Help: Ankylosaurus (Origami Fantasy) - Step 72

[Wordgames]

Okay Ive ruined yet another bit of paper on step 72 (page 129), while I can manage steps 66-71 (after a little man-handling) step 72 just does not seem to follow the same rules as 65-71.

Any advice, redrawn diagrams or photos of this stage in progress would be appreciated, thanks!
