Fig. 4 in Pneumaticity and soft-tissue reconstructions in the neck of diplodocid and dicraeosaurid sauropods

Fig. 4. Reconstruction of the distribution of pneumatic diverticula in diplodocids and dicraeosaurids. A. Schematic drawing of midcervical vertebra of Diplodocus in left lateral aspect (A1), in dorsal aspect with single neural spine (A2) and in dorsal aspect with bifurcate neural spine (A3). The partitioning of pneumatic diverticula at the lateral surface of the vertebral corpus is hypothetical, based on the strongly divided pneumatic fossae. B. 10th cervical vertebra of Amargasaurus cazaui in left lateral aspect. C. 8th cervical vertebra of Dicraeosaurus hansemanni in dorsal (C) and in left lateral (C) aspects. Not to 1 2 scale.
