Archaeologists have found ancient infant bones, which may be the first physical evidence of an assisted birth in the Neolithic Dolomites. The remains of a full-term infant show a rare arm fracture that researchers believe occurred during a difficult delivery about 6,000 years ago.
The discovery came from the Ripari Alti rock shelters in northeastern Italy. The shelters sit about 3,600 feet above sea level in the Lamen Valley, near the city of Feltre.
A research team led by Omar Larentis examined the infant’s fragile bones using photography, digital microscopy and scanning electron microscopy. Radiocarbon dating placed the remains between 3932 and 3653 B.C., during the Late Neolithic period.
Researchers said the fracture most likely resulted from an attempt to pull or rotate the infant during an obstructed birth. The injury provides rare evidence that prehistoric communities may have used hands-on methods to help women facing dangerous complications during labor.
Infant remains reveal a rare discovery
Archaeologists recovered seven bone fragments representing six parts of the skeleton. They included the lower jaw, an upper arm bone, a forearm bone, a rib, and both shin bones.
The bones were scattered across a small area rather than found in their original positions. However, researchers concluded that they belonged to one individual. The left and right shin bones matched, no bones were duplicated, and all the remains showed the same stage of development.
Measurements indicated that the infant had reached about 40 weeks of gestation. This means the child was full-term or had been born shortly before death.
Fracture points to a difficult birth
The most important evidence came from the right upper arm. The humerus had broken along an angled, spiral-shaped line.

Under high magnification, the break showed smooth and curved surfaces. Researchers also found tiny flakes of bone and patterns associated with flexible, collagen-rich tissue. These features indicate that the bone broke while it was still fresh, either shortly before death or around the time of death.
The fracture looked very different from a break found on one of the ribs. That damage had the rough, straight features of a bone that broke after it had dried.
Researchers compare the injury with modern childbirth
Spiral fractures are caused by twisting forces rather than a direct blow. In newborns, such injuries are rare even in modern hospitals.
Clinical studies have linked them to difficult deliveries involving an abnormal fetal position, obstructed labor or shoulder dystocia. Shoulder dystocia occurs when a baby’s shoulder becomes trapped behind the mother’s pelvic bone.
During such emergencies, a person assisting the birth may need to pull or rotate the baby to free it. These actions can save lives, but they can also cause fractures.
Researchers said the infant’s arm may have been trapped while the body was turned or pulled. That movement could have placed enough pressure on the flexible bone to produce the spiral break.
The evidence cannot reveal exactly what happened. Researchers could not determine whether the infant was stillborn, died during delivery or survived briefly afterward. They also could not completely rule out an injury that occurred shortly after death.
However, the child’s age, the fracture’s location and its twisting pattern make a birth-related injury the most likely explanation, according to the study.
Bones also suggest maternal nutritional stress
The bones also showed signs of poor health before birth. Researchers found unusual porosity and thin, lace-like surfaces on the shin bones, forearm and jaw.
These changes may point to a lack of essential nutrients. Possible causes include deficiencies involving vitamin C, vitamin D or other nutrients needed for bone growth and collagen production.
Because the child had not yet begun eating independently, researchers said the condition would likely reflect the mother’s health during pregnancy. Nutritional problems may have affected both mother and fetus.
Neolithic communities in the region relied on farming, livestock, and gathered wild foods. Seasonal travel into the mountains may have limited access to fresh plants and other sources of important nutrients, particularly during winter.
Discovery offers a glimpse into prehistoric childbirth
The rock shelters may have served as temporary stopping points for groups moving between valleys and higher grazing areas. The presence of a pregnant woman or newborn suggests that families, rather than only individual herders, took part in those journeys.
Researchers said the fractured arm points to an active effort to manage a life-threatening birth. Although the intervention appears to have failed, it suggests that people in Neolithic communities shared practical knowledge about childbirth and tried to protect mothers and infants during emergencies.
The finding offers a rare view of reproductive care in prehistoric Europe. It also shows how a small injury preserved in fragile bones can reveal an intimate moment of danger, assistance, and survival thousands of years ago.
