Comment

Monoclonius (meaning "single sprout") is a dubious genus of herbivorous ceratopsian dinosaur found in the Late Cretaceous layers of the Judith River Formation in Montana, northern US, and the uppermost rock layers of the Dinosaur Park Formation in Alberta, Canada dated to between 75 and 74.6 million years ago.

Interesting fact

The 20 Riels - Norodom Sihanouk (Monoclonius) 1995 coin from Cambodia is unique because it features a portrait of King Norodom Sihanouk on one side and the Monoclonius, a prehistoric rhino-like mammal, on the other. This coin is a rare and interesting combination of history and natural history.
