You'll love this throwback to the time when dinosaurs walked the land- our T-Rex has lighted eyes that glare and teeth that flash, and weighs less than 8 ounces! The original T-Rex lived over 65 million years ago in the Cretaceous period. Their bones have been found in the Western parts of North America. Weighing 5 to 7 tons and measuring up to 40 feet in length, it's massive head had 6-inch serrated teeth. Perfect for ripping the flesh from it's victims. Ouch! (Designed to fit all sports helmets).
