Monoclonius crassus

Monoclonius crassus - Late Cretaceous Dinosaur

Oil painting

Monoclonius was a medium sized, early ceratopsian and an ornithischian dinosaur, the order of bird-hipped dinosaurs. It was first described in 1876.  The name Monoclonius means "thick single sprout" and refers to the single root of the teeth. Its intelligence was intermediate among the dinosaurs.
It was a herbivore, it probably ate palms, cycads and other plants. It could chew them well with its cheek teeth. Monoclonius was probably a herding dinosaur and it was quite a slow-moving animal.
This one-horned animal walked on all four short legs with hoofed toes. It had a bulky body and a short thick tail. Its head was huge, with a small frill on it, a single nose horn and two smaller horns over its eyes. Males may have had larger frills than females; the frill may have been used for mating purposes. Monoclonius held its head close to the ground. One nose horn pointed to upwards. It had a short snout ending in a parrot-like. Its tough, hook-like beak was toothless, but it had many cheek teeth.
