Shanidar Cave Cold Case: Was a Neanderthal Killed by a Spear?

High on Bradost Mountain in the Kurdistan Region of Iraq, a cave mouth opens like a giant eye over the valley below. For tens of thousands of years, Neanderthals came back to this spot. They sheltered here, cooked here and, behind a tall rock near the entrance, buried their dead. One of those burials has now become the oldest cold case anyone has tried to crack.

The victim is a Neanderthal researchers call Shanidar A. The cause of death, according to a study published Oct. 15, 2026, in the journal Scientific Reports, appears to be a wooden spear driven into the chest from the front. The weapon is long gone. The killer, if there was one, will never be named. What survives is a single small hole in a shoulder blade, and a fierce scientific argument over what made it.

The Shanidar Neanderthal at the Center of the Case

Shanidar A was about 45 years old at death. The study team could not determine the individual’s sex from the bones recovered. Those remains came out of the ground during excavations in 2019 and 2022, according to CNN: a shoulder blade, most of a right hand, several ribs and a handful of teeth.

The shoulder blade lay about 7.5 meters, or roughly 24 feet, below the surface. The burial is dated to roughly 75,000 years ago, placing this Shanidar Neanderthal in the Middle Paleolithic.

The paper, titled “Evidence for funerary behaviour and lethal trauma in a new Neanderthal individual from Shanidar Cave,” was led by Emma Pomeroy of the University of Cambridge. Co-author Graeme Barker, also of Cambridge, is part of the team working at the cave. The full study is available through its journal listing.

The Wound: A Perfect Circle in Bone

The key evidence is a round hole, about 15 millimeters across, near the edge of the left shoulder blade. A disc of bone had been punched clean out. The researchers found no sign of healing, meaning the injury happened at or very near the moment of death.

The team checked for the usual suspects that damage ancient bone after burial. They ruled out animal gnawing and insect burrowing, according to Live Science. That left penetrating trauma: something pointed, moving fast, entering the body from the front.

The shape mattered most. Experimental wounds made with stone-tipped spears tend to leave angular or diamond-shaped holes. A sharpened wooden point leaves something rounder. Shanidar A’s wound matched the wooden spear profile, and the diameter of the hole fits the width of a spear shaft just behind the point.

If the reconstruction is right, the weapon passed through the lung and near major arteries. Death would have come quickly. Pomeroy told reporters the wound’s position and force carry the “hallmarks of an intended kill shot directed towards the heart.” She also acknowledged that the exact events cannot be known.

A Life of Injury, and of Care

The spear wound was not the only trauma Shanidar A suffered. One lower front tooth had split during life. Hardened plaque had built up over the broken edge, which means the individual kept living and eating with that damage for at least a year, and likely longer.

The researchers believe the split tooth points to an earlier blow to the face, one that may have injured the jaw as well. Surviving that kind of injury in the Ice Age would not have been easy. The team suggests group members likely softened food and helped with eating, drinking and communication during recovery.

That detail turns the story from a simple whodunit into something more human. Shanidar A appears to have been cared for after one injury, then killed by another, then carefully buried. The same people, or people like them, were capable of both tenderness and lethal force.

It fits a growing body of evidence on Neanderthal care. Shanidar Cave already produced a male Neanderthal who, according to a 2017 study, was deaf, partly blind and paralyzed in one arm, yet lived to roughly 50 or 60. Other sites have yielded signs that Neanderthals cared for a child with Down syndrome.

A Burial Behind the Rock

Where Shanidar A ended up adds to the mystery. The body was placed behind a large rock, about two meters high, that separated this corner from the cave mouth. Over the following years or decades, at least four more Neanderthals were laid in the same small space, including an infant, ABC News in Australia reported.

Repeated burials in one tight spot suggest the place itself meant something. Archaeologists have long debated whether Neanderthals had funeral customs. The Shanidar evidence keeps pushing the answer toward yes.

