Using the most comprehensive existing data set of Phanerozoic marine invertebrate fossil occurrences, we demonstrated strong secular trends in the relative frequency of ecological groups. Our results therefore suggest that Phanerozoic-scale patterns in ecological proportions were not driven by ecological interactions (as is often assumed), and therefore have broad implications for evolutionary and ecological theory.

We confronted a common problem in macroecological studies known as sampling partiality, in which broad-scale relationships are inferred from data collected at scales that do not fully encapsulate a variable of interest (a well-known example being the range sizes of animals). We found that several unavoidable sampling artefacts related to partiality can lead to spurious conclusions, and presented possible solutions to this widespread and common problem.](research_paleoecology_files/shapeimage_1.png)
