I made line drawings of four individual dinosaur bones, seen above, then asked participants (three second grade classes, in the case of the images shown below) to guess what bones they are and what they are used for. Then the kids drew the rest of the dinosaurs around the bones.
The results so far have ranged from fairly accurate to extremely fantastical, and show a simultaneously impressive degree of understanding about anatomy and an equally impressive willingness to draw completely invented creatures with that anatomy.

Updated images from a range of participants, as well as an analysis of the drawings, will be coming soon.
