>> The biota formed with the Great Oxidation Event, a temporary increase in atmospheric oxygen, and became extinct from marine anoxia when the event was terminated by the drop in oxygen levels of the Lomagundi Excursion Event. The biota represents the earliest known experiment in multicellularity, with no extant multicellular descendants.
