Dilophosaurus was one of the first large predatory dinosaurs on earth. Although this creature was almost twenty feet long it was slender in build and weighed less than half of a ton. A crest over each eye projected at an angle from the animal's forehead. These delicate crests were too fragile to withstand much abuse and were probably used for display.
