Marrow is a valuable source of energy, fat, and nutrients that has been exploited by prehistoric and historic peoples across many different environments. Previous experiments on marrow yields have provided new insights into the nutritional value of many ungulates that were important to the diets of past hominins. However, few studies have been conducted on suids. To investigate the caloric value of suid marrow, we broke ten humeri, seven radii, eight femora and seven tibiae of domestic pig and two of each of these elements of wild boar (both Sus scrofa) limb bones using the hammerstone and anvil technique. The marrow inside was removed and dried so that its kilocaloric value could be calculated. In this paper we compare and discuss the kilocaloric yields of males and females, different elements, and different age groups and conclude that, beyond seasonality, body size and age are potential indicators of marrow kilocaloric yields. Further, we compare our data to available data on impala (Aepyceros melampus) and wildebeest (Connochaetes taurinus), and we conclude that these ungulates provided more marrow than suids, and therefore they may have provided more benefits as a food resource.
