NEXUS file without list of character states from Supplemental Data "Within the Norman (2015) matrix we recoded character states for several taxa in character 63 (dentary teeth, primary ridge: absent (0), mesial/median position and prominent (1), distally offset and modestly developed (2)). In this case the taxa Parasaurolophus walkeri, E. regalis, and Saurolophus osborni were all coded as state 3 in the published matrix when no such state exists for that character as currently written; instead we changed the coding to state 1."
