40-Million-Year-Old Ant Discovered in Goethe’s Amber Collection

Researchers from the University of Jena have uncovered three previously hidden fossil insects within the personal amber collection of the renowned German writer Johann Wolfgang von Goethe. While Goethe famously used pieces of amber to study optics and color theory, he remained unaware that his collection contained biological treasures trapped for 40 million years. Using advanced synchrotron micro-computed tomography, scientists were able to peer through the unpolished resin to reveal a fungus gnat, a black fly, and an exceptionally well-preserved extinct ant.

The discovery of the ant, identified as *Ctenobethylus goepperti*, represents a significant advancement in paleontology. The high-resolution 3D scans provided unprecedented detail, allowing researchers to document fine body hairs and internal skeletal structures within the head and thorax that had never been observed before. By creating a comprehensive digital reconstruction, the team has provided a valuable reference model for the global scientific community to better identify and compare similar fossils.

Beyond the anatomical insights, this study sheds light on the behavior of ancient forest ecosystems. By comparing the fossilized specimen to the modern *Liometopum* genus, researchers suggest that these ants likely constructed large arboreal nests. This behavioral trait explains their frequent presence in amber, as their tree-dwelling lifestyle made them more susceptible to becoming trapped in sticky resin. This research highlights how modern imaging technology can transform historical artifacts into vital sources of new scientific knowledge, bridging the gap between 19th-century collections and 21st-century evolutionary biology.
