All the neural arches of the preserved vertebrae are fused to their respective centra, suggesting that the holotype of Equijubus normani, IVPP V 12534, is a skeletally mature individual (Brochu, 1996). There are only six vertebrae in the sacrum, a low number compared to other basal iguanodonts (see above), but the first and sixth preserved sacrals are incomplete; thus, the low sacral count might be due to incomplete preservation of the sacrum rather than lack of fusion between sacral vertebrae.
