Temporal variation in marine dissolved silica (DSi) levels, in the context of other major environmental and biotic changes over this interval. Representation of inferred temporal changes in DSi follows Ref.²⁵. Changes in the relative abundance of seafloor substrate type (matgrounds, firmgrounds, and mixgrounds)²⁷ are indicated in the lower bar. The spindle plot represents the evolutionary diversification of major clades (modified after Ref.⁷³).
