Invertebrate lineages tend to originate and become extinct at a higher rate in onshore than in offshore habitats over long temporal durations (more than 10 Myr), but it remains unclear whether this pattern scales down to durations of stages (less than 5 Myr) or even sequences (less than 0.5 Myr). We assess whether onshore–offshore gradients in long-term turnover between the tropical Eocene and the warm-temperate Plio-Pleistocene can be extrapolated from gradients in short-term turnover, using abundances of molluscan species from bulk samples in the northeast Atlantic Province. We find that temporal turnover of metacommunities does not significantly decline with depth over short durations (less than 5 Myr), but significantly declines with depth between the Eocene and Plio-Pleistocene (approx. 50 Myr). This decline is determined by a higher onshore extinction of Eocene genera and families, by a higher onshore variability in abundances of genera and families, and by an onshore expansion of genera and families ... : Supplement-Eocene abundance dataSpecies-level abundance data from 106 Lower and Middle Eocene stations, assigned to genera and families.Supplement-Plio-Pleistocene abundance dataSpecies-level abundance in 48 Pliocene and Pleistocene stations, assigned to genera and families.Supplement-Eocene station dataSupplement-Plio-Pleistocene station data ...
