Largest ant species ever
<i>Titanomyrma giganteum</i>
Germany ()

The largest species of fossil ant is the aptly named Titanomyrma giganteum ("gigantic titan ant"). Queens of this species measured 6 cm long, with a wingspan of 15 cm. A stingless species, it was discovered in the Messel shales of Germany, and dates back 49.5 million years (to the Eocene epoch). A second, smaller species, T. simillima, has also been found in the Messel shales.
