Archaeologists Were Digging Into a Hill—and Stumbled Upon a 125,000-Year-Old Factory
Here's what you'll learn when you read this story: A new study shows evidence of Neanderthal 'fat factories' dating back as far as 125,000 years ago. The study found inhabitants of the settlement strategically selected the lakeside location for the factory and harvested bone marrow by breaking open the bones as well as through a process of crushing and heating. The fat factory suggests Neanderthals' grasp of their survivalist diets, and that they were able to understand their environment and plan ahead for hunting and resource-gathering. Though the assembly line is largely credited to Henry Ford in 1913, humans understood the mass production practice long beforehand. A new study published in the journal Science Advances shows that the Neanderthals—our distant cousins—operated 'fat factories' to extract bone marrow for their diets as far back as 125,000 years ago. The recent research from Leiden University adds to decades of previous research at the Neumark-Nord archaeological site near Leipzig, Germany. Around 125,000 years ago, Earth experienced an interglacial period with weather much like our climate today. Previous research at Neumark-Nord showed that Neanderthals hunted and butchered straight-tusked elephants in the region. According to a press release from Leiden University, there is also evidence of plant use in the area, though it's rarely preserved. Additionally, previous studies found proof that inhabitants used fire to manage vegetation. Needless to say, Neanderthals have long been underestimated, and the new study does nothing to dissuade that notion. Archeologists on the recent excavation found that Neanderthals intentionally selected the lakeside location to process the bones of at least 172 mammals including deer, horses, and aurochs (a now-extinct species of bovine). According to the study, inhabitants at the site not only broke open large mammal bones to extract the marrow, but they also ground the bones into thousands of fragments and heated them in water to extract calorie-rich bone grease. These findings place estimates of advanced resource collection thousands of years earlier than previously thought. 'This was intensive, organised, and strategic,' the study's first author Lutz Kindler said in the press release. 'Neanderthals were clearly managing resources with precision—planning hunts, transporting carcasses, and rendering fat in a task-specific area. They understood both the nutritional value of fat and how to access it efficiently—most likely involving caching carcass parts at places in the landscape for later transport to and use at the grease rendering site.' Experts believe Neanderthals understood that there was a certain 'fat quota' they had to meet in order to make the (literally) bone-crushing process worthwhile. The authors of the paper emphasized the transparent amount of herbivores that Neanderthals at Neumark-Nord must have been hunting, explaining that our 'cousins' were likely able to plan ahead and use their environment effectively. This extensive research was possible because it wasn't just one site that was preserved—it was an entire landscape, according to the authors of the study. 'The enormous extent and exceptional preservation of the Neumark-Nord site complex offers us a unique opportunity to investigate how Neanderthals influenced their environment—both flora and fauna,' Fulco Scherjon, researcher on the project, said in the release. 'This is extremely rare for such an ancient site—and opens exciting perspectives for future research.'

125,000-year-old 'fat factory' run by Neanderthals discovered in Germany
When you buy through links on our articles, Future and its syndication partners may earn a commission. Neanderthals were running a potentially lifesaving "fat factory" around 125,000 years ago in what is now Germany, a new study finds. The research, published Wednesday (July 2) in the journal Science, reveals that these archaic human relatives had a process for extracting grease from animal bones — and it may have saved them from a lethal condition. The condition, known as protein poisoning or rabbit starvation, happens when humans eat too much protein and don't get enough fat or carbohydrates. Neanderthals would have likely been at high risk of protein poisoning, as they largely ate meat. The "fat factory" discovery suggests that hominins, or humans and our close relatives, were practicing resource intensification — getting more utility out of the materials they had available — much earlier than previously thought. Before this analysis, the earliest evidence for resource intensification dated to 28,000 years ago, long after the Neanderthals' extinction, according to the study. Scientists found the Paleolithic factory after uncovering the fragmented remains of 172 large animals, including horses, deer and cattle, as well as Neanderthal-made anvils and hammerstones. After analyzing the bones, the team found that Neanderthals had first smashed the bones to get to the marrow — a soft, edible tissue inside of some bones — before boiling them to extract the fat. It appears that Neanderthals ate both the marrow and the fat, which would have maximized the amount of food and nutrients they got from an animal carcass. "It's surprisingly creative and innovative behavior from Neanderthals," Osbjorn Pearson, an archaeologist at The University of New Mexico who was not involved in the study, told Live Science. Related: 10 fascinating discoveries about Neanderthals in 2024, from 'Thorin' the last Neanderthal to an ancient glue factory Neanderthals, the closest extinct relative of modern humans, emerged around 400,000 years ago and went extinct around 34,000 years ago. Remains of the archaic humans were first discovered in the 19th century, and much of the archaeological evidence revealed since then suggests that Neanderthals were fairly sophisticated. They made tools, glue factories and possibly even art. While it was known that Neanderthals largely ate meat, little was known about how Neanderthals prepared animal carcasses. "We know a lot about Neanderthal hunting tactics, habits and consumption of meat and bone marrow … but to much lesser degree about all the processes after hunting and butchering," study first author Lutz Kindler, an archaeologist at the Monrepos Archaeological Research Center and Museum for Human Behavioral Evolution in Germany, told Live Science in an email. Archaeologists found 2,000 bone fragments at Neumark-Nord, an archaeological site in central Germany, that had been crushed to facilitate the grease extraction. "Fragmentation of the bones of large mammals into such a vast amount of small fragments is labour-intensive and time-consuming," so it's clear they served a purpose, study co-author Wil Roebroeks, a professor emeritus of paleolithic archaeology at Leiden University in the Netherlands, told Live Science in an email. In addition to bearing signs of being boiled, the bones are mostly broken near areas that contain the most fat, which supports the idea that the grease was rendered for consumption. Neanderthals might have eaten the fat out of necessity, Pearson said. They sometimes experienced periods of starvation and may have been desperate for sources of calories. "And it turns out that fat is just packed with calories," he said — fat supplies more than twice the calories per gram as carbohydrates and protein do. The bones also suggest that these archaic humans may have used some form of food storage, Roebroeks said. Neanderthals may have been "more similar to historically documented foragers" than previous research had suggested, he added.

