These models represent how the dinosaurs may have looked. We have only fossil remains of these animals so it is sometimes difficult to say exactly how they actually looked. Scientists piece the remains together and then "flesh" them out with muscle, fat and skin (and often, missing bones). Different scientists sometimes have slightly different visions of the live animals. In addition, these pictures do not help us understand how big the animals were. Pictures you see or models you have may look different from these models. Find the key characteristics of each dinosaur to match your picture or model to the ones here.

Key Characteristics
