Occurrence data used for all analyses in paper
datasetposted on 24.11.2019 by Michael Foote, Arnold Miller
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
The data for most fields come without modification from the Paleobiology Database. In cases where a genus name is used in association with more than one higher taxonomic name, we attempted to resolve the taxonomic assignments as described in the publication. Such assignments are indicated by a hyphenated name in the Genus field, for example "*Bela*-Gastropoda" and "*Bela*-Hexactinellida." These also required modification to the Class field in some instances. After the publication had already gone to production, we noticed that we had incorrectly assigned 26 occurrences of two genera. The corrected data are given here, with the class and genus names indicated by a leading asterisk. We have repeated the analyses and found only the most trivial of differences in the results; our substantive conclusions are therefore unaffected. We assigned collections to our operational time intervals using the full spectrum of downloaded stratigraphic fields. Most of our assignments to the standard intervals of the Paleobiology Database came directly from the downloaded "collections.10_my_bin" field, but we consulted other fields if this field was blank. Some collections could be assigned to one set of time intervals but not the other; these are indicated by "NA" in the appropriate field.
