A giant ant, big enough to use in a science fiction movie, was found fossilized in rock that is about 50 million years old. The ant was a queen that was an amazing two inches long—really dinosaur-sized for an ant. Discovered in Wyoming, this is the largest ant ever found in the Western Hemisphere.
Note: there never have been people-sized ants, except in science fiction. Two inches long is huge for an ant, even in pre-historic times!
