Archaeologists Announce Major Neanderthal 'Fat Factory'
A team of archaeologists has announced a major finding relating to the Neanderthals. They announced the finding in the journal Science Advances. The scientists announced that they had discovered a "fat factory" at the edge of a German lake where they believe Neanderthals processed mammals for food 125,000 years ago. "We present archaeological data from the lake landscape of Neumark-Nord (Germany), where Last Interglacial Neanderthals processed at least 172 large mammals at a water's edge site," they wrote. "Their (partial) carcasses were transported to this location for the extraction of within-bone nutrients, particularly bone grease. This 'fat factory' constitutes a well-documented case of grease rendering predating the Upper Paleolithic, with the special task location devoted to extraction of nutritionally important lipids forming an important addition to our knowledge of Neanderthal adaptations," they added. According to the researchers, "These hunter-gatherers, similar to recent foragers, already focused heavily on the exploitation of within-bone nutrients—and particularly on bone grease—125,000 years ago." The time period in question was "an interglacial period when temperatures were similar to those of today," according to a news release on the findings issued by Universiteit Leiden. "At this location, researchers found that Neanderthals not only broke bones to extract marrow but also crushed large mammal bones into tens of thousands of fragments to render calorie-rich bone grease through heating them in water," the release says. "This discovery substantially shifts our understanding of Neanderthal food strategies, pushing the timeline for this kind of complex, labour-intensive resource management back in time tens of thousands of years." The researchers explained the importance of studying diet. "Diet played a key role in human evolution, making the study of past diet and subsistence strategies a crucial research topic within paleoanthropology," they wrote in the July 2 article. "Lipids are a crucial resource for hunter-gatherers, especially for foragers whose diet is based heavily on animal foods. Recent foragers have expended substantial amounts of energy to obtain this resource, including time-consuming production of bone grease, a resource intensification practice thus far only documented for Upper Paleolithic populations," they Announce Major Neanderthal 'Fat Factory' first appeared on Men's Journal on Jul 10, 2025

Neanderthals extracted animal fat in advanced food prep 'fat factories' 125,000 years ago: report
Neanderthals living 125,000 years ago in what is now modern-day Germany may have extracted and eaten fat from animal bones through an organized food preparation process that scientists describe as a "fat factory." While excavating the site of a former lake landscape called Neumark-Nord, archaeologists discovered thousands of bones from at least 172 large mammals, along with flint artifacts. The bones, which date back to an interglacial period in which Neanderthals lived, were from animals like red deer and horses, according to a study published on July 2 in Science Advances. While many of the bones that contained less bone marrow were spread out across the archaeological site, researchers observed that many of the marrow-rich bones were located in clusters — sites they call "fat factories." Rare Christian Cross Among Spectacular 1,000-Year-old Viking Treasures Found By Metal Detectorists Researchers believe our extinct ancestors used tools to smash the bones into small fragments and then boiled them for hours. The grease, which then floated to the surface of the water, could be skimmed off the top and eaten — providing a calorie-dense food source for the archaic people.

