Their fossils have long shown grim signs of cannibalism, mostly involving children. Archaeologists with the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) announced the discovery of 24 new H. antecessor fossils at the Gran Dolina site in Spain. In 2010, archaeologists, including project co-director Palmira Saladié, proposed that H. antecessor cannibalized their young. According to an explainer by the Australian Museum, it’s debatable whether this truly points to cannibalism, but archaeologists haven’t found evidence for alternative scenarios, such as H. antecessor funerary rites. In addition to the adult bones, the team also unearthed a trove of stone tools and animal remains from hyenas, beavers, horses, rhinos, and more.
