GoKawiilFat is a very valuable food component, packed with calories, especially important when other resources might be scarce. Our earliest ancestors in Africa already cracked open bones to extract the fatty marrow from bone cavities. But now a new study published in Science Advances demonstrates that our distant cousins, the Neanderthals, pushed fat extraction from bones quite a bit further.

Neanderthal food strategies
The evidence comes from the Neumark-Nord 2 site in central Germany, dating back 125,000 years to an interglacial period when temperatures were similar to those of today. The site was situated in a lake landscape. 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. 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 findings, led by archaeologists from MONREPOS (Leibniz Zentrum Archaeology, Germany) and Leiden University (The Netherlands), in cooperation with the State Office for Heritage Management and Archaeology Saxony-Anhalt (Germany), indicate that Neanderthals operated what can be described as a prehistoric ‘fat factory’, carefully selecting a lakeside location to systematically process bones from at least 172 large mammals, including deer, horses and aurochs. These activities, previously believed to be limited to later human groups, now appear to have been part of Neanderthal behaviour as early as 125,000 years ago.

Landscape preservation
This discovery builds on decades of research at the ca. 30 ha large Neumark-Nord site complex already discovered in the 1980s by Jena archaeologist Dietrich Mania. From 2004 to 2009, the Neumark-Nord 2 site was excavated in year-round campaigns by a team led by MONREPOS and Leiden achaeologists. The excavations included a field school, which trained over 175 international students, including dozens of Leiden participants.
In 2023, the team published evidence that Neanderthals hunted and butchered straight-tusked elephants—up to 13-ton animals that could provide over 2,000 adult daily food portions. The use of fire to manage landscape vegetation and the diversity of processed species at different locations reveal a level of planning and ecological engagement previously underestimated in Neanderthals.
‘What makes Neumark-Nord so exceptional is the preservation of an entire landscape, not just a single site,’ notes Leiden-based author Prof. Wil Roebroeks. ‘We see Neanderthals hunting and minimally butchering deer in one area, processing elephants intensively in another, and – as this study shows –rendering fat from hundreds of mammal skeletons in a centralised location. There’s even some evidence of plant use, which is rarely preserved. This broad range of behaviours in the same landscape gives us a much richer picture of their culture.’
