documented poisoned-arrow hunters did.

* Confidence: high. The underlying claim comes from a peer-reviewed research article, with an explicit archaeological context, OSL age of 60 ± 3.5 ka, GC-MS identification of alkaloids on five of ten tested microliths, and historic and modern comparative samples. ([PubMed Central (PMC)][2])
* Not verified: nothing material; the site’s location near Hillcrest and the 1985 rescue-excavation history were cross-checked against independent archaeological publications. ([Springer][3])
* Claims to check before publishing: retain “probable arrow tips” or equivalent rather than implying that complete arrows were recovered; the arrow function rests on converging use-wear, fracture, residue and experimental evidence. ([PubMed Central (PMC)][2])
* Overstatement in the sources: the headline claim that the weapons were used “to slow down their prey” goes beyond what can be demonstrated for the Pleistocene examples. The study uses historically documented poisoned-arrow hunting as an analogy but explicitly states that the exact ancient weapon design and hunting strategy cannot be known. Boophone disticha is also identified as the most likely poison source rather than uniquely proven as the only possible plant. ([Smithsonian Magazine][1])
