A. Prieto-Márquez and M. A. Norell 2010Hadrosauroid ornithopod characterized by the following autapomorphies and unique combination of characters: paddle-shaped postacetabular process that is less then 70% of the length of the iliac central plate; ilium combining the presence of ischial tuberosity and supraacetabular process with apex located posterodorsal to ischial peduncle; manual phalanx III-1 with greatly asymmetrical distal surface.
