An overlooked fossil in a Brazilian museum has now been identified as the oldest known ant specimen, dating back 113 million years. This discovery has been published in the journal Current Biology.
The fossil, named Vulcanidris Cratensis, was reportedly found in the Crato Formation of northeastern Brazil, a site which is well renowned for its well-preserved fossils. Anderson Lepeco, a researcher at the Museum of Zoology of the University of São Paulo, stumbled upon the specimen in September 2024 while examining the museum's collection. "I was just shocked to see that weird projection in front of this (insect’s) head," Lepeco told CNN.
This ancient ant belongs to the extinct subfamily Haidomyrmecinae , commonly referred to as "hell ants." As per reports, these ants are characterized by their scythe-like jaws, which served as a way to impale a prey. Unlike the previous hell ant fossils found in Myanmar, this one was preserved in rock which made it a rare find.
The discovery suggests that ants were already widespread during the early Cretaceous period. Phil Barden, an associate professor at the New Jersey Institute of Technology who studies insect evolution, commented on the significance of the find. "This new find now represents the oldest ant known; it extends the known fossil record for ants by about ten million years," Barden said via email to CNN.
Micro-computed tomography imaging revealed that Vulcanidris cratensis had anatomical features linking it to wasps, indicating a common ancestry. Its wings had more veins than those of modern ants, and its jaws projected forward from near the eyes, functioning like a "forklift" to capture prey, according to Lepeco.
The fossil's preservation in rock, rather than amber, provides a unique opportunity to study the morphology of early ants. This discovery pushes the timeline of evolution of ant.
In the modern world, ants are among the most abundant insects on Earth, found on every continent except Antarctica. However, they evolved approximately 145 million years ago, diverging from ancestors shared with wasps and bees.
The discovery of Vulcanidris Cratensis sheds light on the early diversification of ants and their role during the age of dinosaurs. It emphasizes the importance of museum collections in uncovering significant paleontological findings.
