The holotype, specimen CIC/P/147, was first discovered as a semi-articulated tail in 2005 in sediments of the Cerro del Pueblo Formation in Coahuila, Mexico. In 2013, the Mexican National Institute of Anthropology and History and the National Autonomous University of Mexico launched a joint project to recover it. The holotype represents most complete lambeosaurine known from Mexico with an almost complete skull, jaws, and additional parts of the postcranial skeleton including an articulated tail.
