Theropods

The word Theropod is used to describe many dinosaurs. Theropod dinosaurs shared a number of characteristics:

-They were all carnivores (meat-eaters) -They all used their back legs for walking and each foot had three toes -Most walked exclusively on two legs -They had hollow limb bones -The humerus (upper arm bone) is less than half as long as the femur (upper leg bone)

There are a number of other, more technical characteristics, but these are the basics.

Theropods, such as Eoraptor, were the very first dinosaurs and they may be the most successful animal design ever created in nature. Modern birds have the same basic structure as these prehistoric animals.