125,000-year-old ‘fat factory' run by Neanderthals discovered in Germany
An AI-generated impression of what the fat factory site may have looked like 125,000 years ago. (Scherjon/LEIZA-Monrepos via CNN Newsource) Stone Age humans living by a lake in what's now Germany systematically processed animal carcasses for fatty nutrients — essentially running what scientists describe as a 'fat factory' to boil bones on a vast scale, according to new research. Archaeologists uncovered the factory by analyzing some 120,000 bone fragments and 16,000 flint tools unearthed over several years at a site known as Neumark-Nord, south of the city of Halle, they reported in a study published Wednesday in the journal Science Advances. Excavators found the artifacts alongside evidence of fire use. The researchers believe that Neanderthals, an extinct species of human known to have lived in that area as far back as 125,000 years ago, smashed the marrow-rich bones into fragments with stone hammers, then boiled them for several hours to extract the fat, which floats to the surface and can be skimmed off upon cooling. Since this feat would have involved planning hunts, transporting and storing carcasses beyond immediate food needs, and rendering the fat in an area designated specially for the task, the finding helps paint a picture of the group's organization, strategy and deeply honed survival skills. 'This attitude that Neanderthals were dumb — this is another data point that proves otherwise,' said Wil Roebroeks, study coauthor and professor of Paleolithic archaeology at Leiden University in the Netherlands. A string of archaeological discoveries in recent decades have showed that Neanderthals were smarter than their original brutish stereotype might suggest. The ancient humans lived across Eurasia and disappeared 40,000 years ago, and previous studies have found they made yarn and glue, engraved bones and cave walls, and assembled jewelry from eagle talons. Details in the new research suggest that Neanderthals may have been unexpectedly sophisticated in their approach to nutrition, too. Threat of protein poisoning The Neanderthals living at the German site over a 300-year period also clearly understood the nutritional value of the bone grease they produced, according to the study. A small amount of fat is an essential part of a healthy, balanced diet. The substance was even more essential for hunter-gatherers, such as Neanderthals, who likely depended heavily on animal foods. A diet dominated by lean meat and deficient in fatty acids can lead to a debilitating and sometimes lethal form of malnutrition, in which the capacity of liver enzymes to break down the protein and get rid of excess nitrogen is impaired, the researchers noted in their paper. Known today as protein poisoning, the condition earned a reputation among early European explorers of North America as 'rabbit poisoning' or 'mal de caribou.' Hunter-gatherers such as Neanderthals, with average body weights between 50 kilograms and 80 kilograms (110 pounds and 175 pounds), would have had to keep their consumption of dietary protein below 300 grams (about 10 ounces) per day to avoid the condition. That amounts to around 1,200 calories — a level of intake far short of daily energy needs, according to the research. As a result, the Neanderthals likely needed to source the remaining calories from a nonprotein source, either fat or carbohydrate. Cuts of meat from animal muscle contain very little fat, making bones — which contain marrow and other fatty tissue even when an animal is malnourished — a more important resource. The researchers discovered that the overwhelming majority of remains at the site came from 172 individual large animals, including horses, deer and aurochs, large cow-like creatures that are now extinct. Neanderthals had selected the longest bones that would have contained the most marrow, the study found. Neanderthal fat factory The archaeological site in Germany was excavated from 2004 to 2009. (Roebroeks/Leiden University via CNN Newsource) A dash of acorn, a pinch of sloe plum Exactly how the Neanderthals processed the bones isn't clear, according to the study authors. The ancient humans likely fashioned containers or pots from birch bark, animal skins or other body parts such as stomach linings, filling them with water and hanging them over a fire, Roebroeks said. Neanderthals could have consumed the fat they produced as a 'greasy broth' to which plants may have been added for flavor as well as nutritional value, suggested study coauthor Geoff Smith, a senior researcher in zooarchaeology at the University of Reading. The charred remains of hazelnut, acorn and sloe plum were also found during the excavations, he noted. 'These weren't simple hunter-gatherers just getting by day to day — they were master planners who could look ahead, organise complex tasks, and squeeze every last calorie from their environment,' Smith said. The findings are 'exciting,' according to Ludovic Slimak, an archaeologist at the French National Centre for Scientific Research (CNRS) and Paul Sabatier University in Toulouse, France. Slimak wasn't involved in the study. Neanderthal fat factory Researchers believe that Neanderthals smashed animal bones into fragments before boiling them to extract the nutrients. (Kindler/LEIZA-Monrepos via CNN Newsource) 'They finally offer clear archaeological confirmation of what many of us had long suspected: that Neanderthals not only valued within-bone lipids but developed specific strategies to extract and process them,' said Slimak, who is the author of the 'The Last Neanderthal,' which will be published in English later this year. 'This aligns closely with the broader archaeological record, which shows Neanderthals as highly skilled big-game hunters with a refined sense of ecological adaptation,' he added. The Neumark-Nord site is 'the best example yet of bone-grease rendering,' from this period of the Stone Age, said Bruce Hardy, the J. Kenneth Smail Professor of Anthropology at Kenyon College in Gambier, Ohio. Hardy also was not involved in the research. 'The combination of evidence presented here at Neumark-Nord is impressive,' Hardy said. 'It may well represent the smoldering gun, or simmering bone broth, of Neanderthal bone-grease rendering.'
