The initial collection was of 22 tail vertebrae, including a series of 16 consecutive bones, and other fragmentary hindlimb pieces.
By 2012, prepared material comprised 40 vertebrae, five partial thoracic ribs, part of the sacrum, fragments of the ilia, an ischium, the left and right pubic bones, and much of the right hind limb (femur, tibia, fibula, astragalus, and pes).
