In Fig. 141 is shown the complete skeleton 

 of the Iguanodon. This great Dinosaur was one 

 of the first to be discovered. As you see, it stood 

 on its hind legs like a kangaroo, and in running 

 occasionally went on those feet only, touching 

 the ground now and

 fourteen feet from the 

 head to the ground in
