This connective tissue sheet encloses the dorsal and lateral por- tions of the spinal canal and its contents. Ventrally, strong fibers of connective tis- sue bind each arch to the thick fibrous connective tissue between the anterior (first) vertebra and the exoccipital. Pos- teriorly, the border of the entire arch is joined by a sheet of connective tissue to the neural arch of the first vertebra. Suc- cessive neural arches are connected to each other in a similar manner. There are 87 (63) vertebrae. Mukhach- eva (1978) summarizes vertebral counts for Diplophos species. The first vertebra consists of an amphicoelous disc-shaped centrum associated with autogenous dor- solaterally-articulated neural arches and ventrally-articulated parapophyses. These structures are finnly bound by fibrous connective tissue to the relatively deep fossae which they fill. The neural arch of each side dorsally meets its counteri^art in the same manner as the accessory neural arch. The neural arches are anteroposteriorly broad along their dorsal border. The posterior border of the neu- ral arch is fused with a short neural spine which is unfused to the spine of the con- tralateral side. Well ventrally on the pos- terior area of the neural arch at the an- terior base of the ne