"The archaeological science of studying hominids is about finding the similarities between us today and them in the past," he said. Understanding what Neanderthals ate and how they acquired it may improve our understanding of human adaptations, Roebroeks said. The extra calories provided by bone-derived grease has been vital to human evolution, as more robust diets can lengthen lifespan and lead to increased reproduction.

Oldest known human fingerprint discovered on ancient Neanderthal artwork – with help from Spain's forensic police
A unique archaeological find has recently expanded our knowledge of Neanderthals' capacity for symbolic thought. The object in question is a granite stone, on which a red ochre dot was deliberately applied to reinforce the image of a human face. It is, to date, the oldest example of portable art associated with Neanderthals. The most remarkable aspect of this discovery was the identification of a fingerprint in the pigment, at a level we have unequivocally dated to more than 42,000 years ago. The fingerprint means the find is direct evidence of a symbolic action that we can attribute to a Neanderthal human (Homo neanderthalensis). This discovery is the fruit of over two years of research, and was published in May 2025 in Archaeological and Anthropological Sciences. In addition to the team of archaeologists and geologists, our paper was co-authored by members of the Central Identification Unit of the General Commissary of Scientific Police, whose contributions were vital to the work's success. The red-spotted stone was found at the Abrigo de San Lázaro archaeological site – in the Eresma river valley, downstream from the Spanish city of Segovia – where we found remains of occupations of the last European Neanderthals. The stone was in a level where we have previously found Mousterian (Middle Paleolithic) industry. These are stone tools clearly associated with Neanderthal occupations, such as those documented in the known areas of Abrigo del Molino and other nearby sites. In our study, we hypothesise that the object was chosen and collected from the riverbed because of its peculiar natural features. Put simply, it looks like a human face. Facial pareidolia, the psychological phenomenon whereby we perceive faces in inanimate objects, identifies the upper and lower indentations as eyes and a mouth in the stone. The application of red pigment to make a nose reinforces the perception of a face, and acts as a symbolically charged visual marker. The possibility that we are dealing with a symbolic representation of a human face adds a particularly significant interpretative dimension to the archaeological find. Leer más: One of the most remarkable aspects of this research was its cross-disciplinary collaboration between archaeologists, geoarchaeologists and members of the General Commissary of the Spanish Scientific Police. To reach our conclusions, a combination of techniques were applied to the object. First, we performed detailed 3D mapping using high-precision scanners and digital models, which helped to rule out that the stone had served any any functional purpose, such as that of an anvil or hammer. We then carried out non-invasive analyses, such as X-ray fluorescence and scanning electron microscopy. The results confirmed that the red pigment was externally applied ochre, as opposed to a natural mark resulting from the decomposition of minerals in the granite itself. But the most surprising breakthrough came from multispectral analysis. This is a well-known technique that the Spanish General Commissary of Scientific Police developed and adapted specifically for the study of the stone. By using this method, Samuel Miralles Mosquera, a forensic imaging expert, revealed a fingerprint that was invisible to the naked eye, printed directly into the pigment. The image was later analyzed by M° Carmen Sastre Barrio, Encarnación Nieva Gómez, M° Remedios Díaz Delgado and Elena Ruiz Mediavilla, identification specialists of the same team. They confirmed that it matched the fingerprint of an adult human male. Their work allowed for the identification of the fingerprint with a previously unprecedented level of detail in the context of Paleolithic study. Their help made the research a pioneering reference in the field of applying archaeology and forensic identification to prehistoric times. It provides a new window on the symbolic world of the Neanderthals, and opens new avenues for the study of their artistic expression, their visual sensitivity and their capacity for abstraction. Combining these scientific techniques reinforces the authenticity of the find, and underlines its exceptional nature. It is one of the most complete physical testimonies of a symbolic act performed by a Neanderthal, whose fingerprint was deliberately left in the pigment. Who would have imagined that, more than 40,000 years later, not even Neanderthals could escape being identified by forensic scientists. Leer más: The origin of humans' symbolic behaviour – and with it the emergence of art itself – is one of the most hotly debated questions in research on humankind's cognitive evolution. While both phenomena did not emerge simultaneously, they are deeply interconnected, since the capacity for symbolic thought is ultimately the foundation of all forms of artistic expression. For decades, it was claimed that this ability was exclusive to 'modern' or present-day human beings (Homo sapiens). However, the development of new methodologies and the discovery of increasingly solid evidence have challenged this view to the point of refuting it. There is now a growing consensus that Neanderthals also possessed a complex symbolic repertoire, manifested through modified objects, use of pigments, ritual behaviours and other unambiguously symbolic expressions. One of the key milestones in this shift in opinion was the publication – in the journal Science in 2018 – of the dating of several cave paintings found in three Spanish caves: Ardales, La Pasiega and Maltravieso. These were the first paintings with a symbolic character attributed to Neanderthals. They included simple, geometric shapes, including discernible patterns. Their study revealed the ability of this human group to deliberately generate symbolic images charged with shared meaning. While the representations are simple, they appear repeatedly in different places on the walls of the caves. To this list of findings, we can now add the work of another anonymous Neanderthal. This male, one of Europe's last Neanderthal inhabitants, saw a face on a rock collected from the river, intentionally painted a red dot with ochre, and left his mark on history.
