We examine the effect of inaccurately located Fe and Ti midshafts on estimation of geometric properties. The error ranges were compared on 30 Fe and Ti. Cross-sections were obtained at each 1% interval from 60% to 40%, 5% of deviation from midshaft was used as the maximum acceptable error. Reliability was expressed by mean percentage differences, standard deviation of percentage differences, mean percentage absolute differences, limits of agreement, and mean accuracy range (MAR). On average, Ti CA and Fe I are the least sensitive to positioning error, with MAR wide enough for practical application in fragmentary specimens (MAR = 40--130 mm). In contrast, Ti I are the most sensitive to error in midshaft location (MAR = 14--20 mm). Individuals present significant variation in morphology and thus in error ranges for different properties. For damaged fossil Fe and Ti we recommend carrying out additional tests to better establish specific errors associated with uncertain length estimates.
