The Sunghir 2 and 3 late juvenile to early adolescent immature skeletons, from the Mid Upper Paleolithic (Eastern Gravettian) of northern Russia, exhibit several episodes of dental enamel hypoplasias. Those of the older male Sunghir 2 relate principally to a stress episode in the third year post‐natal, although subsequent minor stress episodes may be indicated. They are not accompanied by other marked developmental abnormalities. The younger female Sunghir 3 exhibits at least three episodes of pronounced post‐natal stress through the third to fifth years post‐natal, followed by femoral and tibial growth arrest lines that formed shortly before her death at 9–11 years. These first decade post‐natal stress episodes of Sunghir 3 may be related to the same developmental condition that produced her abnormally bowed femora pre‐natally and/or to continued frailty related to that condition. Surviving these stress episodes for different lengths of time, both Sunghir 2 and 3 were awarded the most elaborate Paleolithic burial known. Copyright © 2011 John Wiley & Sons, Ltd.
