To scale
The bars are drawn to the same scale. On these pages the animals are sized in proportion to each other as far as a screen allows: the giants are shrunk a little and the smallest are enlarged, so that you can see them all.
Good to know
Its wings spanned about as much as a small aeroplane.
Standing on the ground, it was about five metres tall.
It probably stalked across open ground like a giant stork, picking up small animals.
Quetzalcoatl was the feathered serpent god of the Aztecs.
It is thought to have vaulted into the air with its arms in under a second.
Once up, it may have glided for thousands of miles.
