Latirhinus

Latirhinus (meaning "broad nose" from the Latin latus (broad) and Greek ῥίς, rhis (nose)) is an extinct genus of lambeosaurine 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.

== Discovery and research == During the 1980s, a team from UNAM's Geological Institute, including Shelton P. Applegate, René Hernández-Rivera, Espinosa-Arrubarrena, the SEPC team, and some volunteers, excavated the remains of a dinosaur near the town of Presa de San Antonio, belonging to the Cerro del Pueblo Formation in the Parras Basin, located in Coahuila, Mexico. The specimen was found by Don Ramón López, which was a juvenile specimen of 6 meters long, 2.2 height at the waist, and an estimated weight of 3 tons, of which 65% was recovered. This was the first dinosaur skeleton from Mexico to be mounted for public display. This specimen, though fairly complete, lacked a skull, but was identified as the saurolophine Kritosaurus sp. based on comparisons with Kritosaurus incurvimanus, which is now considered a more recent synonym of Gryposaurus notabilis. Due to its importance, the skeleton was given the informal name of "Isauria", and it is exhibited in the Museum of the Institute of Geology of the UNAM, Universum, Museo Papalote in the State of Hidalgo, Museo del Desierto, and several private parks. Serrano-Brañas, in 2006, identified one of the bones collected as a supposed nasal, and together with the appendicular skeleton, he referred to the genus Gryposaurus in his thesis.
