Teresa Maryańska and Halszka Osmólska based this genus on ZPAL MgD-1/110, a partial skeleton consisting of nine back vertebrae, nine hip vertebrae, fifteen tail vertebrae, a left ilium, parts of the left and right pubis, several ribs, and a few fragments of the hind limbs, with the backbone largely articulated. The most distinctive features of this skeleton are found in the neural spines. These are very tall, particularly over the hips, and were described as second only to those of Hypacrosaurus altispinus and the tips of those found in the first few vertebrae of the tail are club-shaped[1] (possibly a sign of old age).
