Adelolophus ✝
Description | Adelolophus ("unknown crest") is a genus of lambeosaurine hadrosaurid dinosaur (a crested "duck-bill") from Upper Cretaceous rocks in the U.S. state of Utah. It is based on University of California Museum of Paleontology specimen 152028, a right maxilla (tooth-bearing bone of the upper jaw). This specimen was found in the Campanian-age Wahweap Formation within Grand Staircase-Escalante National Monument. Adelolophus was described by Terry Gates and colleagues in 2014. The type and only known species is A. hutchisoni. The generic name is derived from Greek δηλόω, "to reveal" and λόφη, "crest". The specific name is a reference to Dr. John Howard Hutchison, who found the specimen in 1999. The authors interpreted Adelolophus as the oldest known lambeosaurine from North America, at approximately 78 million years old. The specimen was first reported and shortly described in 2013.
