The Giant Ants are prehistoric insects featured in Impossible Pictures.
Titanomyrma was a genus of giant ant. The latest species to be discovered, T. lubei, was described in 2011, when a 49.5 million year old fossilized winged queen ant, comparable in size to hummingbirds, was found in Wyoming. This fossil is the first body of a giant ant found in the Western Hemisphere. The presence of Formicium in North America is considered to indicate "the first reported cross-Arctic dispersal by a thermophilic insect group".
Another fossil species of this genus, F. giganteum, is the largest known fossil or extant species of giant ant in the world. They resemble the ants from what we have today but 50 times bigger. They were based on real-life Titanomyrma extinct giant ants.
In Walking with... series
Titanomyrma appeared in the first episode of Walking with Beasts (they are named Giants Ants), where they had successfully attacked and killed a Gastornis chick. Just like their real-life counterparts, the giant ants of WWB died-out at the end of the Eocene epoch, when the global jungles vanished, and the global oxygen levels and temperatures dropped.
- It is the only giant bug featured in the Walking with... series that is not from the Carboniferous period.
