Dozens Of Curious Bones Modified Into Cups And Masks Discovered At Neolithic Sites In China
Sawada et al. 2025One of the skulls analyzed during the study has two perforations and appears to be highly polished.During a study of almost 200 human bones from Chinas Neolithic Liangzhu culture, researchers made a surprising discovery: Several dozen of them showed some kind of modification. The bones had been perforated, split, ground down, or polished. Though seemingly discarded before completion, some formed skull masks, while others were crafted into skull cups. Many questions remain about this curious find, but researchers suspect that the modified bones are related to prehistoric rituals and changing attitudes toward death in increasingly urban settings. The Bones Of The Neolithic Liangzhu CultureAccording to a study published in Scientific Reports, 183 bones were discovered during studies at Neolithic Liangzhu culture sites in southern Chinas Yangtze River Delta. The bones date back to between 5,300 and 4,500 years ago, and 52 of them had seemingly been modified in some way. Interestingly, the researchers wrote in their study, many of them show evidence of working, such as splitting, grinding, perforating, and polishing.Scientific Reports One of four skulls that was seemingly modified into a mask.The prehistoric bones had been modified into skull cups, masks, and plate shapes. Some skulls had perforations, jaw bones had flattened bases, and limb bones showed signs of having been flattened, cut, or cracked. Several had seemingly been highly polished. The bones belonged to a wide range of ages and sexes researchers discovered remains from both men, women, and children. And the bones, lacking cut marks, were seemingly harvested long after death.There were no signs of violence, no cut marks on the bone surface that could be interpreted as disarticulation marks, and no evidence of burning, the researchers wrote in their study.Yet, most of the bone items were apparently discarded before they were finished. The researchers noted that 80 percent were seemingly incomplete when they were tossed into nearby canals and moats. Scientific ReportsSkulls that were seemingly modified into plates.This high proportion prompts several questions regarding the reasons for abandonment, the researchers wrote. Were these items left unfinished due to technical failure? Did their incompleteness carry ritual or symbolic meaning? Or was production interrupted due to shifting social priorities?For now, many questions about the modified bones remain. But researchers have some ideas about who they may have belonged to and what purpose they may have served.The Mysterious Purpose Of The Neolithic Liangzhu BonesChinas Liangzhu culture emerged around 5,300 to 4,500 years ago along the Yangtze River Delta. Its one of the earliest and largest walled urban societies in the country. Liangzhu settlements are quite sophisticated, with cemeteries, dams, canals, altars, workshops, and palaces. So, why did its people modify bones and then discard them? Scientific ReportsSkulls modified to make what appear to be cups.Because the Liangzhu culture left no written record, the answer has to be based on some historical guesswork. For example, historians know that skull cups, similar to the ones in the study, were previously found at burials of high-status Liangzhu citizens. As such, the discarded bones could have held some ritual or religious significance. However, researchers found that the bones in their study showed signs of poor health and nutrition, suggesting that they belonged to lower classes.Their hypothesis is that the discarded bones were seen as easily accessible raw material and that this was directly connected to the growth of an urban society. The bones possibly belonged to some kind of other, either lower-class people or foreigners, whose anonymity in a large urban society with weak social ties led to their bones being used for another purpose. In ancient Liangzhu, the coexistence of two distinct concepts of corpse treatment namely, burial and use as raw material for production was perhaps made possible by the rise of an urban society, where the dead increasingly included unrelated strangers who were not regarded as subjects of commemoration, the researchers wrote. This distinction may reflect new social realities of urban life in which the anonymous dead became more available and more utilitarian in character.After reading about the modified bones found at Neolithic sites in China, discover the astounding story of the terracotta warriors, the thousands of life-like sculptures made to guard an ancient Chinese emperor.
