''Regaliceratops'' is a genus of herbivorous ceratopsid dinosaur that lived during the late Cretaceous period, about 68 million years ago (Mya) in what is now Canada. Closely related to ''Triceratops'', ''Regaliceratops'' was named for its plated frill, which its describers thought looked somewhat like a crown. In 2005, geologist Peter Hews discovered a skull at the Oldman River in Alberta. The fossil was secured by a team of the Royal Tyrrell Museum. The specimen was given the nickname "Hellboy" for its horns and the difficulty of removing it from the matrix. In 2015, Caleb Marshall Brown and Donald Henderson named and described the type species ''Regaliceratops peterhewsi''. The generic name combines Latin ''regalis'', "royal", a reference to both the crown-shaped neck shield and the "Royal" Tyrrell, with a Greek ''keras'', "horn", and ''ops'', "face". The specific name honours Hews.〔 The holotype, TMP 2005.055.0001, was found in a layer of the St. Mary River Formation dating from the middle Maastrichtian, about 68 million years old. It consists of a rather complete skull of which the snout bone, the rostral, is lacking. The skull has been deformed by compression and its rear and underside are obscured by matrix.〔 ''Regaliceratops'' was about five metres long, with an estimated weight of 1.5 tonnes.〔Will Dunham, 2015, "Meet 'Hellboy,' the dinosaur with exotic horns and frill", Reuters 04 June 2015〕 == See also == *Timeline of ceratopsian research 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Regaliceratops」の詳細全文を読む スポンサード リンク
