Triclonius

One of many large ceratopsian-like creatures that dwell on Skull Island the Triclonius is one of the few dinosaurs that were unique to the Island not unlike the Eotriceratops or the more known Ferrucutus. The Triclonius was just as if not even more violent then most of the predatory beast that try to hunt it even the most hungry of Vastatosaurs wouldn't dare risk getting impaled by the beast's large horn.
