Titanomyrma lubei

Titanomyrma is a fossil genus of giant ant. The latest species to be discovered, Titanomyrma lubei, was described in 2011, when a 49.5 million year old fossilized winged queen ant was found in Wyoming. This fossil is the first body of a giant ant found in the Western Hemisphere. The presence of Titanomyrma in North America is considered to indicate "the first reported cross-Arctic dispersal by a thermophilic insect group".
