From Christiansen and Harris (2005) and Campione and Evans (2012) we can show a comparison.

Campione and Evans (2012) report a bear humerus 400.5 mm long and 146.25 mm in circumference (robusticity index 0.365). The closest in length humerus reported by Christiansen and Harris (2005) is 387.5 mm long and 155 mm in circumference (robusticity index 0.4). So from this small sample size, Smilodon populator is more robust in the humerus. In the femur, the bear femur was 445.5 mm long and 126.25 mm in circumference (index 0.28). The longest S. populator femur in Christiansen and Harris (2005) was 390.4 mm long and 113.5 mm in circumference (index 0.29). S. populator was front heavy while bears are more balanced so that skews the comparison somewhat. Nonetheless it appears S. populator bone-wise is more robust. Reply
