I have to disagree here. Most sharks aren't. Some school and there have been
studies showing that sharks, regardless of their brainsize have an intelligence
as high as many birds. Now if birds can hunt in effective packs then so can
sharks (they just seem not to prefer it) and so could Deinonychus. There were
even studies done that showed that smaller brains were very effective indeed.

Because contrary to popular belief, sharks aren't stupid.
That's as far as I go into this thread. My only thought on the Deinonychus vs.
Tenontosaurus bit is that maybe it was a fluke.
A pack of Deinonychus come down to eat a dead (or dying) Tenontosaur in a bad
part of town.
Wouldn't have gotten involved, but the stupid shark view had to go.
