Look at the view from above, the diorama looks so little next to other statues... Triceratops should have almost the size of a T-Rex, the dino have about 10 meters, in 1/10 should be 1 meter large or close to this, and this diorama is not even close to that, looks more like an elephant size for the scale, I don´t remember very well if in the movie the Triceratops was little like this, maybe a young dino?
