The 2015 study established seven distinguishing traits of the genus as such. These were [[autapomorphies]], unique derived characters. On the back of the skull, the paroccipital process is curved in side view. The teeth have paired wear facets. The first neck vertebra, the [[Atlas (anatomy)|atlas]], has a [[neural spine]] with processes pointing to the front and the inside, which are separate from the rear wing of the spine. This rear wing shows a continuous transverse width over most of its length. The [[neural arch]] of the atlas has on each side of its base a small triangular spur. The second neck vertebra, the [[Axis (anatomy)|axis]], has a neural spine with a knob-shaped bump on the front end of the ridge on its front side. With the middle and rear neck vertebrae, the ridge between the rear joint processes, the [[postzygapophysis|postzygapophyses]], does not extend beyond the rear edge of the neural arch.<ref name=TMB2015/>
