Abstract
Two of the traits most often observed to correlate with extinction risk in marine animals are geographic range and body size. However, the relative effects of these two traits on extinction risk has not been investigated systematically for either background times or during mass extinctions. To close this knowledge gap, we measure and compare extinction selectivity of geographic range and body size of genera within five classes of benthic marine animals across the Phanerozoic using capture-mark-recapture models. During background intervals, narrow geographic range is strongly associated with greater extinction probability, whereas smaller body size is more weakly associated with greater extinction probability. During mass extinctions, the association between geographic range and extinction probability is reduced in every class and fully eliminated in some, whereas the association between body size and extinction probability varies in strength and direction across classes. While geographic range is universally the stronger predictor of survival during background intervals, variation among classes during mass extinction suggests a fundamental shift in extinction processes during these global catastrophes.

METHODOLOGICAL INFORMATION
Every R script file starts with a number and each R script file should be run in numerical order (01-09). R scripts for ESM analysis are also numbered and should be run in order (S01-S16).
DATA-SPECIFIC INFORMATION FOR:
genera_range_through.txt
Text file with raw list of genera with first fossil occurrences (fad; first appearance datum) and last fossil occurrences (lad; last appearance datum) and body size data. Biovolume data is under calc_max_vol column. fad_age and lad_age correspond to the numeric geologic age of first and last occurrences and fad_int and lad_int correspond to the name of the interval in which a fad or lad occur. pbdb_taxon_no corresponds to the number assigned to a taxon by the Paleobiology Database. It is used to match our body size data set with occurrence data from the Paleobiology Database.
