Fig. 6. Cervical vertebrae of diplodocids exposing osteological correlates for soft−tissue. A. Cervical vertebra of Diplodocus (SMA L25−3), Howe Stephens Quarry, Wyoming, USA, Morrison Formation, Kimmeridgian, Late Jurassic, in left lateral aspect (A1) and as schematic drawing with insertion areas for tendinomuscular apparatus (A). B. 4th cervical vertebra (SMA D25−2) of undetermined juvenile diplodocid, Howe Stephens Quarry, Wyoming, USA, Morri2 son Formation, Kimmeridgian, Late Jurassic, in cranial (B1) and caudal (B2) aspects. C. Isolated neural spine of a cervical vertebra of Apatosaurus excelsus (CM 555), Quarry D (Sheep Creek), Wyoming, USA, Morrison Formation, Late Jurassic, in caudal aspect showing postspinal fossa. D. Cervical vertebra of Barosaurus lentus (CM 1198), Carnegie Museum Quarry at Dinosaur National Monument, Utah, USA, Morrison Formation, Late Jurassic, in caudal aspect showing postspinal fossa containing pneumatic foramina. E. Cervical vertebra of Diplodocus (SMA L25−3), Howe Stephens Quarry, Wyoming, USA, Morrison Formation, Kimmeridgian, Late Jurassic, in dorsolateral aspect showing large pneumatic foramen. F. Cervical vertebra of Diplodocus sp. (SMA, no collection number), Howe Stephens Quarry, Wyoming, USA, Morrison Formation, Kimmeridgian, Late Jurassic, in cranial aspect with close−up showing peduncle for interspinal elastic ligament (F1) and in caudal aspect (F2).
