aOnly a referred femur of Argentinosaurus is known: estimating its humeral circumference from the least-squares regression relationship between humeral and femoral circumferences for large sauropods (femoral circumferences >400 mm) yields a mass estimate of 67,400–124,000 kg (95% prediction interval).
