"Magdalenian Girl" or "Magdalenian Woman" () is the common name for a human skeleton, dated to the boundary between the Upper Paleolithic and the early Mesolithic, ca. 15,000 to 13,000 years old, in the Magdalenian period. The remains were discovered in 1911 in the Dordogne region of southwestern France in a limestone cave known as the Cap Blanc rock shelter. The find was made when a workman drove a pickaxe into the cliff face in the rock shelter, shattering the skull. It is the most complete Upper Paleolithic skeleton in Northern Europe. When Magdalenian Girl was acquired in 1926 for the Field Museum in Chicago, Illinois by Henry Field, then curator of Physical Anthropology, it was hailed as one of the most significant acquisitions the museum ever made. On the first day the precious specimen was exhibited, tens of thousands of visitors flocked to the museum to see it. Skeletal analysis Sex There was some speculation as to her sex but it was ultimately decided by the size and shape of her pelvic bones, which is a major indicator of sex in skeletons. Age There is still some debate about the age of Magdalenian Girl. For years, the individual was thought to be a young girl, because her wisdom teeth had not yet advanced, but new analysis indicates that her wisdom teeth were impacted, and that she was actually 25 to 35 years old when she died. This is the oldest recorded case of impacted wisdom teeth. Other evidence that indicated her age were fully fused epiphyses and degenerative wear on her vertebrae. According to Dr. Robert D. Martin, primatologist and Field Museum provost, along with Dr. William Pestle, Field Museum Collection Manager, Drs. Michael Colvard and Richard Jurevic of the College of Dentistry at the University of Illinois at Chicago, Magdalenian Girl is most likely significantly older than 18–21 years. Teeth There has been much debate over Magdalenian Girl's age due to her impacted wisdom teeth. According to Science Daily, impaction during the Stone Age was unknown because of the coarse diet of the period. This diet would have required more chewing and higher bite forces which could result in more growth of the jawbone and thereby creating more room for wisdom teeth to erupt. According to Robert D. Martin, "Finding impacted wisdom teeth 15,000 years ago indicates that the human diet might have already changed, some would say
