Abstract

Blasisaurus canudoi gen. et sp. nov. is described on the basis of disarticulated skull and lower jaw remains found in the Blasi 1 locality of Ar?en (Huesca, south-central Pyrenees of Spain), located in the upper part of the Ar?en Formation, late Maastrichtian in age. This new lambeosaurine hadrosaurid is characterized by a jugal combining a hook-like dorsal edge of the posterior process and a narrow, D-shaped infratemporal fenestra. Blasisaurus differes from Arenysaurus from the Blasi 3 site of Ar?en mainly by the absence of secondary ridges in the dentary teeth, and from Koutalisaurus (probably a junior synonym of Pararhabdodon) from the Isona region of Lleida by the anteriormost portion of the dentary that is modestly deflected ventrally. A phylogenetic analysis places Blasisaurus as closely related to Arenysaurus in a clade of basla lambeosaurines more derived than Tsintaosaurus and Jaxartosaurus; this clade forms part of a polytomy with Amurosaurus and with more derived lambeosaurines. Palaeobiogeographically, the presence of Blasisaurus and other hadrosaurids in the Maastrichtian European archipelago suggests one or, more probably, a series of dispersal events from Asia across intermittent land bridges during the second half of the Late Cretaceous.
