Latirhinus (meaning "broad nose" from the Latin latus (broad) and Greek ῥίς, rhis (nose)) is an extinct genus of saurolophine hadrosaurid dinosaur from the Late Cretaceous of Mexico. The type species, Latirhinus uitstlani, was named in 2012 on the basis of a partial skeleton from the Campanian-age Cerro del Pueblo Formation. The specific name uitstlani means "southern" in the Náhuatl language of Mexico, a reference to the species' southern occurrence in the Cretaceous landmass Laramidia. Latirhinus is characterised by its large, arched nasal bones above the snout and larger narial or nostril openings. It is most similar to the saurolophine Gryposaurus.[1]
