Be thankful that you don't live 50 million years ago, or you'd have to use a baseball bat instead of a shoe to kill this ant:

A winged ant queen fossilized in 49.5-million-year-old Wyoming rock ranks as the first body of a giant ant from the Western Hemisphere, says paleoentomologist Bruce Archibald of Simon Fraser University in Burnaby, British Columbia.

The new species, Titanomyrma lubei, is related to giant ants previously found in German fossils. These long-distance relatives bolster the notion that the climate of the time had hot blips that allowed warmth-loving giant insects to spread from continent to continent, Archibald and a U.S.-Canada team propose online May 4 in the Proceedings of the Royal Society B.
