However, a newer study compared incidence rates of skull lesions in "Triceratops" and "Centrosaurus" and showed that these were consistent with "Triceratops" using its horns in combat and the frill being adapted as a protective structure, while lower pathology rates in "Centrosaurus" may indicate visual rather than physical use of cranial ornamentation, or a form of combat focused on the body rather than the head; as "Centrosaurus" was more closely related to "Styracosaurus" and both genera had long nasal horns, the results for this genus would be more applicable for "Styracosaurus". The researchers also concluded that the damage found on the specimens in the study was often too localized to be caused by bone disease.
