Are all dinosaur fossils 'replicas'?

I went to a small 'dinosaur museum' last summer in South Bend Indiana. I wasn't expecting much, but found myself disappointed that all the large displays (except one) were 'replicas'. I'm not sure why I felt this way, since all fossils are 'copies'. But 'replica' makes it seem fake.

edit: I think this is being misinterpreted. In my mind, all fossils are 'copies' of the original. The bone is gone, replaced by stone. But for some reason, calling something a replica doesn't carry the same...majesty as the original copy. Maybe it's just the thought that it could have been tampered with when making it out of plastic or fiberglass.
