Exactly 113 Million Years Old: Scientists Uncover the World's Oldest Ant Fossil!

A New Era Begins with Ancient Ant Fossil in Brazil

Located in the northeast of Brazil, 113 million years A fossilized ant dating back to 1000 BCE could change a lot about ant evolution. The discovery represents one of the oldest records in ant history. The fossil, Haidomyrmecinae belonging to the subfamily and unofficially “hell ants” This fossil stands out as an important discovery that will help us understand the diversity and spread of ants in the Cretaceous period.

Discovery and Importance of Fossil

Author Anderson Lepeco“Our team has discovered a new fossil ant species that represents the oldest undisputed geological record of ants,” he said. “The intimidating appearance and unusual jaw structures of hell ants provide new clues about their hunting techniques. Despite being part of an ancient lineage, the fossil exhibits highly specialized anatomical features.”

Amber and Limestone: Where Fossils Are Found

“Although hell ants have been depicted in amber, this is the first time we have been able to visualize this in a rock fossil,” Lepeco said, sharing the details of the discovery. The fossil was found in a limestone layer in the Crato Formation of Brazil, known for its extraordinary preservation properties. This once again highlights Brazil’s richness in fossils and the importance of research in this field.

3D Reconstruction and Anatomical Features

The team used micro-computed tomography imaging to image the fossil 3-dimensional reconstruction. In the process, remarkable anatomical features were revealed. Instead of the side-to-side swinging jaws of modern ants, this ancient hell ant has forward-projecting jaws. It also has a horn-like protrusion on its head, ideal for gripping prey. These features are crucial to understanding its hunting strategies.

Ant Biogeography and Gondwana

The features of this particular fossil ant found in Brazil are similar to those of fossil hell ants discovered in Burma, suggesting that hell ants were much more widespread during the Cretaceous period than previously thought. The presence of such an ant in South America contradicts previously established restrictions on ant distribution in Eurasia, suggesting that ants were dispersing across continental landmasses long before the breakup of Gondwana.

The Future of Fossil Research

This finding highlights the importance of a comprehensive study of existing collections (both private and museum). Brazil’s paleontological riches contain countless fossils and insect faunas waiting to be discovered. By studying such fossils, the team aims to learn more about ancient ecosystems and understand the factors that influenced the evolutionary history of ants.

New Perspectives on Ant Evolution

Ant evolution is a very long process, and this fossil offers new perspectives on how evolution occurs. Studies on the adaptations, hunting strategies and ecosystem roles of hell ants in particular are of great interest to the scientific community. Research on these species can provide important information not only about ants, but also about the evolution of other insect species.

Brazil's Fossil Wealth and Research

Brazil’s rich fossil deposits are making such discoveries more likely. Areas such as the Crato Formation have become a magnet for paleontologists worldwide. Research in such areas provides critical information about ancient climates and ecosystems. Fossil research raises awareness of biodiversity conservation and provides an important resource for future generations.

In summary, this ancient ant fossil from Brazil contributes to the scientific world by providing in-depth information about ant evolution and biogeography. The new findings will expand our understanding of the evolutionary history of ants and shed light on future research.
