Foramen Magnum

Large opening in the occipital bone through which the spinal cord passes. The foramen magnum becomes more centrally located under the skull owing to the need to balance the head as a result of bipedalism; thus, any fossil hominoid with such an arrangement is believed to be bipedal and a hominid.
