What specific structure did the nasal bone fragment suggest Xenoceratops supported?
Answer
A substantial nasal horn or a heavily textured boss
Examination of the nasal bone fragment provides clues about the structure atop the snout of *Xenoceratops*. This evidence suggests the presence of either a substantial nasal horn or, alternatively, a heavily textured boss. Furthermore, this potential structure is noted as being similar in form to the structure observed in *Medusaceratops*. This feature, combined with the large brow horns situated over the eyes, contributed to its distinctive, though incompletely known, facial anatomy.
