Quetzalcoatlus (ket-zel-KWAT-a-lus) Meat eater, 35 feet wide, late Cretaceous period. 65 million years ago located in western North America, Montana. Quetzalcoatlus was the largest animal that ever flew. It was as wide as a fighter jet.

Quetzalcoatlus is also the name for a feathered flying god worshiped by the Aztec civilization of Mexico.
