Arenysaurus ardevoli is a lambeosaurine hadrosaurid from the late
Maastrichtian of Arén (Huesca, northern Spain) that has recently been
described. The holotype is the first and the most complete
lambeosaurine with a braincase from Europe. In this paper, we present
a complete description of the postcranial skeleton, which was poorly
described when the taxon was named because it was partially
unprepared, and new information on several cranial bones (jugal,
maxilla, and dentition). A new phylogenetic analysis of Arenysaurus
and the closely related Blasisaurus canudoi, also from the late
Maastrichtian of Arén, places them inside the Parasaurolophini in a
dichotomy with Parasaurolophus spp. Paleobiogeographically, the
presence of Arenysaurus and its relationships with other
lambeosaurines suggest at least one geodispersal event from Asia to
Europe no later than the middle–late Campanian.
