The most complete Neanderthal skull ever examined has given researchers something they have never had before: a virtually untouched internal nose. That rare anatomical jackpot is forcing a rethink of why Neanderthals evolved such prominent faces and what those features really say about life in Ice Age Europe. Instead of a simple story about survival in the cold, the new evidence points to a more complex balance of breathing, chewing, and sheer evolutionary contingency.
The fossil, known as Altamura Man, preserves the inner nasal cavity in extraordinary detail, allowing scientists to peer inside a Neanderthal face without guesswork or heavy reconstruction. By combining endoscopic cameras, digital scans, and advanced modeling, the research team has turned this skull into a test case for long standing assumptions about Neanderthal biology, from how they warmed the air they breathed to how they powered their massive jaws.
Inside the cave with Altamura Man
Altamura Man lay hidden in an Italian cave for well over a hundred millennia, his bones encased in mineral deposits that both trapped and protected them. Researchers estimate that this Neanderthal died somewhere between 130,000 and 172,000 years ago, a span that places him deep in the Middle Pleistocene, long before our own species spread across Europe. The unusual geology of the cave effectively sealed the skeleton in place, preserving not only the outer contours of the skull but also the delicate inner structures that usually crumble or erode.
That geological accident has turned Altamura Man into a kind of anatomical time capsule. Instead of working from scattered fragments, scientists can study a Neanderthal face that is still largely in situ, with the nasal cavity, sinuses, and mid facial bones held in their original relationships. One research team described the fossil as so well preserved that it provides unprecedented information about Neanderthal nasal anatomy, a level of detail that simply did not exist in the human fossil record until now.
The first intact Neanderthal nose
For decades, paleoanthropologists have had to infer Neanderthal nasal anatomy from partial skulls and external features, reconstructing the inner cavity from the outside in. Altamura Man changes that, because his skull contains what researchers describe as the only intact inner nose bones of a Neanderthal yet discovered. An analysis of these structures shows that the internal nasal cavity is preserved in three dimensions, from the turbinates to the septum, giving researchers a direct look at airflow pathways rather than a speculative model.
To access that anatomy without destroying the fossil, the team threaded tiny cameras into the skull and paired those images with high resolution digital scans. Using endoscopic probes, they captured the internal contours of the nasal cavity and then built a detailed 3D reconstruction that could be rotated, sliced, and measured on screen. One account of the work notes that using endoscopic probes allowed the researchers to document the inner nasal structures in situ, confirming that Altamura Man’s internal nose was neither simply a scaled up version of ours nor a straightforward adaptation to extreme cold.
How scientists digitally rebuilt a Neanderthal face
Once the internal nose was mapped, the next step was to integrate those data into a full facial reconstruction. Scientists combined endoscopic imagery, CT style scans, and surface photogrammetry to create a digital model of the skull that could be analyzed from every angle. A report on this work explains that a digital analysis of the intact skull allowed the team to test how different facial traits, including the nose, related to each other rather than treating each feature in isolation.
That digital workflow matters because it lets researchers run experiments that would be impossible on the physical fossil. They can simulate how air would move through the nasal cavity, how stresses from chewing would travel through the mid face, and how small changes in bone shape might alter both. One overview of the project notes that the unusual skull has already reshaped what we know about Neanderthal faces, with the internal nasal cavity emerging as a key piece of the puzzle in how we know about their faces and the forces that shaped them.
Challenging the “built for the cold” nose myth
For years, textbooks and museum displays have treated the Neanderthal nose as a textbook example of adaptation to frigid climates, a kind of natural radiator that warmed and humidified icy air before it reached the lungs. The new work on Altamura Man directly tests that idea by comparing the shape of his internal nasal cavity with models of airflow and heat exchange. According to one summary, the study explicitly challenges the long held view that Neanderthal noses were primarily adapted for the cold, arguing instead that their internal architecture does not match what would be expected if warming air were the main evolutionary pressure.
Other coverage of the research reaches a similar conclusion, noting that the most intact Neanderthal yet studied indicates their large noses were not primarily built for the cold in the way many scientists once assumed. Instead, the internal nasal cavity appears to reflect a compromise between breathing efficiency and the structural demands of a powerful face, suggesting that climate was only one factor among several that shaped Neanderthal nasal form.
What the “perfect condition” nose reveals about breathing
Altamura Man’s nose is not just intact, it is described as being in almost perfect anatomical condition, which makes it an ideal test bed for studying Neanderthal respiration. One account of the discovery highlights that Scientists Just Found a Neanderthal Skull with Its Nose in Perfect Condition, and that this rare preservation allows researchers to model how air would have flowed through the nasal passages during heavy exertion, rest, and different environmental conditions. Those simulations suggest that Neanderthals could move large volumes of air efficiently, which fits with a lifestyle that demanded intense physical effort.
The internal nasal cavity also provides the first preserved nasal cavity in the human fossil record that can be used to rigorously model respiratory performance. The formal description of the work emphasizes that this fossil represents evidence hitherto unavailable for both Neanderthals and humans in general, and that it offers a new foundation for modeling Neanderthal respiratory performances. In practical terms, that means scientists can now compare how efficiently Neanderthals and modern humans might have ventilated their lungs, how they coped with cold or dry air, and how their breathing systems supported their muscular builds.
Rewriting the story of Neanderthal faces
Once the cold adaptation narrative is set aside, the question becomes what actually drove the evolution of the Neanderthal face. The new analyses point toward a more integrated explanation in which chewing forces, braincase shape, and nasal airflow all interact. A detailed report on the fossil notes that this Neanderthal skull suggests that the shape of the nose was influenced not only by the need to condition air, but by other factors such as the mechanics of the mid face and the demands of a heavy bite. In that view, the prominent Neanderthal nose is less a single purpose tool and more a structural hub that helps the face handle multiple jobs at once.
Other coverage underscores how unusual it is to have a Neanderthal skull that preserves both external and internal facial features in such detail. One account describes the fossil as the most intact Neanderthal ever found, and another notes that the astonishingly well preserved nasal cavity in Italy has effectively settled one of the great debates in human evolution about whether Neanderthal faces were primarily shaped by climate or by other functional demands. The emerging consensus from these studies is that Neanderthal facial anatomy cannot be reduced to a single environmental story, and that their distinctive noses are best understood as part of a broader, integrated cranial design.
What Altamura Man means for our own evolution
Altamura Man’s nose is not just a curiosity about a long vanished cousin, it is a new reference point for thinking about our own species. By comparing the internal nasal cavity of this Neanderthal with that of modern humans, researchers can test how different facial architectures handle the same basic tasks of breathing, smelling, and speaking. One synthesis of the findings notes that the fossil provides only intact inner nose bones known for a Neanderthal, which makes it a crucial benchmark for any future comparisons with early Homo sapiens skulls.
As more digital models of ancient faces accumulate, Altamura Man will likely serve as a template for how to integrate internal and external anatomy into a single evolutionary story. The work on this fossil has already shown that long standing assumptions about Neanderthal noses can fall apart when confronted with high resolution data, and it hints that other familiar narratives about human evolution may face similar revisions once equally detailed evidence comes to light. For now, the remarkably intact nose inside this skull has given scientists their first clear look at how a Neanderthal really breathed, and in doing so, it has quietly redrawn one of the most recognizable faces in our deep past.
