Revealing mistake: When the group stops to watch the Brachiosaurus, its CGI head clips through the branches of the tree, and the body becomes transparent. A close-up is provided, though it's not necessary at all when watching it on screen.
Suggested correction: There is no clipping. When his head is turned, its head is in front of the branches, and when he starts looking forward and goes on his hind legs, its head is behind the branches.
I don't see any superimposing. Its head is in front of the branch. It's even clearer in the moving scene, no superimposing to spot. Is this screenshot from the VHS version? Because if it's not visible there, it won't be in any other version either.
