<i>Probrachylophosaurus bergei</i> gen. et sp. nov. skull reconstruction.

<p>(A) Preserved skull elements of MOR 2919, left lateral view. Predentary not included due to its poor preservation and diagenetic compression. (B) Outline of skull reconstruction, left lateral view. The outline accounts for diagenetic distortion of the posterior braincase, but otherwise does not correct for distortion of skull elements. Outlined regions where left skull material was not preserved are based on right bones when available. Regions with neither left nor right material preserved are hypothesized reconstructions based on <i>Brachylophosaurus canadensis</i> skulls. (C) Braincase with left nasal crest, dorsal view. (D) Outline of braincase reconstruction with nasal crest, dorsal view. Reconstruction accounts for diagenetic lateral compression and distortion of posterior braincase. <i>Abbreviations</i>: <i>d</i>, dentary; <i>ex</i>, exoccipital; <i>f</i>, frontal; <i>j</i>, jugal; <i>l</i>, lacrimal; <i>m</i>, maxilla; <i>n</i>, nasal; <i>p</i>, parietal; <i>pd</i>, predentary; <i>pf</i>, prefrontal; <i>pm</i>, premaxilla; <i>po</i>, postorbital; <i>q</i>, quadrate; <i>qj</i>, quadratojugal; <i>sa</i>, surangular; <i>sq</i>, squamosal.