The cave is no stranger to big claims. In the 1950s and 1960s, excavations led by American archaeologist Ralph Solecki uncovered Neanderthal remains with clumps of ancient pollen nearby. The find gave rise to the famous “flower burial” story, which painted Neanderthals as mourners who laid blossoms on their dead. Pomeroy’s team, which reopened the site in 2015, now believes the pollen was most likely carried in by burrowing bees much later.

The First Shanidar Stabbing

Shanidar A is not the first Neanderthal from this cave with a suspicious wound. Shanidar 3, an older male who died roughly 50,000 years ago, had a deep cut in one of his ribs. A 2009 study argued that wound was most consistent with a stone-tipped projectile and raised the possibility that it was thrown by an early modern human.

That makes two Shanidar Neanderthals, separated by about 25,000 years, with signs of being speared. Pomeroy has said the pairing may simply be coincidence. Still, the coincidence keeps the cave at the center of one of the oldest questions in human history: how violent were our ancient relatives, and who were they fighting?

Evidence of deliberate killing in the deep past is rare. Most injuries found on Middle Paleolithic skeletons are linked to likely accidents, such as hunting mishaps or falls. One older exception comes from Sima de los Huesos in Spain, where forensic study of skulls points to intentional lethal violence about 430,000 years ago, though the weapon there is unknown.

For readers who follow ancient violence, Stucci Media recently covered skulls from Egypt’s first royal tombs that tell their own grim story, and the first intact graves found at Göbekli Tepe.

Murder, War or Accident?

Even if a wooden spear made the hole, it does not answer the bigger question. A spear in the chest could mean a fight between two Neanderthals. It could mean a raid by a rival group. It could also mean a tragic accident during a hunt, when several people were throwing or thrusting weapons at the same animal.

John McNabb, an emeritus archaeologist at the University of Southampton who was not involved in the study, told CNN that a wound through the shoulder while facing the victim supports deliberate violence. Whether it was murder or an attack by outsiders, he said, “We just do not know.”

The study does not name a likely attacker, Neanderthal or otherwise. The researchers are still excavating later layers of the cave, including the period when Homo sapiens began using the site, which may add context in the years ahead.

What Skeptics Say

The study has drawn real pushback, and the strongest objections are worth laying out plainly.

The weapon is missing. No spear was found. Wood rarely survives tens of thousands of years, so the spear theory rests entirely on the shape and size of the hole. Sofia Samper Carro of the Australian National University, who was not involved in the research, told ABC News some conclusions are “a bit of a stretch” without more evidence.

Round holes in bone are unusual. Samper Carro also noted that bones usually break in linear fractures. A clean circle is strange, which cuts both ways. It makes the wound distinctive, but it also means there are few good comparisons.

An animal could have done it. Rebecca Wragg Sykes, an archaeologist and author who studies Neanderthals, told Live Science a spear is plausible but suggested testing whether a wild goat horn could make the same wound. Wild goats were the most heavily hunted animal at Shanidar, so a goring during a hunt is a reasonable alternative.

Intent cannot be read from bone. Even the authors concede a hunting accident remains possible. A “kill shot” is a description of where the weapon landed, not proof of what was in anyone’s mind.

The team plans experiments to measure how much force it takes to make a wound like this one. Those results could help separate a deliberate thrust from an accident or an animal strike.

Why It Matters

The Shanidar Neanderthal case grips people for the same reason any cold case does. Someone died violently, someone else buried them with care, and the full story was swallowed by time. We are left with a few clues and a lot of questions.

It also changes how Neanderthals are pictured. For a century, they were cast as brutish cave dwellers, as in early museum paintings. Shanidar keeps complicating that image. These were people who nursed the injured, returned to the same burial spot for generations and, apparently, faced violence that could end a life in an instant.

Wooden spears are among the oldest known weapons. Spears between 200,000 and 400,000 years old have been found in Europe, including the famous finds at Schöningen in Germany. Shanidar A may be the oldest known victim of one. That puts a face, or at least a shoulder blade, on the weapon that carried our ancestors and their cousins through the Ice Age.

The cave still has more to give. As excavators dig into later layers, they may find out whether Neanderthals and early modern humans ever met at Shanidar, and how those meetings went. For more stories like this, explore Stucci Media’s Historical Events and Analysis section.
