Plesiosaur vertebrae: Appendix Tables

APPENDIX TABLE 1.

All measurements of CW, CH and CL are in mm. Incomplete measurements are represented by x. VLI and BI are ratios.

(WoD: width of diapophyses; Ns Ht: neural spine height; Nc Ht: neural canal height; Nc W: neural canal width; Angle: angle with centre of centrum; Dbfs: distance between foramina subcentralia; CV: cervicals; DV: dorsals; C: caudals).

APPENDIX TABLE 2.

Queensland Museum Collections sample numbering for the associated vertebrae of specimen QM F11050 (Eromangasaurus australis).

APPENDIX TABLE 3.
