Monoclonius armatus is a species of ceratopsian dinosaur that may or may not have originally lived in Montana during the late Cretaceous and may have went extinct as an extinct species, Monoclonius crassus, but was brought back from extinction by SciiFii and introduced throughout the modern tropical, subtropical, and temperate forested regions of North America to help boost biodiversity. The genus' existence during the Cretaceous is most likely dubious, and if it is true that Monoclonius crassus did not exist, the genus Monoclonius may be restricted to the Holocene (in the Cenozoic era) instead of the Mesozoic era. Monoclonius armatus is a rather large animal, reaching 5–5.5 metres (16–18 feet) in length and 2–2.5 metric tons (2.2–2.8 short tons) in body mass. Monoclonius armatus is covered in large scales with projections rising from their center, which are a deep orange-brown in color with a lighter underbelly and, in the males, small, light blue patches on their frills. Like many of SciiFii's de-extincted ceratopsians, it is covered in a light layer of primitive feathering. Like other centrosaurines, Monoclonius armatus bares a single large horn over its nose. This horn curves forwards or backwards depending on the specimen. Skull ornamentation is reduced as animals ages. The frill is relatively short compared to the total skull length, and can grow to over half a meter (68.8 centimeters) long in the oldest and largest adults. Monoclonius armatus is fully herbivorous and feed primarily on fruits, leaves, pine needles, pine cones, nuts, flowers, and, unlike most ceratopsians, grasses. Monoclonius armatus is a social animal that lives in small herds of up to 12 individuals at a time. During the breeding season, Monoclonius armatus males challenge other males to win a right to lead the herds and mate with the females. Monoclonius armatus breeds in a manner like most other ceratopsians. The conservation status of Monoclonius armatus is Least Concern due to successful conservation efforts and the species' wide range. Unlike many of the other large ceratopsians, Monoclonius armatus is easily domesticated and can be trained to eat weeding plants and invasive plant species, similarly to goats.
