Statistical correlations of the match between Paleobiology Database sampled diversities and model-based diversity residuals for the same geographical regions based on Spearman Rank. (p, probability; PaleoDB, Paleobiology Database. Statistically significant results in bold.)

	raw	generalized differences
Europe: rock proxy model versus PaleoDB diversity (figure 3a)	ρ = 0.488	ρ = 0.478; p = 0.002
North America: rock proxy model versus PaleoDB diversity (figure 3c)	ρ = 0.478	ρ = 0.416; p = 0.004
Europe + North America: rock proxy model versus PaleoDB diversity (figure 3e)	ρ = 0.320	ρ = 0.417; p = 0.003
Europe + North America: rock proxy model residuals versus SQS diversity from [13] (figure 3g)	ρ = 0.648	ρ = 0.234; p = 0.110
