You are forgetting one of the most common defense systems in Nature: the
Buddy System (as in, when the shark comes, throw your buddy at him!). Not
all prey items defend themselves per say, but reproduce in such numbers that
a reasonable amount of the population is likely to survive to breed.
(Also, with the enlarged nasal regions in all euhadrosaurs, they probably
had a better chance of smelling a tyrannosaurid coming some ways off).
