Linear EH in permanent teeth is a widely accepted marker of systemic physiological stress. An enigmatic, nonlinear form of EH commonly manifest in great ape and human deciduous canines (dc) is known as localized hypoplasia of primary canines (LHPC). The etiology of LHPC and what it signifies\u2014localized traumatic or systemic physiological stress\u2014remains unclear. This report presents frequency data on LHPC, hypostotic cranial traits, and tooth size in a sample of juvenile bonobos, then tests hypotheses of intertrait association that improve knowledge of the etiology and meaning of LHPC. The fenestration hypothesis is tested using hypostotic cranial traits as a proxy for membrane bone ossification, and the relationship between tooth size, LHPC, and hypostosis is investigated. Macroscopic observations of EH, hypostotic traits, and measurements of buccolingual tooth size were conducted according to established standards. LHPC was found in 51.2% of bonobos (<jats:italic>n<\/jats:italic> = 86) and in 26% of dc teeth (<jats:italic>n<\/jats:italic> = 269). Hypostotic traits were observed in 55.2% of bonobos (<jats:italic>n<\/jats:italic> = 96). A test of the association between LHPC and hypostosis yielded nonsignificant results (\u03c7<jats:sup>2<\/jats:sup> = 2.935; <jats:italic>P<\/jats:italic> = 0.0867). Primary canines were larger in specimens with LHPC than in unaffected specimens (paired samples <jats:italic>t<\/jats:italic> test; udc, <jats:italic>P<\/jats:italic> = 0.011; ldc, <jats:italic>P<\/jats:italic> = 0.018), a result consistent with the fenestration hypothesis of LHPC pathogenesis. Hypostosis was not associated with differences in tooth size (<jats:italic>P<\/jats:italic> &gt; 0.05). LHPC may be an indirect indicator of physiological stress, resulting from large, buccally displaced primary canines.
