Although known only from two fragmentary Moreno Formation specimens — "LACM/CIT 2852" and "LACM/CIT 2760" from Fresno and Benito counties respectively — Augustynolophus has attracted plenty of attention down the years. William Morris assigned its remains to Saurolophus sp. in 1973, then Phil Bell and David Evans argued that the holotype skull was no different to that of Edmontosaurus in 2010. Albert Prieto-Márquez and Jonathan Wagner went to great lengths to prove that Morris was right in the first place and named Saurolophus morrisi in his honor in 2011. Then they enlisted Bell and Luis Chiappe in 2014, fully prepared "LACM/CIT 2760", and coined Augustynolophus based mainly on a previously hidden snout bone that formed part of a head crest.
(Morris' Augustyn crest)EtymologyAugustynolophus is derived from "Augustyn" (for the Augustyn family who have been generous in their financial support of Californian palaeontological research for many years) and the Greek "lophos" (crest). The species epithet, morrisi, honors William Morris.
DiscoveryThe holotype remains of Augustynolophus (LACM/CIT 2852; a partial skull and skeleton) were discovered in the Marca Member of the Moreno Formation, in the Panoche-Tumey Hills of Fresno County, central California, USA, by Chester Stock in 1939.
Stock discovered a second specimen (LACM/CIT 2760) in the Moreno Formation of Benito County in 1940, which is around 30% smaller than the holotype.
