Pachyrhinosaurus
和名：パキリノサウルス
世界共通発音：パッキーリノソーラス pak?ee?rhino?saw?rus
命名意味：Thick?nosed Lizard
分類所属：
Ornithischia / Genaria / Cerapoda / Marginocephalia / Ceratopsoidea
First Described 1950 / Found: North America: Canada
/ Length: 6m / Weight: 2t
Food: Plants / Young: Eggs
/ Lived: Late Cretaceous 70-66 million year ago
恐竜説明：
Twelve or more skulls and some disconnected bones have been found in the western states of Canada. The form of the body, therefore, has been built up by comparing the known remains with those of other horned and frilled dinosaurs. Instead of a nose horn, Pachyrhinosaurus had a large, bony bump on its nose. It was probably used for defence and during the fierce battles among the dominant males fighting to protect their territory and breeding partners. Head?butting and pushing would have been the chosen battlefield strategy.
Pachyrhinosaurus had a short frill at the back of its head similar to that of Triceratops.
During Late Cretaceous times, large herds of horned dinosaurs roamed the open lands of the western area of the North American continent. They were constantly on the lookout for Tyrannosaurus rex and, when spooked, were capable of running at speeds of more than 20 kph. Even the 'Tyrant Lizard' would get out of the way of a stampede of these formidable creatures.
