Summary

Description
English: Skeletal reconstruction of the unaysaurid sauropodomorph Macrocollum (CAPPA/UFSM 0001b) showing vertebral elements along the spine and putative reconstruction of the air sac systems involved. (a) Pneumatic posterior cervical vertebra and a cross-section CT slice in b. (c) a pneumatized anterior dorsal vertebra with cross-section CT slice in d, and detail of the pneumatic foramen in e. (f) Detail of the pneumatic foramen in a reconstructed 3D model of the element. (g) Anterior cervical element (apneumatic). (h) Posterior dorsal vertebra shows no traces of PSP. The sacral series (i), as well as the anterior (k) and mid-caudal (j) series are apneumatic. a, g, h, j, and k are in left lateral view. c, e and f are in right lateral view. i is in dorsal view. ABD, abdominal diverticula; CER, cervical diverticula; LUN, lung; pf, pneumatic foramen. The reconstruction was made by Rodrigo T. Müller. Scale bar of the skeletal reconstruction = 500 mm; a–j = 20 mm.
