Which bone length is typically most informative when preservation is incomplete, and why?

• A. The radius, due to ease of preservation
• B. The tibia, due to density
• C. The femur, due to its large size and robust measurement properties
• D. The skull, because it preserves well

Answer: (C)

Estimating stature from skeletal remains relies on long bone lengths because they scale most reliably with overall height. When preservation is incomplete, you want the measurement with the strongest, least variable relationship to living height and with landmarks that remain clear and easy to measure. The femur fits this best: it is the longest bone, so its length captures most of the body's linear dimension, and its measurement is robust even when the specimen isn’t perfectly preserved. Regression models using femur length tend to produce the smallest height estimation errors, giving the most precise and reliable result when other bones are missing or degraded. The skull, while often well-preserved, does not correlate as strongly with height; the radius is shorter and more prone to measurement error, and the tibia, though informative, typically yields slightly less predictive precision than the femur. So, the femur provides the most informative height estimate under incomplete preservation.
