Monoclonius-life restoration

Monoclonius was a Cretaceous period ceratopsian. It had only one horn (on its nose). Unlike Styracosaurus, which had long frill-spikes, Monclonius had short frill-spikes. Only one appears in The Land Before Time, in Mr. Thicknose's flashback in The Land Before Time VIII: The Big Freeze.
