However, the fossils from this genus have been sparse: only jaw and tooth fragments have been found so far.

Kulceratops belonged to the Ceratopsia (the name is Greek for "horned face"), a group of herbivorous dinosaurs with parrot-like beaks which thrived in North America and Asia during the Cretaceous Period.

As Kulceratops is the oldest known neoceratopian, Nesov assigned it to a special Archaeoceratopsidae.

Due to the paucity of the remains, it is considered a nomen dubium[citation needed] Kulceratops, like all ceratopsians, was a herbivore.

During the early Cretaceous, flowering plants were "geographically limited on the landscape", and so it is likely that this dinosaur fed on the predominant plants of the era: ferns, cycads and conifers.
