The bony labyrinth of the Sungir individuals was studied using the computed tomography scanning on an industrial Phoenix X-ray device. Three-dimensional modeling and visualization were carried out with special software. Crania of an adult (Sungir 1) and two children (Sungir 2 and 3) were analyzed. Findings reveal that bilateral asymmetry is insignificant. Individual variation range suggests that the group is morphologically homogeneous. Comparison of averages with those of Neanderthals and anatomically modern humans demonstrates overall similarity with the latter and significant difference from the former in key traits. Based on results of the discriminant analysis, children unambiguously fall in the H. sapiens group, while the adult is halfway between the latter and the Neanderthal sample. But such a finding is neither exceptional nor even rare. A Neanderthal-like morphology of the bony labyrinth (large lateral semicircular canal and high sagittal index) occurs in a small number of Upper Paleolithic humans of the modern morphological type. The Sungir adult belongs to this group.
