Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. Cruzado-Caballero et al. 2010 | Lambeosaurine hadrosaurid characterized by a jugal with an autapomorphy resulting from the combination of a hooklike dorsal posterior process and a relatively narrow and D-shaped infratemporal fenestra. Also, it has a jugal with the following unique combination of characters: (1) posterior edge of the anterior process well-projected ventrally in a straight line (as in Parasaurolophus); (2) concave posteroventral edge beneath the infratemporal fenestra (as in Sahaliyania and hadrosaurines), and (3) very short jugal: length/height ratio lower than 1.2 (only Olorotitan (Godefroit et al. 2003), Velafrons (Gates et al. 2007), and Tsintaosaurus (IVPP V830; Young 1958, fig. 41; cf. T. spinorhinus in Prieto-Márquez 2008) have such a low ratio, in these genera due to the height of the postorbital process). | |
| A. Prieto-Marquez et al. 2013 | Lambeosaurine hadrosaurid characterized by the following autapomorphies: hook-shaped quadratojugal flange of jugal due to relatively elongated rostrally recurved dorsal process; and strongly asymmetrical, caudally skewed lateral contour of ventral flange of the jugal, so that rostroventral margin of flange is twice as long as its caudoventral border. Furthermore, Blasisaurus canudoi can be distinguished from other lambeosaurines by possessing the following unique combination of three jugal characters: orbital margin being wider than infratemporal margin, concave caudoventral margin of the ventral flange, and length/ height ratio of jugal less than 1.2 (diagnosis modified from Cruzado-Caballero et al., 2010a). |
