Named Ourasphaira giraldae, the new species of fungus was found in the Grassy Bay Formation in the Canadian Arctic. Researchers led by Corentin Loron, a PhD student at Université de Liège, identified key fungal features in micrometer-scale fossils extracted from unexplored shale at this remote site.
The discovery, announced in Nature, not only pushes the fossil record of fungi back by about 600 million years, it also suggests that other eukaryotic organisms—a group that includes complex multicellular life-forms like animals—may have originated around the same time as O. giraldae, in the mid-Proterozoic age.
