Some people say it was because of a volcano urrupting, some say the ice age. I would say ice age though because a volcano could not kill all the dinosaurs.

Type your answer here... there might be a new one were all the dinosures on the island become extinced
Because they stuck together. +++ No it wasn't. Some species may have been herd animals but I don't think there's any evidence for that. They were successful because conditions for them were reasonable stable for a very long time. Individual species came and went, of course.
