Oecophylla brischkei

Introduction

Oecophylla brischkei is an extinct weaver ant known from Baltic and Bitterfeld amber, dating to the Late Eocene epoch roughly 34 to 40 million years ago . This fossil species represents an advanced stage in weaver ant evolution, with workers showing specialized adaptations for life in the forest canopy . The fossil record reveals a fully developed digestive system identical to modern weaver ants, proving that their social feeding behavior and colony organization were already established tens of millions of years ago . Workers coexisted with other ant species like Oecophylla crassinoda, occupying distinct ecological niches based on differences in mandible structure and body proportions .
