Pardon the play on words, but the controversy as to how to display dinosaurs in museums has been "a bone of contention" for many years.
On one hand, a plaster, fiberglass, or foam-rubber representation of what we think a dinosaur actually looked like can be an exciting display -- one that can capture the imagination of youngsters and grown-ups alike. And having them move and growl by mechanical means can add to this excitement.
On the other hand, we really don't know what color dinosaurs were -- whether they were a single color all over (like crocodiles) or had stripes or other patterns on their skin (like many lizards and snakes). We also don't know how fully muscled these animals were: some fully fleshed-out dinosaur recreations make them look chubby while others make the same animal look anemic.
And, by the way, we certainly don't know what kind of sounds dinosaurs made!
So the bones are really the only thing we have for sure -- and the argument can be made that a museum should only display what we are reasonably sure of, leaving the recreated dinosaurs to the amusement parks and movies.
