Chasmosaurus

Chasmosaurus (name meaning "chasm lizard") is a genus of chasmosaurine ceratopsian dinosaur that lived in North America during the late Cretaceous period.

Last Killers
A Chasmosaurus is first seen being stalked by a Daspletosaurus as it forages. However, it detects the tyrannosaur and charges at it, forcing the Daspletosaurus to give up. Later, the Chasmosaurus leaves the forest and continues foraging when it spots a juvenile Daspletosaurus nearby. Remaining wary, the ceratopsian keeps an eye on it, but it soon finds itself being surrounded by the rest of the pack. It dashes off, attempting to escape, but the Daspletosaurus gives chase. After a while, the Chasmosaurus is brought down and killed by the tyrannosaurs, who then begin feasting on it.
