Amber’s 99 million-year-old glove preserves ancient flies at horror shows. A mushroom-like fruit body of zombie bacteria is popping out of its head.
The insects are two of the oldest examples of strange natural phenomena, including a second specimen of young ants infected with similar fungi, as well as fungal parasites that hijack the host’s body before they are ultimately killed.
“Amber gives us this opportunity to visualize ancient ecological relationships preserved in fossils,” said Yuhui Zhuang, a doctoral student at the Institute of Paleontology at Yunnan University in southwestern China.
“Overall, these two fossils are extremely rare, at least among the tens of thousands of amber specimens we’ve seen, with only a few conserving the symbiotic relationship between fungi and insects.”
Zhuang and his colleagues appointed two ancient fungi from two unknown species of the genus Ophiocordyceps from Amber’s study. They found the first and second Paleoophiocordyceps ironomyiae on the spot, named the archaic geerontoformicae in Ant.
Several Ophiocordis species that prey on today’s ant species are known as “zombiant bacteria.” Because fungal parasites can manipulate host behavior for their own benefit. This phenomenon has affected the video games behind the HBO television show The Last of Us. HBO shares parent company Warner Bros Discovery with CNN.
“The discovery of these two fossils suggests that terrestrial ecosystems are already very complex and may have begun to act as “predators” of insects, particularly during the Cretaceous period, and have begun to regulate populations of certain groups.
Zombie bacteria were then and now
According to the Natural History Museum in London, the parasitic bacteria, also known today as insect pathogenic bacteria, infects a wide range of insect groups, including ants, fly, spiders, deer and beetles.
In the case of carpenter ants, the spores of Ophiocordis land on the ant’s head and enter the brain through weak areas of the insect’s exoskeleton, taking control of the ant to promote its spread.
According to Labandeira, Paleoophiocordyceps likely zombified its host in a similar way.
“For some reason, ants appear to have been targeted early for zombie transformation and are now the main recipient of this parasite,” Lavandeira said. He added that flies are rarely affected by these parasitic bacteria today, making the example of fossilization of particular interest.
Fungal species infected with prehistoric ants may be ancestors of zombie ants and therefore are likely to control the host body in a similar way, said Mycology Kurtor and assistant professor João Araújo of the Danish Museum of Natural History. Very little is known about their evolution, as specimens of ancient parasites have been found.
The two insects are likely killed by fungi before being trapped in the sticky wooden resin that eventually forms amber, Arauho said.
This lost parasite diversity played a key role in shaping the planets we live in today, said Phil Burden, an associate professor in the Department of Biological Sciences at New Jersey Institute of Technology.
“Even if we find a noticeable diversity of organisms seeped into amber, it’s important to remember that we only capture the smallest glimpse. For a particular fossil ants or beetles, we can imagine that such insects are supported by all parasites, fungi and bacteria.
“They’re also known as Edmund Jalsenbowski, co-author of Edmund Jalsenbowski, professor and associate scientist at the Museum of Natural History in London,” said Edmund Jalsenbowski, co-author of Edmund Jalsenbowski, co-author of Edmund Jalsenbowski, a professor and associate scientist at London’s Museum of Natural History.
The fossils are the latest to emerge from Myanmar’s rich Amberfield.
While amber fossils have been some of paleontology’s most exciting discoveries in recent years, ethical concerns have emerged about Amber’s origins from Civil War-torn regions.
Zhuang said the fossils were sourced from the mber market in Myanmar. This study noted that the specimen was acquired prior to 2017 and was not involved in armed or ethnic conflicts due to the author’s knowledge.
