Abstract The structural characteristics of the supraorbital ridge in three extent primate species and fossil Neanderthals are described in this study. Surface morphology and patterns of trabecular organization as observed in cross‐sectional collections of Papio, Macaca and Pan are compared with similar traits encountered in the Pech de l'Aze infant, Gibraltar child, and La Quina 5, La Chapelle‐aux‐Saints, Broken Hill, Skhul V, Skhul IX, Tabun I and Gibraltar adult Neanderthals. Periods of rapid appositional growth of the browridges by means of fine cancellous bone formation and its subsequent remodeling and consolidation are temporally correlated with dental development and eruption sequences.
