Blasisaurus canudoi gen. et sp. nov., a new lambeosaurine 
dinosaur (Hadrosauridae) from the Latest Cretaceous of 
Arén (Huesca, Spain).

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 Arén (Huesca, south-central 
Pyrenees of Spain), located in the upper part of the Arén 
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 differs from Arenysaurus from the Blasi 3 
site of Arén 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 basal 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.
