Yeah - it was a speculation that had little basis in fact.
Not only did the water have its own large predators (giant crocodile),
there really is no reason to assume that large theropods could not swim.
Thus running into the water probably wouldn't get them away from a
Now, there is evidence that _Edmontosaurus_ frequented watery places,
but that was probably to feed, not to escape predation. (And most
other hadrosaurs do NOT have this association with swamp habitats).
The peace of God be with you.
