... 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...

—Outcrop panorama photograph of the upper sandstones of the Maestrichtian Aren Formation (northern Spain). The three sandstone units identified are characterized by stratal geometries similar to those observed at Joarcam. We interpret the uppermost sandstone unit on the right side of the photograph as a lowstand shoreline. See text for discussion. The middle sandstone unit shales out to the right across a relatively short distance at approximately the same location (Mutti and Sgavetti, 1987; Mutti et al., 1988).
