  1. Number of joints evaluated: 740 cervical joints (37 atlanto-occipital + 259 intervertebral + 444 articular process joints) + 2407 thoracic joints (579 intervertebral + 1158 articular process + 670 [302 separate + 368 merged] rib joints) + 654 lumbar joints (218 intervertebral + 436 articular process joints) = 3801 joints
  2. *Pigs that received medical treatments are labelled with an asterisk; all available details are summarised in Supplemental Table 1
  3. aIn pig 8, T13 and T14 were fused to a block vertebra but were counted as two vertebrae because there were two primary ossification centres in the body of the block vertebra
  4. bVertebral wedging may have interfered with correct identification of the anticlinal vertebra in pig 21
