Question marks indicate measurements that cannot be made due to breakage and/or poor preservation.
*Measured parallel to the long axis of the spine from the dorsal surface of the transverse processes.
†Minimum measurement due to breakage.
‡Measurement biased by crushing.
§Measurement reconstructed due to breakage.
