Interestingly, the transition sequence of nasal horn evolution is partially recapitulated in the ontogeny of Pachyrhinosaurus and presumably other pachyrostrans, in which the nasal horn is first developed as a simple undulating ridge, which transforms into a relatively taller, yet broad-based horn-like structure that is subsequently remodeled into a low, rugose nasal boss [33 ].
