The entire structure has been remodeled to accommodate an upright stance and the need to balance the trunk on only one limb with each stride.
The talus, in her ankle, shows evidence for a convergent big toe, sacrificing manipulative abilities for efficiency in bipedal locomotion.
If it occurred after she died but while the bone was still fresh, then it may not be related to her death.
Back to top There are several indicators which give a fair idea of her age.
The shaft is angled relative to the condyles (knee joint surfaces), which allows bipeds to balance on one leg at a time during locomotion.
