 In the cervicals of the neck, each leaf of the table is angled up at 45° and forms a roughly rectangular shape from above, while those of the dorsals are flatter and the table is more shield-shaped, with a straight front edge and pointed at the back.These 'Y'-shaped neural spines are only found in the cervicals and first four dorsals, behind them the neural spines are only slightly expanded at their tips and became more slender down the spine.Nine osteoderms are known, forming a single row running down the spine that split into two long pointed spines at the back with smooth, thin surfaces.
