Fossil remains for this Dinosaur have been found in North America

Monoclonius was among the first North American dinosaurs discovered in the West. It was discovered in 1876 and it has only one horn, which was located just above its nose. Otherwise, it was similar to its other ceratopsian family members, particularly Centrosaurus  In fact, some scientists believe that it may be a Centrosaurus  and it might be renamed in the future.

Only one reasonably complete skull of Monoclonius has been found. Recent studies have noted that most species within this genus are based on very fragmentary or composite skeletal materials. One species is based solely on a nasal horn.
