Cut marks suggestive of cannibalism have been discovered on the fossils of an ancient human relative in a cave in Spain, new research finds. But many of the bones from the species, known as Homo antecessor, were from adults ‪—‬ not just children, as previous discoveries had found ‪— adding a new dimension to the cannibalism that was practiced in this area 850,000 years ago.

The two dozen bones and teeth were recently found in Gran Dolina cave, part of the Sierra de Atapuerca archaeological complex in northern Spain, according to a July 24 translated statement from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES). Among the remains were fragments of a skull, spine, arm and leg bones, as well as three teeth from several members of the now-extinct H. antecessor, a relative of modern humans that lived in Europe between about 1.2 million and 770,000 years ago. Several of the bone fragments had cut marks from stone tools.

Over the past few decades, researchers have identified numerous cases of cannibalism at Gran Dolina, meaning H. antecessor is the oldest known human relative to eat its own group members for nutritional reasons. In a 2010 study, researchers noted that most of the evidence of cannibalism at Gran Dolina came from the bones of infants and juveniles, who would have been easier to capture and kill as the young, defenseless members of a rival group. But the newly excavated fossils have upended that assumption.

"The discovery of more adult individuals, some of whom also bear cut marks, demonstrates that cannibalism was not restricted to younger individuals," Palmira Saladié, a biological anthropologist at the IPHES who coordinated the work, said in the statement.

The number of individuals found at Gran Dolina has now risen to at least 13, and about half of them are adults. "The increase in the number of individuals, and especially the addition of more adults, allows us to begin understanding this population from a much more complete perspective than ever before," Andreu Ollé, an archaeologist at the IPHES, said in the statement.

Excavation at Gran Dolina has also brought to light an assemblage of stone tools made from flint, quartzite and sandstone, along with animal bones from hyenas, beavers, deer, horses and rhinoceroses, according to the statement.

Evidence of cannibalism at the site is extensive. Stone tools found in the cave are consistent with the cut marks on the human bones, and the animal bones have revealed butchering techniques that were also used on humans. Some of the human bones also had human bite marks, Saladié told Live Science in 2025, which is the "most reliable evidence that the bodies found at the site were indeed consumed."

But while the practice of cannibalism at Gran Dolina has been confirmed, the reason for it is still unclear. Researchers hope the newly discovered adult bones may help them better understand the practice among H. antecessor groups.

"We have only just begun excavating this new area" at Gran Dolina, Marina Mosquera, an archaeologist at the IPHES, said in the statement, "and the first results already demonstrate its enormous scientific potential."

Further analyses on the bones are now underway to explore questions about age-related differences in cannibalism, the number and length of cannibalistic episodes, and the social organization of H. antecessor, according to the statement.

The ancient Egyptians sometimes reused crafted materials. This block, which features a battle scene, was likely created during the reign of Amenhotep II between 1427 and 1400 B.C., during the 18th dynasty. But when it was discovered, the block was being used as part of the foundation of the unfinished mortuary temple of Ramesses IV (who ruled from 1153 to 1147 B.C., during the 20th dynasty).

The painted sandstone slab was discovered in Luxor in 1912 by Egyptologist Herbert E. Winlock, who later became the director of the Metropolitan Museum of Art, which has the block in its collection. In his original publication describing the artifact, Winlock wrote that it featured a scene of an Egyptian pharaoh slaying his enemies with a bow and arrow. "The block may be taken as one of the best preserved specimens of the great imperial pictorial-relief yet discovered," he wrote.

The excellent preservation of the artifact and its vibrant colors was likely due to its reuse in Ramesses IV's temple foundations, Catharine Roehrig, the Met's curator emerita of Egyptian art, wrote in a 2008 explanation of the relief fragment.

Measuring roughly 24 by 45 inches (61 by 115 centimeters), the painted sandstone carving was likely part of a larger scene depicting an Egyptian pharaoh vanquishing an enemy army, according to Roehrig. The pharaoh's chariot and horses appear in the upper-right corner, while a rival soldier tries to avoid being trampled to death. Three of the enemies have been pierced by arrows.

The pointed beards and distinctive clothing suggest the enemies were ancient Syrians or possibly the Hyksos, a Semitic-speaking foreign dynasty that ruled Egypt from around 1640 to 1530 B.C., during the Second Intermediate Period, James P. Allen, former curator of Egyptian art at the Met, wrote in 2005. The battle scene may therefore reflect historical conflicts fought between dynasty 18 pharaohs like Amenhotep II and Asiatic rulers.

But the relief was unlikely to have been created as a commemoration of a specific historical battle. "Their primary purpose was to portray the pharaoh in his role as the victorious defender of Egypt," Roehrig wrote.
