DiscoveryEdit

Gryphoceratops is known only from the holotype ROM 56635, a partial right dentary. The holotype was collected in the northwest corner of Dinosaur Provincial Park, from bonebed 55 of the Milk River Formation, dating to the late Santonian stage of the middle Late Cretaceous period, about 83.5 million years ago. Thus, Gryphoceratopsrepresents the oldest known leptoceratopsid. However, a cladistic analysis found it to be one of the most advanced leptoceratopsids. It is also probably represents the smallest adult-sized ceratopsian known from North America.^[1]

EtymologyEdit

Gryphoceratops was first named by Michael J. Ryan, David C. Evans, Philip J. Currie, Caleb M. Brown and Don Brinkman in 2012 and the type species is Gryphoceratops morrisoni. The genus name means "griffin horned face", as a reference to the beaked head, and the species name honors Ian Morrison, who prepared the holotype specimen.^[1]
