Figure 2. Comparison between the last sacral vertebrae of Baurutitan (MCT 1719-R) and Trigonosaurus (MCT 1488-R). A, last sacral vertebra (concave posterior facet), first biconvex, and anterior caudal vertebrae (Ca2 and Ca3) of Baurutitan. The red arrow indicates the opposite (biconvex) direction of the condyles in the vertebral centrum of the first caudal vertebra of Baurutitan. B, biconvex sacrum of Trigonosaurus. The thick red arrows indicate the first opisthocoelous sacral vertebra and the last procoelous sacral vertebra (convex posterior facet). C, E, articulation between MCT 1719-R and the sacrum MCT 1488-R. Red arrows highlight the direction of the neural spines in the last sacral and the first anterior caudal vertebrae. D, F, articulation between the caudal vertebrae of Baurutitan (MCT 1490-R; brown) and the sacrum MCT 1488-R. In E, the arrow indicates the more robust and posteriorly deflected feature of the transverse process of the anterior caudal vertebrae of MCT 1719-R, similar to the last sacral vertebra of MCT 1488-R.
