The average diameter of the posterior face of the centrum is 165 millimetres (6.5 inches), with a concave surface. This concavity is deep enough to suggest that the anterior faces of vertebrae from this part of the dinosaur's spine would have been convex to articulate with such a shape.<sup id="cite_ref-TN07_2-0" class="reference"><a href="#cite_note-TN07-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>The specimen displays several <a href="/wiki/Apomorphy" class="mw-redirect" title="Apomorphy">distinguishing characteristics</a>.
