Discover the Dinosaur-Era ‘Last of Us’ Fungus: Stunning Amber Fossil Unveils Ancient Secrets

A remarkable discovery in 99-million-year-old amber has revealed a fly trapped along with a parasitic fungus that emerged from its head. This unusual find also includes a young ant infected with a similar fungus. These specimens are some of the oldest known examples of fungi that control their hosts before eventually leading to their demise.

Yuhui Zhuang, a doctoral student at the Institute of Paleontology in China, noted that amber fossils offer a unique window into ancient ecological relationships. “These two fossils are exceptionally rare among the thousands of amber specimens we’ve studied,” he said. Researchers identified two new species of ancient fungi from this find, named Paleoophiocordyceps gerontoformicae and Paleoophiocordyceps ironomyiae.

Strikingly, some modern Ophiocordyceps species are dubbed "zombie-ant fungi" as they manipulate the behavior of ants. This phenomenon is gaining attention; for instance, it inspired the popular video game that influenced HBO’s series, "The Last of Us." Zhuang adds that these ancient fossils suggest that complex ecosystems were already developing millions of years ago, hinting at the role of these fungi as early predators in the Cretaceous period.

Conrad Labandeira, a scientist at the Smithsonian Museum, explained that the modern Ophiocordyceps fungus interacts with carpenter ants by entering their brains to control their actions. Labandeira suggests that the ancient fungi likely had similar methods.

Interestingly, the prevalence of parasitic fungi varied through time. Today, they mainly target ants, while flies are infrequently infected. This makes the fossilized remains of the infected fly particularly significant. João Araújo, a mycology curator involved in the study, noted that the two insects probably died from the fungi before getting trapped in amber.

Historically, these fungi played an essential role in shaping ecosystems. Phil Barden, an associate professor at New Jersey Institute of Technology, pointed out that while amber reveals fascinating organism diversity, it also captures just a tiny fraction of the past.

This discovery provides an intriguing look at how nature’s mysteries, like parasitism, have roots in our planet’s history. It also highlights the ongoing exploration of ancient amber, particularly from Myanmar, which has emerged as a rich source of paleontological finds, despite ethical debates surrounding its sourcing.

The study reinforces the understanding that interactions between species have existed for millions of years and continue to influence ecosystems today.
