The remains were first discovered in the 1940s in Dallas County, west of Selma , Alabama, and North Carolina , in the Black Creek Formation.
The holotype, which is in the collection of the Field Museum in Chicago , consists of fragmentary bones of the skull and an incomplete postcranial skeleton. The skull has a small pyramidal process between the eyes.
Body length about 15 meters, height about 5 meters, weight about 1 ton.
The genus is described by in 1960 [1] . The name Lophorhothon means "nose with a comb" (from the Greek. Lophos - "comb" and Greek. Rhothon - "nose"). The only species is Lophorhothon atopus [2] . The specific name comes from the Greek. atopos - “unusual” or “strange”.
The originally found skeleton was considered a young individual of representatives of the genus prozaurolof . In 1998, James Lamba suggested that the remains belong to the iguanodont [3] , but this theory has not received much recognition. In 2010, Prieto-Marquez and Norell published a cladogram, referring the loforoton to the hadrosaroid superfamily [4] .

Back in 2004, Horner, Weishampel, and Forster assigned Lophorhothon to hadrosaurins [5] . In 2012, this hypothesis was confirmed by a group of scientists led by Ramírez-Velasco [6] .
