A 113-Million-Year-Old ‘Hell Ant’ Fossil Was Just Discovered – Here’s What It Tells Us About Ancient Predators! – Indian Defence Review

A newly discovered 113-million-year-old fossil of Vulcanidris cratensis, a hell ant species from the Cretaceous, reveals complex predatory behaviors and challenges our understanding of early insect evolution.
A remarkable new fossil discovery in Brazil has shed light on the evolution of ants during the Cretaceous period. Vulcanidris cratensis, a new species of “hell ant”, has been uncovered, offering unprecedented insight into these ancient, predatory insects. The fossil was found in the Crato Formation, a renowned site known for its excellent fossil preservation. The discovery, as detailed in a study published in Current Biology, has provided researchers with the oldest definitive evidence of ants, dating back to approximately 113 million years ago.
This new species was identified from a remarkably well-preserved specimen, which shows that Vulcanidris cratensis was part of an extinct subfamily of ants called Haidomyrmecinae, famous for their bizarre predatory adaptations. The fossil was discovered by Dr. Anderson Lepeco and his team while examining a vast collection of fossil insects from the Crato Formation, a site famous for preserving a range of ancient life forms with astonishing detail.
A Significant Discovery: The Oldest Known Ant Species
According to Dr. Lepeco, the fossil represents the earliest undisputed record of ants. “What makes this discovery particularly interesting is that it belongs to the extinct ‘hell ant,’ known for their bizarre predatory adaptations,” he said. Despite being part of an ancient lineage, Vulcanidris cratensis already exhibited highly specialized anatomical features that suggest unique and complex hunting behaviors, setting it apart from modern ant species.
Before this find, the oldest known ant fossils were preserved in amber from regions like France and Myanmar. However, the discovery of an ancient hell ant fossil in limestone has opened new avenues for understanding the geographical distribution and evolutionary development of early ants. Dr. Lepeco emphasized the significance of this discovery: “Even though there have been hell ants described from amber, this was the first time we could visualize this in a rock fossil.”
The “Hell Ant” Features: Complex Adaptations
Vulcanidris cratensis exhibits several unique features that highlight the complexity of predatory behavior in ancient ants. One of the most striking characteristics is its feeding apparatus. Unlike modern ants, which have mandibles that move laterally, this species had mandibles that ran forward, parallel to the head, with a facial projection anterior to the eyes. This specialized anatomy likely enabled the ant to engage in unique predatory strategies, different from the modern ants we are familiar with today.
The fossil’s intricate morphology suggests that even in the Early Cretaceous, ants had already developed highly effective hunting techniques. This challenges previous assumptions about how quickly these insects developed complex adaptations and specialized behaviors. “The intricate morphology suggests that even these earliest ants had already evolved sophisticated predatory strategies significantly different from their modern counterparts,” said Dr. Lepeco.
A Global Presence for Early Ants
The discovery of Vulcanidris cratensis also raises important questions about the global distribution of ants during the Cretaceous period. Despite being part of a now-extinct lineage, this species demonstrates that ants were likely widespread and diversified early in their evolution. The findings suggest that ants had already crossed landmasses and had begun to thrive in diverse ecological niches long before the mass diversification of modern ant species.
Dr. Lepeco explained, “The discovery of this new ant specimen raises broader questions about the evolutionary pressures that led to the hell ant’s unique adaptations.” As research on these early ants progresses, it may provide new insights into the evolutionary forces that shaped the diversity of ants we see today.
