The intermediate option (I love that too, considering it as an alternative one):

The book was designed with slide sheets with lineart drawn skeleton and inner organs in the same poses, that could be placed over the color illustration with matching.
Brachiosaurus, the giant prehistoric herbivorous pangolin.
Also there is seen a little raptor.
