In this volume the author examines the pervasive pattern of alternation of structure and height of vertebral neural spines in the context of a larger review of axial structure in the most terrestrial of primitive Permo-Carboniferous tetrapods. He concludes that a coupled pattern of axial dorsiflexion and rotation played a significant role in primitive terrestrial locomotion.
