Among social insects, army ants are exceptional in their voracious coordinated predation, nomadic life history and highly specialized wingless queens: the synthesis of these remarkable traits is referred to as the army ant syndrome.

Here we report the oldest army ant fossil and the first from the Eastern Hemisphere (EH) |
