Zkameněliny tohoto dinosaura formálně popsal paleontolog Joseph Leidy v roce 1856.[2] O rok dříve fosilie objevil geolog Ferdinand Vandiveer Hayden v sedimentech souvrstní Judith River na území dnešní Montany. Tento taxon má nicméně složitou historii a v současnosti je považován za nomen dubium (pochybné vědecké jméno).[3][4]
