 However, because no postcranial remains (i.e., bones below the skull) have been discovered, it is not known definitively whether "Sahelanthropus" was indeed bipedal, although claims for an anteriorly placed foramen magnum suggests that this may have been the case.Upon examination of the foramen magnum in the primary study, the lead author speculated that a bipedal gait "would not be unreasonable" based on basicranial morphology similar to more recent hominins.Some palaeontologists have disputed this interpretation, stating that the basicranium, as well as dentition and facial features, do not represent adaptations unique to the hominin clade, nor indicative of bipedalism; and stating that canine wear is similar to other Miocene apes.
