From Carolyn, "Original idea for Halloween costume for my 10 year old daughter. Was originally intended to be a crocodile, modified from an idea found online. Box for the head seemed too short for croc and looked more like T-Rex, so T-Rex it was. Won for most scary costume in the fourth grade."
You can find her directions for making this T-Rex costume here.
