| The tubercula of the ribs articulate with the sides of the centra of the thoracic vertebrae, not with the transverse processes. |
| Nearly all of the vertebrae within this sequence are complete, with the centra and neural arches fused. |
| The cervical centra are amphicoelous, but do not have the deep, bowl-shaped concavity as in Polycotylus. |
| Video conferencing was identified as a way to bring together all the elements of the NZi3 centra and to foster links with external partners. |
| The neural arches are also noticeably thicker than in semijunctus, and the centra are rounded inferiorly rather than carinated. |
| The dorsal and ventral edges of the centra are more nearly equal in width in the larger specimens. |
