%X Objectives: This study aims to examine primate postcanine tooth root surface area<br>(TRSA) in the context of two ecological variables (diet and bite force). We also assess<br>scaling relationships within distinct taxonomic groups and across the order as a<br>whole.<br>Materials and Methods: Mandibular postcanine TRSA was measured using a three-<br>dimensional computed tomography (CT) method for catarrhine (N = 27), platyrrhine<br>(N = 21), and strepsirrhine (N = 24) taxa; this represents the first sample of<br>strepsirrhines. Two different body size proxies were used: cranial geometric mean<br>(GM) using nine linear measurements, and literature-derived body mass (BM).<br>Results: TRSA correlated strongly with body size, scaling with positive allometry or<br>isometry across the order as a whole; however, scaling differed significantly between<br>taxa for some teeth. Among Strepsirrhini, molar TRSA relative to GM differed signifi-<br>cantly between folivores and pliant-object feeders. Additionally, P4 TRSA relative to<br>BM differentiated folivores from both hard- and pliant-object feeders. Among<br>Cercopithecoidea, P4 TRSA adjusted by GM differed between hard- and pliant-object<br>feeders.<br>Discussion: Dietary signals in TRSA appear primarily driven by high frequency loading<br>experienced by folivores. Stronger and more frequent dietary signals were observed<br>within Strepsirrhini relative to Haplorhini. This may reflect the constraints of ortho-<br>gnathism within the latter, constraining the adaptability of their postcanine teeth.<br>Finally, because of the strong correlation between TRSA and BM for each tooth locus<br>(mean r2 = 0.82), TRSA can be used to predict BM in fossil primates using provided<br>equations
