Ultra-detailed ancient ant revealed in amber through 3D imaging

Researchers studied two amber pieces from the Goethe National Museum containing a fungus gnat, a black fly, and an extinct ant, †Ctenobethylus goepperti. Using advanced 3D imaging, they reconstructed the ant’s morphology and interior anatomy, revealing fine body hairs and enabling detailed comparisons with living Liometopum ants to infer possible canopy-nesting behavior. The findings, published in Scientific Reports, provide a clearer picture of how this ancient species lived.

Ancient Fossil Suggests Spiders Once Had Tails and May Still Do

Scientists discovered a 100-million-year-old fossil of a spider in Myanmar amber that had a tail, revealing that ancient spider ancestors possessed tails, a trait previously only hypothesized. The fossil, named Chimerarachne yingi, shows a blend of ancient and modern features, including spinnerets and a tail similar to early arachnids, suggesting web-building evolved later. The discovery provides new insights into spider evolution and raises the possibility that similar species might still exist in unexplored rainforests.

Ancient Forest Preserved in 112-Million-Year-Old Amber

Scientists have discovered 112-million-year-old amber samples from Ecuador that contain well-preserved 3D snapshots of ancient insects, including beetles, flies, and spiders, providing valuable insights into prehistoric life and the early relationship between flowers and pollinating insects. These bio-inclusions are rare and help scientists understand the biodiversity of the Gondwana supercontinent era.

Tsunami Displaces Tree Resin and Amber to Seabed

A recent study in Japan revealed that a massive tsunami during the age of dinosaurs transported tree resin and amber from inland forests into deep-sea environments, providing new insights into ancient tsunami events and their impact on coastal and deep-sea ecosystems. The findings suggest that such tsunamis could have been triggered by landslides and tectonic activity, and that amber can serve as a valuable marker for identifying past coastal disasters, with implications for understanding long-term climate and hazard risks.

Ancient Amber Unveils Antarctica's Prehistoric Rainforest Past

Scientists have discovered amber fragments in Antarctica, suggesting the continent was once a lush jungle. This finding, supported by fossilized evidence of trees, indicates a vastly different climate in the past, characterized by high levels of greenhouse gases. The study highlights the potential for understanding how life can adapt to extreme environments, offering insights into future climate challenges as carbon emissions continue to rise.
