Fig. 5. Cervical vertebrae of extant crocodylians and birds exposing osteological correlates for soft−tissue. A. Neural spine of 7th cervical vertebra of Crocodylus porosus (FUB OS 13) in cranial (A1), caudal (A2) and lateral (A3) aspects. Note subdivision of the rugosity for the interlaminar elastic ligament in A1 and A2. B. Neural spines of cervical vertebrae of Casuarius casuarius (NHM 1829) in craniodorsal (B1) and caudal (B2) aspects. Note bifurcate neural spine and distinct rugosity for the interlaminar elastic ligament in B. C. Neural spine of 14th cervical vertebra of Rhea americana (NHM 3534) in caudal 2 (C1) and dorsal (C2) aspect, with rugosity for interspinal elastic ligament virtually not being distinguishable from rugosity for interlaminar elastic ligaments, as in B and D. D. Neural spines of Sarcorhamphus gryphus (NMB 3295) in craniolateral (D1) and caudal (D2) aspect. Scale bars 10 mm.
