Instructables user DIYtime went prehistoric last Halloween and made a costume inspired by the raptors in Jurassic Park. DIYtime detailed the process of making the head portion of the costume; they used the ever popular EVA foam, silicone caulking, Model Magic, a camera/LCD screen and other items. The camera is wired into the nose and the screen is built into the head rig. He designed the dino so the head could be controlled with steel rods. He explained the base of the head:

The head base consists of a EVA foam frame. It’s arranged in a upside down “T” structure with supports at a 45* angle. Then I put a piece to reinforce the lip. Then the whole thing was covered in foam batting and trimmed to shape.

The lower jaw is made with a similar “T” structure as the base of the head and then covered in foam batting. The inside of the mouth is lined with batting as well, though it is shaped to act as a base for the gums. The jaw is then attached using a pin made of a steel rod. To do this I used a blow torch to burn a clean level hole through the jaw’s struts and the bases sides. You can see the struts I’m talking about in both pictures, it’s the yellow portion. Now cover the lower jaw in batting. Additionally the gum flap between the jaws can made with scrap batting and a thin, bent piece of EVA to ensure it folds inward correctly.
