In 1993, a group of cave explorers in southern Italy stumbled upon a human skeleton stuck in a cave wall near the town of Altamura. The man, now called the Altamura Man, was a Neanderthal who lived between 130,000 and 187,000 years ago. He likely fell into a deep sinkhole, got trapped, and died there, his body slowly covered by calcite deposits that formed over thousands of years.
Background
The Lamalunga Cave system sits about three kilometers from Altamura, a small city in Italy's Puglia region. This area has a lot of karst formations, which are caves and tunnels created by water dissolving limestone over time. Explorers from a local group called CARS had to climb down a 10-meter swallowhole and crawl through narrow passages to reach the spot. They found the skeleton encased in thick layers of calcite, the mineral that makes up cave formations like stalactites.
Neanderthals lived across Europe and parts of Asia from about 400,000 to 40,000 years ago. They shared the world with early modern humans for thousands of years and even interbred with them. Many people today of non-African descent carry about 2 percent Neanderthal DNA. The Altamura Man stands out because his skeleton is one of the most complete ever found. Most Neanderthal remains are fragments, but his body stayed mostly intact due to the cave conditions.
Early studies confirmed he was an adult male with typical Neanderthal traits, like a wide nasal opening and a face that projects forward. These features puzzled scientists for decades. Neanderthals lived through Ice Age cold, so experts thought their large noses helped warm and moisten cold air before it reached the lungs. But the outer nose shape did not match what cold-adapted animals usually have.
Over the years, teams have visited the cave multiple times. In the 2000s and 2010s, they used cameras and tools to look behind the calcite without touching the bones. They found loose bits of bone, like parts of the shoulder blade, which helped date the remains. Calcite layers formed in stages, starting around 130,000 years ago, with older formations nearby from 172,000 to 180,000 years ago. This pins the man's death to that wide time range in the Middle-Upper Pleistocene.
Paleogenetics, the study of ancient DNA, has also been done on small samples. It shows he is the oldest Neanderthal from whom scientists extracted genetic material. This DNA helps trace how Neanderthals spread and mixed with other groups.
Key Details
The Altamura Man's skull and bones are covered in coralloid calcite, which looks like popcorn. This preserved delicate parts, including the inside of his nose. A recent study used endoscopes—small cameras on flexible tubes—to peer into the nasal cavity without removing the fossil.
Nasal Structures and Cold Adaptation
The internal nose shows no special features that would help fight cold air, as some theories suggested. Neanderthal faces have a wide nose opening and forward projection, called midfacial prognathism. Scientists once thought hidden internal changes, like twisted passages, compensated for the outer shape in cold climates. But the Altamura fossil proves those ideas wrong. The nose matches what you see on the outside, with no extra twists or flaps.
His teeth tell another story. He had almost a full set of 42 teeth, which is rare for fossils this old. They were in good shape overall, but he had dental calculus—hardened plaque—and exposed roots from gum disease. This suggests he ate a varied diet, maybe including plants and cooked food, common for Neanderthals.
The skeleton is still in the cave because moving it could damage it. The calcite holds it together like glue. Researchers have used X-rays, high-res photos, and videoscopes from the cave floor. They even spotted a small chamber behind him with more bone fragments.
“Neanderthal faces have been interpreted through the lens of climate for so long that alternative explanations were rarely given room to breathe,” says Dr. Elisa Montalbán, a paleoanthropologist at the University of Barcelona. “The Altamura specimen finally provides direct evidence that challenges those climatic assumptions.”
Forensic looks at his jaw show signs of heavy use, fitting for a hunter-gatherer life. His ancestors came from central Europe and Asia hundreds of thousands of years earlier.
What This Means
This find changes how we think about Neanderthal evolution. The nose study, published in a top journal, shows their facial features likely came from how their skulls grew, not just cold weather. This opens doors to other explanations, like diet, breathing patterns, or even speech.
It also highlights why Neanderthals matter for human history. They adapted to tough environments, used tools, buried their dead, and painted caves. Learning from Altamura could explain why they vanished around 40,000 years ago, even as modern humans spread.
Keeping the fossil in place preserves it, but limits study. Extraction might yield DNA for full genome sequencing, diet details, and diseases. Experts compare it to Otzi the Iceman, a 5,300-year-old mummy studied in labs for decades. If removed safely, Altamura could become the top Neanderthal specimen.
Right now, access is restricted to protect the site. No public visits, and research needs special gear for the dark, tight spaces. Ongoing work combines morphology—the study of bone shapes—with genetics to paint a fuller picture of this man and his kind.
The Altamura Man bridges a gap in our family tree. His preserved state lets scientists test old debates with hard evidence. As tools improve, more secrets from his tomb could reshape stories of human origins.
