In the Ahead-of-Print version published on 26 July 2018, the taxonomic richness curve shown in Figure 2A is incorrectly scaled and placed. The peak in fossil diversity should fall within the late Tonian, not during the Sturtian glaciation event.

The correct version of the Figure appears in the version published in volume 2, issue 2 (pages 173–180) and is also presented here.

(A) Taxonomic richness data for the Tonian and Cryogenian from ref. [18]. (B) Within-assemblage fossil diversity adapted from ref. [17]; orange circles represent the taxonomic diversity of individual stratigraphic units and the blue line is a loess smoothed average of these data. (C) The approximate stratigraphic ranges of major eukaryotic fossil clades. (D) Stratigraphic ranges of major groups of biomineralized and recalcitrant taxa. Abbreviations: ASM, apatitic scale microfossils; VSM, vase-shaped microfossils; Agglut., agglutinated forms. (E) Approximate stratigraphic position of direct evidence of predation; spheres represent acritarchs with perforations; cone-in-cone represents Cloudinid fossil with borings. Blue-shaded bars represent the two ‘Snowball Earth’ events.
