Ourasphaira giraldae is an extinct process-bearing multicellular eukaryotic microorganism. Corentin Loron argues that it was an early fungus. It existed approximately a billion years ago during the time of the transition from the Mesoproterozoic to Neoproterozoic periods, and was unearthed in the Amundsen Basin in the Canadian Arctic.[1][2][3][4] This fungus may have existed on land well before plants.[4]
