Dorso-ventral range of motion values at the cervical-dorsal boundary for Spinophorosaurus nigerensis, Plateosaurus engledhardti, Okapia johnstoni and Giraffa camelopardalis, measured as degrees between maximum dorsiflexion and ventriflexion in the referred vertebra.
| DV 3 | DV 2 | DV 1 | LCV | PCV | |
|---|---|---|---|---|---|
| Okapia | 3 | 4 | 3 | 9 | 17.5 |
| Giraffa | 5 | 4 | 14 | 25–27 | 25–28 |
| Plateosaurus | 4 | 4 | 8 | 10 | 10 |
| Spinophorosaurus | *7 | *9 | 17 | 27 | 28 |
DV = Dorsal Vertebra; LCV = Last Cervical Vertebra; PCV = Penultimate Cervical Vertebra. *Asterisk indicates estimated measurements based on field pose (dorsiflexion) and osteological stop of ribs (ventriflexion). Data from Okapia and Giraffa from Gunji & Endo26. Data from Plateosaurus from Mallison52.
