Fig. 7. Reconstruction of soft−tissues in the neck of Diplodocus. A. Transverse cross−sections through cervical vertebra with bifurcate neural spine in the diapophysis region (A1) and in caudal third of vertebra (A2). B. Transverse cross−sections through cervical vertebra with single neural spine in diapophysis region (B1) and in caudal third of vertebra (B2), dashed outlines representing possible craniocervical extensor muscle analogous to m. biventer cervicis of extant birds or m. transversospinalis capitis of extant crocodylians. C. Reconstruction of cervical ligaments in left lateral aspect. D. Reconstruction of cervical axial musculature in left lateral aspect. Vertebrae and skull for C and D from Diplodocus carnegii (Hatcher, 1901). Not to scale.
