Vertebral Morphology, Alternation of Neural Spine Height, and Structure in Permo-Carboniferous Tetrapods, and a Reappraisal of Primitive Modes of Terrestrial ... of California Publications in Zoology)

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.Sumida, Stuart S. is the author of 'Vertebral Morphology, Alternation of Neural Spine Height, and Structure in Permo-Carboniferous Tetrapods, and a Reappraisal of Primitive Modes of Terrestrial ... of California Publications in Zoology)', published 1990 under ISBN 9780520097551 and ISBN 0520097556.
