We've been to the Dinosaur Museum twice with our daughter on visits to Grand Junction--the first time she was 3 1/2 and this time she was 5. She really enjoyed it both times. The film they show is pretty good, Discovery Channel produced it I think. There's a relatively small hall with exhibits, of which several are animatronic dinosaurs, including one that spits water if you're standing on a nearby bridge. That one of course draws all the shrieks of excitement. They also have a "find the fossil" area filled with nut shells rather than sand (so be careful for those with I think it was walnut allergies), and a place where kids can experiment with moving stones around to block the travel of a ball down a waterfall-type-feature. There's also a platform to show what an earthquake feels like. The gift shop is good-sized for the size of the museum. Oh, and there are some scientists/workers there brushing off fossils which is kind of neat. The museum isn't free--We bought a family ticket for four adults and our daughter which I think was $25 or so.
