Final answer:

True, an anteriorly placed foramen magnum is indicative of bipedality, as it aligns the skull over the spine for upright walking.

Step-by-step explanation:

A more anteriorly placed foramen magnum is indeed indicative of bipedality. This is because such a placement of the foramen magnum aligns the skull more directly atop the spine, which is a characteristic seen in bipedal organisms, allowing them to walk on two legs effectively. In contrast, quadrupedal animals typically have a foramen magnum located more posteriorly, which is better suited for their mode of locomotion.
